Comparison of weight gain in each group at the end of the experiment ($\overline{x}\pm s$,n = 8). The weight gain at the end of the experiment was shown Fig. 1.The low-dose, medium-dose, and high-dose groups were daily aromatherapy, and the daily concentration of low, medium, and high doses of Compound Anshen essential oil (CEO) was 1 × 10^− 3, 2 × 10^− 3,4 × 10^− 3 for 7 consecutive days. Note: compared with control group, ^ΔP<0.05,^ΔΔP<0.01,compared with model group,^*P<0.05,^**P<0.01
