Petadolex® Pro-Active supports healthy blood vessel relaxation in the brain.*

Butterbur (Petasites hybridus) contains several compounds with bioactive properties. Two of these compounds, petasin and isopetasin support healthy blood vessel tone.*

Enzymatic Therapy's Petadolex® Pro-Active supplement contains pure butterbur extract to support healthy blood vessel tone in the head.*

The patented method of extraction for Petadolex Pro-Active ensures the valuable petasites compounds are captured, while leaving out toxic levels of inherent compounds such as pyrrolizidine alkaloids. This product is tested for pyrrolizidine alkaloids, made possible by using this patented process (U.S. Patent #6,551,626).
