Petasites hybridus, the (common) butterbur is a herbaceous perennial plant in the family Asteraceae, native to Europe and northern Asia.

Description

Similar to Petasites hybridus but with larger leaves.[1] The flowers are produced in the early spring, before the leaves appear; they are pale pink, with several inflorescences clustered on a 5–20 cm stem. The leaves are large, on stout 80–120 cm tall stems, round, with a diameter of 40–70 cm. It is also called bog rhubarb, Devil's hat and pestilence wort. Synonyms include P. officinalis, P. ovatus and P. vulgaris.

Herbalism

Petasites hybridus leaves have been used in the traditional Austrian medicine internally (as tea or cold maceration in ethanol) and externally (as compresses or maceration in vinegar) for treatment of infections, fever, flu, colds, hay-fever and allergies.[2]

In one study, published recently in the British Medical Journal, a group of Swiss researchers showed how just one tablet of butterbur extract (Ze 339) four times daily was as effective as a popular antihistamine drug in controlling symptoms of hay fever—without the traditional symptom of drowsiness that sometimes occurs.

In a second study, presented at the 60th annual meeting of the American Academy of Allergy, Asthma, and Immunology (AAAAI), a group of British researchers put their stamp of approval on butterbur's effectiveness in quelling symptoms of grass allergy.

Another study was done and published in February 2014, by Ray Sahelian, M.D., describing the benefits and side effects of Petasites Hybridus.

The herbalist Nicholas Culpeper called it "a great preserver of the heart and reviver of the spirits". Its many uses in folk medicine include applications as a diuretic and muscle relaxant, and to treat coughs, fever, wounds, stammering, headaches, asthma and stress. Not all of these uses are supported by scientific research.

Potential medicinal uses

Preliminary trials have shown a preparation of Butterbur root to be effective in reducing the frequency and severity of migraine attacks.[3] A commercial extract Petasol butenoate complex (Ze 339) has proved helpful for allergic rhinitis[4][5] An evidence-based 2005 systematic review including written and statistical analysis of scientific literature, expert opinion, folkloric precedent, history, pharmacology, kinetics/dynamics, interactions, adverse effects, toxicology, and dosing is available from the Natural Standard Research Collaboration.[6]
