The extensive evidence behind DMSO’s ability to regenerate spinal cord injuries, treat “incurable” back pain, and transform spinal medicine — and how to use it
Story at a Glance:
- DMSO is an “umbrella remedy” whose combination of therapeutic properties (improving circulation, reducing inflammation, protecting cells, and reviving dying ones) makes it well suited to treat “incurable” neurological disorders, with particularly dramatic results for spinal conditions.
- DMSO is one of the most potent known promoters of microtubule assembly (the structural scaffolding cells require to divide and extend new processes) and drives diverse stem cells to differentiate into neurons, providing a potential explanation for the spinal cord regeneration repeatedly documented throughout this article.
- Extensive animal data and remarkable human case reports show DMSO can prevent or reverse paralysis from strokes, traumatic brain injuries and spinal cord injuries when given promptly, and provide significant rehabilitation even for older injuries. Veterinarians have used IV DMSO for decades to get paralyzed animals back on their feet, yet this knowledge has never been translated to human medicine.
- DMSO has been extensively used in clinical practice for degenerative spinal conditions (disc herniations, radiculopathies, stenosis, osteochondrosis), with hundreds of readers reporting it transforming chronic back pain, sciatica, neck pain, and post-surgical spinal pain, often after years of failed conventional treatments.
- This article will synopsize the extensive data demonstrating DMSO’s efficacy for spinal conditions (approximately 400 studies and 300 pertinent reader testimonials), discoveries we’ve made about neurological diseases over the years, and then concludes with practical guidance on DMSO protocols and complementary approaches that also aid in the treatment of the common neurological and vertebral disorders.
Recently, I summarized approximately 2000 studies and 200 reader reports showing DMSO treats “incurable” CNS neurological diseases (including Parkinson’s, Alzheimer’s, ALS, multiple sclerosis, seizure disorders, psychiatric conditions, and Down syndrome) through its foundational properties: improving all forms of circulation, reducing inflammation, protecting cells from lethal stressors, crossing the blood-brain barrier, and reawakening dormant cells. This article extends that work to the spine, where DMSO’s regenerative properties are perhaps even more dramatic.
Remarkably, veterinarians have been using IV DMSO for spinal and neurological conditions in animals for decades. When a horse goes down and can’t get up from a severe neurological problem, IV DMSO is often standard practice. When a dog is hit by a car and paralyzed, many reports exist of IV DMSO routinely getting them walking again. Multiple veterinarians who contacted me described personally witnessing “miraculous recoveries” in paralyzed animals, and veterinary textbooks from the 1980s already listed IV DMSO protocols for brain and spinal cord injuries. Yet in human medicine, a spinal cord injury patient is told nothing can be done and to prepare for a life of severe disability.
As I will show, the answer to Todd’s question is not that DMSO doesn’t work in humans. It is that the FDA effectively prevented it from ever being properly tested, and the medical profession never looked at what veterinarians already knew.
Note: the night before I published this article, one DMSO doctor I correspond with shared with me “I just heard from my patient that he had a cow that was found down, completely unconscious with a heartbeat. He called his vet who told him to mix DMSO and saline and infuse it. Within 30 mins, the cow was back up like nothing happened and lived until they sold it off.”
Neural Regeneration
In purified tubulin systems, DMSO lowers the critical protein concentration required for their assembly into microtubules 8- to 10-fold (from 9.4 μM to 1.1 μM), primarily by reducing the rate at which tubulin subunits detach from growing ends while leaving the attachment rate unchanged. At optimal concentrations (6-12%, with 8% identified as best), 10% DMSO enabled microtubule formation at protein concentrations as low as 1 mg/ml (conditions under which assembly otherwise completely fails), producing microtubules that were morphologically and chemically identical to normal ones (GTP-dependent, cold-sensitive, inhibited by colchicine and calcium) but lacking the microtubule-associated proteins (MAPs) that normally coat them, an important advantage in spinal cord injuries where MAPs are frequently damaged or lost.1,2,3 These results have been confirmed across numerous systems: DMSO enabled assembly from tubulin completely stripped of associated proteins,1 reversed the complete blockade of microtubule assembly caused by rotenone1 (a Parkinson’s-causing pesticide), facilitated polymerization without added nucleotide,1 dose-dependently slowed disassembly,1 promoted rapid self-organization into polarized assemblies in Xenopus egg cytosol,1 progressively stabilized microtubules against cold-induced depolymerization at higher concentrations,1,2,3 modified lattice structure to promote more stable and organized spiral assembly,1,2 and greatly stimulated assembly in cobalt-containing systems.1
Most notably, plant protoplasts (cells with their walls removed) that had completely lost their cortical microtubule networks and were unable to divide were treated with 2-7% DMSO. Within hours, DMSO reinstated a dense, three-dimensional cortical microtubule network visible by immunofluorescence as long microtubule bundles with increased tubulin content. This structural restoration triggered continuous cell divisions that had never occurred under any other conditions, and the effect was so robust that unlimited tissue could be generated from protoplasts that had never produced even a single colony in control experiments. DMSO outperformed all other microtubule-stabilizing compounds tested (and a separate study confirmed that even 1% DMSO dramatically promoted early cell divisions, with 10-45% division rates vs. approximately 5% in controls).
In cultured arterial smooth muscle cells, 1% DMSO stabilized cytoplasmic microtubules so effectively that the network resisted both colchicine-induced depolymerization (which DMSO has been repeatedly shown to counteract1) and the growth-factor-triggered depolymerization that normally initiates cell division, effectively locking the cytoskeletal architecture in a stable, non-dividing configuration (a beneficial effect in vascular tissue, where uncontrolled proliferation drives disease). Prolonged exposure at the same concentration produced dramatic increases in microtubule quantity, with high DMSO doses driving polymerization faster than cells could complete normal assembly, while 1% DMSO also prevented neutrophil-induced endothelial stiffening and pathologic cytoskeletal remodeling.
In neurons specifically, DMSO supported axoplasmic microtubule assembly in squid giant axons, enhancing peak sodium conductance and shifting voltage-dependent activation toward more negative potentials, implying microtubule integrity directly modulates the ion channels that generate nerve impulses (DMSO also altered the structural organization and transport behavior of tubulin within axons, accelerating its movement and effectively accelerating a normal physiological differentiation process in cytoskeletal transport).
Finally, when leukemia cells were pretreated with microtubule-disrupting drugs (colchicine or vincristine), DMSO-induced differentiation (making the cancer become non-cancerous) was delayed, indicating that intact or stabilized microtubules are required for DMSO to drive cellular maturation.
Note: DMSO’s microtubule-stabilizing effects extend across many biological systems, including improved development rates in fertilized eggs,1 preservation of brain microtubules for electron microscopy,1 promotion of microtubule aster formation in Xenopus egg extracts,1,2 stimulation of stathmin/Op18 hyperphosphorylation (a key regulator of microtubule dynamics), and simultaneous induction of microtubule bundling and defense signaling in grapevine cells (demonstrating its cytoskeletal and membrane effects are functionally coupled). DMSO also reversibly altered the electrical surface charge of tubulin and microtubules in a dose-dependent manner, though at therapeutically realistic levels the charge remained negative with preserved polymer stability.1,2,3,4,5
In short, DMSO dramatically lowers the threshold for microtubule assembly, stabilizes the resulting structures against depolymerization, and in living cells restores the structural scaffolding required for cell division and axonal extension. So, for damaged nervous tissue, where regeneration is often prevented by an inability to rebuild this cytoskeletal infrastructure, this represents a direct mechanistic explanation for the regenerative effects repeatedly seen from DMSO.
DMSO (typically at 1.5–2%) has also been shown across dozens of in vitro studies to induce neural differentiation — confirmed by neuronal marker expression and neurite outgrowth — in bone marrow mesenchymal stem cells,1,2,3,4,5,6,7,8,9,10, 11,12,13,14,15,16,17,18,19,20, 21,22,23,24,25,26,27,28,29, 30 umbilical cord and cord blood mesenchymal stem cells,1,2,3,4,5,6,7 adipose-derived stem cells,1 pig embryonic stem cells,1 nasal-derived stem cells,1 dental pulp stem cells,1 periodontal ligament stem cells (into Schwann-like cells),1 amniotic fluid and amnion mesenchymal stem cells,1,2 gingival fibroblasts (which then secreted dopamine and acetylcholine),1 reaming debris-derived stem cells,1 and numerous neuroblastoma cell lines.1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23
Additionally, a 24-hour DMSO pretreatment rescued age-related neural differentiation deficits in induced pluripotent stem cells from older donors.1,2
Mechanistically, DMSO promotes the maturation of already-committed neuronal precursors rather than stimulating proliferation. One study found it selectively doubled the number of hypothalamic neurophysin-positive neurons without inducing DNA synthesis, with a consistent 6-day lag indicating differentiation of post-mitotic precursors.1 This process is driven by rapid suppression of cyclin-dependent kinase activity (particularly CDK6), accumulation of active retinoblastoma protein, and a dose-dependent shift toward G₀/G₁ phase with reduced S-phase cells1,2,3,4 — all of which modulate the cell-cycle exit to permit terminal neural differentiation (while alternatively, DMSO will also switch cells to the S phase for tissue injury repair and promote proliferation1). DMSO also selectively promotes synaptogenesis, increasing synaptic vesicle protein (synaptophysin) relative to general neuronal markers, suggesting it enhances synaptic connectivity beyond simply generating neurons.1
Note: some evidence suggests DMSO’s primary action on stem cells is structural (cytoskeletal reorganization) rather than transcriptional, as one study found DMSO-induced morphological changes reflected cytoskeletal reorganization rather than classical gene-expression-driven differentiation,1 and another found DMSO decreased neurotrophic factor expression,1 which would explain why DMSO-treated stem cells differentiate appropriately when transplanted into animals or humans but show variable marker expression in isolated culture.
Beyond DMSO alone, DMSO combinations have further enhanced neural differentiation (e.g., FAD,⬖ resveratrol,⬖ BDNF, a cAMP derivative1,2 and a ginsenoside⬖) and promoted neural stem cell proliferation (e.g., Schisandrol A,⬖ rapamycin a cAMP derivative1,2 and intracerebroventricular CXCL1), which jointly were shown to directly facilitate motor recovery after a spinal cord injury.1,2 Additionally, DMSO-differentiated neuronal cells have been used as a screening platform to identify compounds that promote neurite outgrowth in damaged central nervous system neurons.
Note: for reader ease, I use ⬖ to designate natural substances DMSO is therapeutically combined with (in part to provide ideas for people who want to explore combinations at home).
Spinal Cord Injuries
My son took dmso after his complete spinal cord injury c1/c2 was told would never breathe move his arms or legs. I got him dmso he is walking


The greatest benefit occurs when DMSO is given within 90 minutes of injury, with higher doses also increasing the speed and likelihood of recovery.1,2,3 However, DMSO can often provide significant rehabilitation for far older injuries (e.g., an engineer who had been paralyzed made remarkable improvements from DMSO 12 years later, and a college student with severe injuries including a C4-C5 fracture who began DMSO nearly two years post-injury gradually regained sensation, limb movement, and hand function over the following years—whose progress halted when the FDA unconscionably revoked DMSO’s medical use—but nonetheless healed enough to graduate).
Likewise, one reader shared that his feet had been paralyzed for 13 years; after starting oral DMSO, he was walking without braces after three months and a veterinarian who practiced in the 1970s reported personally witnessing “many miraculous recoveries” in dogs and cats paralyzed after being hit by cars after they received IV DMSO.
Animal Evidence
Dexamethasone, reserpine, and hypertonic dextrose provided no benefit.1,2,3,4,5,6,7

Many subsequent studies found similar results. In blunt spinal cord trauma, DMSO consistently improved motor function, reduced edema and oxidative stress, and preserved neural tissue: in rabbits DMSO accelerated recovery of hind leg motor function, normal urination and defecation, and repair with new skeletal tissue (while untreated rabbits showed no motor recovery), in cats DMSO improved functional recovery by 169.57%,1,2,3 and in rats DMSO reduced free radical content and increased antioxidant activity while improving hindlimb motor function by 24-96 hours.1,2,3 Topical epidural application of DMSO also produced significantly better motor performance compared to saline controls.1 Additionally, in cats with gradual spinal cord compression, DMSO restored somatosensory evoked potentials and half regained some ability to walk, with a separate study confirming DMSO was effective for chronic spinal cord compression.1,2,3 IV DMSO also significantly extended the time available before omental transposition surgery (from 3 hours to 6-8), outperforming every other existing therapy. In another rat contusion study, DMSO significantly improved motor function and somatosensory-evoked potentials compared to methylprednisolone or naloxone, producing the greatest clinical improvement over 14 days.1
When the spinal cord was transected (cut), DMSO following the injury was found to be superior to both hyperbaric oxygen and placebo in allowing rats to avoid paralysis and in reducing subsequent spinal cord damage (less scarring, collagen formation, and damaged nerve fibers),1,2 with a third study finding DMSO prevented pathological spinal changes hypothesized to result from DMSO removing fluid pockets that had eliminated the space nerves needed to regrow (and DMSO also significantly enhanced axolemmal resealing in cut guinea pig spinal cord nerves). In the most detailed transection studies, subcutaneous DMSO (tapering over 10 days) reduced secondary cavitation, preserved viable neurons, and produced a softened, well-vascularized scar containing numerous myelinated and unmyelinated axons. Treated animals showed coordinated hindlimb movements beginning around 70-80 days post-lesion, while untreated controls remained essentially permanently paraplegic. Electron microscopy confirmed ongoing Schwann cell-wrapped axonal regrowth at 90-100 days.1,2
When the blood supply to the spinal cord was experimentally interrupted DMSO consistently prevented the resulting spinal paralysis (similar to how DMSO protects from strokes). In the most definitive study, DMSO perfused into an occluded aortic segment in dogs resulted in 11 of 12 animals achieving complete hindlimb recovery versus only 1 of 12 controls, with electron microscopy confirming preserved myelin, axonal integrity, and minimal inflammation. In another canine model, DMSO reduced postoperative motor dysfunction from 7/8 in controls to 2/8. DMSO also prolonged the ischemic tolerance of the spinal cord in rabbits1,2,3,4 and rats, and in numerous separate rabbit ischemia-reperfusion studies, DMSO reduced lipid peroxidation, myeloperoxidase, and peroxynitrite markers while significantly improving neurological function and preventing microscopic tissue damage.1,2,3 Additionally, a selective COX-2 inhibitor in DMSO dose-dependently prolonged the time to permanent paraplegia in rabbits with reversible spinal cord ischemia.
Note: many animal studies are exceedingly cruel and not something I support; however, as they have been done, I felt it was important to share the knowledge they provided so it would not be necessary to repeat them.
A revealing SCI Study
Note: I believe a key reason why many successful preclinical studies fail to provide results in patients is that DMSO is no longer being used as the vehicle (both because of its independent effects and because it potentiates other agents).
For example, in an RCT dog trial of naturally occurring acute spinal cord injuries (primarily from intervertebral disc herniations), an MMP inhibitor (dissolved in DMSO) within 48 hours of injury, improved their mean motor score from 2 to 5. However, when DMSO alone was compared to saline, the exact same benefit occurred, leading the authors to attribute the improved neurological outcomes to DMSO’s wide range of neuroprotective effects (which I detailed here). Likewise, in another study, DMSO provided greater spinal tissue protection than the tested agent (curcumin⬖).
Note: numerous studies have found DMSO improved somatosensory-evoked potentials and that their presence correlates with an improved prognosis and eventual full recovery. Likewise, a 2025 bioinformatics analysis of subacute spinal cord injury identified DMSO as one of only three “promising candidates for modulating inflammation, reducing glial scarring, and promoting axonal repair” out of approximately 17,000 compounds screened, and in isolated rat spinal cord tissue, a medium containing DMSO produced the maximum reduction in lipid peroxidation products, greater than antioxidants alone or any other combination tested.1 A detailed review attributed DMSO’s benefits to its antioxidant and free-radical scavenging properties counteracting the rapid membrane lipid peroxidation and eicosanoid-mediated vasoconstriction that drive secondary ischemic damage.
Safety Data
Note: one early SCI study found DMSO did not reduce gray matter necrosis at one hour post-trauma in dogs (though it increased cytochrome oxidase activity in non-traumatized tissue), two others also found no improvement,1,2 one rabbit study using a low intraperitoneal dose showed only modest MDA reduction. These less favorable findings likely reflect differences in timing, dose, route, and injury severity, consistent with the well-established finding that the best responses are seen when DMSO is used shortly after the injury and higher doses are given.
Veterinary Clinical Use
The response of naturally injured animals to DMSO further supports its clinical utility. In the most dramatic case, an Italian veterinarian described a dog hit by a car that presented with Schiff-Sherrington syndrome (severe spinal cord damage with rigid forelimbs and complete posterior paresis [partial paralysis]). After standard therapy with steroids and glycerol failed over 7 days, he administered IV DMSO. “Ten hours later, the owners told me that the dog stood up and urinated by itself for the first time.” A 19-lb Dachshund with acute posterior paralysis, loss of deep pain sensation, and bladder paresis that had not responded to 14 days of high-dose dexamethasone received a single dose of IV DMSO; by the next morning she was walking, and within one week appeared almost normal. A young dog in Colombia with a T11 vertebral fracture and paraparesis received DMSO and meloxicam alongside physiotherapy, showing intent to use her hind limbs after one week and regaining full hindquarter mobility within weeks.1 A comatose toy poodle with a cervical vertebral fracture received IV DMSO alongside dexamethasone; by day 2 the pupillary light reflex returned, by day 3 consciousness was regained, by day 14 voluntary walking resumed, and at 8 months gait and behavior were nearly normal.
In horses with cervical vertebral fractures, IV DMSO (typically as a solution in Ringer’s lactate given for 7 days) is used as standard treatment, contributing to partial or full neurological recovery. One detailed case series documented an 8-year-old warmblood gelding who sustained three separate cervical fractures over several years and returned to light work between episodes despite progressive degenerative changes, and a 2.5-year-old Friesian stallion with acute C2 fracture similarly improved from neurological score 2.5-3/5 to 1.5/5 over 12 months. Additional equine cases document DMSO contributing to recovery from cervical vertebral arthrosis,1 lathyrism-induced neurological dysfunction, and cervical osteomyelitis.
In downer camelids (llamas and alpacas that can’t stand), IV DMSO was recommended to reduce secondary neurological damage. DMSO is similarly recommended alongside furosemide and mannitol for recumbent foals with spinal cord trauma, and has been administered alongside NSAIDs and corticosteroids for cervical extradural spinal hematoma in horses. In a 2-day-old foal with perinatal asphyxia presenting with seizures, cerebral edema, and acute renal failure, IV DMSO contributed to marked resolution of cerebral edema and complete neurological recovery by day 12. Finally, veterinarian Jack Metcalf found horses developmentally disabled at birth (to the point they can’t nurse), once given IV DMSO three times daily, regained the ability to nurse and had accelerated overall development.
Additionally, multiple readers reported veterinary DMSO applications for spinal and nerve conditions: a horse with hock arthritis, torn suspensory ligaments, lumbar soreness, and frostbite-damaged ears showed improvement across all conditions within 10 days of topical DMSO (including normalized stride, improved backing, deeper breathing from 28 to 12-13 breaths/minute, and return of warmth to chronically cold ears),1 a dog with hip dysplasia and a damaged T2 disc became approximately 20% more comfortable after its meloxicam was compounded with DMSO,1 a veterinarian reported treating a dog’s spine with DMSO and finding the dog “totally recovered” after three years with no repeat treatment needed,1 and multiple readers noted their veterinarians had used DMSO for decades for equine and canine orthopedic and neurological conditions.1,2
Additional Reader Reports
A dog paralyzed by Ehrlichia (a tick-borne disease) was recommended for euthanasia, but daily undiluted DMSO spray applied to the spine at the point where sensation was lost produced gradual return of sensitivity over six months, and the dog can now walk with difficulty.1 Another reported: “I’m a paraplegic with severe neuropathy. DMSO replaced my nerve medication. It works.”1 Several readers reported dramatic responses from topical DMSO for acute spinal injuries: one was “in pain like a cripple” after a tennis fall and had “almost total relief” within 60 seconds,1 another could not walk after a four-car pileup but had “0 pain” overnight from DMSO applied to the upper, mid, and lower spine,1 and a third with a severe back injury from a fall was walking with assistance within five days of starting topical DMSO three times daily.1
Note: DMSO has also been shown to treat many other complications of spinal cord injuries (e.g., Dr. Jacob found DMSO stabilized retrograde ejaculation in paraplegics, along with reducing bladder infections, bedsores, and improving body temperature control). A Russian patent for activating lost motor functions after spinal cord injury incorporated a DMSO elixir (with aloe,⬖ jasmine,⬖ and propolis⬖ extracts) applied topically to motor points as part of a neurophysiologically controlled rehabilitation protocol. Another reader with a 9-year-old daughter with cerebral palsy (and a shunt for hydrocephalus) shared that topical DMSO helped the cerebral palsy symptoms, and one reader’s story (detailed here) shows how IV DMSO can stabilize even progressive spinal cord conditions over decades that would otherwise be terminal.
Combination Studies in SCI Models
Among the most extensively studied, curcumin⬖ improved motor function (BBB scores), inhibited glial scar formation via NF-κB suppression, and when combined with neural stem cell transplantation, enhanced neuronal migration and reduced inflammation.1,2,3,4,5 Resveratrol⬖ downregulated inflammatory GFAP/STAT3, reduced glial scarring, and improved motor recovery via the SIRT1-AMPK autophagy pathway.1,2 Necrostatin-1 repeatedly improved motor function and neuronal survival by inhibiting necroptosis and preserving mitochondrial ultrastructure.1,2,3,4,5,6 Aspirin activated the Nrf2/NQO1/HO-1 antioxidant pathway while suppressing inflammatory TNF-α, IL-6, and astrocyte activation. Rutin⬖ reduced spinal cord edema and pro-inflammatory cytokines via PI3K/AKT. Estrogen reduced inflammation, edema, myelin loss, and axonal damage while improving motor scores, even when treatment was started in chronic SCI,1,2,3 and separately acting through GPR30 protected spinal motor neurons via PI3K/Akt. Progesterone similarly improved locomotor function and preserved white matter.
Among agents targeting cell death pathways, shikonin inhibited TNFR/RIPK1-mediated necroptosis,1,2,3 deferoxamine and edaravone inhibited ferroptosis, liproxstatin-1 upregulated GPX4, TUDCA⬖ reduced neuronal apoptosis and caspase-12 expression,1,2 a cysteine protease inhibitor prevented neurofilament degradation, and a calpain inhibitor reduced apoptosis, hemorrhage, edema, and vascular thrombi.1,2,3
Rapamycin enhanced autophagy, promoted Schwann cell-mediated remyelination, and improved motor function across multiple studies,1,2 with additional work showing it activated the Wnt/β-catenin pathway and enhanced BDNF.1 MiR-125b promoted neural stem cell proliferation and improved neurological recovery via Smurf1/KLF2/ATF2. Rolipram improved motor scores and elevated SOD in spinal cord ischemia-reperfusion, and separately increased Bcl-2 while decreasing caspase-3 in spinal cord transection.1,2 Aminoguanidine (an iNOS inhibitor) repeatedly improved hind limb motor function and reduced neuronal apoptosis in spinal cord ischemia-reperfusion.1,2
A mitochondrial fission inhibitor protected mitochondrial membrane potential and reduced neuronal apoptosis across multiple studies,1,2,3 while 2,4-dinitrophenol (a mitochondrial uncoupler) preserved white matter. CAPE⬖ reduced apoptosis more effectively than methylprednisolone while preserving near-normal histological architecture. Ginsenoside Rg1⬖ also improved depressive behavior following SCI by reducing hippocampal neuroinflammation via p38 MAPK inhibition. Triptolide⬖ improved motor function and upregulated autophagy comparably to methylprednisolone.1,2,3
Natural compounds showing neuroprotective effects include bergenin⬖ (promoted M1-to-M2 macrophage polarization via PPARγ), baicalin⬖ (M2 polarization via JAK1/STAT6), Salvia miltiorrhiza⬖ (reversed oxidative stress in rabbits), melatonin⬖ (suppressed MMP-9 and preserved myelinated white matter), fisetin⬖ (promoted neuronal axon regeneration), and astaxanthin⬖ (enhanced autophagy). Butylphthalide protected mitochondria and inhibited necroptosis,1 while ferrostatin-1 and matrine⬖ each similarly reduced neurological severity.1 An epoxide hydrolase inhibitor reduced disease severity by suppressing multiple inflammatory pathways and in a separate study promoted remyelination.1,2 Pirfenidone improved locomotor scores by reducing fibrosis, and an aquaporin 4 inhibitor (TGN-020) reduced spinal cord edema and glial scarring.1,2 Jasplakinolide reduced astrocyte swelling through F-actin polymerization. Conversely, TrkB blockade (with K252a) suppressed exercise-induced allodynia without impairing motor recovery, indicating BDNF-TrkB signaling mediates post-SCI pain but not the motor benefits of early rehabilitation.
Additional agents showing neuroprotective effects in SCI models include ebselen (reduced oxidative stress),1 pycnogenol⬖ (mitochondrial membrane potential), EGCG⬖ (reduced gliosis), midostaurin (inflammasome modulation), DHEA (reduced IL-1β and caspase-3), EGFR inhibitors1,2 and U01261,2,3 (both reduced glial scarring and promoted nerve fiber regeneration), a PI3K inhibitor (reduced glial scarring), a PP2A activator (promoted astrocyte migration and MMP-2/9 via p38), tamoxifen (reduced NF-κB and caspase-3), butein⬖1,2 (inhibited NF-κB), a Lipoxin A4 agonist, difumarate salt S-15176 (prevented apoptosis), GSK-3β inhibitors1,2,3,4 (reduced neuronal apoptosis and inflammation), a cAMP derivative1,2 (activated Epac2/Akt), aminoguanidine1,2 (reduced iNOS in spinal ischemia-reperfusion), lutein⬖ (preserved motor neurons), zonisamide-prednisone nanomicelles (promoted axon elongation), a PTEN antagonist (promoted long-distance respiratory axon regeneration), a TGFβR-Smad3 inhibitor (reduced syrinx size in syringomyelia), intracellular sigma peptide (improved locomotor recovery), acetylcorynoline⬖ (reduced microglia via EGFR/MAPK), dexmedetomidine (reduced ER stress), P2Y121 and P2Y21 inhibitors (restored mitochondrial integrity and promoted neuronal differentiation, respectively), SPG302 (enhanced synaptogenesis after cervical hemisection), monastrol with chondroitinase ABC (enhanced axon regeneration through nerve grafts), VEGF (promoted spinal cord neural stem cell proliferation), human umbilical cord MSC exosomes (promoted repair via miR-29b-3p/PTEN), tetramethylpyrazine⬖ (improved motor function and NGF expression), JNK inhibitors1,2 (suppressed autophagic cell death), ceftriaxone (prevented motor neuron death), curcumin⬖ (alleviated lidocaine-induced spinal neurotoxicity), dexmedetomidine (protected against bupivacaine spinal neurotoxicity via p38 MAPK), normobaric oxygen with a MEK1/2 inhibitor (protected against decompression sickness), tacrolimus (reduced demyelination and axonal loss by up to 95% in EAE), and ERK inhibitors (enhanced ischemic postconditioning protection).
Note: PEG (polyethylene glycol) has been used as a fusogen to attempt rapid reconnection of severed axons, and DMSO was specifically noted as an additive known to enhance PEG-induced membrane fusion, with two cases achieving functional action potential conduction through reconnected crayfish axons within 30-60 seconds.
Lastly numerous agents combined with DMSO have also shown therapeutic benefit in experimental autoimmune encephalomyelitis models involving spinal cord inflammation and demyelination, including nordihydroguaiaretic acid,⬖ ginkgolide A,⬖ a mitochondrial division inhibitor, curcumin,⬖ a GSNOR inhibitor, and tanshinone IIa⬖.
Radiation Myelopathy
Arachnoiditis
•In 42 patients with chronic cerebral arachnoiditis, transcerebral “superiontophoresis” with DMSO and hydrocortisone (10 mg) over ten sessions produced a statistically significant increase in the proportion of patients discharged with improvement or considerable improvement compared to conventional treatment controls, with no side effects reported.
Note: ultrasound (phonophoresis) or electrical current (iontophoresis) are two methods used to deliver therapeutic agents through the skin (and in the case of phonophoresis, then direct them to a target site). As DMSO has synergy with these modalities, they are frequently combined in Eastern Europe and Russia (where the less correct term “electrophoresis” is often used).
•For cerebral arachnoiditis, endonasal iontophoresis using vitamin E⬖ dissolved in DMSO (applied via nasal turundas for 20–30 minutes, 10–13 sessions) was conducted alongside pyrogenal-induced fever therapy. In one detailed case of post-influenza convexital cerebral arachnoiditis with optic disc stasis, this protocol produced clinical improvement, complete resolution of optic disc stasis, and no recurrence at nearly 3 years of follow-up — reportedly shortening treatment duration and reducing relapses.
Lastly, DMSO has also been used as an enhancer for Karipain (papaya enzyme) iontophoresis in arachnoiditis treatment.
Note: my knowledge here is quite limited (the only reader who tried this never followed up on their progress). I also suspect DMSO injections closer to the spine (which Jacob used for severe spinal injuries) may help, but I have not yet been able to reach the person who would know if this was tried.
Spasticity
In patients with muscle spasticity from a wide range of causes, DMSO mixed with sodium oxybutyrate (GHB) for iontophoresis, plus topical applications with sodium oxybutyrate and lidocaine) was applied to spastic areas after IV sodium oxybutyrate and therapeutic exercises. Daily procedures over 25 days prolonged muscle relaxation beyond the 2–3 hours achievable with IV sodium oxybutyrate alone, reduced pain, spasticity, and reflex excitability (decreased H-reflex amplitude, elevated current thresholds by 2–2.5 mA), increased voluntary movement volume and strength, and improved gait, with one patient progressing from cane-dependent to independent walking. In post-stroke rehabilitation, endonasal iontophoresis of vitamin E⬖ dissolved in DMSO (alongside electrostimulation of paretic muscles) similarly decreased muscle tone, attributed to gradual restoration of cortical-subcortical relationships and modulation of reticulospinal pathways.
In a patient with right-sided scalenus syndrome (painful muscle spasm with neurovascular compression), DMSO mixed with tolperisone (Mydocalm) was applied as compresses for 1.5–2 hours daily for 10 days; combined with intramuscular Mydocalm and vascular therapy, this led to near-complete regression of the pain and muscle-tonic syndrome, restored radial pulse, and warmed hand within 3 weeks.
In decerebrate cats with chronic spinal hemisection, the 5-HT₁B/₁D agonist zolmitriptan (in DMSO) enhanced intermuscular inhibition and stabilized force responses, supporting serotonergic modulation of spinal force feedback circuits for managing post-SCI spasticity. Additionally, a Russian patent proposed DMSO as a transdermal enhancer for a botox patch targeting spasticity (in Parkinson’s, cerebral palsy, dystonia, and multiple sclerosis), potentially bypassing the existing need for repeated injections.
A reader with vaccine-induced Stiff Person Syndrome reported that topical DMSO was the only treatment that relieved constant muscle spasms (spanning back, calves, feet, and chest) over 22 months of uncontrolled pain: “I have it with me at all times.”1 Another reported topical DMSO allowed them to discontinue a muscle spasm pill they’d taken for years.1 Multiple readers also reported topical DMSO resolving restless leg syndrome, in some cases allowing discontinuation of long-term medications1,2,3,4,5,6,7 (e.g., one had cycled through five prescription medications over 30 years until DMSO, while another found a DMSO roll-on applied during a breakthrough episode replaced a 20-minute middle-of-the-night yoga routine, and another noted DMSO on the legs combined with oral magnesium⬖ addressed both neuropathy and restless legs that had prevented sleep).
Note: in a mare with tetanus, intravenous DMSO (as part of intensive supportive therapy) contributed to gradual resolution of rigidity, dysphagia, and systemic signs over 22 days, with discharge without sequelae (other reports also detail DMSO in tetanus treatment protocols for mares).
Spinal Musculoskeletal Conditions
One reason DMSO works so well here is that topical DMSO is most effective at treating small joints close to the surface (e.g., in the fingers), and the vertebral facet joints on either side of the spine fit this profile. Since chronic facet joint inflammation is thought to underlie a significant amount of spinal pain (hence why harmful steroids are routinely injected into them), DMSO’s anti-inflammatory properties are clearly relevant.
However, I do not believe anti-inflammatory action is the primary reason DMSO excels for back pain. Back pain is notoriously heterogeneous (varied): the same symptom can arise from dozens of different causes, a diagnosed finding on imaging (e.g., arthritis) is often not the actual source, and because the true cause frequently cannot be determined—catch-all painkillers are used instead (which partially mask symptoms but never resolve them and require increasingly toxic escalating doses). This heterogeneity also explains why so many treatments show partial evidence: if 40% of cases share a particular cause, a treatment targeting that cause will appear “effective” in 40% of patients while failing or worsening the rest (e.g., spinal surgery is a particularly costly example of this pattern).
DMSO excels precisely because it has multiple therapeutic mechanisms that each address different subsets of back pain: healing tissue injuries, reducing inflammation, restoring blood flow and fluid drainage (which when impaired can cause pain), normalizing bulging discs, resetting dysfunctional neurological circuits (discussed in the next article), and directly blocking pain transmission.
Beyond this, in my own experience, the most common cause of back and neck pain is tight muscles, which makes it quite tragic to continually see patients undergo elaborate, costly, and harmful treatments for something with a fairly simple cause.
Given this last point, one reason DMSO is particularly effective for spinal pain may be its muscle-relaxing properties: DMSO tends to relax skeletal muscle,1 and topical application produces electromyographic (EMG) evidence of muscle relaxation within 60 minutes.1,2 In laboratory studies, 50% DMSO prevented contraction of frog skeletal muscles,1 while lower concentrations (3–6%) enhanced contraction of cardiac and smooth muscle,1 suggesting DMSO selectively relaxes the voluntary musculature responsible for spasms while preserving or enhancing involuntary muscle function.
Note: one cause of back pain DMSO typically cannot address is structural misalignment. However, while DMSO often cannot correct the misalignment itself, it can counteract the chronic irritation it causes and thereby reduce pain. Additionally, many cases misalignments result from tight muscles (which DMSO addresses), knotted fascia or scar tissue (which DMSO ameliorates) or weak ligaments (which to a much lesser degree DMSO addresses), so in some cases it can fix the misallignment.
DMSO also works synergistically with many other therapies that treat specific subsets of pain, and as this article shows, many modalities have been combined with it. One of these is trigger point therapy, an 80-year-old (insurance-covered) approach (which can be very useful) that identifies hyperirritable myofascial (muscle and fascia) points generating chronic pain and deactivates them to resolve the dysfunctional reflex and promote significant musculoskeletal improvement (notably, many trigger point locations overlap with classical acupuncture points).
In turn, in Russian and Eastern European clinical practice, DMSO is widely used in trigger point and myofascial pain management, typically applied topically and mixed with novocaine, diclofenac, hydrocortisone, or lidocaine in compresses over trigger points and spastic muscles.1,2,3,4,5,6 This approach has been applied across multiple body regions (lumbar, cervical, thoracic, facial, and shoulder musculature)1,2 and contexts, including as preparation for acupressure massage (where a DMSO-novocaine mixture applied for one hour facilitated muscle relaxation and improved subsequent manual therapy outcomes),1 as a pre-traction application (DMSO with novocaine over paravertebral trigger points to prevent spasm exacerbations during spinal traction),1 as a topical adjunct after epidural injection courses,1 and via phonophoresis to deliver hydrocortisone into latent trigger points. DMSO has also been successfully injected directly into trigger points (alongside substances such as lidocaine, procaine, B vitamins, and corticosteroids), a method documented in both human1 and veterinary1 practice, though digital ischemic pressure is generally preferred over DMSO injection for animal patients.
Note: DMSO also treats musculoskeletal injuries and joint pain throughout the body (e.g., many readers and studies report it helps shoulder and SI joint issues). However, these are not covered here as this article’s focus is strictly on the spine.
Back Pain (Dorsalgia)
Earlier controlled studies corroborate these findings: a 1968 trial found that in 38 patients with lumbar and cervical disc herniation, treatment duration in the DMSO group was reduced by approximately half compared to controls,1,2 and another study similarly found DMSO treated the root cause of vertebrogenic lumbar pain.
In a staged rehabilitation program for 320 patients with vertebrogenic pain syndrome, DMSO applied topically on the painful segment (alternating daily with pharmacopuncture for up to 5 days during the acute inpatient phase) reduced pain to 0–2 points on VAS in 89% (versus 73% in controls), with long-term remission maintained in 80% when repeated annually.
A Russian patent for treating lumbar disc herniations described a multi-step protocol concluding with applications of a DMSO-drug mixture (e.g., with procaine, ATP, nicotinic acid) on the gluteal and lumbar regions, with two case reports demonstrating substantial pain reduction and functional improvement over 2–5 weeks;1,2,3,4 a 2019 conference on lumbosacral osteochondrosis listed DMSO applications (often via iontophoresis) as an initial therapy used in conjunction with many of these same interventions. In a veterinary case, a 3-year-old Thoroughbred Arabian stallion with acute lumbago, paralysis of the right foreleg, and extremely elevated muscle values regained limited leg movement after a DMSO infusion. A published account similarly described a man with spinal arthritis who was bedridden more than half the time transforming into “an active, pain-free man in exactly 30 minutes” after a single DMSO application.
Note: I have received so many remarkable spinal DMSO testimonials from grateful readers that it is impossible for me to quote most of the ones I want to here and as such, my goal is to provide an idea of the flavor of them and links to the specific issues DMSO cured so that individuals with them can see what others experienced and reach out to them. My best guess from the well over a thousand pain reports I’ve received is that between 80-90% of people who use DMSO for pain have a noticeable improvement from doing so (which matches what early DMSO researchers observed).
Acute Back Injuries
Chronic Back Pain
A few consistent patterns stood out: pain relief was typically 60–100%, onset ranged from minutes to weeks (with longer-standing conditions taking longer), and many were able to reduce or eliminate NSAIDs,1,2,3,4 opioids,1,2,3,4 or other pain medications. One reader with severe chronic back pain described DMSO as the only substance in their life that “beat the too good to be true rule”1 and a physician with 26 years of practice and chronic lower back pain called it “a game changer,”1
One particularly detailed account described a reader with 30 years of “severe disc degeneration L1-S1” who applied DMSO once to the lower back: “It worked immediately and I haven’t had to use it for my back again. That was about 60+ days ago.”1 Another reader with severe chronic spinal pain soaked their entire back in a DMSO-mineral solution for six hours (far exceeding recommended contact time). “Unbelievably, 7 pitch black lumps rose to the surface and formed eschar scabs which finally came off about 4 weeks later.” After these masses were expelled, “my back felt fantastic and I felt 20 years younger,” though subsequently “it felt like something was moving up and down my spine in the fluid.”1
Post-Surgical Back Pain
One reader with over 50 surgeries and a thoracic spinal cord injury (who was also allergic to opioids) called DMSO “life changing,”1 while another after 23 spinal operations reported a 50% reduction in medications within weeks.1 A reader whose wife had nerve shocks in her toes following a poorly executed spinal fusion found that nightly DMSO application to the spine adjacent to the fusion incision “immediately had less severe and less frequent toe shocks” and she no longer needed to charge her back nerve stimulator.1 Another with hardware in the back from fusion surgery gets “a DMSO back rub every day, and it helps,”1 while a reader with Morvan’s disease following viral encephalitis (who had undergone cervical fusion among multiple surgeries) reported 75% pain reduction and visible inflammation decrease after two weeks of topical DMSO.1
Others with fusions at various levels have also reported reduced pain and improved function.1,2,3,4
Scar Tissue and Adhesions
Note: DMSO has been shown to temporarily relocate talin (which anchors structural fibers to adhesion sites) away from those sites, after which the structures reform normally upon DMSO’s removal,1 providing a potential mechanism for these observations.
Radiculitis and Cervical Osteochondrosis Protocols
Note: radiculopathy is a disorder of the spinal nerve root (radiculitis specifically refers to inflammation of the nerve root and frequently causes shooting, radiating pain). Myelopathy is a disorder of the spinal cord itself.
For cervical osteochondrosis with pronounced neuralgic syndromes, topical applications of a DMSO mixture (with procaine, ascorbic acid, calcium gluconate, and ATP) applied for 40–45 minutes every other day over 20–22 days produced rapid analgesia (pain relief) from the first application and elimination of spontaneous pain by 3–4 procedures in patients with reflex syndromes. Over 2 years, exacerbation frequency dropped and disability days fell approximately 4.7-fold (from 481 to 104 total).
These results were independently corroborated across several additional cervical studies: in 40 patients, DMSO iontophoresis on the cervical spine area (combined with NSAIDs, muscle relaxants, and paravertebral blocks) produced acute pain relief within 3–4 days in 32 patients; DMSO-procaine or DMSO-hydrocortisone combinations were separately recommended for shoulder-hand syndrome and humeroscapular periarthrosis in the acute stage of cervical osteochondrosis syndromes; and DMSO applications with dissolved indomethacin or naproxen were successfully used as an alternative to physiotherapy for radicular pain, headaches, and dizziness. In 40 patients with cervical osteochondrosis complicated by shoulder myofascial pain syndrome, DMSO topical applications during the acute phase alongside physiotherapy and dynamic electroneurostimulation resulted in full pain resolution in 34 cases (85%), with significant improvements in shoulder mobility, well-being, and sleep.
In cervical osteochondrosis with DMSO-mud applications (where DMSO solution on a napkin was followed by a layer of therapeutic mud), clinical improvement occurred in 100% of the DMSO-mud group after only 5–6 procedures versus 50% in the mud-only group after 10 procedures, with marked gains in hand dynamometry (e.g., 20 kg → 53 kg), neck range of motion, and resolution of muscle tenderness.
For lumbosacral conditions, in 63 machine operators with professional lumbosacral radiculopathy, standard inpatient treatment including DMSO-shilajit⬖ iontophoresis (alongside NSAIDs, muscle relaxants, massage, and vitamin B) over 12–14 days reduced pain scores by 50%, resolved pain irradiation into the leg in 45%, and improved paresis in 27% of patients (with osteopathy further improving all outcomes). Phonophoresis of Chondrasil ointment (containing chondroitin sulfate⬖ and DMSO) used alongside the NSAID Revmoxicam in a clinical trial for vertebral radiculopathies enabled significant regression of neurological symptoms. For standard Russian and Ukrainian radiculitis and sciatica treatment, repeated DMSO compresses were recommended, with DMSO mixed with procaine applied as compresses on the lumbosacral area for 2–4 hours as a standard protocol for reducing edema and inflammation around affected nerve roots1,2,3 (touching upon the fact DMSO is a highly effective local diuretic).
Note: back when vaccine injuries were acknowledged within the medical literature, one of the leading theories to explain them was that the inflammation and edema they caused (either around the nerve or within it between individual fibers) compressed nerves, particularly those traversing tight spaces (e.g., at the radial groove or spinal nerve trunks). While I believe vaccine-induced microstrokes are the primary issue, I immediately thought of this model when I saw that DMSO indication mentioned in a recent Ukrainian pharmacotherapy manual,1 particularly since other schools of healing also believe this process creates neurologic dysfunction.
DMSO was also, again, used as a base for microapplications on acupuncture zones and myofascial reflex zones in chronic pain syndromes, following a 1982 protocol aimed at eliminating pain, edema, and inflammation.1,2 For the syndrome of the inferior oblique muscle of the head (causing cervico-occipital pain), DMSO applications combined with procaine blockade and muscle relaxation techniques resulted in full symptom resolution. For lumbar osteochondrosis complicated by L5-S1 disc herniation, iontophoresis with a DMSO-procaine solution (anode with mixture, cathode with pure DMSO, current up to 15 mA for 15 minutes, every other day for 10–12 sessions) was part of a 21-day comprehensive rehabilitation program that improved static/dynamic spinal function, reduced pain, and normalized humoral immunity markers (increased IgG, IgM, IgA levels).
Compresses with DMSO solution mixed with procaine were also recommended for acute-phase pain relief in dorsalgia from disc herniations,1 including one study where it (and other therapies) reduced illness duration and sick leave by 42%.
Sciatica
Several readers experienced rapid and dramatic relief. One whose husband had been out of work for four weeks with severe sciatica started DMSO on a Saturday afternoon, applied it every four hours, and he returned to work on Monday.1 A reader with a year of excruciating sciatica reported it was “cured in 2 weeks of regular use, topically with castor oil,⬖”1 and another’s 79-year-old mother who had been bedridden for three weeks with sciatica was out of bed the day after her first application.1
Many readers with chronic sciatica (lasting months to years) reported 90–95% or greater improvement,1,2,3,4,5,6,7,8,9 often describing DMSO as the first treatment to provide meaningful relief after failing physical therapy, chiropractic care, injections, and medications.1,2,3,4,5 Additional readers reported sciatica improvement from topical DMSO (typically applied to the lower back, buttock, and down the leg),1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46 with several noting that combining DMSO with castor oil,⬖1,2,3,4,5 CBD,⬖1,2 or peppermint oil⬖1,2 enhanced the effect.
Note: DMSO can significantly increase the potency of drugs and one reader who combined DMSO with CBD⬖ stated the combination was far too strong for him.1
Additionally, in a study of subpiriform sciatic neuropathy (55 patients across four clinical variants), DMSO with novocaine was applied topically to the gluteal region, piriformis muscle area, and along the sciatic nerve path on the posterior thigh, as part of a differentiated multimodal protocol (including piriformis blocks, muscle relaxation techniques, muscle relaxants, magnetolaser therapy, and other therapies). Compared to 47 patients receiving standard therapy, the DMSO-containing protocol produced superior pain reduction on VAS (e.g., 71.4 to 20.2 vs. 36.2), greater muscle strength recovery, decreased piriformis tension, paresthesia resolution, and improved EMG parameters.
Neck Pain and Stiffness
Neck mobility improvements were particularly striking. One reader’s neck rotation “increased 30 degrees each way in the first week,” causing them to almost cry while driving upon realizing the change.1 After an electric scooter crash producing a severe trapezius/whiplash injury, another reader endured two weeks of excruciating pain and only two hours of sleep per night despite multiple treatments until a morning application of oral and topical DMSO eliminated the pain within 15 minutes1 (similar significant scooter injuries in other readers also resolved, including one 20 years after the original accident1,2 as did other whiplash injuries1,2).
Additional readers reported relief from chronic neck pain,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42 with several noting improved sleep1,2 and reduced medication use.1
Note: several readers who applied DMSO to the neck for pain incidentally discovered improvement in tinnitus,1,2,3 consistent with the cervical nerve/auditory nerve proximity and DMSO improving circulation and nerve function (e.g., one with tinnitus that had “gone off the scale” found it “receded into a different league” within four days of spraying DMSO inside the ear and on the side and back of the neck1). Based on the feedback I’ve received, DMSO alone seems to be about 50/50 in improving or treating tinnitus, which I believe is in part due to tinnitus having many different causes (which vary in their responsiveness to DMSO) and how DMSO is being applied.
A reader with post-traumatic brain injury, cervical instability, and a CSF leak reported that even small doses of oral DMSO lowered intracranial pressure and produced “less fluid retention during the day so less urination at night (massive improvement), better long-sighted eyesight, and improved bowel function,” noting: “I thought I was a certain case headed for dementia, now I have hope.”1 Another reader with a brain, head, and neck injury with CSF leak reported DMSO “transformed my many symptoms.”1
Cervical Disc and Vertebral Conditions
Additional reports of cervical condition improvements include cervical spondylitis or spondylosis,1,2,3,4,5,6,7,8,9 cervical arthritis,1,2 and post-neck-surgery pain.1,2,3,4,5,6
Disc Herniation Enzyme Iontophoresis
One of the most extensively documented applications of DMSO in spinal medicine involves its use as a penetration enhancer for Karipain (Karipazim), a proteolytic enzyme preparation derived from papaya latex containing papain,⬖ chymopapain, proteinase, and lysozyme. In a standardized protocol used across dozens of Russian clinical centers, DMSO added Karipain (dissolved physiological saline), is applied via positive-pole iontophoresis 1-2 times a day for a few months.
In well over a dozen studies, this protocol has been reported to reduce hernia size by 2–7 mm (and volume by up to 52%) on MRI in 75–98% of patients, avoid surgery in approximately 45%, and produce significant improvements across pain and functional measures: McGill Pain Questionnaire index decreasing by 54–72%, Oswestry disability by 33–54%, Roland-Morris by 58–76%, VAS pain scales by 29–66%, LANSS neuropathic pain scores by 44%, Zung anxiety by 50–60%, and EuroQol-5D/SF-36 quality of life by 10–56%. Additional documented benefits include normalized regional hemodynamics (13% venous outflow increase, 29% venous tone decrease), restored motor unit function on electroneuromyography, Lasegue symptom reduction by 61%, improved segmental spinal motion, reduced muscle tone indices, and pain beginning to improve after two days of treatment.1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32
In the largest individual studies, 221 patients with cervical and lumbar disc herniations showed significant reduction in anterior-posterior hernia dimensions on spiral CT in 98.2% after two courses of 20 iontophoresis procedures; in 80 patients with lumbosacral disc herniations, acupuncture followed by 8 courses of DMSO Karipazim iontophoresis caused 75% to show hernia reduction of 2–5 mm on imaging (with prolonged remissions and reduced relapses); and in 54 patients, the addition of DMSO Karipazim iontophoresis to magnetotherapy and Trabert currents showed higher rehabilitation efficacy than the same protocol without enzyme treatment. In two studies of patients with degenerative lumbar spinal canal stenosis (165 and 110 patients respectively), caripapain iontophoresis with DMSO was part of a multimodal conservative regimen; overall outcomes per MacNab scale were excellent or good in 55–84.5% of patients.1,2,3
Morphological studies demonstrated that papain administered via DMSO-enhanced methods had positive therapeutic effects on intervertebral discs,1 and enzyme therapy combined with DMSO-enhanced diadynamophoresis was used in over 8,500 patients across Armenian medical establishments.1,2
Note: in cases where iontophoresis was contraindicated, phonophoresis of Karipain mixed with indomethacin ointment was used as an alternative, with DMSO included to enhance penetration.1,2 A newer formulation1 (Karipain Plus, containing added collagenase and bromelain⬖) showed 15–18% higher efficacy than prior papain preparations, and some centers also used ultraphonophoresis of DMSO with lidase (hyaluronidase) as an alternative enzyme delivery method, contributing to reduced pain, improved spinal mobility, and decreased recurrence frequency.1 One study found that phonophoresis of caripazim gel (eliminating the need for DMSO as penetration enhancer) combined with DAVID diagnostic-rehabilitation trainers produced faster pain reduction and better functional restoration than the standard iontophoresis protocol.1 Additionally, a patent for treating inflammatory-degenerative spinal diseases referenced DMSO as a universal solvent for drugs not soluble in water or alcohol for iontophoresis.
Spinal Stenosis and Spondylolisthesis
One with “severe spinal stenosis and a slipped disk” who was not a candidate for surgery and had no relief from pain injections described DMSO as giving them “my life back.”1 Another with stenosis and spondylolisthesis who had discontinued opioids after a decade found topical DMSO “kept me moving” with rare need for NSAIDs.1 A 75-year-old with grade 1 spondylolisthesis and severe spinal stenosis at L4-L5 reported DMSO “reduces, even removes the pain for a few hours” and combined with other therapies made them “noticeably more functional,”1 while another with 20% forward slippage of L4 over L5 found DMSO “reduced my perceptions of pain considerably”1 (and noted an unexpected side effect of transient erections from larger doses, which they attributed to improved pelvic blood flow—something numerous other readers here have also reported alongside prostate improvements). A reader with grade 3 spondylolisthesis at L5-S1 (with bulging discs, nerve compression, and stenosis at levels above, making fusion inadvisable) who had discontinued epidural steroids after they damaged bone density reported DMSO was “the only thing that works,” producing entirely pain-free days after years of unrelenting chronic pain.1 Others with foraminal stenosis,1 stenoses at various levels1,2 and spondylolisthesis at various levels1,2 also reported pain relief. One reader with a similar L4-over-L5 slippage (triggered by a decades-old motorcycle injury) causing six years of daily pain found topical DMSO largely eliminated his back pain.1
Disc Herniation Reports
Other readers with confirmed disc herniations reported similar patterns: pain elimination within days to weeks,1,2,3,4,5,6,7,8,9,10,11,12 reduced need for epidural injections,1 healing slipped disc with castor oil,1 and functional recovery sufficient to return to work and normal activities.1,2,3,4
Readers with degenerative disc disease similarly reported significant relief,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25 with several noting DMSO was the first treatment to provide meaningful improvement after years of failed therapies, and one reader whose wife’s 50-year-old disc injury (sky diving accident) had been considered untreatable finding that topical DMSO (combined with other therapies), to her doctor’s astonishment, appeared to be healing the disc.1
Intradiscal Injection Therapy
In rat models of nucleus pulposus-induced inflammatory radicular pain, epidural osthole⬖ repeatedly improved mechanical and thermal pain thresholds while reducing inflammatory mediators through multiple pathways (CGRPR1, p38/IL-18, Wnt3a/β-catenin, and CXCL1/CXCR2) in the spinal dorsal horn and dorsal root ganglia.1,2,3,4,5 A p38 MAPK inhibitor delivered epidurally similarly improved mechanical thresholds and reduced phosphorylated p38 in the same model. In a spine fusion study, Oxy133 dissolved in DMSO produced solid fusions with bone densities comparable to BMP2 while significantly reducing adipocyte formation, suggesting potential as an alternative to rhBMP2.
Aspirin Ultraphonophoresis with DMSO
DMSO Formulations
A patented DMSO gel formulation demonstrated stable anti-inflammatory efficacy comparable to standard DMSO ointments in animal testing (reducing kaolin-induced paw edema by approximately 63-74% at 5 hours versus 108% in controls), with high stability (no separation over 180 days at room temperature), convenient non-greasy application, and no toxicity or irritation. A comprehensive Russian review recommended DMSO gel for complex therapy of rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, arthropathies, radiculitis, neuralgia, trauma, and nodular erythema.1,2
Ankylosing Spondylitis
Multiple readers with ankylosing spondylitis reported dramatic improvements from DMSO. Two readers with 23+ year histories of AS (one with 29 fractures from prescription drug complications) reported being off all medications and thriving, with one no longer needing daily DMSO.1,2,3 A reader who started topical DMSO on their knees for AS found that within an hour “I could feel a difference” and could walk stairs normally for the first time in years; after two months, their CRP inflammatory marker dropped from a chronic 9–12 to 3 (near remission levels), with DMSO being the only change made.1 One reader reported “literally ZERO lumbar pain” after one week.1 Others with AS or autoimmune spondylitis reported significant pain and inflammation reduction.1,2
Additional Spinal MSK Protocols
•DMSO has been used across several protocols targeting pathological calcium deposits. DMSO was included in a decalcifying solution (with zinc sulfate,⬖ potassium iodide,⬖ and magnesium sulfate⬖) applied as compresses or via ionophoresis to spine and joints with heterotopic ossification, resulting in reduced pain, improved mobility, and symptom resolution lasting months. In an anecdotal case report, topical DMSO mixed with pure ascorbic acid⬖ powder (applied as a thin paste) reduced spinal stenosis symptoms caused by solid calcium deposits by approximately 80% over six months of intermittent treatment, with the same preparation rapidly resolving symptomatic calcium deposits at other anatomical sites1,2 Likewise, a reader’s husband had a calcium deposit in his shoulder preventing all arm movement with extreme pain: “Within a minute he could move his arm and the pain went away for hours.”1
•For severe lumbar osteochondrosis with motor disorders and pelvic organ dysfunction, transdermal applications of proserin (an acetylcholinesterase inhibitor) in DMSO applied over affected spinal cord segments for 6 hours daily over 10 days improved microcirculation and stimulated synaptic conductance. For postmenopausal osteoporosis with vertebral compression fractures, laserophoresis of a hyaluronic acid⬖-DMSO gel resulted in 68% pain reduction (VAS) and improved mobility in 29 elderly patients. For pain in vertebral fractures complicating systemic osteoporosis, cold compress applications of DMSO mixed with procaine, diphenhydramine, vitamin B12,⬖ and diclofenac were recommended.
•In disc degeneration, atractylenolide I⬖ (in DMSO) inhibited JAK2/STAT3 pathway activation and reduced apoptosis in human nucleus pulposus cells. In humeroscapular periarthrosis, DMSO applications were used alongside glucocorticoid blocks in 91 patients, though standard therapy achieved lasting relief in only 52.7%, with superior outcomes from added phonophoresis of Karipazim mixed with chondroxide and indomethacin ointments.
•For surgery of lumbar scoliosis (with associated spinal stenosis), phonophoresis with hydrocortisone, naclofen, and lidocaine combined with DMSO contributed to pain improvement and neurological deficit regression in 95% of patients. Readers with scoliosis also reported meaningful pain relief from topical DMSO: one with severe scoliosis (50/50 degree curves) found that DMSO with castor oil⬖ eliminated most pain “in 5 seconds,”1 another who had been on pain medication for 15 years and unable to sit without pain “was able to sit without pain for the first time in 15 years,”1 and a 78-year-old family physician with severe thoracolumbar kyphoscoliosis who had declined extensive surgery and found Tramadol ineffective reported that daily oral and topical DMSO made him more active than he had been 40 years earlier (walking 45 minutes daily and lifting weights twice weekly).1 Others reported reduced pain and improved daily function.1,2,3,4,5
•In a novel approach to spinal instability, artificial fibromatization of interspinous ligaments was performed using electrocoagulation followed by a dressing with a DMSO solution, as a minimally invasive prophylaxis against “spinal cord syndrome” in the postoperative period. For ibuprofen-DMSO ionophoresis along the spine in 37 children with active rheumatism, preliminary data indicated the method was promising and superior to existing approaches.
•At a Russian military sanatorium treating victims of terrorist attacks and other emergencies, a DMSO solution was among the most frequently used agents for neurological patients (primarily dorsopathies, 66.3%, and cerebrovascular diseases, 35.6%), administered as part of standardized 21-day iontophoresis rehabilitation courses. DMSO applications were also recommended for vertebrogenic pain syndromes in children, and successfully utilized in conjunction with procaine in a study of 105 children (aged 5-18) with headaches and cervical spine disorders.1,2,3
•DMSO mixed with procaine was used for topical treatment prior to spinal traction in lumbar osteochondrosis. In one clinical study of patients with compressive radiculopathies, hourly DMSO-procaine compresses applied to the pelvic-gluteal area before traction reduced treatment duration by 3–4 days, eliminated vertebral pain syndrome in as few as 1–5 sessions, and achieved stable remission lasting at least 1 year; a separate literature review independently recommended the same protocol, and another review cited DMSO with procaine as an effective treatment for back pain.
•Additionally, DMSO is included in the Dolobene gel formulation (DMSO-heparin-dexpanthenol), which appears in European and Russian clinical practice as a topical ointment for spinal pain. A Czech physiotherapy textbook and German review listed Dolobene gel among recommended ointments for muscle contractures and spasms in acute vertebrogenic disease, in 36 patients it was incorporated into a rehabilitation protocol for shoulder periarthritic syndrome (targeting both the cervical and thoracic spine), and a Russian patent prescribed it as a topical adjunct for residual trigger points after epidural injections for lumbar radicular pain.
•An “Espol” ointment containing combined with capsicum⬖ extract and coriander essential oil⬖ was formulated for neuralgias, radiculitis, and myositis. DMSO with procaine was also recommended as preparation for acupressure massage in muscle-tonic and myofascial syndromes. A clay-based balm (Kavalgin) incorporating DMSO as a penetration enhancer alongside propolis⬖ and laurel essential oil⬖ was patented for treating neuritis, neuralgia, osteochondrosis, and sciatica.
•Lastly, national Russian clinical guidelines (e.g., ATOR 2014 for spinal osteochondrosis) recommended DMSO for use in diadynamic therapy ionophoresis as a topical analgesic/anti-inflammatory agent following decompression lumbar spine surgery. DMSO applications are a standard component listed in clinical guidelines and treatment protocols for back pain across the Russian, Ukrainian, and Uzbek medical literature1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22
Sixty Years of Preventable Suffering
Veterinarians have been using IV DMSO for paralyzed animals for over four decades, with textbooks from the 1980s already listing standardized protocols, yet a human patient with a spinal cord injury is still told nothing can be done (and likewise to quote one reader, after DMSO use allowed them to avoid the back fusion their surgeon had recommended reported the surgeon had “zero curiosity” when told what had worked1).
Every year, tens of thousands of people are consigned to permanent paralysis, wheelchair dependence, loss of bladder and bowel control, chronic pain, bedsores, and drastically shortened lifespans, to say nothing of the toll this takes on their families and the despair that drives the much higher suicide rates seen in this population. That a therapy which routinely gets paralyzed dogs and horses back on their feet has never been seriously tested in human spinal cord injuries, not because it failed, but because the FDA prevented it from ever reaching human trials, is one of the more unconscionable failures of modern medicine.
Note: this indifference extends even to individual success stories: one reader whose
Beyond acute injuries, millions more are trapped on disability by chronic spinal conditions, caught in a system that provides just enough to survive but strips away autonomy, purpose, and hope. Having evaluated numerous disability claims, I cannot begin to describe how frustrating it was to see how many people came through whose lives could have been easily restored with DMSO, to say nothing of the enormous social and economic costs their widespread but unnecessary disability entails.
Russian and Eastern European clinicians have similarly accumulated decades of clinical experience using DMSO for disc herniations, radiculopathies, and osteochondrosis (often via iontophoresis or in combination with enzyme therapy), yet these protocols remain virtually unknown in Western medicine. Fortunately hundreds of readers with chronic back pain, sciatica, failed spinal surgeries, and spinal stenosis have independently discovered that an inexpensive, readily available substance transformed conditions they had suffered with for years or decades.
I consider it a testament to how tightly information is controlled that almost no one in our culture knows about the simple solution DMSO provides, while simultaneously feel profoundly grateful we have at last reached an era where long-hidden truths like this can at last be revealed and I thank each of you for the support which has made it possible to finally get messages like these out.
In the section that follows, I will provide:
•Practical guidance on sourcing DMSO (including how to obtain sterile IV DMSO from compounding pharmacies at a fraction of current prices),
•Detailed dosing protocols for topical, oral, and intravenous use
•The specific clinical spinal dosing protocols summarized from the Russian and Eastern European studies above (for back pain, trigger points, cervical radiculopathy, sciatica, disc herniation enzyme iontophoresis, and more).
•Treatment approaches for neuropathies and neuropathic pain (which will be the focus of the next part of this series), spinal cord injuries, spasticity, arachnoiditis, Parkinson’s, Alzheimer’s, cognitive impairment, chronic stress, and other neurological conditions discussed in this series (e.g., developmental delay, fatigue, brain fog, psychiatric disorders, Down syndrome, or anesthesia toxicity).
Sourcing DMSO:
Note: unless you feel confident in diluting them correctly for topical (skin) applications, opt for the 70% dilution, as that concentration typically works for most people.
•The DMSO Store (e.g., this gel or this liquid—which can also be bought directly from www.DMSOStore.com)—which is 99.995% pure (and hence often the most popular for internal applications).
•Jacob Lab (e.g., this gel or this liquid)—which is 99.98% pure.
•Nature’s Gift (e.g., this gel or this liquid)—which is 99.9% pure.
Note: in some cases, individuals have reported issues with DMSO they bought from Amazon (including for the above brands), but in most cases, there were no issues with Amazon products.
When buying liquid DMSO, I believe it should always be sold in a glass container unless the plastic container is DMSO resistant (which many are not—hence why I only recommended buying glass bottles) and likewise have a DMSO resistant cap. If you buy gel, it’s okay if it’s sold in plastic.
Note: many people have used liquid DMSO from plastic containers without issue, but I have personally always avoided doing so because glass DMSO has always been affordable and readily available so less thinking is involved to ensure it’s sold in a DMSO resistant plastic.
Of the currently existing options, I believe the best choice is to either:
•Buy DMSO directly from the DMSO store (DMSOstore.com).
Note: the website DMSO.store is for a completely different company.
•Buy it directly from Jacob Lab (which is run by Stanley Jacob’s son who is very dedicated to continuing his father’s work).
Note: ideally, DMSO should be stored in amber glass bottles (to prevent sunlight from breaking it down into DMS), but I do not currently know of any supplier offering this who I’ve also verified has high quality DMSO and DMSO resistant seals at the tops of the bottles).
Sourcing IV DMSO
Because of this, I looked extensively into the supply chain over the last year and a half and discovered:
•The only company approved (sterile) to make sterile DMSO in the United States is Gaylord Chemical (which sells it as PROCIPIENT). Procipient (100% DMSO) can be bought online (e.g., Fisher chemical sells 1000ml for 1,225.00 and drops the price to 693.00 if you buy 6).
•A few companies (including the one we used) sell pure DMSO (I believe is sourced from Procipient) to use as a cryoperservative. Like RIMSO-50, these all say “not for injection” on the bottle (despite the stem cells which are preserved in them subsequently being injected). To the best of my knowledge, this label exists due to there being no FDA approved IV DMSO application, but at the same time, some of the sterile preparations (e.g., on Origen’s website) have additives besides DMSO (e.g., dextran) in them.
•Your options hence are to purchase DMSO either from one of the sources in the previous bullet points (either directly from the company or a medical supplier—many of whom carry sterile DMSO), or from a compounding pharmacy. Since I published the original article in Sept 2024, while standard sources have gotten significantly more expensive, compounding pharmacies have begun offering DMSO, and as it’s quite cheap and easy to prepare, many offer it at much cheaper prices close to what we used to pay for DMSO. For this reason, I would strongly advise reaching out to compounding pharmacies until you find one that offers it. Likewise, if you are a patient, there are now a few American clinics publicly offering IV DMSO (which can be found online), more that do not advertise it, and likely many doctors who will be willing to offer it, especially if you do the legwork of finding a compounding pharmacy which will ship it to your state.
•The only permitted way to produce sterile DMSO is to run it through a sterile (DMSO resistant) millipore filter. In addition to this being possible for compounding pharmacies and Gaylord chemical to do, I have also spoken to physicians who have done it, and within Germany, a DIY community exists where high purity DMSO is given as infusions. Given the potential risks of IV DMSO, I do not advise doing this unsupervised, but simultaneously, I have not come across any reports of it causing issues, so it might be quite safe.
•One of the major problems with IV DMSO (or injected DMSO, which can often be quite helpful, such as at home for strokes or certain spinal issues), is that once DMSO is over 15%, it will leach materials from plastics. For this reason, it is advised to either use DMSO resistant IV tubing, use a DMSO resistant syringe and needle (which quickly dilutes DMSO to under 15% once it is injected into a saline bag) or simply buy 15% sterile DMSO. In the first two cases, standard IV plastics will be leached by DMSO, while the DMSO resistant options are either Polyolefins (Polyethylene or Polypropylene), ethylene vinyl acetate or Polytetrafluoroethylene. That said, I am still not completely sure about this topic, as while the German community is adamant leaching occurs above 15%, and I’ve seen cases where it seemed to be happening with 50% DMSO, other data sources say it only becomes an issue over 80%. Because of this, it is probably fine to quickly draw up and expel IV DMSO with a standard syringe into a saline bag, but I try to avoid any potential issues so I use a more complex setup to bypass this issue.
DMSO dosing:
However, most of it boils down to the following:
•If you use too high a dose, you risk having a bad reaction (which dozens of people have now told me made them not want to use DMSO anymore), whereas if you use too low a dose, the effect will be much less than desired (which may also lead to them abandoning DMSO). In turn, I’ve had many people here who:
- Applied 100% DMSO topically and had trouble believing anyone couldn’t tolerate that.
- Applied 70% DMSO topically, had a bit of irritation, but thought it was manageable [this is the most common optimal topical dose].
- Applied 30% topically and felt it was too strong.
Similarly with oral dosing, I’ve had people who:
- Thought 1 teaspoon in a glass of water [the most common optimal oral dose] was decent, but quickly took more for a greater effect.
- Found that a few drops was the optimal dose for them (and greatly benefitted), whereas 1 teaspoon while initially good, ended up feeling like it was too much for them and caused their sensitive system to react.
Because of this, you essentially have two options, and have to decide which is right for you:
•Be patient and start with a low dose, then build up progressively.
•Start with a strong dose, and agree not to hold it against me or DMSO if you don’t tolerate it.
Note: in some cases it can take a while (a few weeks, and sometimes a few months) for DMSO to significantly improve an issue like chronic pain, but normally the response is much faster at the correct dose.
In the previous articles, I’ve advocated for the former. Still, many understandably started with a high dose as they did not want to wait for the results, and a few of them then shared they’d had a skin reaction that made them hesitant to continue using DMSO.
Similarly, when using DMSO, there are two common routes of administration: oral and topical. Orally, it is much stronger, but likewise, the GI tract is more sensitive to higher concentrations of DMSO. For this reason, I typically suggest starting with topical DMSO before doing oral DMSO. However, for more systemic issues (e.g., joint pain throughout the body or low energy), oral use is often necessary (and in many cases, works well when combined with topical DMSO).
Likewise, there is a minimal risk (1 in 2000) of an allergic reaction, so it’s generally advised to begin by patch testing DMSO on the skin before taking it orally.
So, What is Patch Testing?
Patch testing is a method used to determine how a product reacts when applied. It’s a smart way to test a small area first before applying the product to larger areas, helping identify any adverse reactions.
How to Patch Test:
•Select a Small Area: Choose a discreet spot.
•Apply a Tiny Amount: Use a small quantity of the product.
•Wait and Observe: Leave it on for 24 hours unless you notice irritation sooner.
•Proceed if All’s Good: If there’s no reaction, feel confident to use the product as intended!
*If in contact with the skin: some experience itching and tingling sensations and irritation, which are normal. If there are any signs of an allergic reaction (e.g., swelling), wash the area immediately and discontinue use.
That said, for general DMSO use (without going into all the nuances and additional details), I advise the following:
- Start with 30-50% DMSO and see how you tolerate it. If applying to the face, make sure all makeup has been washed off (and ideally that you are only using natural cosmetic products) and use a lower initial concentration (20%).
- If you have no issue, gradually raise it to 70%. Many find 60% suffices for most musculoskeletal issues, while 30% is often needed for sensitive skin.
- Only raise it past 70% if you are certain you are one of those people who are fine with 100% or you are using it for a specific application that can justify a higher concentration (e.g., a collagen contracture, a scar, an internal adhesion, or an acute stroke).
- If you have immediate issues with topical administration (e.g., burning or redness) that you cannot tolerate, wash off with water and try a lower dose. If your skin becomes cracked or dry after repeated use, take a break and hydrate the area with aloe or a natural oil.
- Until you are comfortable with topical applications, avoid oral applications, and only use them if you think you need them (or topical does not work for a reason besides an allergic reaction).
- For oral dosing, start with a teaspoon of 70% or 100% DMSO mixed into a glass of water (you may also want juice, a smoothie or milk to eliminate DMSO’s taste), as a heavily diluted solution is best to start with.
- If you have issues with that, lower the dose to half a teaspoon and then to a quarter teaspoon.
- Otherwise, stay at a teaspoon for at least three days, and then if you think you need a more substantial effect, go to 2 teaspoons.
- More than 4 teaspoons in a glass of water is excessive, and at that point, you are better off dividing the dose throughout the day.
- With both topical and oral DMSO, people generally find that as time goes on, their reactivity to it decreases (so they better tolerate it). Conversely, if it’s used too frequently, particularly for chronic pain, a tolerance can develop, so it’s generally advised to skip 1-2 days a week if it needs to be taken long term.
Note: since DMSO concentrations can be difficult to calculate, one reader made an excellent online calculator that can guide you through how to achieve any target DMSO concentration with the DMSO you have (which can be viewed here).
Regarding concentrations, I generally advise buying 70% DMSO because people rarely react to it (e.g., the DMSO community found this concentration offered the best balance between safety and efficacy). It doesn’t require any significant calculations to dose appropriately (e.g., you can apply it topically as is, or mix it with equal parts purified water to roughly 35%). However, you can also do all of that with 100% DMSO (e.g., dilute it to roughly 50% by mixing with equal parts purified water, or to roughly 33% by mixing with 2 parts purified water). Finally, certain parts of the body, particularly the face, tend to be more sensitive to higher concentrations of DMSO, so you should start at lower strengths in those areas.
If you are applying DMSO to the face (which is more sensitive to DMSO), start at 30% and do not use a higher concentration, as this can cause significant skin irritation. For example, I had one reader who started with a 70% gel on the face and contacted me about a reaction she had (although after the surface layer of skin peeled off, her face underneath looked much younger).
Additionally, a challenge in dosing DMSO is that it weighs slightly more than water (1 mL of DMSO is 1.1004 grams). Since DMSO has a relatively wide range of tolerability, I’ve bypassed that issue by treating it as having the same density as water and suggesting a slightly lower oral dose.
When applying DMSO topically, there are two options. The first is to use a liquid that you directly apply (e.g., I like to use paintbrushes made from natural hairs to dab it on, but sometimes when needed, I just dip my finger in it and then rub it onto the target area, whereas the DMSO field often uses sprays for sensitive skin conditions). The second is to use a gel that is rubbed into the skin.
Note: DMSO will leach many plastics at concentrations above 20%. For this reason, 15% or lower is often advised for situations where it has to come into direct contact with them
I personally prefer the liquids because they’re easier to control the total dose with, more of the substance gets into the body, and liquid DMSO tends to be less irritating. That said, gels hold the advantage of continually releasing DMSO into the body over a prolonged period and are much easier to apply. As a result, the choice you make is largely a matter of personal preference.
Note: as mentioned above, when applying DMSO topically, it is essential first to clean the area where it is being used.
Lastly, since many readers have requested it, this is a general guideline on what doses of DMSO tend to be appropriate for each part of the body:
Internal Use (Oral):
- Starting Dose: 1 teaspoon in an 8 ounce (or greater) glass of water.
- Increase: Up to 3 teaspoons (~15 ml) twice daily for treatment.
- Body Weight-Based: 0.05-0.1 g/kg/day (e.g., 7 g for 70 kg, ~2.5 teaspoons), with higher doses (typically up to 2 g/kg) for emergencies (e.g., heart attack or cancer).
Note: as DMSO has an unpleasant taste, it is frequently consumed with juice and away from meals. Additionally, if higher doses are used (especially over 3 tsp), it is important sufficient water is present to dilute DMSO as higher concentrations (especially above 20%) can irritate mucous membranes.
External Use (Skin):
- Concentrations:
- Legs/Feet: 50–80% (70% typical).
- Arms/Torso/Neck: 40–70% (50% typical).
- Head/Face: 25–35%. (some go up to 50% for the head)
- Wounds: 40–60%.
- Warts/Boils: 75%.
- Sensitive Skin: Start at 30%.
- Application: 2–3 times daily, adjusted based on skin sensitivity and response.
- Precautions: Avoid >15% on surgical stitches to prevent brittleness.
- Ideal routes of application include with natural hair brushes (dabbing creates less irritation than rubbing), with your own (clean) fingers, or with a spray bottle (particularly for open wounds or areas that are otherwise hard to reach on your own body). With spray bottles, glass ones which have been pre-washed with DMSO are ideal.Note: gloves should never be used to apply DMSO to the skin (as very few gloves are DMSO resistant and as such the chemicals in them will be leached into the skin).
Mucous Membranes:
- Mouthwash: 5–15% solution, swish for 2–4 minutes (can go higher if no dental implants).
- Ear/Nose Drops: 15–40% (15% minimizes irritation).
- Other (e.g., oral, rectal, vaginal): around 10% is often recommended due to high tissue permeability.
- Gum issues/inflammations: Use 5–15% mouthwash.
- Aphthous ulcers/cold sores: Dab directly (often with 100% DMSO).
Injections:
- Concentration: 15% for subcutaneous, intraarticular, intraperitoneal.
- Intramuscular/Intravenous: 3-25% in an isotonic solution (we tend to use 3-5%, 7.5% is frequently recommended, most of the published studies, particularly in acute emergencies used higher doses).
Eyes: 3% isotonic solution has the best balance of safety and efficacy (although many go up to 40% or even higher which I feel is a bit too high—20-30% should be the maximum—however the eyelids can tolerate higher doses than the eyes and applications there will also help the eyes).
Nebulized 1% isotonic solution (although some go much higher—e.g., numerous readers have been using 50%).
Note: be sure to clean the nebulizer before nebulizing DMSO.
Lastly, in some cases, particularly for injuries, DMSO is applied by soaking a bandage in it (or a DMSO mixture), placing it on the affected area, and then wrapping it with other bandages to ensure continuous DMSO exposure. In those instances, due to the prolonged exposure lower concentrations can be required, and if so, it is ideal to use a natural material (e.g., cotton).
Note: after prolonged DMSO exposure, DMSO can cause the fingers to wrinkle in a manner similar to being in water for a prolonged period but will recover in a few days.
IV Dosing
We now know that the optimal dose of DMSO in human patients sustaining a severe brain injury is 1 g/kg in a 28% solution mixed with 5% dextrose in water….The minitrial using DMSO to treat intracerebral hemorrhage and ensuing arterial spasm by Mullan et al. indicates that a DMSO bolus or very fast drip at doses of 1 g/kg/8 h in a recommended 28% solution appears as a safe and effective regimen.
Note: every reference I’ve found settles between 1-2g/kg (typically 1-1.5). In one detailed toxicity study, a researcher found giving 3 g/kg of DMSO (diluted to 40%) to rhesus monkeys for 9 days caused no detectable issues for 4 months after treatment. Additionally, in the existing literature, the issue they repeatedly ran into was that when a lower concentration was used (e.g., 10%), it would trigger significant diuresis (urination), and there were a few reported instances of hypernatremia or fluid overload occurring following low concentration DMSO.
These human doses align closely with what veterinarians have used for decades. A 1983 equine textbook recommended 0.9–1.0 g/kg at 30–40% once daily for 3 days then every other day for 3 more for brain and spinal cord injuries in horses (including comatose ones), with an alternative protocol of 1 cc/kg in 1 liter of saline every other day for cervical vertebral lesions. For horses with cervical fractures, the standard treatment is 1 g/kg as a 10% solution in Ringer’s lactate for 7 days. For downer camelids, 1 ml/kg of 99% DMSO diluted to 10% IV is recommended. In dogs, dramatically lower absolute doses have produced remarkable results: 5 ml of IV 90% DMSO reversed Schiff-Sherrington syndrome in a dog hit by a car, a single 6.9 g IV dose had a paralyzed 19-lb Dachshund walking by the next morning, and IV DMSO at 30%, 1 g/kg brought a comatose toy poodle with a cervical fracture from unconsciousness to voluntary walking within 14 days. The only human safety study of IV DMSO for spinal cord injuries (10–40% in seven patients) found no adverse renal effects.
Stanley Jacob (the most knowledgeable person in this field) settled on 10% DMSO in D5W (typical) or saline (occasionally). We tend to use a much lower IV DMSO dose than any of the references I’ve come across (3-5g of 100% DMSO diluted in 100 ml of saline) as we found it worked, but that is in part because we never used it in the acute setting where higher doses are needed (rather it is used for general neurological rehabilitation). Conversely, many people have reached out to me to share success with higher doses. Todd for example used 10ml of 90% DMSO mixed in a 500 ml bag of 0.9% saline infused over an hour once a week as he found higher doses were critical for his improvements. Some of the other dosing regimens I’ve come across are:
- Up to 20-80ml of 25% DMSO given as an IV push 1-3 times a day (for conditions such as arthritis or cancer, Parkinson’s or multiple sclerosis).
- 500 ml of 10-20% DMSO (diluted in saline or 5% dextrose) dripped over 2-3 hours.
- A 50ml bolus of 28% DMSO mixed in 5% dextrose (this was the dose used in the two studies of 10 patients with severe closed head injuries).
- DMSO 560 mg/kg in a 28% solution, FDP 200 mg/kg mixed in 5% dextrose twice (this was the dose used in the 2002 clinical trial of 11 patients with ischemic strokes).
- Daily IV pushes of 3gm of DMSO.
- If over 25ml of DMSO (27.5g) is to be taken at any one time, diluting it in 1000ml (rather than 500ml).
- For non-emergent cases, 1 g/kg, diluted in 500ml of fluid (typically saline or 5% dextrose), sometimes having micronutrients added in, given daily for 5-10 days, followed by a 2 day break, before the treatment is again resumed. Typically, a half dose is given initially to observe the patient’s response.
Note: one important practical consideration with IV DMSO is that at concentrations above 15%, it will leach materials from standard IV plastics. DMSO-resistant options include polyolefins (polyethylene or polypropylene), ethylene vinyl acetate, or polytetrafluoroethylene (PTFE). One workaround is to use a DMSO-resistant syringe to quickly inject concentrated DMSO into a saline bag (where it immediately dilutes below 15%), or simply to use pre-diluted 15% sterile DMSO. This was actually one of the major obstacles to DMSO entering hospital practice in the 1960s–1980s: it would partially dissolve the tubing it went through, and DMSO-resistant IV equipment was challenging to procure.
Given all of this, I believe the dose we use is safe, while the higher doses others use are probably safe, but we can’t say with certainty (e.g., it may be wise for people doing higher IV doses to carry atropine in their clinic for a potential heart slowdown). Conversely, I am also not sure if the higher doses have merit for more complex disease (e.g., ALS) and can provide better results than the (satisfactory) ones we’ve seen with lower doses, but I suspect in many people they can.
Treating Neurological Diseases
For example, many integrative practitioners have found the same measures which help autoimmune disorders (discussed further here), such as sleep, stress reduction, gentle routine exercise (which increases fluid circulation) and sunlight (which through the eyes directly nourishes the central nervous system) and diet are also immensely helpful for neurological disorders.
Many psychiatric and neurodegenerative disorders improve from eliminating food allergens or adopting a ketogenic diet (e.g., I’ve read many stories of profound improvements in psychiatric diseases following the elimination of food allergens, parents of autistic children frequently find removing food allergens to be one of the most effective measures they can take, and both RFK Jr. and Jordan Peterson’s daughter recently brought attention to the immense improvements ketogenic diets can create for psychiatric disorders). Likewise, strong evidence now exists for a ketogenic diet improving drug-resistant epilepsy, growing evidence supports it for Alzheimer’s, Parkinson’s, MS and migraines, and preliminary evidence supports its use in cluster headaches, bipolar disorder, schizophrenia, major depressive disorder, autism spectrum disorder (ASD), traumatic brain injury, strokes and spinal cord injury.
Note: ketogenic diets are thought to work because they provide an alternative fuel source to mitochondria and alleviate the pervasive mitochondrial dysfunction seen in these diseases; I would argue that a root cause of that mitochondrial dysfunction is impaired microcirculation to the brain.
In addition to these general therapies, most functional medicine providers who treat neurological diseases also provide nutritional supplementation, often guided by micronutrient evaluations (e.g., the SpectraCell test excels in this regard), and frequently involving B12 supplementation.
DMSO in turn offers promise here, as it can deliver these therapies, frequently in a manner which bypasses the need for injectable preparations, thereby allowing these regimens to be done affordably at home.
Note: IV therapies are the most potent for treating neurological disorders (especially neurodegenerative ones), while oral administration is the most practical and most commonly utilized option. Topical application is often targeted: over the carotid arteries on the front and side of the neck for conditions affecting the front and middle of the brain (which they predominantly supply), over the vertebral arteries along the back of the neck and base of the skull for conditions affecting the brainstem, cerebellum, and rear of the brain, along the spine for spinal cord involvement, and at the site of any local manifestation (e.g., the leg).
Lastly, for many neurodegenerative diseases (e.g., Parkinson’s, Alzheimer’s and ALS) removing toxic metals from the body like mercury is often extremely important.
Acute Neurological Emergencies
Note: there is also some preliminary data showing IV lidocaine is neuroprotective in strokes, but only if it is given immediately after the stroke starts (making it impractical to ever use in it outside of situations like this).
Spinal Cord Injuries: As the article detailed, the greatest benefit occurs when IV DMSO is given within 90 minutes of injury, with higher doses increasing the speed and likelihood of recovery. However, significant rehabilitation is possible even for injuries years or decades old (e.g., one reader paralyzed for 13 years was walking without braces after three months of oral DMSO at 1 tablespoon in water twice daily). For acute injuries where IV access is unavailable, topical DMSO (75%, three times daily) has produced dramatic results, with one reader walking with assistance within five days of a severe fall. In experimental animal transection models, subcutaneous 50% DMSO (tapering over 10 days) preserved viable neurons and produced coordinated hindlimb movements by 70–80 days, while untreated controls remained permanently paraplegic. A Russian patent for SCI rehabilitation used a 25% DMSO elixir (with aloe,⬖ jasmine,⬖ and propolis⬖ extracts) applied topically to motor points. The IV veterinary protocols detailed in the dosing section above (0.9–1.0 g/kg at 30–40%) apply here as well.
Anesthesia Toxicity: We’ve found vitamin B1⬖ and B12 significantly reduce the cognitive impairment from surgeries. Ideally, they should be given before the surgery (more important) and can also somewhat help if given afterwards. When doing this, we’ve found the best results are obtained from subcutaneous injections (as this promotes better absorption than injection into the muscles) and that formulations of the shots which are not preserved in aluminum should be used.
Neurodegenerative Diseases
Note: while most of the data collected for this protocol showed it worked in Parkinson’s, it also showed promise for multiple sclerosis, migraines, ataxias, Huntington’s disease, and other neurodegenerative diseases. I also suspect oral DMSO with amino acids may help Parkinson’s but I do not yet have enough data to say (and may also greatly potentiate the effectiveness of L-DOPA).
The major challenge with this protocol is that since thiamine⬖ is poorly absorbed, a lot has to be taken (which makes the protocol challenging to follow). As such, it is much easier to do it with injectable B1 (where I would advise subcutaneous injections of preservative-free formulations). DMSO in turn offers key benefits here. First, it eliminates the need for injectable B1, as it can directly transport B1 into the body. Second, as the encephalopathy studies earlier in this article showed, in conditions which responded to B1, DMSO also provided a therapeutic effect, but when combined with thiamine,⬖ produced a greater benefit than thiamine⬖ alone (especially as the condition began to become “irreversible”).
Separate from thiamine,⬖ a variety of other likely useful combinations exist (e.g., the reader I cited above found combining DMSO with sulforaphane⬖ helped him, and as the studies in this article show, research corroborates this has a mechanistic basis). My hope is that some of the studies I’ve provided in this article will provide the initial inspiration to see if any of them, in combination with DMSO, will prove beneficial.
Finally, DMSO alone also shows significant benefit in Parkinson’s. However, due to this being a highly variable disease, I feel it is particularly important to start with a low dose and build up (e.g., the reader here who had the most success with DMSO found 1.2–1.5g/day reliably made him better, whereas doses above 1.5g a day reliably worsened him). That said, we’ve also spoken to numerous people who did not have these dose-limiting issues (including those who benefitted from the much higher doses of IV DMSO).
Lastly, in many cases we find Parkinson’s will improve with neural therapy (injecting lidocaine to reset overactive nerves), most commonly somewhere in the gluteal area for an affected leg or the thoracic spine for an affected arm, allowing patients to regain lost mobility. Due to the effectiveness of that approach we have not experimented with using DMSO in its place, but I feel it is quite possible that applying DMSO to an affected limb all the way back to the sacrum or spine could be quite helpful for these movement disorders, as DMSO too, to a degree, resets the same dysfunctional circuits lidocaine targets.
Alzheimer’s: In addition to standard neurological protocols (or combining DMSO with B1 and B12), the more detailed therapies we have found which also help Alzheimer’s are discussed in this article. Additionally, the German community has found oral galactose⬖ combined with DMSO can be helpful for both Alzheimer’s and Parkinson’s. One physician also found that rubbing DMSO on the scalp followed by photobiomodulation at 40 Hz over all 4 brain areas (10 minutes each) produced excellent results for early Alzheimer’s in ApoE4 carriers.
Developmental Delays, Down Syndrome and Behavioral Issues: The German DMSO community was able to obtain the amino acid⬖ DMSO formulations used in South America to treat these conditions and has since refined them, finding they significantly benefit children who use them. They are discussed in this article.
Psychiatric Disorders and Cognitive Issues
Note: other natural DMSO combinations for fatigue are also covered in this article.
Impaired Cognition and Brain Fog: In addition to B12, some of the most common DMSO combinations used to improve cognition include B-complexes, Ginkgo biloba extract,⬖ amino acids,⬖ GABA,⬖ galactose,⬖ 5-HMF, methylene blue, lithium orotate, melatonin,⬖ glutathione, and NAC (all of which are discussed here). One of the interesting properties of DMSO we have been exploring recently is that it temporarily increases the optical transparency of tissue, thereby “potentiating” light therapies applied over skin with DMSO on it. As red light therapies often help the nervous system (e.g., we find the Hooga lamp to be quite helpful for brain health), this argues for a logical synergy.
Spinal and Peripheral Conditions
Radiation Myelopathy: DMSO (10–15% aqueous solution) applied topically to the zone of radiation-induced spinal cord damage, followed 1–2 hours later by acupuncture, shortened treatment duration from 60 to 30–40 days and produced positive neurological outcomes persisting for at least 6 months.
Arachnoiditis: In 42 patients with chronic cerebral arachnoiditis, transcerebral superiontophoresis with DMSO (50%, 10 mg) and hydrocortisone (10 mg) over 10 sessions significantly improved outcomes compared to controls. For cerebral arachnoiditis, endonasal iontophoresis using 5% vitamin E⬖ dissolved in 50% DMSO (nasal turundas for 20–30 minutes, 10–13 sessions) alongside pyrogenal-induced fever therapy shortened treatment duration and reduced relapses.
Spinal Pain Conditions: The most common approach readers successfully used for degenerative spinal conditions was topical DMSO (50–70%) applied to the affected spinal region 2–3 times daily. In Russian and Eastern European clinical practice, more structured protocols have been extensively documented, which I have summarized below.
Note: the next article in this series will cover peripheral nerve regeneration, neuropathies, neuropathic pain, the deeper cellular mechanisms behind DMSO’s regenerative effects, and practical pain protocols including the ambroxol-DMSO formulation.
Clinical Spinal Dosing Protocols
Trigger point and myofascial pain: The standard Russian protocol uses 25–40% DMSO mixed with novocaine, diclofenac, hydrocortisone, or lidocaine in compresses over trigger points for up to 1.5 hours daily across 10-session courses. DMSO has also been injected directly into trigger points at 0.2–0.25% alongside lidocaine, procaine, B vitamins, and corticosteroids. A 1:1 DMSO-novocaine mixture applied for one hour was used as preparation for acupressure massage, and 33% DMSO with novocaine was applied as hourly compresses on the pelvic-gluteal area before spinal traction, reducing treatment duration by 3–4 days.
Cervical radiculopathy and osteochondrosis: In four studies (64–147 patients each), 33% DMSO with procaine was applied as compresses to painful myotonic points on the neck or shoulder for 1.5–2 hours per session over 10–15 procedures. For neuralgic syndromes, 35% DMSO with procaine, ascorbic acid, calcium gluconate, and ATP was applied for 40–45 minutes every other day over 20–22 days, with disability days falling approximately 4.7-fold. DMSO-mud applications (25% DMSO on a napkin followed by a layer of therapeutic mud) produced improvement in 100% of patients after only 5–6 procedures versus 50% in the mud-only group after 10.
Radiculitis and sciatica: The standard Russian/Ukrainian protocol uses 50% DMSO compresses for 20–30 minutes over 6–12 sessions. For lumbosacral edema, 5 ml DMSO mixed with 15 ml of 1% procaine is applied as compresses on the lumbosacral area for 2–4 hours. For disc herniations specifically, 30–50% DMSO with procaine compresses are recommended for acute-phase pain relief.
Disc herniation enzyme iontophoresis (Karipain): In the most extensively documented protocol, 2–3 drops of DMSO are added to 1 g of Karipain dissolved in 5–10 ml saline, applied via positive-pole iontophoresis (10–15 mA, 10–20 minutes per session, 20–30 procedures per course, 1–3 courses at 30–60 day intervals). This has been reported to reduce hernia size by 2–7 mm on MRI in 75–98% of patients and avoid surgery in approximately 45%. For L5-S1 herniations, a 1:3 DMSO-procaine solution (anode with mixture, cathode with pure DMSO, up to 15 mA, 15 minutes, every other day for 10–12 sessions) was used as part of a 21-day comprehensive rehabilitation program.
Aspirin phonophoresis: 100% DMSO was used to dissolve 5–10% acetylsalicylic acid for ultrasound phonophoresis treating radicular and reflex syndromes of lumbar osteochondrosis, yielding pain relief after 5–6 procedures in 78% of patients.
Lumbosacral iontophoresis: DMSO-shilajit⬖ iontophoresis (alongside NSAIDs, muscle relaxants, massage, and vitamin B) over 12–14 days reduced pain scores by 50% in machine operators with professional radiculopathy. At a Russian military sanatorium, 25% DMSO was administered as part of standardized 21-day iontophoresis rehabilitation courses. Hyaluronic acid⬖-DMSO gel laserophoresis produced 68% pain reduction in postmenopausal osteoporosis with vertebral fractures.
Chondroxide ultraphonophoresis: 5% Chondroxide ointment (containing chondroitin sulfate⬖ and 10% DMSO) applied via ultraphonophoresis for 10 days improved range of motion and significantly decreased pain in cervical osteochondrosis.
Intradiscal injection: In two studies, a mixture of glucosamine,⬖ chondroitin sulfate,⬖ dextrose, and DMSO injected directly into damaged discs improved disability and pain scores approximately 50% at 12-month follow-up.
Additional protocols: For severe lumbar osteochondrosis with motor disorders, proserin in 33% DMSO was applied over spinal segments for 6 hours daily over 10 days. For photodynamic therapy of spinal complications, 0.1–0.5 g photosensitizer in 3 ml of 50% DMSO applied 20 minutes before laser irradiation achieved pain elimination in 70% and overall efficacy in 90% of patients. For pathological calcium deposits, 1% DMSO with zinc sulfate,⬖ potassium iodide,⬖ and magnesium sulfate⬖ was applied as compresses or via ionophoresis. For osteoporotic vertebral fractures, 10% DMSO with procaine, diphenhydramine, vitamin B12,⬖ and diclofenac was applied as cold compresses.
Commercial Spinal Formulations
Other Peripheral Conditions: Many other central nervous system disorders will also respond to DMSO with similar protocols to those detailed in this article. For peripheral conditions (e.g., neuropathies, neuropathic pain, or restless legs), a combination of oral and topical DMSO often works quite well (with topical alone sometimes being sufficient). With topical application, sometimes applying at the affected area is sufficient, but in other cases, you need to trace back to the spinal cord and be sure to apply DMSO along the path of the blood supply (and sometimes the nerve). Overall, the two best topical combinations for peripheral neuropathy appear to be DMSO and castor oil and DMSO and ambroxol (detailed here), the latter of which I believe is more effective. Additionally, combining DMSO with lidocaine or an magnesium chloride can be helpful. Finally, in challenging neuropathies or neuropathic pain, it can be necessary to not just apply DMSO to the area of pain, but also the area that feeds into it (e.g., the applicable region of the spine all the way to the end of the affected limb).
Conclusion
As you can imagine, putting this article together has been an immense amount of work. However, due to how many people it has the potential to help, and my goal to get as much of this material out there as possible during RFK Jr.’s term, I did so. For the first time in my life, I’ve felt like we have a real window to bring the forgotten medical therapies back into common use, and I sincerely thank each of you for your support in making this possible.
