Artichoke contains bitter principles, cynarin and sesquiterpene-lactones. Scientific studies show that these compounds not just inhibit cholesterol synthesis but also increase its excretion in the bile, and thus, help overall reduction in the total cholesterol levels in the blood.
Fresh artichoke is an excellent source of vitamin, folic acid; provides about 68 µg per 100 g (17% of recommended daily allowance).
