In terms of treating chronic obstructive pulmonary disease (COPD), Wang Zai-fang, a TCM chief physician, stresses that the classification of COPD should be combined with TCM syndrome differentiation. In the remission period of COPD, deficiency of the lung, spleen and kidney, phlegm, blood stasis and ,qi, stagnation are the endogenous pathogenic factors, which run through the whole process of the occurrence and development of the disease. Professor Wang believes that the disease in the remission period is often manifested as more deficiency and less excess, with deficiency mixed with excess, which should be differentiated in detail according to the different constitution and clinical manifestations of each patient. In the early stage of COPD, the treatment should focus on nourishing the lung and strengthening the surface, dissipating phlegm and stopping cough. Jade Wind-Barrier Powder combined with Modified Lung-Supplementing Decoction can be used. In the progressive stage, it is better to invigorate the lung and spleen, dissipate phlegm and stop cough. Jade Wind-Barrier Powder combined with Four Gentlemen Decoction, and Poria and Cinnamon Twig and Atractylodes Macrocephala and Licorice Decoction can be used. With the progress of the disease, when the lung and kidney are involved, it is necessary to supplement the lung and the kidney, lower ,qi, and relieve asthma. Pulse-Engendering Powder combined with Lung-Wrinkle Decoction, and Ginseng and Gecko Powder can be used. For those with deficiency of the lung, spleen and kidney, it is necessary to invigorate the lung, strengthen the spleen, nourish the kidney and absorb ,qi, dissipate phlegm, relieve cough and asthma, Ginseng and Gecko Powder, Special Achievement Powder, and Golden Cabinet's Kidney ,Qi, Pill can be used.
