Discussion | Ranunculus bulbosus is native to Europe and the Near East but has become naturalized in many other parts of the world. It is considered an introduced weed in the flora. The Iroquois used Ranunculus bulbosus as a toothache remede and as a a treatment for venereal disease (D. E. Moerman 1986).

Various Navaho groups used Ranunculus cymbalaria as a venereal aid, an emetic, and a ceremonial medicine. The Kawaiisu used it as a dermatological aid (D. E. Moerman 1986). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
