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.
1 StarFor an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Indigestion, Heartburn, and Low Stomach Acidity
Refer to label instructions
Centaury acts as a digestive stimulant and may be helpful for indigestion.
Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production.2 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.3. 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.
Traditional Use (May Not Be Supported by Scientific Studies)
Centaury is one of the mainstays of European folk herbalism as a tonic for the digestive tract.1 It was also used as a general tonic for people who had fevers.
How It Works
How It Works
Centaury contains bitter glycosides that stimulate secretion of stomach acid and digestive enzymes as well as activity of the entire digestive tract.4 Centaury is recommended by the German Commission E for people with poor appetite and indigestion.5 One preliminary animal study showed the herb had anti-inflammatory and fever-lowering effects.6
How to Use It
Centaury is generally taken prior to a meal. A tea is made by adding 1 to 2 teaspoons of the herb to one cup of hot water and allowing it to steep for 15 minutes.7 The tea should be sipped slowly. The bitter taste can be covered up by adding ginger tea. Alternately, capsules can be used in the amount of 1 to 2 grams three times per day before a meal.8
