Goldenseal (Hydrastis canadensis L.) a member of the family Ranunculaceae, is a native American medicinal drug introduced to early settlers by Cherokee Indians, who used it as
a wash for skin disorders and sore eyes. Goldenseal extract, derived from the rhizome and roots of this small forest plant, has acquired a considerable reputation as a general bitter tonic and to support the health of the gastric and genitourinary systems.

Goldenseal's benefits can be attributed to its alkaloids, especially hydrastine and barberine. The barberine is also responsible for the herb's characteristic golden color. These alkaloids are strongly astringent and help soothe irritation mucous membranes. Hydrastine has also been reported to lower blood pressure and stimulate peristalsis, along with being an
anti-tussive (relieves coughs).

Barberine and its sulfate, barberine sulfate, have been demonstrated to have anti-bacterial, anti-fungal and immunostimulatory activity. Barberine has shown marked effects on acute diarrhea. Barberine also enhances the activity of specific white blood cells that help the body fight infection against invading organisms. Goldenseal also reportedly increases the blood flow to the spleen, which also supports immune function.

Goldenseal has been recommended to support the health of mucous membranes, including stomach, intestinal, vaginal and rectal. It has been reported that the plant relieves pains and helps heal wounds and stop bleeding. In addition, the antibacterial action helps control infection of open sores.

Too high of a dose of Goldenseal may cause nausea, vomiting, a decrease in the white blood count and feelings of pins and needles in the hands and feet.
