Goldenseal provides traditional support for the respiratory and gastrointestinal systems. Considered to be very drying to the mucus membranes, it can be helpful for allergies for this reason. It is a source of the alkaloid berberine which is being studied for many different applications. Each capsule contains 250mg Organic Goldenseal Root powder. Take 1 cap, 1 3 times per day or more often when in need, or as directed by a health care professional.
