Ingredient Type: Botanical, Extract

Also Known As: Salix alba, Golden willow

White willow bark comes from a small tree or shrub found on all continents except Antarctica and Australia.  The medicinal use of willow dates back 6,000 years.  Ancient civilizations used willow tree extracts for pain, inflammation, and musculoskeletal conditions.

Researchers have found it to contain salicin, which is chemically similar to aspirin (acetylsalicylic acid), along with flavonoids.  Together these are thought to ease pain and discomfort.

White willow bark is used in health supplements today to help with general aches and pains.
