[Stomach Abscess]
The pathology arises from cold qi obstructing yang, causing heat to accumulate in the stomach region. The disharmony of cold and heat leads to the corruption and necrosis of flesh and blood. Qi rebels upward in the stomach, causing chills and fever resembling malaria, accompanied by cough, vomiting of pus, and hemoptysis. If the pulse is surging and rapid, it indicates that pus has formed; an agent for discharging pus should be urgently administered. If the pulse is slow and tight, it belongs to blood stasis, and purgation may be used. Otherwise, toxic factors will attack internally, causing significant harm.
Main Formula: Belamcandae Rhizoma (Shéyān), Gardeniae Fructus (Shānzhī), Poria (Chì Fúlíng), Cimicifugae Rhizoma (Shēngmá) (each 1 qian), Paeoniae Radix Rubra (Chìsháo) (1.5 qian), Atractylodis Macrocephalae Rhizoma (Baízhú), Forsythiae Fructus (Liánqiào) (each 0.5 qian).

[Lung Abscess]
Lung abscess is caused by wind-cold injuring the Lung meridian, leading to the aggregation of Qi. The Lung governs Qi and corresponds to the skin and hair. Fatigue and injury to Qi and blood cause the couli (pores) to open loosely, allowing cold pathogens to enter through the deficiency. Cold contending with blood accumulates and forms an abscess. Accumulated heat fails to dissipate, turning corrupted blood into pus. The patient experiences wheezing and coughing, fullness in the chest, dull pain, accompanied by pain in the right hypochondrium with tremors, dry throat, a sensation of dryness in the mouth without thirst, frequent expectoration of turbid sputum with a foul odor, and eventually expectoration of pus resembling congee, which is difficult to treat. If the cun position of the pulse is tight, rapid, and excess, it indicates Lung abscess. Treatment method:
