Overview – Goldenseal (Hydrastis Canadensis), also known as yellow root, is a potent herb with anti-inflammatory, anticatarrhal, antiseptic, antimicrobal, oxytocic, and hepatic properties. It also has astringent properties which halt mucus production. It is one of the best herbal immune system stimulants and works especially well when it is alternated throughout the day with Echinacea.

What Goldenseal Can Treat – Inflammation, HIV, Canker Sores, Fungus, Opthalmia, Infection, Digestive Problems, Diarrhea, Irregular Menstruation, Prostrate Disorders, Allergies, Uterine Bleeding, Ulcers, Periodontal Disease, Inflamed Gums, Irritable Bladder Syndrome, Bladder Disorders, Vaginal Disorders, Ear Infections, Common Cold, Flu, and Sore Throats.

How it Works – Two alkaloids are responsible for goldenseal’s effectiveness:



Hydrastine – This is a pesticide, sedative, and an antimicrobial. It is responsible for treating chronic diarrhea and pesticides.

Berberine – This is the component that is responsible for Goldenseal’s success against fungal infections, such as yeast infections, parasites, and viral infections. Research has also been frontiered that suggest that it is also effective against MRSA (Methicillin-resistant Staphylococcus aureus), a strand of superbacteria frequently found in hospitals. It has been used, through Goldenseal and other related plants such as barberry and Oregon Grape, for thousands of years and has a cultural place in Hindu and Chinese medicine. 



One study of particular interest showed that "berberine prevents HIV PI-induced inflammatory response" (Virginia Commonwealth University). This is quite a promising finding.

Treatment and Dosage - Placing a few of Goldenseal in liquid form under the tongue is a quick way to absorb it and jumpstart your body’s battle against a pathogen. This is particularly effective for coughing. It is best to do this 3 times a day. If you are taking capsules, take 1600-2000 mg 4-5 times a day. Alternate with Echinacea capsules, since it is generally best to take Goldenseal along with other herbs, alternating them, such as Echinacea, as this increases their potency. 



To treat canker sores, gargle a dropper full of goldenseal. This also works for Periodontal Disease and inflamed gums. Do this until the ailment goes away. However, do not continue internal use for more than a week since goldenseal can interfere with your stomach’s bacterial balance.

To treat infants, you can place drops of goldenseal into their milk or some plain yogurt.

Toxicity and Cautions - Always buy goldenseal with the alcohol removed. 



Do not take Goldenseal for more than 14 continuous days. Do not take Goldenseal if you have an autoimmune condition. Avoid goldenseal if you are nursing or pregnant. Those who have high blood pressure should avoid taking Goldenseal for more than 7 consecutive days.
