North American Ginseng was an important medicine for people of the First Nations and has traditionally been used to traet a wide range of digestive disorders. Herbalists have used ginseng to treat indigestion and loss of appetite.
Recent studies in laboratories have demonstrated the potential for Ontario grown ginseng in the treatment of chemotherapy-induced nausea and vomiting. An extract of North American ginseng berries reduced the nausea and vomiting associated with the chemotherapeutic agent, cisplatin, and resulted in significant recovery of food intake. The antioxidant action of Ontario-grown ginseng is thought to play a role in counteracting the symptoms of nausea and vomiting.
