Petasites hybridus (Butterbur) is used for which indication?

Butterbur is best used for migraine prevention. Its active constituents, such as petasins, in standardized extracts have anti-inflammatory and smooth-muscle–relaxing effects that can dampen the vascular and inflammatory processes thought to contribute to migraine attacks. Clinical trials of PA-free butterbur extracts show a reduction in the frequency, and often the severity and duration, of migraine episodes, supporting its role as a preventive option rather than an acute treatment. It isn’t a primary treatment for diabetes, heart disease, or asthma, though anti-inflammatory properties can be beneficial in some allergic conditions; the strongest evidence and traditional use point to migraines. Safety note: use PA-free formulations to minimize risk of liver toxicity from pyrrolizidine alkaloids.
