Asarum canadense, commonly known as Canada wild ginger, Canadian snakeroot and broad-leaved asarabaccais, is a herbaceous perennial native to deciduous forest in eastern North America, from the Great Plains east to the Atlantic Coast, and from southeastern Canada south to approximately the fall line in the southeastern United States.
The plant contains aristolochic acid, a carcinogenic compound. The United States Food and Drug Administration warns that consumption of aristolochic acid-containing products is associated with "permanent kidney damage, sometimes resulting in kidney failure that has required kidney dialysis or kidney transplantation. In addition, some patients have developed certain types of cancers, most often occurring in the urinary tract."
The long rhizomes of A. canadense were used by Native Americans as a seasoning. It has similar aromatic properties to true ginger (Zingiber officinale), but should not be used as a substitute because it contains an unknown concentration of the carcinogen aristolochic acid and asarone. The distillate from the ground root is known as Canadian snakeroot oil. The odor and flavor are spicy. It has been used in many flavor preparations.
Native Americans used the plant as a medicinal herb to treat a number of ailments including dysentery, digestive problems, swollen breasts, coughs and colds, typhus, scarlet fever, nerves, sore throats, cramps, heaves, earaches, headaches, convulsions, asthma, tuberculosis, urinary disorders and venereal disease. In addition, they also used it as a stimulant, an appetite enhancer and a charm. It was also used as an admixture to strengthen other herbal preparations.
