Effect of Stevia aqueous extract on the glycosylated hemoglobin (HbA1c) level of the rats. Results are expressed as percentage of HbA1c levels of diabetic and non-diabetic rats (mean ± standard deviation (SD). n = 10). a, b, c, d represent significant difference (P < 0.05) in HbA1c levels treatment wise. HbA1c levels of diabetic rats (D1, D2, D3 and D4) received stevia aqueous extract in different concentrations (200, 300, 400 and 500 ppm) respectively significantly (P < 0.05) decreased as compared diabetic (D0) control groups and near to N0
