Dimethyl sulfoxide (DMSO) is a colorless, slightly oily liquid that has been used topically in folk and alternative health practices for decades, primarily for musculoskeletal discomfort. Research suggests that DMSO may have anti-inflammatory and analgesic properties when applied to the skin, with some studies indicating potential benefits for joint pain and soft tissue inflammation. It has also been investigated for bladder and urinary tract health, and in fact a prescription form is FDA-approved for a specific bladder condition called interstitial cystitis. While DMSO is widely available as a topical gel or liquid, it is worth noting that it rapidly penetrates the skin and can carry other substances with it, so the quality and purity of any product matter considerably. The overall body of clinical evidence remains mixed, and further well-designed trials are needed to confirm many of the traditionally attributed benefits.
