Background: Rosella tea (Hibiscuss sabdariffa. Linn) with stevia sweetener (Stevia rebaudiana Bertoni) is a combined herbal drink that is expected to have antidiabetic effect by lowering glucose levels in people with diabetes and prediabetes. This research investigates the effect of rosella-stevia tea to decrease fasting blood glucose (FBG) and 2hours postprandial blood glucose (2-hour postprandial BG) level in prediabetic women.Method: This is quasi-experimental research with control and treatment (rosella-stevia tea) group. Each group consists of 12 prediabetic women aged 30-60years. Rosella-stevia tea (5g rosella powder, 125mg stevia sweetener) was administered to the treatment group twice a day for 14days.Result: Rosella-stevia tea consumption affects blood glucose levels. Rosella-stevia tea consumption significantly lowered the FBG level (from 111.25 7.20mg/dL to 88.58 +/- 13.19mg/dL; p < 0.01) but not the 2-hour postprandial BG level (from 123.25 +/- 37.61mg/dL to 106.92 +/- 18.82mg/dL). There are no significant differences in the control group (FBG level from 106.00 +/- 5.27mg/dL to 102.08 +/- 8.36, and 2-hour postprandial BG level from 119.83 +/- 16.43mg/dL to 128.00 +/- 23.54mg/dL).Conclusion: Rosella-stevia tea consumption can lower the FBG level but not the 2-hour postprandial BG level in prediabetic women.
