USES
Recent 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.
