DMSO refers to Dimethyl Sulfoxide which has the chemical formula of C2H6OS. It is an important type of polar aprotic solvent. It is a colourless liquid. It readily absorbs into skin and tastes either like garlic or oyster like. It is widely used as a solvent in various chemical reactions and is a by-product obtained from the wood pulping industry. Due to its ability to be readily absorbed by organic tissue and skin it is used in medicine to administer medication. It is also used in the preservation of human organs and is used in the preservation of haematopoietic and embryonic stem cells. Saline on the other hand is a solution of sodium chloride. It is used in the rinsing of contact lenses, in intravenous infusion and in nasal irrigation. Depending on the degree of salinity the appropriate purpose gets defined.
