Tall Oregon grape bears a cluster of bright yellow flowers in the spring, which are lightly scented. The flowers ripen into round, dusty blue-black berries, resembling grapes, by early fall. The berries are edible and seedy, though sour.
Indigenous Peoples have used preparations from Oregon grape roots to treat stomach problems, hemorrhages, arthritis, and tuberculosis. Western medicinal uses for berberine (a compound derived from the plants) include blood sugar stabilization, and studies show that it kills amoebae and can be used to treat giardia infections. ~ Additional Information
