• 化学的特性

  The several known Asarum species find various applications, depending on the botanical classification. A. canadense, not to be confused with A. europaeum L., is a perennial herb growing preferably in shady, humid, woody areas in Canada and the northern United States. European Asarum differs from the Canadian variety, not only in its main constituents, but also in its vegetative form. The essential oil from A. europaeum is poisonous and is not prepared for commercial use. Aristolocholic acid is the toxic constituent. The rhizome is the only part used. Canadian snakeroot has a strong, characteristic, spicy odor and flavor reminiscent of ginger.
