Feverfew, is a name used to describe plants from three different genera of the Compositae.
- Chrysanthemum parthenium (L.) Bernh.
- Pyrethrum parthenium (L.) Sm.
- Tanacetum parthenium (L.) Sch. Bip.
All three species are used in traditional medicine for reducing fever—thus the common name they share—and for treating headaches and migraines and for arthritis.
