did not reduce fasting plasma glucose or plasma glucose after
OGTT when compare with placebo (Kasbia et al., 2009). However,
the results also disagreed with the case series study of Srivastava
(1993)where dried bitter melon powder reduced FPG levels by
11–48 mg/dL and our previous retrospective study where the
mean reduction in FPG levels was 26.7 ± 40.8 mg/dL (Fuangchan
et al., 2009). This might due to difference in process to prepare
bitter melon product or difference in amount of active ingredient
which did not state in above study.
