Osha Root (Ligusticum porter) is a mountain growing herb of the Apiaceae, or parsley family. The osha flowering plants grow in the upper parts of the subalpine zone throughout much of the mountainous regions in western North America. They are characterized by their small, fern-like leaf patterns and flower stalks that can grow up to 6 feet tall.
Osha root has been used by Native Americans for centuries as both a medicinal herb and minor food source. Described as having a peppery, celery flavor, dried osha root can be eaten directly in both whole and powdered forms. Osha root can also be brewed into a tea, or a decoction to extract its beneficial properties.
