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)
Horehound was reportedly first used in ancient Rome by the physician Galen, who recommended it as a therapy for coughs and other respiratory ailments. Like Galen, Nicholas Culpeper, the 17th-century English pharmacist, commented that it was helpful for a cough and was also useful in helping remove stubborn phlegm from the lung. Similarly, American Eclectic physicians (doctors who recommended herbs) of the 19th century remarked on its value as a medicinal plant not only for coughs and asthma but also in menstrual complaints.2
