What Are Star Ratings?

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.

3 StarsReliable and relatively consistent scientific data showing a substantial health benefit.

2 StarsContradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

Traditional Use (May Not Be Supported by Scientific Studies)

Ancient Chinese medical texts dating from around 150 B.C. suggest the use of sweet Annie for people with hemorrhoids.¹ Other writings from 340 A.D. are the first known to mention sweet Annie as a treatment for people with fevers.² It has been used ever since for a variety of infections in Traditional Chinese Medicine.

How It Works

Botanical names:

Artemisia annua

How It Works

Artemisinin, called qinghaosu in China where it was first discovered, is thought to account for the antimalarial activity of the plant.³^{, 4} This compound is a sesquiterpene lactone and is believed to cause damage to the organisms that cause malaria inside the red blood cells they infect. Preliminary and double-blind trials, have shown that injections or oral use of artemisinin or similar compounds rapidly and effectively cure people with malaria.⁵ A human trial has also found that artemisinin reduced mortality due to malaria by 50% compared with treatment with a standard quinoline anti-malarial drug.⁶ Artemisinin-based drugs have not been studied for prevention of malaria. Test tube studies suggest artemisinin can kill other parasites and bacteria,⁷ possibly supporting the traditional notion of using it for parasitic infections of the gastrointestinal tract.

How to Use It

Artemisinin-based drugs are not readily available in the United States or Europe and are still considered experimental. Sweet Annie cannot be substituted for artemisinin as a drug and cannot be used to treat people with malaria, a potentially lethal disease requiring immediate treatment. Traditionally, 3 grams of the powdered herb was taken each day.⁸
