Overview

Willow bark comes from several varieties of willow tree, including white (Salix alba or European), black (Salix nigra or pussy), crack, and purple willow.

Willow bark contains a chemical called salicin, which is similar to aspirin. It has pain and fever reducing effects in the body.

People commonly use willow bark for back pain, osteoarthritis, fever, flu, muscle pain, and many other conditions, but there is no good scientific evidence to support most of these uses. There is also no good evidence to support using willow bark for COVID-19.
