Goldenseal

Goldenseal (Hydrastis canadensis) is a stalwart of any western herbalist's dispensary. It is a broad spectrum anti-microbial herb due largely to the presence of an alkaloid called berberine. As such it can be used for amoebic, bacterial, fungal and viral infections of the gastro-intestinal, upper respiratory and genitourinary tracts. It is also astringent and healing to the mucous membranes adding extra benefit to the recovery process in these parts of the body.

Berberine is a bitter compound, along with another alkaloid called hydrastine, meaning it has a raft of complementary actions on the gastrointestinal tract. These include stimulation of appetite, improving bile flow, reducing food sensitivities, increasing the secretion of digestive enzymes and regulating insulin and glucagon secretion from the pancreas.

In times of infection Goldenseal is best combined with immune stimulating herbs and herbs specific to the symptoms and area of the body. For example a gasto-intestinal infection may also be treated with herbs that reduce diarrhoea and cramping. Goldenseal should be avoided in pregnant women due to it's stimulating action on the uterus.
