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)
Wormwood is perhaps best known because of the use of its oil to prepare certain alcoholic beverages, most notably vermouth and absinthe. Absinthe, popular in the 19th century in Europe, caused several cases of brain damage and even death and was banned in most places in the early 20th century.1 Wormwood oil continues to be used as a flavoring agent for foods, although in much smaller amounts than were found in absinthe.
As a traditional medicine, wormwood was used by herbalists as a bitter to improve digestion, to fight worm infestations, and to stimulate menstruation.2 It was also regarded as a useful remedy for liver and gallbladder problems.
