Butterbur

(Petasites hydridus)

Butterbur is a woodland plant that is a member of the daisy family. It grows freely in damp conditions throughout Europe and the British Isles. Petasites means “large brimmed hat”, which is the best way to describe the large, round leaves. The root and leaves are used in herbal medicine.

Traditionally the entire plant was used as a demulcent to soothe a dry, spasmodic cough. It was primarily made into a tea, and used only for short periods of time. Using the herb as a tea may have helped reduce the liver’s exposure to butterbur’s toxic compounds, as they are not normally water soluble.

What it does
