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 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.

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

Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production.1 As a result, they are particularly used when there is low stomach acid but not in heartburn (where too much stomach acid could initially exacerbate the situation). These herbs literally taste bitter. Some examples of bitter herbs include greater celandine , wormwood , gentian, dandelion , blessed thistle , yarrow , devil’s claw , bitter orange, bitter melon , juniper , andrographis , prickly ash , and centaury .2. Bitters are generally taken either by mixing 1–3 ml tincture into water and sipping slowly 10–30 minutes before eating, or by making tea, which is also sipped slowly before eating.

Some bitters widely used in traditional medicine in North America include yarrow , yellow dock , goldenseal , Oregon grape , and vervain . Oregon grape’s European cousin barberry has also traditionally been used as a bitter. Animal studies indicate that yarrow, barberry, and Oregon grape, in addition to stimulating digestion like other bitters, may relieve spasms in the intestinal tract.3

Traditional Use (May Not Be Supported by Scientific Studies)

Yellow dock has a long history of use as an alterative. Alterative herbs have nonspecific effects on the gastrointestinal tract and the liver. As a result, they are thought to treat skin conditions attributed to toxic metabolites from poor digestion and poor liver function.

How It Works

Common names:
Rumex
Botanical names:
Rumex crispus

How It Works

Yellow dock contains relatively small amounts of anthraquinone glycosides, which may contribute to its mild laxative effect.4 It is also thought to stimulate bile production. It is often used as a digestive bitter for people with poor digestion. No human studies have been done on its use as medicine.

How to Use It

A tincture of yellow dock, 1/4–1/2 teaspoon (1–2 ml) three times per day, can be used.5 Alternatively, a tea can be made by boiling 1–2 teaspoons (5–10 grams) of root in 2 cups (500 ml) of water for ten minutes. Three cups (750 ml) may be drunk each day.
