Text Box: Dimethyl sulphoxide (DMSO), discovered in 1867, is a dipolar aprotic solvent with some interesting properties. It is obtained as a by-product from the wood pulping process. It penetrates skin extremely readily so is very effectively absorbed into the body. After contact with skin on the hands it can be tasted in the mouth within seconds, and is said to have a garlic-like taste. People who have taken DMSO for medical reasons may develop a garlicky odour!
