The word "feverfew" derives from the Latin febrifugia, meaning "fever reducer." It has been used for reducing fever, for treating headaches, fevers, arthritis and digestive problems. Feverfew is also used to treat menstrual irregularities, labor difficulties, skin conditions, stomach aches, and asthma.Feverfew may also have GABAergic effects. Its main active ingredient parthenolide has also been found in 2005 to induce cell death in leukemia cancer stem cells. Feverfew has been used to calm red and irritated skin.

Feverfew products usually consist of dried feverfew leaves, but all parts of the plant that grow above ground may also be used for medicinal purposes. The active ingredients in feverfew include parthenolide and tanetin, and Feverfew also contains a relatively large amount of melatonin. The migraine-relieving activity of feverfew is believed to be due to parthenolide, an active compound that helps relieve smooth muscle spasms. In particular, it helps prevent the constriction of blood vessels in the brain (one of the leading causes of migraine headaches). Parthenolide also inhibits the actions of compounds that cause inflammation and may inhibit cancer cell growth.
