White willow (Salix alba ) is a species of willow native to Europe and western and central Asia. White willow trees are often short-lived due to the susceptibility of their bark to diseases, including watermark disease and anthracnose. The undersides of white willow tree leaves are covered in fine, silky white hairs, thus the name “white willow”. White willow tree bark has been used as a remedy for pain and fever dating back to ancient times and is mentioned in texts from ancient Egypt and Assyria. Aspirin is a chemical derivative of Salix alba bark extract.
