Experimental Group A total of 36 methadone patients will receive auricular pressure

Control group 36 bits No interventions implemented

The seeds of blancia blanc were fixed on the acupoints with patches. The intervention measure in the experimental group was auricular point sticking. The two groups received four measurements before the intervention and 2 weeks, 4 weeks, and 6 weeks after the start; while the control group received no Auricular pressure.

There were significant between-group differences in Bristol Stool Type at Weeks 2, 4, and 6 between the two groups (p= .003, p < .001, p < .001, respectively). The distribution of Bristol Stool Types in the second week, the fourth week, and the sixth week of the above-mentioned auricular point sticking intervention in the two groups all had statistically significant differences.

The total score of the experimental group in the 2nd week and the 6th week was damp and hot (p < .05); the experimental group had a significant difference in the decrease of the total score of the qi stagnation in the 4th week and the 6th week (p < .05).

There was no significant difference in the scores of the Bayesian Anxiety Scale and depression between the experimental group and the control group at the 2nd week, 4th week and 6th week (p > .05).

There were significant differences in the decrease of the total score of the experimental group in the 2nd week, 4th week and 6th week (p < .05, p < .001, p < .001 respectively)
