“Common Feverfew has large, fresh, green leaves, much torn or cut on the edges. The stalks are hard and round, set with many such like leaves, but smaller, and at the tops stand many single flowers, upon small foot stalks, consisting of many small white leaves standing round about a yellow thrum in the middle.”
The Complete Herbal by Nicholas Culpeper 1653

Feverfew is a herb with a long history of traditional use going back to the Middle Ages. The plant, a member of the daisy family, looks somewhat similar to camomile at first glance. It has a strong distinctive smell and is particularly disliked by bees. It grows wild in many parts of Europe and the British Isles.6

Action and uses of Feverfew
Feverfew received a great deal of attention in the UK during the 1980s when several research studies showed that 100mg of dried leaf daily could help reduce the frequency and severity of migraine attacks, if taken regularly over a period of months.1,3,4 Further research has supported the use of feverfew for the prevention and treatment of migraine, tension headache and associated symptoms.2
Most of the research has been carried out using dried leaf preparations. Capsules containing 100 to 125mg of dried feverfew leaf are recommended.		  

How much do you take?
At least 100mg dried leaf daily. This would typically be one capsule a day. Take for at least one month in order to gain benefit. Maximum benefit is often achieved only after taking Feverfew leaf on a daily basis for several months. Feverfew can safely be taken on an ongoing basis.5
