Growing, Harvesting and Sustainable Sourcing of Medicinal Plants

WHS233

In this 3-part weekend course, students learn about growing, harvesting (including wild harvesting if applicable to region) and sustainable sourcing of medicinal plants. As the field of Herbal Medicine is growing and expanding, concerns regarding ethics of sourcing our plants is imperative for continued survival of our medicinal plants. This course focuses on plants that can grow in the bioregion of Vancouver Island plus plants in the Pacific Northwest bioregion for wild harvesting. Discussions consist of at-risk plants from the United Plant Savers list, Development of Good Wild Crafting Practices, land access, and social movements towards sustainable transparent sourcing. The course includes in-class theoretical lectures and discussions, fieldwork for practical methodology, and take-home readings. This course relies heavily on field trips including plant identification and growing at the People’s Apothecary, Krista’s permaculture herb garden, and in the forest. Students must be prepared to attend field trips in all weather conditions.
