Discussion | Clematis lasiantha is common in the Coast Ranges and the foothills of the Sierra Nevada of California. The Shasta used pounded stems or chewed or burned roots of Clematis lasiantha medicinally in the treatment of colds (D. E. Moerman 1986).

Formerly Clematis viorna was locally naturalized near Guelph, Ontario; no recent reports are known. D.S. Correll and M.C. Johnston (1970) mention "a report of a specimen" from Texas; neither the specimen nor further details have been located. The Fox Indians prepared a drink from the roots of Clematis viorna to use medicinally as a panacea (D. E. Moerman 1986).
