Some embodiments of the invention do not include corosolic acid, or include it at a low concentration in combination particularly enriched in other compounds. Such extract compositions that do not contain corosolic acid, are the product of extraction process that yield controllably increased ratios of gallotannins, ellagitannins, and valoneic acid dilactone. Such compositions, both those containing corosolic acid and those lacking corosolic acid are efficacious in effecting control of blood glucose.
