Butterbur Extract 

Butterbur Extract contains Petasins and is produced from the leaf of the Petasites Hybridus plant. The Butterbur (Petasites japonicus) has been a staple of the Japanese diet for many years and is one of the few vegetables native to Japan. It has anti-allergenic properties. Petasin is responsible for the antispasmodic properties of the plant by reducing spasms in smooth muscle and vascular walls in addition to providing an anti-inflammatory effect by inhibiting leukotriene synthetics. It can be used in supplements to treat migraine headache, asthma, bronchitis, cough, urination and stomach problems.
