History of bitter melon use
Bitter melon has long been used in Asia, Africa, and Latin America as a hypoglycemic herb and serves as a primarily alternative therapy for lowering blood glucose levels in patients with diabetes. The most common application of bitter melon is the use of extracts and powdered formulations. Less frequently used are teas made from the stems and leaves of this cucumber-like fruit. Bitter melon is also consumed as a foodstuff and can be found in many Asian markets.
Bitter melon constituents & diabetes
The main constituents of bitter melon that have reported hypoglycemic actions are the triterpenoids (like charantin) and the ribosome inactivating protein momordin.[1] Several mechanisms of action have been proposed for the hypoglycemic effects of bitter melon, including inhibition of intestinal absorption of glucose,[2] suppression of key glucogenic enzymes,[3] decreasing hepatic gluconeogenesis,[4] and increasing ß -cell production in the pancreas.”[5]
