Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Dimethyl sulfoxide (DMSO) has been investigated for its potential in treating nerve damage, primarily due to its anti-inflammatory, antioxidant, and membrane-penetrating properties. Scientific studies, mostly in animal models and limited human trials, suggest that DMSO may reduce nerve inflammation and edema, and possibly improve functional recovery after nerve injury. For example, some research has shown that DMSO administration following peripheral nerve crush injuries in rats can decrease inflammatory damage and support nerve regeneration. Additionally, its ability to scavenge free radicals is considered beneficial in reducing secondary injury after nerve trauma.

However, the clinical evidence in humans is sparse and somewhat inconsistent. While DMSO has been used topically or intravenously in various contexts (including interstitial cystitis and as a vehicle for other drugs), its direct application for nerve damage in routine medical practice is not well established. Few controlled clinical trials exist, and those that have been conducted tend to have small sample sizes or methodological limitations. As a result, most medical guidelines do not recommend DMSO as a primary treatment for nerve damage.

In summary, there is some preclinical scientific evidence supporting DMSO’s potential benefit in nerve injury, but robust clinical validation is lacking. The current evidence base justifies a low to moderate rating (2/5) for its use in this context.
