Salix alba is a medium-sized deciduous tree with long, green, tapering leaves and grey-green bark. White willow bark has a history of use in traditional European herbalism for its beneficial properties. Willow bark contains the active constituent salicin, the chemical compound that led to the creation of aspirin. White willow bark powder can be infused, encapsulated, tinctured, or applied topically.

Native to North America, northern Asia, and much of Africa, the willow is a low-growing deciduous tree bearing long, green, tapering leaves and catkins in spring. Bark is stripped from young trees in the spring. Native American healers used willow bark long before Columbus or the Vikings landed. The conversion of willow bark to aspirin began in 1828 when German chemist Felix Hoffmann isolated the active ingredient and named it salicin. In 1899, the Bayer company began manufacturing and selling a modified form of the willow bark chemical acetylsalicylic acid, or aspirin. This first of the modern miracle medicines has been a mainstay in the treatment of joint pain ever since. White willow (also called bai liu pi in Traditional Chinese Medicine) is a member of the Salicaceae family.
