The Active Ingredient Is: Salicin

Salicin is a natural compound derived from willow bark that serves as a precursor to salicylic acid and contributes to traditional analgesic properties.

This form is supplied within a willow bark extract standardised to salicin, and the product also contains natural polyphenols and flavonoids that contribute to antioxidant action.

What Does Salicin Do?

Salicin is metabolised to salicylic acid and is involved in the inhibition of COX enzymes, which reduces the synthesis of pro-inflammatory prostaglandins and supports normal pain and inflammatory responses. The bark's polyphenols and flavonoids assist with antioxidant activity.
