What is artichoke, and what is it used for?

Artichoke is a plant, Cynara scolymus, native to the Mediterranean region. Artichoke is commonly consumed as a vegetable and artichoke extract made from the leaf, stem and root is used for medicinal purposes to treat indigestion, lower cholesterol and to protect the liver. Artichoke leaf extract is available over the counter (OTC) as an herbal supplement in the U.S.

The beneficial effects of artichoke may be from the compounds it contains, including cynarin, chlorogenic acid, caffeic acid and flavonoids. These compounds have antioxidant properties and neutralize free radicals (reactive oxygen species) that can damage tissue. In addition, artichoke extract may improve secretion and flow of bile fluid, improving digestion, reduce synthesis of cholesterol and protect the liver from fat accumulation.

Studies have shown evidence of a significant reduction in blood levels of liver enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST), total and low-density lipoprotein (LDL) cholesterol, and blood sugar in people who received artichoke leaf extract for two months. Artichoke leaf extract possibly reduces blood fats and may improve liver function and digestion, however, there is inadequate scientific evidence for most of its other purported benefits.

Suggested uses of artichoke include:


  • Do not take artichoke extract if you are hypersensitive to the aster family of plants including daisies, chrysanthemums, marigolds and ragweed.
