Latin Name: Salix alba
Common Names: White Willow Bark
The bark of white willow contains salicin, which is a chemical similar to aspirin (acetylsalicylic acid). In combination with the herb's powerful anti-inflammatory plant compounds (called flavonoids), salicin is thought to be responsible for the pain-relieving and anti-inflammatory effects of the herb.
Warning: Use in persons with sensitivity to aspirin or other salicylate-containing drugs is cautioned. Use in persons with glucose-6-phosphate dehydrogenase (G6PD) deficiency is cautioned.
