Feverfew (Tanacetum parthenium Asteraceae/Compositae)

Other Names: Altamisa

This hardy herbaceous perennial, native to Anatolia in the Middle East, grows to about 60 centimeters and resembles a cross between a daisy and chamomile. Its leaves and flowers emit a strong, bitter scent. Historically, feverfew was planted around homes as a protective measure against diseases.

Parts for Use

Use in Treatment

Feverfew is a key herbal remedy for headaches caused by blood vessel dilation and constriction, as well as migraines, menstrual pain, fever, asthma, and other inflammatory conditions.
