The plants, fungi, and lichen of the Pacific Northwest are important and often overlooked healing agents. This course will touch on well-known Northwest natives such as Oplopanax horridum (devil’s club), Berberis aquifolium (Oregon grape), and Usnea longissima (old man’s beard). Some regional alternatives to better known species (such as Thuja plicata or red cedar to substitute for Thuja occidentalis or arbor vitae, or Valeriana sitchensis for Valeriana officinalis) will be presented. Many less well-known local species including Arbutus menziesii (madrone), Pedicularis bracteosa (lousewort), Heracleum lanatum (cow parsnip), Balsamorhiza sagittata (bigleaf balsamroot), Lobaria pulmonaria (lungwort lichen), Polypodium glycyrrhiza (licorice fern), Asarum caudatum (wild ginger), Dicentra formosa (Pacific bleeding heart), Ligusticum grayi (Gray’s lovage), Vaccinium spp (huckleberry), Lonicera involucrata (black twinberry), Ledum groenlandicum (Labrador tea), Populus balsamifera (black cottonwood), Taxus brevifolia (Pacific yew), Abies lasiocarpa (subalpine fir), and Pseudotsuga menziesii (Douglas fir) will be discussed. In all cases clinical uses, sustainability, and safety will be included with specific case examples from Dr. Yarnell’s practice.
