The willow family includes a number of different species of trees and shrubs native to Europe, Asia, and some parts of North America. Some of the more commonly known species are white willow/European willow (Salix alba), black willow/pussy willow (Salix nigra), crack willow (Salix fragilis), purple willow (Salix purpurea), and weeping willow (Salix babylonica). Not all willow species accumulate a therapeutically sufficient amount of salicin. In one study, the amount of salicin after 1 and 2 year growth in autumn and spring ranged from 0.08 to 12.6%. The willow bark sold in Europe and the United States usually includes a combination of the bark from white, purple, and crack willows.
