Butterbur or Petasites hybridus is a perennial, flowering, wetland plant in the Aster or Asteraceae family. Native to Europe, it was named for its large leaves once used to wrap butter in warm summer months. In the Middle Ages, Butterbur was prescribed to plague victims, while in the 17th century, it was administered to ease cough and asthma. Leaves, roots and rhizomes have anti-inflammatory properties and are used in the treatment of migraines, allergic rhinitis, stomach issues and urinary tract infections.
