There is no easiest way to recognize Lung Qi deficiency and Lung Yin deficiency. Lung qi deficiency and lung yin deficiency can be recognized by their symptoms. Lung qi deficiency can be characterized by coughing, thin sputum, weak breath, and a low cough; lung yin deficiency can be characterized by a dry cough with no sputum or blood in the sputum, hot flushes (bursts of heat), and a dry mouth and throat. Lung qi deficiency may be manifested as cough and wheezing, sputum is clear and thin, asthma is weak, cough is low, breathlessness and laziness (lack of strength, don’t want to talk), fear of cold and spontaneous sweating (involuntary sweating during the daytime, sweating is aggravated with a little movement), etc. The tongue coating is pale white and the pulse is weak. Lung Yin deficiency can be manifested as dry cough without sputum or blood in sputum, hot flashes (a burst of fever), dry mouth and throat, night sweating (abnormal sweating after going to sleep, and sweating stops after waking up), five heart-heat (heat in the heart of the two hands and two feet, and self-consciousness of the heart and chest) and other symptoms, the tongue texture is reddish, the tongue is less fluid, and the pulse is fine (the pulse is becoming narrower and finer and the rate is accelerated). Clinically, for the treatment of lung qi deficiency, through diagnosis and analysis, the addition of tonic lung soup can be used, which can have the effect of tonifying the lung and benefiting the qi. For the treatment of lung yin deficiency, after diagnosis, Sha Shen Maidong Tang can be added and reduced to resolve phlegm and stop cough, nourish yin and moisten the lungs (replenish the yin fluid in the body to nourish the lungs). To differentiate between lung yin deficiency and lung qi deficiency, professional Chinese medicine practitioners should analyze the evidence, and patients should consult a doctor promptly if they suspect that they have lung deficiency.
