A glucoside, obtained from the bark of various species of Salix or willow tree, and from Gaultheria procumbens or wintergreen.
Salicin is a bitter tonic, and to some extent an antipyretic and antiseptic. Its qualities resemble, though in a very mild degree, those of salicylic acid, which is derived from it. Salicin is not poisonous. It is very insoluble, and is given dry on the tongue or in capsules.
