Objective: To determine the content of trace elements Ca, Zn, Mg, Cu, and Fe in various constituents of traditional Chinese medicine, Yijianfengyu Yupingfeng San, and the influence of trace element content in whole blood of children with recurrent respiratory infection, and to clarify its uprightness from the perspective of trace element changes. Anti-faith mechanism. Methods: The content of trace elements was determined by GGX-9 atomic absorption spectrophotometer. One hundred and sixty-six children with recurrent respiratory infections were divided into a treatment group and a control group. After one course of treatment with Yupingfeng Powder, the clinical therapeutic effect was observed and the content of trace elements in the blood was compared. RESULTS: After one course of medication, the clinical symptoms of the treatment group improved significantly (P<0.01), and the zinc, calcium, and iron contents increased significantly (P<0.01 or P<0.05). Conclusion: Yupingfeng Powder can correct the deficiency of trace elements in children with recurrent respiratory infection.
