Although goldenseal is a herbal remedy with many purported uses like detoxification, there is no evidence that goldenseal is effective for masking or detoxification purposes of illicit drugs for a drug test, reports WebMD. Similarly, there are many conditions that goldenseal is used for in folk medicine such as colds, eye infections, respiratory tract infection, canker sores and vaginitis. However, there is no scientific evidence that supports these claims, states the National Center for Complementary and Integrative Health.
The scientific name for goldenseal is Hydrastis canadensis. This plant has a substance called berberine that may be effective in destroying certain types of bacteria, according to the University of Maryland Medical Center.
The roots of this plant is dried and utilized in various forms that include pill, tablets, liquid and capsules. It is most often sold in combination with another plant called Echinacea for the treatment of colds. Some other purported uses for this herbal remedy are constipation and digestive problems.
