As news of its potential medical applications has spread through lay publications, DMSO has gained popularity in the unregulated world of homeopathic remedies and health and nutrition outlets. Radioactive tracer studies of DMSO absorption in humans found that 5 minutes after cutaneous application, DMSO is detectable in the blood; after 1 hour, it is detectable in the bones.12, The free electron pairs of its oxygen atoms allow DMSO molecules to transfer electrons and accept hydrogen bonds. Unfortunately, these kinds of claims can only confuse the actual and valuable applications of DMSO in medicine. It does not In organic solvents (DMSO, ethanol, chloroform, methylene Antioxidants, such as vitamin C, are important components of good skin care.

In addition to these human uses, the FDA has approved topically applied DMSO for the treatment of musculoskeletal disorders in horses and dogs, and it is widely used in horse racing stables as a pain-relieving liniment. The maximum area of flap ischemia was traced by a masked observer and measured by cut and weigh technique. The most effective DMSO strength for penetrating skin is a solution between 70% and 90%.12,13 For reasons unknown, concentrations higher than 90% are less effective.
