Goldenseal

Goldenseal (Hydrastis canadensis) is one of the most popular herbs in the United States, often combined with echinacea and sold to treat or prevent colds. But there is no evidence that it works. In fact, there is very little scientific evidence that goldenseal works to treat any condition.

Nevertheless, goldenseal is often said to kill bacteria and is sometimes used to treat eye infections, diarrhea, urinary tract infections, canker sores, and vaginitis. A substance in goldenseal, called berberine, does kill some kinds of bacteria and fungus in test tube studies. But scientists do not know if goldenseal would kill any germs in people.

Goldenseal is also popular because of a rumor that taking the herb can help block a positive test for illegal drugs. There is no evidence that it works, and several studies have reported that taking goldenseal does not change the results of a drug test.
