Nature's Sunshine Echinacea/Goldenseal combines two species of echinacea with goldenseal root extract. Echinacea is widely used for immune support, while goldenseal is valued for its alkaloids, especially berberine and hydrastine, and is often used where mucous membrane support is helpful. Together they make a classic herbal pairing for immune, respiratory and upper digestive support.
The extra goldenseal changes the feel of the formula compared with echinacea alone. It adds more support for the tissues lining the respiratory and digestive tracts, which is why this blend has stayed popular for years.
