Discussion: Lung abscess (Fei Yong) is characterized by a rapid and full pulse. This occurs because wind pathogen invades the Wei level (Defensive Level), preventing Qi from entering during exhalation; heat pathogen penetrates the Ying level (Nutritive Level), preventing Qi from exiting during inhalation. Wind-heat stagnates, accumulates, and consolidates to form an abscess. The symptoms include aversion to cold, dry mouth, dull pain in the chest, cough with chest fullness, and expectoration of foul-smelling saliva. It should be treated promptly; if delayed, pus resembling congee will be coughed up. Early intervention can save the patient, but once pus has formed, it is difficult to treat.
