Used to prevent migraine headaches. Also used for sinus pressure and headache.

My son takes one before an intense workout to prevent a migraine attack. It is best taken beforehand or when you feel the migraine coming on. It does not seem to work when the migraine is full flown and/or you already feel nauseous. I take it for mild headaches. It also alleviated sinus pressure caused by allergies.

Remarkable results

Posted by Reviewer2852152 on Dec 05, 2010

I've been taking NOW butterbur with feverfew for several years for migraines (mine are brought on by sensitivities to foods, some herbs, and toxins, not hormonal). The NOW product did reduce severity of migraines by around 75% (almost never a bad headache anymore - just the aura and sometimes a slight headache). Along with migraines, I've recently been plagued by cystitis (bladder pain). For some reason (maybe NOW was out of stock at the time), I decided to try this product instead of the NOW product, not really having any expectations regarding the cystitis. So, here are my results: so far, fewer migraines as well as still much less severe than before butterbur *and* bladder pain/cystitis is almost gone!! I've even tested some of the foods that seemed to aggravate the situation, and so far, no problem!! I am very impressed and of course very happy. Will continue to use this product over NOW even though it's more expensive. Update 12/5/10: Well, unfortunately bladder pain has returned. Interstitial cystitis isn't easy to treat and comes and goes. I'm now trying marshmallow root, slippery elm, and colostrum. Still love this product for the migraine benefit though.
