The Nature's Answer Echinacea Goldenseal is made from the areal parts of Echinacea purpurea and roots of Echinacea angustifolia and Goldenseal (Hydrastis canadensis) , all native North American plants. It offers tremendous benefits of 6 mg polyphenols, 5 mg of berberine and 2.5 mg of hydrastine per serving.,. Super Concentrated with 1,000mg, Nature's Answer Echinacea Goldenseal Extract promotes a healthy immune system*. Nature's Answer alcohol-free extracts are produced using alcohol, water, and natural extractants. All alcohol and extractants are then removed through our proprietary cold Bio-Chelated extraction process, yielding a Holistically Balanced standardized extract. Liquid extracts are absorbed faster than tablets or capsules and are on average 5 times more potent than tinctures. The Holistically Balanced process guarantees that the constituents of the extract are in the same synergistic ratios as in the natural plant.
