This little-known, though quite common, Ginseng seems to have been forgotten from medicine. Native Americans (Iroquois, Cherokee, and Ojibwa) used it; and Chinese reverence for Notoginseng and other Panax species besides the primary Panax ginseng (Chinese Ginseng, Asian Ginseng, Korean Ginseng, or just Ginseng) indicates that maybe we should pay attention to this little, transient (just 2 months above ground) herb.
These uses align with the many of the primary uses of other Ginseng (Panax) species. The uses cited by Moerman (see his text Native American Ethnobotany and his sources for more information) indicate that Dwarf Ginseng is chi tonic, anodyne, and blood regulating; like other species.
