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)
Australian Aborigines used the leaves to treat cuts and skin infections. They would crush the leaves and apply them to the affected area. Captain James Cook and his crew named the tree “tea tree,” using its leaves as a substitute for tea as well as to flavor beer. Australian soldiers participating in World War I were given tea tree oil as a disinfectant, leading to a high demand for its production.
