Scientists at the Agricultural Research Service have found polyphenolic polymer compounds from cinnamon bark that could become natural ingredients in products aimed at lowering blood sugar levels. Recent studies demonstrate that water-soluble polymeric compounds isolated from cinnamon have insulin-enhancing biological activity in the in vitro assay measuring the insulindependent effects on glucose metabolism and also function as antioxidants. Cinnamaldehyde is the main constituent of oils of cassia, cinnamon barks and roots.
