This study investigated the efficacy of macelignan and hot water with Chinese traditional herb (CTH) extract on altering severe diabetic conditions in C57BL/KsJ-db/db mice. Previously, the anti-diabetic effects of macelignan were partly reported as a PPAR $\alpha/\gamma$-dual agonist. Here, we futher studied whether a combination of macelignan and CTH had more beneficial effects or not. The macelignan and CTH compound significantly decreased fasting blood glucose and HbA1c compared to macelignan-treated mice, and also significantly improved postprandial glucose, insulin sensitivity, and plasma lipid profiles (FFA, and TG). On the other hand, insulin levels were not significantly changed compared to the diabetic control group. There were no significant changes in the concentrations of total cholesterol and HDL-cholesterol, but there were changes in HTR and AI. These results suggest that the macelignan and CTH compound ameliorates hyperglycemia and efficiently improves postprandial glucose, insulin sensitivity, and hyperlipidemia compared with macelignan in db/db mice. Moreover, the macelignan and CTH compound seems to be more potent in affecting diabetic complications than macelignan.
