〔Abstract〕 Objective To observe the clinical efficacy of Qufeng Anluo recipe in the treatment of allergic purpura in children with wind heat injury collateral type. Methods 70 allergic purpura children with wind heat injury collateral type admitted to the First Affiliated Hospital of Henan University of Science and Technology from January 1, 2020 to January 1, 2022 were selected and randomly divided into a control group and an observation group, with 35 cases in each group. Children in the control group were given routine symptomatic treatment, and the observation group were given Qufeng Anluo recipe orally on the basis of the control group. The changes of traditional Chinese medicine (TCM) syndrome scores and urine test scores before and after treatment were observed and compared between the two groups. Results After treatment, the total scores of TCM syndromes in the two groups decreased to different degrees, and the total scores of TCM syndromes in the observation group were lower than those in the control group, and the differences were statistically significant (P < 0.05). After treatment, the total scores of urine test in the two groups were improved to different degrees compared with that before treatment, and the differences were statistically significant (P < 0.05). After treatment, there was no significant difference in the total scores of urine test between the two groups (P > 0.05). The total effective rate of the observation group was 96.97 %, higher than 81.82 % of the control group, and the difference was statistically significant (P < 0.05). No adverse reactions occurred in the two groups during treatment. Conclusion Qufeng Anluo recipe combined with western medicine in the treatment of allergic purpura in children with wind heat collateral injury type, which is effective and good safety.
