DMSO (dimethyl sulfoxide) is a natural product from trees and despite its chemically sounding name is known to be one of the least toxic substances in biology (Parcell, 2002).

DMSO is an organosulfur compound.This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is a great transdermal enhancer.

A little goes a long way with this so just a drop is all that is required.
