• Temperate Medicinal Plant Biogeography and Conservation

Speaker: Marc Williams, MA We discuss several of the major medicinal plants growing in the cold areas of the world that are often used in herbalism. We review where these plants originate and the current state of their conservation. The work of United Plant Savers in plant preservation is a major topic of discussion. The need for more cultivation of various species and resources to assess sustainability of harvest will round out our discussion. Examples of some of the plants we discuss include Black Cohosh (Actaea racemosa), Fairywand (Chamaelirium luteum), Ginseng (Panax quinquefolia), Goldenseal (Hydrastis canadensis), Osha (Ligusticum spp.), Spikenards (Aralia spp.), Stoneroot (Collinsonia canadensis) and White Sage (Salvia apiana).
