FIGURE 5.

The effect of rikkunshito (RKT, ghrelin enhancer) on food intake. The effect of the endogenous ghrelin enhancer RKT at a dose of 1000 mg·kg⁻¹ in stressed mice was evaluated, and 1‐h cumulative food intake was measured after RKT administration. Three mice were excluded due to an obvious researcher's technical mistake. Male control: n = 7 (excluded: 1); male stress: n = 7 (excluded: 2); male stress + RKT: n = 9; female control: n = 8; female‐other groups: n = 9. Results are shown as means ± SEM. *P < 0.05 vs. control; ^† P < 0.05 vs. stress in two‐way ANOVA followed by the Tukey–Kramer post hoc test
