Wow I am surprised that your MD recommended an herbal remedy! Pleasantly surprised, I should say. Anyhow, I used to take it and I think that it helped. Reduced the frequency and severity of my migraines close to the 40% that's been found in studies. Of course, every person is different as far as their experience with different drugs & whatnot. I will say that if you've just started taking it, be patient (I know, easier said than done!). It was about 6 weeks before I had these positive results.
