Dear Dr. Roach: A few years ago, I read that the herbal supplement feverfew may help with some migraines. Having suffered with severe migraine for over 50 years, I decided to try it. I take one capsule four times a day, and it has completely rid me of my migraines. Would you please mention it again? B.J.F.
Answer: Feverfew is a common herbal remedy to prevent migraine, and although not all trials have shown benefit, the majority of studies I have read showed that it is more effective than a placebo treatment and the side effect risk is very small. Other nonprescription treatments that have been shown in most studies to be beneficial include magnesium, riboflavin and coenzyme Q10. These treatments are generally safe and well-tolerated, and I hope other people may get the same relief you have found.
