Feverfew

Introduction
This fact sheet provides basic information about the herb feverfew—common names, uses, potential side effects, and resources for more information. Originally a plant native to the Balkan mountains of Eastern Europe, feverfew—a short bush with daisy-like flowers—now grows throughout Europe, North America, and South America.

Common Names—feverfew, bachelor's buttons, featherfew

Latin Names—Tanacetum parthenium, Chrysanthemum parthenium

What Feverfew Is Used For
Feverfew has been used for centuries for fevers, headaches, stomach aches, toothaches, insect bites, infertility, and problems with menstruation and with labor during childbirth.
Recently, feverfew has been used for migraine headaches and rheumatoid arthritis.
Feverfew has also been used for psoriasis, allergies, asthma, tinnitus (ringing or roaring sounds in the ears), dizziness, nausea, and vomiting.
 

How Feverfew Is Used
The dried leaves—and sometimes flowers and stems—of feverfew are used to make supplements, including capsules, tablets, and liquid extracts.
The leaves are sometimes eaten fresh.
 

What the Science Says
Some research suggests that feverfew may be helpful in preventing migraine headaches; however, results have been mixed and more evidence is needed from well-designed studies.
One study found that feverfew did not reduce rheumatoid arthritis symptoms in women whose symptoms did not respond to conventional medicines. It has been suggested that feverfew could help those with milder symptoms.
There is not enough evidence available to assess whether feverfew is beneficial for other uses.
NCCAM-funded researchers have studied ways to standardize feverfew; that is, to prepare it in a consistent manner. Standardized preparations can be used in future studies of feverfew for migraines.
