Antihyperglycemic effect of water extract of dry fruits ofTerminalia chebula in experimental diabetes mellitus

摘要

Water extract of dry fruits ofTerminalia chebula (Hindi-Harda, Telugu-Karakkaya) at a dose of 200 mg/kg body weight improved the glucose tolerance as indicated by 44% of reduction in the peak blood glucose at 2nd hour in glucose tolerance test in diabetic (streptozotocin induced) rats. Treatment of diabetic rats with an initial fasting blood glucose of 253±9.4 mg/dl daily once with the water extract (200 mg/kg) for two weeks brought down the fasting blood glucose to 123±8.4 mg/dl which is only slightly above the normal value. These results indicate that water extract of Terminalia chebula improves glucose tolerance and brings down fasting blood glucose in diabetic rats.
