Species Notes
Description
Petasites hybridus, also known as the butterbur, is a herbaceous perennial flowering plant in the family Asteraceae that is native to Europe and northern Asia. Although used over centuries in traditional medicine to treat various disorders, there are no approved medical uses, but it is sold as a dietary supplement. Concerns about the potential toxic effects of pyrrolizidine alkaloids in butterbur limit its use in human and animal studies.
