Patient Education

Willow Bark


What is it? Willow bark is the bark from several varieties of the willow tree, including white willow or European willow, black willow or pussy willow, crack willow, purple willow, and others. The bark is used to make medicine.

Willow bark acts a lot like aspirin. It's most commonly used for pain and fever. But there is no good scientific evidence to show that it works as well as aspirin for these conditions.

Coronavirus disease 2019 (COVID-19): Some experts warn that willow bark may interfere with the body's response against COVID-19. There is no strong data to support this warning. But there is also no good data to support using willow bark for COVID-19.
