According to a study published by "Journal of ethnopharmacology", Leucas cephalotes (Roth.) Spreng. (Laminaceae) is an ayurvedic traditional medicinal plant used in India, Nepal and Pakistan to treat several ailments including diabetes. The ethanol extract of leaves of Leucas cephalotes was administered at doses of 150, 300 and 450 mg kg(-1)bw to diabetes induced (IDDM and NIDDM) rats. All 3 doses of the extract decreased plasma glucose and lipid profiles while improving the antioxidant status of both types of diabetic rats. Of the 3 doses used, the 450 mg kg(-1)bw dose was found to be more potent in its effects comparable to those of glibenclamide and metformin. Leucas cephalotes regulates both carbohydrate and lipid metabolism and improves body antioxidant defense systems in both types of diabetes.
