Discussion | 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.) |
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.
