NOW Foods Feverfew 100 Veg Capsules provides a standardized extract of Tanacetum parthenium aerial parts, a medicinal herb with a centuries-long history of use in European herbal medicine for the prevention of migraine headaches. The active compounds in feverfew, primarily parthenolide sesquiterpene lactones, are believed to inhibit platelet aggregation and the release of inflammatory compounds from blood platelets and white blood cells that may contribute to migraine onset. This formula is standardized to ensure consistent parthenolide content per capsule for reliable, reproducible results.

Non-GMO, vegan, and produced in a GMP-certified facility. 100 veg capsules per bottle.
