I was just wondering if anyone has had any success with butterbur extract as a supplement for fighting post concussive headaches. My doctor suggested it to me and I wanted to see if anyone has any suggestions about a specific type or brand of butterbur that has worked for them. Also, I am seeing that it often is taken in some sort of combination with feverfew which I don't know much about. If anyone has any suggestions about feverfew that would also be helpful. Any information is much appreciated. Thanks!
