studies point to butterbur extract (petasites hybridus root) as a
migraine treatment. Butterbur has been recommended for migraine
before, but now the scientific evidence is starting to catch up. The
dosages in recent studies for both children and adults range between
50mg and 150mg. It is recommended that you use a reliable
standardized and safe form of butterbur. In a recent German study,
Petadolex was used, which is a butterbur extract.
