Note: Goldenseal is sometimes referred to as "Indian turmeric" or "curcuma," but should not be confused with turmeric (Curcuma longa Linn.).
Goldenseal is one of the five top- selling herbal products in the United States. However, there is little scientific evidence about its safety or effectiveness. Goldenseal can be found in dietary supplements, eardrops, feminine cleansing products, cold/ flu remedies, allergy remedies, laxatives, and digestive aids.
Goldenseal is often found in combination with echinacea in treatments for upper respiratory infections and is suggested to enhance the effects of echinacea. However, the effects when these agents are combined are not scientifically proven.
Goldenseal has been used by some people due to the popular notion that detection of illegal drugs in urine may be hidden by use of the herb, although scientific information is limited in this area.
The popularity of goldenseal has led to a higher demand for the herb than growers can supply. This high demand has led to the substitution of other herbs such as Chinese goldthread (Coptis chinensis Fransch.) and Oregon grape (Mahonia aquifolium [Pursh] Nutt.), that do not contain exactly the same isoquinoline alkaloids and may not affect the body in the same way as goldenseal.
Studies of the effectiveness of goldenseal are limited to one of its main chemical ingredients, berberine salts (there are few published human studies of goldenseal itself). Due to the small amount of berberine actually present in most goldenseal preparations (0.5- 6%), it is difficult to extend the research of berberine salts to the use of goldenseal. Therefore, there is not enough scientific evidence to support the use of goldenseal in humans for any medical condition.
