Unsaponifiables are components of an oily (oil, fat, wax) mixture that fail to form soaps when treated with sodium hydroxide (lye) or potassium hydroxide.

It works by blocking pro-inflammatory chemicals and preventing the deterioration of the cells that line the joints. It may also help regenerate connective tissue.
