| herb. Thankfully, these doctors had the inquiring and open minds of true scientists and so started their own investigations into the claims for feverfew. Clinical observations were soon reported in peer-reviewed medical journals. |
| The first double-blind study was done at the London Migraine Clinic, using patients who reported being helped by feverfew. 7 Seventeen patients who regularly ate fresh leaves of feverfew daily to prevent migraine were invited to participate in a double-blind, placebo-controlled trial of the herb. Of these, eight patients received capsules containing freeze-dried feverfew powder and nine, a placebo. Those patients who received the placebo (and as a result stopped using feverfew) had a significant increase in the frequency and severity of headaches, nausea and vomiting during the six months of the study as well as the reemergence of untoward effects during the early months of treatment. The group given capsules of feverfew, on the other band, showed no change in the lack of symptoms of migraine, providing clear evidence that feverfew can prevent attacks of migraine. Two patients in the placebo group who had been in complete remission during self-treatment with feverfew leaves developed a recurrence of incapacitating migraine and had to withdraw from the study. The resumption of self-treatment led to renewed remission of symptoms in both patients. This led the researchers to strongly suggest the use of feverfew for all migraine sufferers. |
| Another double-blind study was performed at the University of Nottingham. The results of the study clearly demonstrated that feverfew was effective in reducing the number and severity of migraine attacks and confirmed that a daily intake of feverfew prophylactically prevents attacks of migraine.8 |
| Follow-up studies to clinical results have shown feverfew works in the treatment and prevention of migraine |
