What is Feverfew?

Feverfew (Tanacetum parthenium) is a daisy-family herb used for centuries for headaches and fever. Its active compound, parthenolide, appears to calm the inflammatory and blood-vessel changes involved in migraine. Several controlled trials suggest that taking feverfew regularly can modestly reduce how often migraines occur, though it works as a daily preventive rather than a remedy during an attack, and results across studies are mixed. Standardization to parthenolide matters because content varies widely. It is generally well tolerated, with mouth irritation from chewing fresh leaves the classic side effect. Pregnant women should avoid it, and it has mild blood-thinning activity. Typical standardized doses are 100 to 300 mg daily.
