What's the main active ingredient of white willow bark extract?
The main active ingredient of white willow bark extract (SALIX ALBA) is salicin, an anti-inflammatory agent made from willow bark, which is metabolized into salicylic acid by the human body.

In a patent titled "Use of salicin as an anti-irritant compound in cosmetic and topical skin preparations," salicylic acid is recognized as an effective ingredient "in the control and prevention of so-called 'stings', Atopic dermatitis, type I and IV skin irritation can be treated with salicin, and the irritation threshold of sensitive skin can be increased with salicin."
