Dimethyl sulfoxide (DMSO), a by-product of the wood industry, has been in use as a commercial solvent since 1953. It is also one of the most studied but least understood pharmaceutical agents of our time--at least in the United States.
In addition to DMSO's direct use in the treatment of the above infirmities it is also very often used as a vehicle to deliver other drugs to afflicted areas. DMSO's is widely considered ideal for this purpose because of its ability to penetrate the skin and its preferential scavenging of hydroxyl radicals.MSO, however, is the relatively inexpensive by-product of the wood pulping process and has been in the public domain too long to be subject to proprietary claims. Pharmaceutical companies therefore have no incentive to bring DMSO through the approval process.
