Asarum

Asarum, popularly known as wild ginger, Indian ginger and Canada snakeroot, has kidney shaped leaves and a ginger flavored rhizome tasting root; however, it is not related to the common ginger used in various culinary preparations. Because of the jug shaped leaves, this herb is also known as “little jug”. The root of wild ginger is used as a spice in these regions, but also has some side effects, which need to be taken into account. It is also referred as asarabacca and is a low growing birthwort herb, which is a collective reference to all the species of this plant.
