Golden Seal [Immune] by Nature's Sunshine is native to North America. The plant has been largely overharvested and is periodically in short supply. Its immune-supporting properties are largely due to its hydrastine, berberine and canadine alkaloids. It is said to help support the mucous membranes that line the respiratory, digestive and urinary tracts. Because demand for the herb is high and supplies are low, golden seal is one of the most expensive herbs on the market. For this reason, many herb suppliers are tempted to adulterate supplies of golden seal with other herbs of similar chemical composition, such as Oregon grape. However, only golden seal contains the alkaloid hydrastine. Nature’s Sunshine boasts the technology and expertise needed to test golden seal for hydrastine--thus ensuring a pure, unadulterated supply of this valued herb. Each capsule contains 500 mg golden seal root.
