Cholesterol
There have been numerous studies of artichoke leaf extract ever since European scientists first discovered cynarin's ability to lower cholesterol in the 1970's. Caffeoylquinic acids, such as cynarin are the active ingredients in artichokes that lower cholesterol, with higher concentrations in the leaves. A 6 week double blind, placebo controlled clinical trial of 143 patients has demonstrated without a doubt to the effectiveness of artichoke leaf extract for lowering cholesterol.

Hangovers
Contrary to what some would like to believe, a study demonstrated the ineffectiveness of artichoke extract in the cure of alcohol-induced hangovers.

Diabetes
The carbohydrate in artichokes is in the form of inulin, which has been shown to stabilize blood sugar levels in diabetics.
