Introduction Willow bark has been used as a traditional medicine for more than 3000 years not only as pain reliever and antipyretic, but also as a soothing agent & in the treatment of skin disorders. The active substance, salicilin, was isolated in the late 1820s, purified in the late 1930s and named salicylic acid. Salicylic acid is still used medically as keratolytic, anti-microbial, anti-fungal agent, and as a synthesis intermediate in the production of many active pharmaceutical ingredients. Seqens is the sole european producer of salicylic acid, vertically integrated. The proprietary production process of salicylic acid, with a single step up to pharma grade, is the ultimate guarantor of an exceptionnal purity and a unique carbon footprint.
