Ligusticum canadense, known by the common names of American lovage, boar hog root, and Canadian licorice-root, is a member of the carrot family, Apiaceae. It is native to the eastern United States, primarily in Missouri, Tennessee, Georgia, and North Carolina. Despite its name, the northern range of L. canadense remains hundreds of miles south of the Canadian border.
