Lung abscess (Fei Yong) is a condition formed by the accumulation of Qi in the lung due to injury by cold pathogens. The Lung governs Qi, and its manifestation is observed in the skin and hair. If labor and fatigue damage the Blood and Qi, the Cou Li (pores and interstices) become open, allowing wind pathogens to invade. If dry mouth occurs, and the pulse is slightly tight and rapid, it indicates that pus has not yet formed. If the pulse is very tight but only rapid, it indicates that pus has already formed. Furthermore, lung disease should present with coughing, shortness of breath, and expectoration of pus and blood; the pulse should be short and choppy. If the pulse is instead floating and large, it is a death sign. If the complexion should be white but appears red instead, this represents Fire overcoming Metal, which is a counterproductive pattern and is difficult to treat.
