Oral and Topical Use of Supplements and Botanicals to Help Alleviate Pain and Adverse Side Effects
Two other herbs used often for headache, including migraines, are butterbur (Petasites hybridus) and feverfew (Tanacetum parthenium).
Clinical studies support their use to prevent and to reduce duration, frequency, and pain of migraines. Butterbur is also used in Europe to treat seasonal allergies. Root compounds are believed to inhibit mast cells. Butterbur contains pyrrolizidine alkaloids (PAs) that can harm the liver, and in Europe, regulations require that butterbur preparations be PA free.
In addition, butterbur extracts should contain at least 7.5 mg per dose of both petasin and isopetasin. Feverfew is used widely in the US, Europe, and Australia. Chewing the fresh leaf may lead to mouth ulcers. Long-term users who stop taking feverfew abruptly have experienced a withdrawal syndrome. In general, however, feverfew is safe and well-tolerated.
