The white willow can be found next to rivers and streams throughout the country. The leaves contain salicylic acid, which has been synthesized into acetylsalicylic acid, known as aspirin, which has been used for centuries worldwide as a pain reliever. Willow bark contains other compounds that the body metabolizes to salicylic acid. For this reason willow bark acts more slowly and over a longer period of time than aspirin does. The compound salicin from willow does not cause gastric or intestinal upset or bleeding as aspirin can. This is because willow suppresses the action of prostaglandins (hormone-like substances) in the stomach or intestines, which are produced by the body in response to injuries. Claims and Common Uses:
