(a) Treatment with Jie-Yu-He-Huan capsule prevents altered behaviour in the open field test caused by chronic restraint stress. ∗p < 0.05 compared to the control group, #p < 0.05 compared to the model group, ##p < 0.01 compared to the model group, and ####p < 0.0001 compared to the model group (unpaired t-test). (b) Treatment with Jie-Yu-He-Huan capsule prevents altered behaviour in the elevated plus maze test caused by chronic restraint stress. ∗∗p < 0.01 compared to the control group, #p < 0.05 compared to the model group, and ##p < 0.01 compared to the model group (unpaired t-test). (c) Treatment with Jie-Yu-He-Huan capsule prevents altered behaviour in the light-dark box test caused by chronic restraint stress. ∗p < 0.05 compared to the control group, ∗∗∗p < 0.001 compared to the control group, #p < 0.05 compared to the model group, ##p < 0.01 compared to the model group, ###p < 0.001 compared to the model group, and ####p < 0.0001 compared to the model group (unpaired t-test).
