Goldenseal Supplement: Medicinal Herb of Many Uses

goldenseal supplementsA goldenseal supplement is primarily used for its positive effects on the immune system, even though it can also combat viruses and bacteria quite successfully. It is also known as a ‘natural antibiotic’ because of its ability to fight infection.

Goldenseal is a very versatile herb that is officially designated as a medicinal drug in at least 11 countries around the world. The United States has yet to list it in the medicinal category and goldenseal supplementation is relegated to the food category by the FDA.

This amazing herb has been used for centuries by Native American Indian tribes such as the Iroquois and the Cherokee.

The most important substance in this herb are hydrastine and berberine, which are alkaloids that cause a medicinal effect when used. Goldenseal’s yellow colored roots are caused by the berberine in the plant.

In fact, the color is so strong, that early American settlers actually produced yellow dye from the roots to color fabric.
