Barberry root bark comes from the root of the Berberis vulgaris plant, a shrub native to Europe, Asia, and North Africa, and now naturalized in North America. The root bark has a bright yellow color due to the presence of berberine, an alkaloid with a long history of use in traditional herbal practices. Known for its bitter taste, barberry root bark is commonly used in teas, tinctures, and extracts.
