Abstract The antidiabetic activity of an extract from the leaves of Lagerstroemia speciosa standardized to 1\% corosolic acid (Glucosol) has been demonstrated in a randomized clinical trial involving Type II diabetics (non-insulin-dependent diabetes mellitus, NIDDM). Subjects received a daily oral dose of Glucosol and blood glucose levels were measured. Glucosol at daily dosages of 32 and 48mg for 2 weeks showed a significant reduction in the blood glucose levels. Glucosol in a soft gel capsule formulation showed a 30\% decrease in blood glucose levels compared to a 20\% drop seen with dry-powder filled hard gelatin capsule formulation (P<0.001), suggesting that the soft gel formulation has a better bioavailability than a dry-powder formulation.
