Experience in Treating Children Chronic Cough based on the Theory of Healthy Qi Deficiency and Pathogenic Qi Retention
The main pathogenesis of chronic cough in children is the disorder of ascending and descending of qi movement caused by healthy qi deficiency and pathogenic qi retention.The deficiency of lung,spleen,and kidney is the root of the disease,and the retention of phlegm-fluid,food accumulation,and fire from constraint is the branch pathogenesis of the disease.In the treatment,we should reinforce and tonify healthy qi,dispel pathogen and regulate qi,with Yupingfeng Powder(玉屏风散)as the basic prescription.For lung qi deficiency syndrome,modified Yupingfeng Powder could be used for supplementing lung to consolidate the exterior;for lung and spleen qi deficiency syndrome,modified Yupingfeng Powder plus Shenling Baizhu Powder(参苓白术散)could be used for supplementing lung and fortifying the spleen,treating with both supplementation and transformation;for lung kidney qi deficiency syndrome,modified Yupingfeng Powder combined with Suzi Jiangqi Decoction(苏子降气汤)could be used for supplementing lung and replenishing kidneys,absorbing qi to the root.All the above prescriptions could combine the method of dis-pelling phlegm,promoting digestion and guiding out food stagnation,soothing the liver and draining fire to remove the solid pathogens,in order to treat the root and branch simultaneously,and the cough will stop if the ascending and de-scending of qi movement recover as usual.
