Feverfew extract is a botanical derived from Tanacetum parthenium used in skincare for its antioxidant and anti-inflammatory properties, often to calm redness and irritation. Cosmetic formulations typically use parthenolide-depleted feverfew to reduce sensitization risk while retaining soothing benefits.
