Ping chuan-fang prescription is carefully composed accordingly. The clinical investigation shows that PCHF can not only alleviate symptoms and physical sign of the patients effectively, but also shorten the course of disease and obviously can not only alleviate symptoms and physical sign of the patients effectively, but also shorten the course of disease and obviously improve the pulmonary function of the patient. The animal experiment showed that PCHF can prolong the asthmatic time and low the concentration of WBC, EOS, IL-4, ET-1 in the blood and BALF. It can restrain the collection of EOS in the lung and relieve the inflammation caused by EOS. It also can cut down the secretion of the respiratory air-way and relieve the obstruction of it.

动物实验表明：平喘方能明显延长卵蛋白造模大鼠的引喘潜伏期，且与氨茶碱对照有非常显著性差异(P＜0.01)；能降低哮喘模型大鼠血浆及肺泡灌洗液中白细胞、嗜酸性粒细胞及IL-4、ET-1的含量；能抑制肺局部EOS的聚集，明显减轻由EOS浸润引起的慢性变应性炎症反应；能减少气道分泌物，减轻细支气管及小血管管壁的增厚，减轻周围组织的水肿，从而减轻气道的阻塞，最终改善肺通气，缓解喘息症状。
