Although goldenseal root is one of the most popular herbs sold today, it is taken almost entirely for the wrong reasons. Originally, it was used by Native Americans both as a dye and as a treatment for skin disorders, digestive problems, liver disease, diarrhea, and eye irritations. European settlers learned of the herb from the Iroquois and other tribes and quickly adopted goldenseal as a part of early colonial medical care.
In the early 1800s, an herbalist named Samuel Thompson created a wildly popular system of medicine that swept the country. Thompson spoke of goldenseal as a nearly magical cure for many conditions. His evangelism led to a dramatic upsurge in demand, followed by over-collection and decimation of the wild plant. Prices skyrocketed and then collapsed when Thompsonianism faded away.
Goldenseal has passed through several more booms and busts. Today, it is again in great demand, but now it is under intentional cultivation.
What Is Goldenseal Used for Today?
Ironically, goldenseal’s most common uses are entirely inappropriate. Goldenseal is frequently combined with the herb echinacea to be taken as a "traditional immune booster" and "antibiotic" for the prevention and treatment of colds. However, there are three things wrong with this packaging:
- There is no credible evidence that goldenseal increases immunity. Only one study weakly hints at an immune strengthening effect. 19
- Colds are caused by viruses and viruses don't respond to antibiotics.
- Goldenseal was never used traditionally for the common cold.
The other myth that has helped drive the sales of goldenseal is the widespread street belief that it can block a positive drug screen. The origin of this false idea dates back to a work of fiction published in 1900 by a pharmacist and author named John Uri Lloyd. In Stringtown on the Pike , a dead man is found to have traces of goldenseal in his stomach. In fact, he had taken goldenseal regularly as a digestive aid, but a toxicology expert mistakes the goldenseal for strychnine, and deduces intentional murder.
This work of fiction sufficed to create a folkloric connection between goldenseal and drug testing. Although the goldenseal in the story actually made a drug test come out falsely positive, this has been turned around to become a belief that goldenseal can make urine drug screens come out negative. A word to the wise: it doesn't work.
When used as a topical treatment for minor skin wounds , a sufficient quantity of goldenseal cream, ointment, or powder should be applied to cover the wound. Make sure to clean the wound at least once a day to prevent goldenseal particles from being trapped in the healing tissues.
For mouth sores and sore throats, goldenseal tincture is swished or gargled. Goldenseal may also be used as strong tea for this purpose, made by boiling 0.5 to 1 g in a cup of water. The herb has a bitter taste. Goldenseal tea is also used as a douche for vaginal yeast infections .
Although there are no reports of severe adverse effects attributable to use of goldenseal, this herb has not undergone much safety testing.
