Butterbur
(Petasites hybridus)

Butterbur is a true all-rounder in the garden of medicinal plants. Not only does it help with allergies such as hay fever, but it also helps relieve cramps and can even prevent migraines.

The Latin name for butterbur (Petasites hybridus) goes back to its use as a remedy for curing the plague during the Middle Ages. The pungent essential oils were thought to fight the disease. Today we know that it does not cure the plague, but studies have demonstrated its other effects. It is used to treat allergic rhinitis in people who are allergic to pollen (hay fever). It contains what are known as petasines, which have an anti-inflammatory effect and relieve cramp-like symptoms. The extracts from the butterbur root have also been studied to see how they might prevent migraines.

Red or common butterbur (Petasites hybridus) belongs to the sunflower family just like the well-known native daisy or dandelion. This perennial herbaceous plant is found all across Europe and much of Asia.

Butterbur grows in soils that are moist or that flood periodically. To grow, it needs both damp soil and high humidity, which is why it often grows along riverbanks, on alluvial sand banks or in marshy areas. Biologists and ecologists are interested in butterbur because its extensive root system and rhizomes help to stabilise the shores near water. Butterbur often grows prolifically, covering large expanses.

The medicinal plant used to be very common in Switzerland, Germany and Austria. Today it is becoming increasingly rare, however. New invasive species, such as the very fast-growing Japanese knotweed, are displacing it.

Petasites hybridus is an early bloomer, with its flowers appearing between March and May. They form in clusters on a rust-coloured spadix. The reddish, scaled spadix grows higher and higher until the white or pinkish flowers open to form grape-like spadices that can be up to 40 centimetres long.

The large, heart-shaped leaves form once the blooming stage is complete and can have a diameter of up to 60 centimetres. Butterbur can grow to a height of up to 1.5 metres, and the leaves sprout directly from the ground-creeping, partially subterranean rhizome. The plant’s tall stature comes from its leafstalk, which grows to be very long and robust. Both the leafstalk and the undersides of the leaves are covered with whitish-grey, felt-like hairs. The appearance of the plant is also why it is sometimes called the “false” coltsfoot. Coltsfoot, too, has felt-like, hair-covered leaves after its flowering stage that have a similar shape. The leaves of coltsfoot are smaller and have a different shape, however. The flower heads of coltsfoot are also egg yolk yellow and do not have a grape-like formation.

There is evidence that butterbur was used as far back as prehistoric times. In the first century AD, the Greek physician Dioscorides referred to it as “petasos”, which roughly translates to “rain hat”. The name refers to the giant leaves, which were also sometimes used for protection against the rain. In some areas of the German-speaking world, the plant is still referred to as Hutpflanze (“hat plant”).


The German names Pestwurz (“plague root”) and Pestilenzkraut (“pestilence herb”) go back to the plant’s use during the Middle Ages, when the naturally unpleasant odour from the plant itself and the smoke from burning its roots were used to “smoke out” the plague – much in vain, as one might expect.

Extracts from the leaves and roots of the plant have cramp-relieving (spasmolytic) and pain-relieving (analgesic) effects. They also have anti-inflammatory and anti-allergic properties thanks to certain substances they contain known as petasines. These include petasine, isopetasine and neopetasine. Petasines inhibit the production of certain inflammatory messengers, which explains why they have an effect on hay fever.

The plant also contains essential oils, flavonoids, amaroids and mucilage. It also contains carcinogenic and liver-damaging pyrrolizidine alkaloids (PAs). Because of the PA content, people are warned against drinking tea made from the fresh or dried plants. There are standard-regulated extracts from special types of butterbur containing very few PAs, however. The residual PAs are additionally separated from the plant extracts through a complex, complete purification process, and the product undergoes strict testing before it can be used in medicinal products. This includes extract Ze 339, which is used in zeller heuschnupfen.

Studies have shown that butterbur has a wide range of applications. Extracts from the leaves of the plant are used to treat hay fever symptoms. The root extracts of the medicinal plant help relieve cramps that accompany problems with the genitourinary tract and digestive system, for example.

Hay fever relief with products containing butterbur

Most people who suffer from hay fever have tried a whole range of tablets, but many medications, such as antihistamines, cause drowsiness. Products containing an extract from butterbur leaves offer a purely botanical way to relieve allergies. zeller heuschnupfen contains the regulated and standard extract Ze 339, which can provide relief for the full range of hay fever symptoms. These include allergic stuffiness and a runny nose as well as red and itchy eyes or irritations of the throat.

Headaches and migraines

Clinical studies have provided the first evidence that medicinals containing butterbur may also help to relieve tension headaches and prevent migraines. The exact mechanism of action has not been studied yet. Researchers believe that an anti-inflammatory effect and normalisation of blood circulation are partly responsible.

Cramp-like symptoms

Extracts from butterbur root have an antispasmodic effect on the smooth muscles. They are used to treat cramps in the urinary tract and painful cramping in the digestive tract. Products for treating constipation sometimes contain the plant extract because of its calming effect and because it promotes digestion and helps relieve cramps. The senna fruits and fig in zeller feigen mit Senna tablets have a gentle laxative effect thanks to the addition of dry butterbur root extract.

Also available in combination with soothing medicinal plants

Restlessness and nervousness almost always have the same effect on the smooth muscles of our internal organs, and we cannot directly control the tension in these muscles. Such muscles are mainly found in the digestive tract, including the bile and pancreatic tracts as well as the bladder and urinary tract. Restlessness, anxiety and nervousness often have a close relationship with muscle tension in these areas. For example, an anxiety disorder can result in digestive problems accompanied by cramping, which can make emotional stresses even worse. This is referred to as psycho-vegetative coupling. For this reason, zeller entspannung contains valerian root, lemon balm and passionflower, which mainly have a calming effect on certain regions of the brain thanks to the combination with butterbur root extract. It also has a relaxing effect on the smooth muscle organs.
