Good studies have demonstrated the effectiveness of the herb butterbur (Petasites hybridus) in preventing migraines. [139] A guideline from the American Academy of Neurology and the American Headache Society (AAN/AHS) recommends offering butterbur to patients with migraine to reduce the frequency and severity of migraine attacks (level A recommendation).
