Willow bark has been used for centuries as a pain reliever. It contains an active ingredient called salicin, which is closely related chemically to aspirin and has a very similar action in the human body. Salicin is an alcoholic β-glucoside that contains D-glucose. It is a prodrug, which is converted to salicylic acid after absorption. It has pain and fever-reducing effects on the body and possesses anti-inflammatory properties.
