Discussion | Ranunculus sardous was collected in New Brunswick and Ontario in the 1800s, but it apparently has not persisted in those provinces. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
