What is Butterbur Extract?

Butterbur leaf extract (Petasites hybridus) is a shrub. Its large leaves were used to wrap butter during warm weather, giving it the name "butterbur".Butterbur grows throughout Europe and parts of Asia. It's also now found in parts of the US. Butterbur contains chemicals that might relieve spasms and decrease swelling.

Butterbur leaf extract is used for migraine, hay fever, asthma, and many other conditions, but there is no strong scientific evidence to support most of these uses. Some butterbur products may contain pyrrolizidine alkaloids (PAs). These chemicals can harm the liver and cause serious side effects. Do not use butterbur products unless they are certified as free of PAs.

Butterbur Extract Benefits:

The name, butterbur leaf extract, is attributed to the traditional use of its large leaves to wrap butter in warm weather. In the Middle Ages butterbur was used for plague and fever, and in the 17th century it was used to treat cough, asthma, and skin wounds.


In 2012, based on two high-quality studies, the American Headache Society (AHS) and the American Academy of Neurology (AAN) endorsed the use of a butterbur extract made from underground parts of the plant, like the root or rhizome, to reduce the frequency of migraines.

The exact way butterbur leaf extract works is unknown, though it's believed to be linked to the anti-inflammatory and other effects of the active component called petasin—for instance, it likely relaxes blood vessels in the brain that become overexcited during a migraine. Regardless of the mechanism, a study published in 2004 found that at a dose of 75 milligrams twice daily, taken for up to three to four months, butterbur was been reduced the frequency of migraine headaches when compared to placebo with no significant adverse effects.

Allergic Rhinitis (Hay Fever)

Butterbur has been used traditionally to treat asthma and bronchitis and to reduce mucus, and a 2007 evaluation of six studies of the herb for allergic rhinitis, involving a total of 720 participants, indicated that butterbur may be helpful. Although how butterbur works still isn't known, it's thought to work in a similar way to allergy medications by blocking the action of histamine and leukotrienes, inflammatory chemicals involved in allergic reactions.

In an earlier study of 330 people, published in 2004, butterbur extract was compared with the antihistamine drug Allegra (fexofenadine) and a placebo. Butterbur was as effective as Allegra at relieving sneezing, nasal congestion, itchy eyes, and other hay fever symptoms, and both treatments were more effective than the placebo.5 A 2002 study of 125 people with hay fever found a butterbur extract to be as effective as Zyrtec (cetirizine).6 It's worth noting that some of the larger trials were sponsored by manufacturers of butterbur extract and at least one double-blind, placebo-controlled study with negative results was published in 2004
