Also known as: Salix alba, White Willow Bark Extract, willow bark, salicin, white willow
White willow bark contains salicin, a naturally occurring compound structurally similar to aspirin, traditionally used for pain and inflammation management. Moderate evidence supports its use for mild-to-moderate joint and musculoskeletal pain, though effects are generally modest.
