- Reliable and relatively consistent scientific data showing a substantial health benefit.
- Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
- For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
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)
Mullein leaves and flowers are classified in traditional herbal literature as expectorants (promotes the discharge of mucus) and demulcents (soothes irritated mucous membranes). Historically, mullein has been used by herbalists as a remedy for the respiratory tract, particularly in cases of irritating coughs with bronchial congestion.1 Some herbal texts extend the therapeutic use to pneumonia and asthma.2 Due to its mucilage content, mullein has also been used topically by herbalists as a soothing emollient for inflammatory skin conditions and burns.
