What Are "Star" Ratings?

a7_3star Reliable and relatively consistent scientific data showing a substantial health benefit.

a7_2star Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.

a7_1star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

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.

This supplement has been used in connection with the following health conditions:

3 stars Indigestion, Heartburn, and Low Stomach Acidity

500 to 1,000 mg cynarin in a standardized herbal extract three times per day

Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production.3 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.4. 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.

Artichoke, in addition to being an edible plant, is a mild bitter. Extracts of artichoke have been repeatedly shown in double-blind research to be beneficial for people with indigestion.5 Artichoke is particularly useful when the problem is lack of bile production by the liver.6 Extracts providing 500–1,000 mg per day of cynarin, the main active constituent of artichoke, are recommended by doctors.

High Cholesterol

2 stars Artichoke has moderately lowered cholesterol and triglycerides in some trials.

2 stars High Cholesterol

Read details for more information

Artichoke has moderately lowered cholesterol and triglycerides in some,7, 8 but not all,9 human trials. One double-blind trial found that 900 mg of artichoke extract per day significantly lowered serum cholesterol and LDL cholesterol but did not decrease triglycerides or raise HDL cholesterol.10 Cholesterol-lowering effects occurred when using 320 mg of standardized leaf extract taken two to three times per day for at least six weeks.


Used for AmountWhy
Irritable Bowel Syndrome
Refer to label instructions 1 star In a preliminary study of people with irritable bowel syndrome who took an artichoke leaf extract daily for two months, 26% reported an improvement in symptoms.

1 star Irritable Bowel Syndrome

In a preliminary study of people with irritable bowel syndrome who took an artichoke leaf extract daily for two months, 26% reported an improvement in symptoms.11 Because no placebo group was used in this study and because irritable bowel syndrome has a high rate of response to placebo, additional research is needed to confirm this report. The amount of artichoke leaf used in the study was 320 or 640 mg per day of a 1:5 standardized extract.

Traditional Use (May Not Be Supported by Scientific Studies)

The artichoke is one of the world’s oldest medicinal plants. The ancient Egyptians placed great value on the plant—it is clearly seen in drawings involving fertility and sacrifice. Moreover, this plant was used by the ancient Greeks and Romans as a digestive aid. In 16th century Europe, the artichoke was favored as a food by royalty.

About this treatment

Common names:
Globe Artichoke
Botanical names:
Cynara scolymus

How It Works

Artichoke leaves contain a wide number of active constituents, including cynarin, 1,3 dicaffeoylquinic acid, 3-caffeoylquinic acid, and scolymoside. The choleretic (bile stimulating) action of the plant has been well documented in a controlled trial involving a small sample of healthy volunteers. After the administration of 1.92 grams of standardized artichoke extract directly into the duodenum, liver bile flow increased significantly. This choleretic effect has led to the popular use of artichoke extract in Europe for the treatment of mild indigestion—particularly following a meal high in fat. In an uncontrolled clinical trial with 553 people suffering from non-specific digestive disorders (including indigestion), 320–640 mg of a standardized artichoke extract taken three times per day was found to reduce nausea, abdominal pain, constipation, and flatulence in over 70% of the study participants.

The standardized extract has also been used to treat high cholesterol and triglycerides. In one preliminary trial and one controlled trial, use of a standardized artichoke extract was found to lower cholesterol and triglycerides significantly when taken in amounts ranging from 900 to 1,920 mg per day. One preliminary trial failed to find any effect.

While scientists are not certain how artichoke leaves lower cholesterol, test tube studies have suggested that the action may be due to an inhibition of cholesterol synthesis and/or the increased elimination of cholesterol because of the plant’s choleretic action. In test tube studies, the flavonoids from the artichoke (e.g., luteolin) have been shown to prevent LDL-cholesterol oxidation—an effect that may reduce risk of atherosclerosis.

How to Use It

The suggested adult amount of the standardized leaf extract is 300–640 mg three times daily for a minimum of six weeks. Alternatively, if a standardized extract is not available, the amount of the crude, dried leaves is 1–4 grams, three times a day.
