From the Manufacturer:
Goldenseal is often combined with Echinacea to help shorten the duration of colds and flu. Goldenseal is a perennial North American plant found in a large portion of the United States. It has been a main staple of Native American medicine with multiple uses both internally and externally. It has been called the “poor man’s ginseng.” The root, or more accurately the rhizome, of the goldenseal plant is the part most often used in medicinal applications. The herb has shown great effectiveness in treating the inflammation and infection of the mucous membranes lining the upper respiratory tract.
