Quick Take

A natural salicylate option for chronic back or joint pain, but weaker and slower than NSAIDs; avoid if allergic to aspirin.

White willow bark is the bark of the Salix alba tree, a natural source of salicin that the body converts to salicylic acid. It has been used for centuries as a traditional analgesic and antipyretic. Modern clinical trials focus mainly on chronic lower back pain and osteoarthritis, where it shows modest benefits over placebo. Its mechanism resembles aspirin—reducing prostaglandin production via COX inhibition—but acts more slowly and with lower potency. Adults with chronic musculoskeletal pain who prefer herbal options or cannot tolerate standard NSAIDs may find it worthwhile, though it is not

How It Works

Salicin and related polyphenols are absorbed and metabolized to salicylic acid, which inhibits cyclooxygenase (COX) enzymes. This lowers prostaglandin synthesis, dampening pain signaling and local inflammation. Unlike acetylsalicylic acid (aspirin), willow bark lacks the acetyl group and produces a slower, weaker pharmacokinetic effect.
