Definition of Feverfew
Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026
Feverfew: Tanacetum parthenium (Feverfew) is a member of the sunflower family and has been used for centuries in Europe as a headache remedy. It is most often used today to prevent and treat migraine headaches.
Feverfew can cause allergic reactions, especially in persons who are allergic to ragweed, chrysanthemums, marigolds, or yarrow.
Feverfew may alter the effects of some medications and should be avoided in patients taking medications to prevent blood clotting (anticoagulants) such as warfarin (Coumadin).
Muscle stiffness, anxiety, and moderate pain can occur following cessation of long-term feverfew use in a syndrome called "post-feverfew syndrome".
