Dimethyl sulfoxide (DMSO) is a chemical compound which is a by-product of wood processing. It is a somewhat oily liquid that looks like mineral oil and has a slightly garlicky odor. It has long been used as a chemical solvent. In the late 1960s, it also became popular as a topical pain relief medication for pulled, strained, and sprained muscles and joints.
