Lung Obstructed by Damp-Phlegm
Diagnoses

definition and etiology

» conventional diagnoses: chronic bronchitis; bronchial asthma; bronchiectasis; pleurisy

» etiology: predisposed by Xu (Deficiency) of Spleen Qi and/or Spleen Yang; recurrent attacks of exogenous pathogenic factors weaken Lung and Spleen and lead to formation of Phlegm which subsequently settles in the Lung, e.g., sequelae to pertussis in children; excess dietary consumption of greasy foods and/or Cold and raw foods leads to formation of Phlegm and may thus contribute to this pattern.
