Abstract Objective Salacia oblonga , Tinospora cordifolia , Emblica offinalis Gaertn , Curcuma longa and Gymnema sylvestre are Ayurvedic medicinal plants reported to lower plasma glucose levels in animal models. To our knowledge, however, no clinical validations of those extracts for efficacy have been. The aim of this study was to evaluate the effect of polyherbal combination in patients with type 2 diabetes mellitus. Methods We screened 250 patients enrolled in a diabetes mellitus screening camp held at District Ayurvedic Hospital, Kottayam, Kerala, India. Of these, 89 patients diagnosed with type 2 diabetes mellitus and 50 healthy volunteers of similar age group were included in the study. Patients were treated with a polyherbal combination drug namely G-400 (1000 mg/d) for 8 wk with a follow-up of 2wk interval. Results Fasting and postprandial blood glucose levels measured after 8 wk of G-400 treatment in patients were significantly lower. Indeed diabetic rats showed similar protection with G-400 administration. Furthermore, glycosylated hemoglobin, serum total cholesterol, both high- and low-density lipoprotein cholesterol, and triglycerides showed a significant improvement in G-400–administered patients. Toxicologic profile of the drug was assessed by analyzing the enzyme activities of alkaline phosphatase and alanine aminotransferase along with the concentration of blood urea nitrogen and creatinine in blood and found insignificant change compared with control. Conclusion Short-term supplementation of G-400 not only attenuates the hyperglycemia, but also acts as hypolipidemic agent in patients with diabetes. Further study should be done for the long-term effect of the drug in larger populations.
