Abstract: This paper points out that the congenital endowment of children with asthma is different, forming the latent constitution of "latent-wind", combined with the invasion of external evil by harmful wind, leads to the pathogenesis of asthma. It is proposed that, the middle and later stage should be increased in addition to the traditional asthma attack and remission staging methods. The "wind elimination method" in the treatment of three-stage pediatric asthma: during the attack stage, expel external wind and "latent-wind" elimination, downregulate qi, and relieve asthma; treatment methods for the middle and later stages are promoting healthy qi and suppressing "latent-wind"; during the remission period, restores organ qi and resists external wind, tonifying the lung, spleen, and kidney. This paper focuses on how to treat the three-stage asthma syndrome in children using the theory of eliminating wind; to clarify the evolution characteristics and syndrome differentiation law of the "latent-wind" in asthma syndrome. This paper provides theoretical support and implementation strategies for TCM clinical diagnosis and treatment of pediatric asthma, combining modern clinical and mechanism research progress.
