Abstract: Children are not fully developed in physical shape and qi,and their defence function is weak.When the exogenous evil invades,the lungs are the first to be attacked. Lungs are very likely to be affected by cold or heat,so they are easily damaged and the damage may linger and it is difficult to be managed.Comprehensive Theory on Deficiency and Excess of Essential Questions states that "The diseases of five Zang result from the blocking of six Fu".This article combs Prof.Wang Xuefeng′s experience in treating asthma of pneumonia based on the theory of "To treat diseases of Zang through managing Fu". First,the origin of the theory of "To treat diseases of Zang through managing Fu"（the Theory） is elaborated form the association between physiology and pathology of Zang and those of Fu.Then,based on the pathophysiological features of children,the pathogenic key to the Theory in the development of asthma of pneumonia is that the heat in lungs spreads to the large intestine.Finally,the treatment principles are summarized by further explaining the feasibility of the Theory based on modern researches.The basic principle in the treatment is "Taking away the firewood from under the cauldron",meaning to treat the diseases by managing the root causes,that is,to clear lungs and phlegm and to stop cough and asthma.According to the stool of children,the children′s bowel movement is kept smooth by unblocking Fu in order to expel the evil.By way of treating the diseases of Zang through managing Fu,the Zang and Fu are in good state,the disease course is shortened,and the therapeutic effect is improved,in which way the diseases are prevented form becoming critical.Here a case is provided for verification.
