Methods: 100 patients with spleen-stomach qi deficiency syndrome were selected in the hospital and randomly divided into two groups, one of which was treated by ordinary methods and the other by Sijunzi Decoction. After a period of time, check the physical conditions of the two groups of patients, and the contents are mainly divided into three aspects: The first is the clinical treatment effect of the patients, the second is the relapse of the patients, and the third is the adverse reactions of the patients. According to the comparison of the treatment results of two groups of patients, we can see the clinical application effect of Sijunzi Decoction. Results: comparing the results of the two groups of patients, it can be concluded that Sijunzi Decoction has great efficacy, which can not only improve the treatment effect of patients, but also reduce the probability of recurrence of diseases, and also has a strong inhibitory effect on adverse reactions of patients. Conclusion: through this study, it can be found that Sijunzi Decoction has a significant effect in the treatment of patients with spleen and stomach qi deficiency in internal medicine of traditional Chinese medicine, which can effectively improve the disease condition of patients. Therefore, it has a strong use value and is worthy of being widely used in the follow-up clinical treatment.展开更多
