Facts

Canada wild ginger is found in rich, moist forests in much of New England. It is unrelated to the ginger commonly used in cooking, but the root has a strong, ginger-like flavor. Native Americans used it in cooking and to treat a wide variety of maladies, including coughs, colds, stomach pains, and poor digestion.
