In the treatment group, oral administration of Trichosanthes root 1.5 g, bid/day for 84 days continuously; in the control group, oral administration of Trichosanthes root placebo 1.5 g, bid/day for 84 days continuously. The main outcome measure was the changes of plasma blood sugar and Glycated hemoglobin A1c (HbA1c) levels changed before and after Trichosanthes root treatment.
