Abstract: A substance including the chemical structures of bicyclo [3.2.1]octan or the chemical structures of kaurene for the use in a dietary supplementation or as a constituent in a medicament for the treatment of non-insulin dependent diabetes mellitus, hypertension and/or the metabolic syndrome. The unique chemical structures of bicyclo [3.2.1]octan alone or in a kaurene structure provides the substances, such as e.g. steviol, isosteviol and stevioside with the capability of enhancing or potentiating the secretion of insulin in a plasma glucose dependent manner. The substances including these unique chemical structures also have the capability of reducing the glucagon concentration in the blood and/or lowering the blood pressure thereby providing a self-regulatory treatment system for non-insulin dependent diabetes mellitus and/or hypertension.
