The sample size was determined using the Federer formula, amounting to 5 individuals in each treatment. The results of analysis using Paired sample T-test showed a p-value of 0.000 or sig value <0.05, which means that homemade herbal powder at doses of 400, 600 and 800 mg/kg BW can reduce blood glucose levels.
