Petadolex®
If you suffer from debilitating headaches, here is some good news. Petadolex® gelcaps contain a standardized extract from the butterbur plant. Butterbur (petasites hybridus) was mentioned by the ancient Greeks around 100 AD. It was used in the middle ages to treat the plague. In traditional phytotherapy, petasites hybridus is described as having spasmolytic (muscle-relaxing) effects.
