Butterbur, or Petasites hydridus, is found in colder, northern regions of Russia and Europe. A species native to the northern United States and much of Canada is Petasites frigidus. All parts of either plant are used, including root, rhizome, leaves, and flowers. Both species are easily confused with their close cousin, Eastern coltsfoot (Tussilago farfara), a plant that looks the same and has similar properties and hazards.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditionally the entire plant was used as a demulcent to soothe a dry, spasmodic cough.1 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.
