Goldenseal has become a popular herbal supplement to prevent and treat the common cold and the flu. Generally, it is combined with Echinacea to build up the immune system; however it is an effective treatment for many health conditions on its own. Goldenseal is also known for treating various infections, especially when combined with other herbs.
History of the Goldenseal Plant
Goldenseal was originally introduced to North American settlers by the Native Americans who used it mainly to treat digestive disorders, skin problems, wounds and eye infections. By the 1800s, goldenseal was used for a variety of illnesses and in the late 1900s it became such a popular herbal remedy that the goldenseal plant is now considered endangered in several U.S. states. The goldenseal that is sold in supplement form today is grown on farms.
The wild goldenseal plant grows in shady areas where there is rich, moist soil. The plant has a single, hairy stem with two five-point leaves as well as a raspberry-looking berry and small, white flowers. The root is the part of the plant that is used for medicinal purposes. It is yellow-brown in color, large and twisted. Most herbalists grow their own goldenseal today if they prefer it fresh as it is endangered in many states. See the USDA site for the list of states where it is endangered.
How Goldenseal Fights Bacteria and Infection
Goldenseal root contains three types of alkaloids, berberine, hydrastine and canadine, which are the main active ingredients for fighting bacteria and infections. Berberine has been proven to kill many varieties of bacteria, parasites and fungi in test-tube studies. According to the University of Maryland Medical Center, berberine in goldenseal also helps to build up white blood cells to fight off infections and build up the immune system. Goldenseal is considered to be a natural antibiotic, and is sometimes combined with other herbs, like Echinacea, for a stronger immune system booster.
Goldenseal is also known for its ability to control the mucus membranes in the body to ward off infection. It works effectively in the sinuses, respiratory tract, digestive tract, urinary tract and vagina because it can alter the action of the mucus membranes. The herb seems to know when the body needs mucus buildup to protect against infection and when to dry up mucus when there is too much. This is why it is effective as a cold, flu and allergy medicine as well as for combating respiratory infections, sore throats, bronchitis, colitis, urinary tract infections and vaginitis.
Forms of Goldenseal Available
Goldenseal can be purchased in capsule, tablet, extract and tincture form. It is also available as a tea, useful for sore throats. Goldenseal can also be found in some mouthwash mixtures to help alleviate mouth sores, thrush or sore throat. Creams and lotions that contain goldenseal are also available for treating external skin problems.
How to Use Goldenseal Effectively
For the common cold, flu and allergies, Mark Stengler, ND, author of The Natural Physician’s Healing Therapies, suggests waiting a day or two before using goldenseal in order to let mucus flow freely. After that, take one to two 500 milligram capsules of goldenseal for about two weeks to help prevent infection and dry up excess mucus.
For sinusitis, it is recommended to take a combination of Echinacea and Goldenseal for 2 to 3 weeks. The recommended dose of goldenseal is one to four 500 milligram capsules spread throughout the day. If it doesn’t clear up in that time, see a doctor.
Goldenseal can be used externally for eye infections. Mix ½ teaspoon of goldenseal root power with one cup of sterile water or saline and strain before washing out the eye. Use several drops, several times a day. If the solution becomes cloudy, toss out and make a new batch.
Goldenseal has been found effective in treating vaginal yeast infections, vaginal infections and urinary tract infections (UTIs). Stengler suggests combining goldenseal with Echinacea, uva ursi, horsetail and marshmallow for UTIs. Take 500 milligrams of goldenseal 2 to 4 times per day for up to two weeks. If the infection shows no sign of getting better in a day or two, or if symptoms such as backache, dizziness or vomiting occur, see a doctor immediately. Always see a doctor first if infection is severe.
Goldenseal Side-Effects
Goldenseal becomes toxic if used for very long periods of time. Women who are pregnant or breastfeeding should not use goldenseal. People who are taking antibiotics, blood pressure medication, blood thinners, or who have heart disease or liver disease should not take goldenseal. Always talk to a doctor before trying goldenseal, or any herbal remedy.
Goldenseal is a powerful herbal remedy and can be used for a variety of illnesses. It is available in many forms, but should not be used for long periods of time. Even though goldenseal has been shown in tests to be effective for many types of infections, it is always best to talk to a doctor first before self-treating.
