Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)

Goldenseal was used by Native Americans as a treatment for irritations and inflammation of the mucous membranes of the respiratory, digestive, and urinary tracts. It was commonly used topically for skin and eye infections and has been used historically as a mouthwash to help heal canker sores. Because of its anti-microbial activity, goldenseal has a long history of use for infectious diarrhea, upper respiratory tract infections, and vaginal infections. Goldenseal is often recommended by herbalists in combination with echinacea for the treatment of colds and flu. Its benefits are most likely limited to helping ease the discomfort of a sore throat associated with these conditions. Goldenseal was considered a critical remedy for stomach and intestinal problems of all kinds by early 20th century Eclectic physicians (doctors who recommended herbs).1
