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.
Industrial-grade DMSO is not of the same quality as the DMSO that is used for drug research purposes since it may contain impurities. DMSO easily penetrates the skin and brings along impurities and other substances that may be hazardous to health.
