Chinese medicine believes that there are many causes of cough and asthma, but the treatment should first be divided into the real and the imaginary. The cause of real is mostly wind, cold, phlegm and fire, the disease is located in the lung and stomach, and comes from external sensation. For those with sweating, scaphozel, almond, orange peel, mother of pearl, scutellaria, forsythia, gypsum, etc.; for those without sweating, hemp, apricot, stone, mulberry leaf, mother of pearl, orris, etc. If the form is cold and the surface heat does not rise, the cough is not smooth and the pulse is floating and tight, the pathogenesis lies in wind-cold occlusion of the lung channels, and the lung qi is not able to be declared and lowered. Treatment should include ephedra, almonds, Su Ye, Radix Eucommiae, or Feng Feng Tong Sheng San to develop the coup de grace. The deficiency is due to internal deficiency of the lungs and kidneys, lack of power to subdue and take in, and deficiency of the spleen and stomach qi, which can not transform the essence of food and drink, resulting in the internal production of phlegm and drinks, which are stagnant in the lungs and stomach, and once the cold and external evil, the lungs and stomach lose their subdue, inducing the kidney qi to override. In addition, the classification of asthma in Chinese medicine also includes the asthma of blood stasis, the asthma of fire, the asthma of salt and sugar, etc. No matter what kind of asthma, it is the result of injury to lung qi. In short, real asthma is treated for the lung, taking into account the treatment of the stomach; deficiency asthma is treated for the kidney, taking into account the treatment of the lung. In general, if there is a lot of phlegm and the pulse is empty and stringy, the kidney should be treated; if there is little phlegm and the pulse is deficient and not large, the lung should be treated; if the phlegm is thin and frothy, it is appropriate to warm it; if the phlegm is little and yellow, it is appropriate to calm it down.
