Background: The aim of the present study was to evaluate the antidiabetic potential of Manomani chooranam (MMC), an indigenous polyherbal siddha formulation in Streptozotocin (STZ) induced diabetic female Wistar albino rats.

Methods: Aqueous extract of MMC was prepared. Wistar albino rats were divided into six groups (n=6). Group 1 was kept as normal control, Group 2, 3, 4, 5 and 6 were induced diabetes. After induction, the group 2 was kept as diabetes control; Group 3 received the standard drug metformin (100 mg/kg), whereas Groups 4, 5 and 6 were treated with the aqueous extract of MMC at 500 mg/kg, 1000 mg/kg and 1250 mg/kg doses, respectively for the 21 days. Blood sugar was estimated at the end of each week. At the end of the study, rats were sacrificed and the pancreas was analyzed for histopathological changes. Data expressed as mean┬▒standard error of the mean. Statistical analysis was done using one-way ANOVA followed by post hoc Tukey's test. p<0.05 considered statistically significant.

Results: The groups which received aqueous extract of MMC at 500 mg/kg, 1000 mg/kg and 1250 mg/kg showed a significant decrease in the mean blood sugar level when compared to normal level. The groups which received MMC shows significant reduction in blood sugar level in comparison with standard drug metformin 100 mg/kg.

Conclusions: The aqueous extract of MMC was able to decrease the elevated blood sugar levels in dose dependent manner.
