Effects of aqueous extreact of N. arbor-tristis flowers or control (DW) on fasting blood glucose levels of normal mice. Mice treated either with AFE of N. arbor-tristis at 250 mg/kg (□), 500 mg/kg (∆), 750 mg/kg (□) or DW (–). Glucose concentration (mg/dl) were measured prior to treatment and 1 h, 4 h post-treatment. Results are expressed as mean ± SEM; **P < 0.01
