Results The applicability questionnaire scores were mainly concentrated at 5 points and 6 points, with 6 points being the majority, and the standard approval rate was 100%. In the appraisal evaluation, the disease, syndrome diagnosis and syndrome diagnosis scores were mostly scored by 6 points, the efficacy evaluation index conformity scores were concentrated at 5 and 6 points, and the standard overall score was 6 points. The clinical efficacy of 70 children with asthma(onset) was 95% in the Western medicine group and 98% in the Chinese medicine group. The difference between the two groups was P<0.05. The difference was statistically significant.
