The clump can then be replaced in the ground the way it came out, and the remaining plants in the clump will continue to grow. Keep only roots that have identifiable seeds attached. During washing, you can double check each root. Do not use smell alone for identification. Although this root's smell is unique, other roots in the clump can pick it up.
Harvest leaves when identifiable, and seeds when green and aromatic.
Processing Wash roots thoroughly but quickly in cold water. I consider the fresh root almost edible as a food, and the fresh tincture is highly prized. The roots can also be dried for later use. As some of the constituents are only partially water soluble, it is best chewed, encapsulated, or tinctured. Native Americans peel their roots, but this is not mandatory.
