BACKGROUND Makaradhwaja a gold containing mercurial preparation used for diabetes mellitus in indigenous system of medicine. It is a popular aphrodisiac and rejuvenator traditional medicine. It is prepared by using processed gold, mercury and sulfur in different ratios by applying intermittent heating pattern in Valuka Yantra. OBJECTIVES The aim of the study was to evaluate anti-diabetic effect of Shadguna Balijarita Makaradhwaja (SBM) on streptozotocin (STZ) induced diabetic rats. MATERIALS AND METHODS Diabetes was induced to normal rats by injecting STZ in dose 40 mg/kg. Powdered SBM and dried extract of Tinospora cordifolia were mixed with honey and administered orally for 20 days at dose 2.63 mg/kg and 42.34 mg/kg body weight, respectively. The effects of treatment on body weight changes and blood glucose levels were quantified on day 1, 5, 10, 15 and 21 of the experiments. On the 21(st) day, animals were sacrificed and gross histopathological changes in liver, kidney and pancreas were illustrated. Blood sugar level, glyacated hemoglobin, blood urea, serum cholesterol, serum creatinine, serum triglyceride and serum protein were estimated with standard methods. The study was conducted in the year 2011. RESULTS Test drug observed significant decrease (P < 0.001) in glyacated hemoglobin level compared to diabetic control rats. Blood sugar level of test drug group shown a significant decrease (279.11 ± 57.95) compared with diabetic rats. CONCLUSION The present study demonstrates that SBM and dried extract of T. cordifolia with honey significantly reduces the blood glucose level and shows anti-diabetic effect.
