Feverfew Herb – Uses And Side Effects


A European plant now cultivated in the United States and Canada, feverfew bears yellow flowers and yellow-green leaves from July to October. Usually, the leaves are dried or used fresh in teas and extracts. The most common botanical name for feverfew is Chrysanthemum parthenium.

Feverfew tree grow to heights of between 9 inches and 2 feet. The deeply cut leaves are brightly colored and have a sharp, unpleasantly bitter taste. The flowers, which are produced from summer until mid-fall, are thick and daisy like with yellow centers.

The chemical parthenolide has the highest concentration in the leaves and flowering tops during the summer, before the seeds are set. The parthenolide level drops rapidly thereafter. This may explain the difference in parthenolide levels between brands of feverfew capsules and tablets. The herb was somewhat forgotten, however, until the late 1970s. That’s when migraine sufferers started talking about feverfew’s potential to ward off these often debilitating headaches
