Feverfew for Migraines

€4.75 for 45 Capsules of Feverfew (250mg), additive free. I went ahead and decided to give it a go on recommendation from a Health Food Store local to me. Well, I've bene taking it for a few days now, I've had two late nights and I haven't had my mandatory 'aura' or threat of a migraine with the rush to take as many pills as is safe to stave it off. I've even got a head cold at the moment and I'm still not suffering yet. I wonder if I've found something that really will help to reduce the frequency of these life altering migraines. Have any of you tried Feverfew? What was your experience with it?
