The Chinese medical name for chronic obstructive pulmonary disease is asthma. It is caused by external attack, improper diet, emotional and mental disorders, and prolonged illness and exertion, resulting in loss of lung circulation and descent, upward rebellion of lung qi, or malfunction of lung and kidney output, resulting in difficulty in breathing, nasal agitation, opening of mouth and lifting of shoulders, and even inability to lie down. The lesions are mainly in the lung and kidney, and are related to the liver, spleen and heart. There is a difference between deficiency and reality in the nature of the disease. Real asthma is in the lung, which is caused by external evil, phlegm, liver stagnation, and Qi rebellion that stagnates the lung qi, resulting in unfavorable catharsis. Deficient asthma is caused by deficiency of Qi and Yin in the lungs and kidneys, resulting in abnormal output of the lungs and kidneys. In the severe stage of the disease, the disease may affect the heart, when the lungs and kidneys are both deficient, the lungs are deficient in generating Qi, and the kidneys are deficient in warming the heart Yang, resulting in exhaustion of the heart Qi and heart Yang, weakness of the blood vessels, and stagnation of blood flow, which may cause the face, lips, tongue, and nails to be blue and purple, shortness of breath and sweating, and even critical conditions such as cold limbs and loss of consciousness.
