The effect of HZ extract treatment on blood glucose and insulin resistance in HFD-fed C57BL/6 J mice. a Levels of blood glucose after 12 h of fasting. b Levels of plasma insulin after 12 h of fasting. c The HOMA-IR index calculated using fasting blood glucose and insulin levels. Data are shown as means ± SEM (n = 10 per group). ND vs. HFD: *p < 0.05; **p < 0.01; ***p < 0.001. HFD vs. HZ: #p < 0.05; ##p < 0.01; ###p < 0.001
