【胃痈】
病症由寒气阻隔阳气，导致热邪聚集在胃部，寒热失调，致使血肉腐败坏死。气机上逆于胃，使人出现像疟疾一样的寒热交替症状，伴有咳嗽、呕吐脓液、吐血。如果脉象洪大而数，说明脓液已经形成，应立即使用排脓的方剂；如果脉象迟而紧，属于瘀血阻滞，可以使用泻下法治疗。如果不及时治疗，毒邪内攻，危害极大。
主方：射干、山栀、赤茯苓、升麻（各一钱），赤芍（一钱五分），白术、连翘（各五分）。以上药材用水煎煮后服用。
薏苡仁汤：治疗风热引起的嘴唇口角颤动，或出现结节肿块，或浮肿。
配方：防风、薏苡仁、赤小豆、甘草（炙过，各等分）。以上药材用水煎煮后服用。
【肺痈】
肺痈，是由于风寒侵袭肺经，导致肺气结聚而形成的。肺主管气，外合皮毛。如果劳倦损伤气血，腠理（皮肤纹理及汗孔）就会疏松敞开，寒邪便乘虚侵入。寒邪与血液搏结，蕴积而成痈肿。积热不散，败坏的血液化为脓液。患者会出现气喘咳嗽，胸部内部胀满，隐隐作痛，兼有右侧胁肋疼痛且身体战栗动摇，咽喉干燥，口中感觉燥热但不想喝水，时常吐出浑浊带有腥臭味的痰液，时间久了吐出像米粥一样的脓液，这种情况难以治愈。如果寸口脉象紧、数且实，就是肺痈的征象。治疗方法：
初起时宜先服用小青龙汤（方剂见寒门章节），只需一剂，以疏散风邪；接着服用主方：黄耆、桔梗、贝母、薏苡仁、百合（各一钱），当归、枳壳、栝蒌、桑白皮、防己、杏仁（去皮尖）、甘草节（各七分）。加入生姜五片，水两碗，煎煮后服用。如果大便秘结，加大黄（五分）。
又一方：知母、贝母、生地、阿胶、桑白皮、射干、桔梗、天门冬、杏仁、薄荷、白芨（各七分），甘草（五分），乌梅（一个）。加生姜三片，大枣二枚，用水煎煮，饭后服用。如果痰多，加天南星、半夏。如果是风寒引起，加防风、白芷、紫苏。
排脓补肺：用黄耆（一两）水煎服用。或者多用甘草、桔梗煎煮服用。
又方：葶苈大枣泻肺汤适宜服用（方剂见喘门章节）。
简便方：槿树皮水煎服用。或者乌农树皮煎服。或者用薏苡仁煮粥食用。
又方：将白芨研成粉末，每次用两钱，用温水送服。或者用槿皮、白蔹煎服。或者用苇叶煎汤作为饮料饮用。
[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:
