Whorled rosinwood may prove one day to be among our most useful native plants. It has been studied or is currently under study for a range of uses, from fodder and honey production, to medical and industrial uses.
According to The Medicinal Plant Garden of Birmingham-Southern College:
"Chippewa [people] used the simple or compound decoction of the root for 'stoppage of periods,' for back and chest pain and for lung hemorrhage. A poultice of moistened, dried root was applied to wounds to stop bleeding.
[Haudenosaunee people] used the decoction of roots as an emetic and as face wash for paralysis. Burned root soot was placed on a child’s cheek to prevent them from seeing ghosts. Meskwaki used the root to 'alleviate the vomiting of pregnancy.' Infusion of root taken by women to prevent premature birth. Root used to reduce profuse menstruation and as an anti-emetic during pregnancy.
Ojibwa [people used an] infusion of root taken for lumbago and other rheumatic back pains, stomach trouble and hemorrhage.
Cup plant’s young leaves were cooked in the spring as a green (Kindscher 1987). It was also used as a chewing gum to help prevent vomiting (Runkel & Roosa 1989). The Winnebagos [Ho-Chunk people] believed that this species has supernatural powers. They would drink a concoction derived from the rhizome to purify them before going on a buffalo hunt. It is used in the treatment of liver and spleen disorders and has also been used to treat morning sickness (Moerman 1998)."
Our seed was produced by our friends at Ernst Conservation Seeds in Meadville, PA.
