Rubus idaeus is the source of most of the cultivated red and amber raspberries. Plants were used by the Cherokee, Cree, and others as a parturient; an infusion of dried leaves in water was used to prepare the uterus for childbirth and help women recover after childbirth (D. E. Moerman 1998; D. Hoffman 2003).
