一义官仲冬时督工河道，不常迎风呼唤，致肺受伤，后发此症。初起寒热交作，咳嗽声重，气急生痰，请
内医治之，越治越重。后予视，诊其脉浮而数，面光而泽，此肺痈也。视其痰果有脓意相粘，以桔梗汤二服，
咳嗽稍止；以排脓散四服，其脓渐多，惟胸膈疼痛不减，脉亦带芤，此胸中有瘀血也。以四顺散加红花、牡丹
皮二服，吐出紫血碗许，随后膈痛渐止；又以金鲤汤兼人参五味子汤间服，月余而愈。
一男子久嗽不已，咳吐脓痰，面白神劳，胸中隐痛，诊之脉浮微数，此属肺气不足，火尚有余。以知母茯
苓汤数服，其脓渐少，又以清金宁肺丸服之而愈。
一男子因劳伤咳嗽不止，至夜身热尤甚，日久咯吐脓血，
诊之脉弦而数，此虚火假症也。先以童子小便日饮三、四次，又服紫菀茸汤数剂，至夜身热不发，又间服金鲤
汤月余而渐瘳，此非童便之功而阴火岂能得退，尝治疮疡虚热不退者，用此极效。
一男子郁郁不遂意，患嗽半年，时或咳吐脓血，且形体衰弱，饮食减少，脉亦微数，声渐将雌；惟面不红，
其病将成肺痿，而尚可治。以清金二母汤十余服，咳吐减半，又以金鲤汤与人参五味子汤间服之，又早饮人乳、
晚饮童便各一钟，调理百日外而安。
一男子生平好饮，口干作渴，致肺壅热成痈，咳吐脓痰，喘满难卧。以葶苈散二服，而喘定易睡；又以紫
菀茸汤加干葛、天花粉十余服而脓痰渐少；早以加减八味丸，午用清金宁肺丸间服之，两月而愈。
一男子五十余岁，平素宠外家、膏粱，复生咳嗽发热，吐痰腥臭，视之手掌枯涩，面隐微红，痰中白血，脉
亦细微而数，此肺痈所忌症也。辞不治。后医强许其生，而用药终至不应乃死。人问曰∶何以致之？予曰∶手
掌干涩，血枯土伤，不能生其金也；面色微红，相火已动；痰中白血，正肺受伤；脉细而数，真气虚败。凡肺
痈犯此，岂有不死者乎！以此言之后，人乃服。
初起时脉象浮虚细，身体不发热，咳嗽有痰，呼吸均匀顺畅的，为顺证。脓疡已成时脉象浮而微数，咳吐脓痰，色泽鲜明，声音清朗的，为吉兆。溃破后咯吐脓痰，偶尔吐出鲜血，症状时发时止，饮食有味道的，为顺证。
若吐出的脓液逐渐减少，胸胁部不疼痛，面色微微发黄，大便通畅但秽浊；或者初起时脉象洪大弦数，身体发热且恶寒明显，胸痛气喘，面红多汗的，为损寿之逆证。脓疡已成时咯吐脓痰，气味腥臭，黄痰如胶粘固着，唇口内翻的，最终会导致死亡。若咯吐时兼有白血，气急烦躁，指甲紫暗且弯曲，最终归于死亡。手掌干枯如枯树，面部颧骨处艳红，咽喉疼痛声音嘶哑如鸭叫，鼻翼扇动的，最终死亡。
初起时风寒邪气侵入，头晕恶寒，咳嗽声音沉重的，宜用发散风邪的方法治疗。若汗出恶风，咳嗽气急，鼻塞项强，胸膈隐痛，宜用实表清肺的方法治疗。白天怕冷，喜欢多穿衣被，夜间发热，烦躁去掉衣被，宜用滋阴养肺的方法治疗。口干喘满，咽痛咳嗽且口渴，咳嗽身热、脉弦数的，宜用降火抑阴的方法治疗。胸满喘急，咳吐脓痰，身热气粗，不能安卧，宜用平肺排脓的方法治疗。热退身凉，脉来短涩，精神减少，自汗盗汗，宜用补肺健脾的方法治疗。
有一位义官在仲冬时节督工河道工程，经常迎风呼唤，导致肺部受伤，后来发生此症。初起时寒热交替发作，咳嗽声音沉重，气急生痰，请内科医生医治，病情反而加重。后来我诊治，诊得脉象浮而数，面色光亮润泽，这是肺痈。观察其痰液果然有脓意且粘稠，服用两剂桔梗汤后，咳嗽稍止；服用四剂排脓散后，脓液逐渐增多，只有胸膈疼痛不减，脉象也带芤象，这是胸中有瘀血。于是用四顺散加红花、牡丹皮，服用两剂后，吐出约一碗紫血，随后膈痛逐渐停止；接着又让患者间服金鲤汤和人参五味子汤，月余后痊愈。
有一位男子久咳不止，咳吐脓痰，面色苍白神疲乏力，胸中隐痛，诊得脉象浮微数，这属于肺气不足，火邪尚有余。服用数剂知母茯苓汤后，脓液逐渐减少，又服用清金宁肺丸而痊愈。
有一位男子因劳伤导致咳嗽不止，到了夜间身体发热尤其严重，日久咯吐脓血，诊得脉象弦而数，这是虚火假症。先让他每日饮用童子小便三到四次，又服用数剂紫菀茸汤，夜间身体发热不再发作，又间服金鲤汤，月余后逐渐好转。这不是童子小便的功效，而是阴火得以消退。我曾治疗疮疡虚热不退的患者，用此法极有效。
有一位男子郁郁不得志，患咳嗽半年，有时咳吐脓血，且形体衰弱，饮食减少，脉象微数，声音逐渐变得雌柔（嘶哑）；只有面色不红，病将发展为肺痿，但尚可治疗。服用十余剂清金二母汤后，咳吐减半，又间服金鲤汤和人参五味子汤，并且早上饮用人乳、晚上饮用童子小便各一杯，调理百日以上而安宁。
有一位男子生平喜好饮酒，口干作渴，导致肺壅热成痈，咳吐脓痰，喘满难以卧床。服用两剂葶苈散后，喘息定止容易入睡；又服用十余剂紫菀茸汤加干葛、天花粉，脓痰逐渐减少；早上服用加减八味丸，中午服用清金宁肺丸，间服之，两月后痊愈。
有一位五十多岁的男子，平素宠爱妻室、食用肥甘厚味，又生咳嗽发热，吐痰腥臭，观察其手掌枯涩，面色隐隐微红，痰中带白血，脉象细微而数，这是肺痈所忌讳的症状。我推辞不予治疗。后来的医生强行承诺能治好，但用药始终无效最终死亡。有人问我说：“为什么会这样？”我说：“手掌干涩，是血枯土伤，不能生金（肺）；面色微红，是相火已动；痰中白血，是正气肺脏受伤；脉细而数，是真气虚败。凡是肺痈出现这些症状，哪有不死人的呢！”说完这番话后，人们才信服。
In the initial stage, if the pulse is floating, deficient, and fine, the body is not hot, there is cough with sputum, and breathing is regular and smooth, it is a favorable condition (Shun). When the abscess has formed, if the pulse is floating and slightly rapid, pus-like sputum is expectorated, the color and shape are bright and distinct, and the voice is clear, it is an auspicious sign. After ulceration, if pus-like sputum is spat out, occasional fresh blood is expelled, symptoms come and go, and the sense of taste in food remains, it is a favorable condition.
If the discharged pus gradually decreases, the chest and hypochondrium are not painful, the complexion is slightly yellowish, and stool is regular but foul; or if in the initial stage the pulse is surging, wiry, and rapid, the body is hot with significant aversion to cold, chest pain and panting occur, the face is red with profuse sweating, this indicates damage to longevity. When the abscess has formed, if pus-like sputum is expectorated with a foul odor, yellow sputum is sticky and fixed, and the lips invert, death will eventually ensue. If white blood/pus is also expectorated along with rapid breathing and irritability, and the fingernails are purple and curved, death is inevitable. If the palms are dry like dead wood, the malar region is brightly red, there is sore throat with hoarseness resembling a duck's quack, and nasal flaring occurs, death is final.
In the initial stage, when wind-cold pathogens invade, causing dizziness and aversion to cold, and cough with a heavy voice, methods for dispersing wind pathogens should be used. If there is sweating with aversion to wind, cough with rapid breathing, nasal congestion, neck stiffness, and hidden pain in the chest and diaphragm, methods for consolidating the exterior and clearing the lungs should be used. If there is aversion to cold during the day, preferring to wrap in clothes and blankets, fever at night, irritability leading to removing covers, methods for nourishing yin and tonifying the lungs should be used. If there is dry mouth, panting and fullness, sore throat with cough and thirst, cough with body heat, and a wiry-rapid pulse, methods for descending fire and suppressing yin should be used. If there is chest fullness, rapid panting, expectoration of pus-like sputum, body heat with coarse breathing, and inability to lie down comfortably, methods for calming the lungs and draining pus should be used. If heat recedes and the body cools, the pulse becomes short and choppy, spirit diminishes, spontaneous sweating and night sweats occur, methods for tonifying the lungs and strengthening the spleen should be used.
A righteous official, while supervising river works in mid-winter, frequently called out facing the wind, injuring his lungs, which later led to this disease. Initially, alternating chills and fever occurred, with heavy coughing, rapid breathing, and phlegm production. He consulted internal medicine physicians, but the condition worsened. I then examined him, finding a floating and rapid pulse, and a shiny, lustrous complexion, diagnosing Lung Abscess (Fei Yong). Observing that his sputum indeed had the nature of pus and was sticky, he took two doses of Jiegeng Tang (Platycodon Decoction), after which the cough subsided slightly; he took four doses of Painong San (Pus-Draining Powder), after which the pus increased gradually. However, chest and diaphragmatic pain persisted, and the pulse showed a Kou (hollow) quality, indicating blood stasis in the chest. Therefore, Sishun San (Four-Compliant Powder) was administered with Honghua (Carthamus Flower) and Mudanpi (Moutan Cortex) for two doses, resulting in the expectoration of about one bowl of purple blood, after which the diaphragmatic pain gradually ceased. Subsequently, Jinli Tang (Golden Carp Decoction) and Renshen Wuweizi Tang (Ginseng and Schisandra Decoction) were taken alternately, and he recovered after more than a month.
A man suffered from persistent chronic cough, expectorating pus-like sputum, with a pale complexion and mental fatigue, and hidden pain in the chest. His pulse was floating, slight, and rapid, indicating insufficient Lung Qi with residual fire. After several doses of Zhimu Fuling Tang (Anemarrhena and Poria Decoction), the pus decreased gradually, and he recovered after taking Qingjin Ningfei Wan (Clear Metal and Calm Lung Pill).
A man suffered from continuous cough due to labor injury, with severe body heat at night. Over time, he expectorated pus and blood. His pulse was wiry and rapid, indicating false symptoms of deficiency fire. First, he drank Boyzi Xiaoye (Child Urine) three to four times daily, and took several doses of Ziwan Rong Tang (Aster Root Decoction), after which night fever ceased. He then took Jinli Tang (Golden Carp Decoction) intermittently, recovering gradually over a month. This was not merely due to child urine, but because the deficient fire retreated. I have treated patients with non-resolving deficiency heat from sores using this method with great efficacy.
A man was depressed and dissatisfied, suffering from cough for half a year, occasionally expectorating pus and blood, with emaciation and reduced appetite. His pulse was slight and rapid, and his voice was becoming hoarse/feminine; only his face was not red. The disease was progressing toward Lung Flaccidity (Fei Fei), but was still treatable. After more than ten doses of Qingjin Ermu Tang (Clear Metal and Two Mothers Decoction), cough and expectoration halved. He then took Jinli Tang (Golden Carp Decoction) and Renshen Wuweizi Tang (Ginseng and Schisandra Decoction) alternately, drinking human milk in the morning and child urine in the evening, each one cup, and stabilized after more than a hundred days of regulation.
A man who enjoyed drinking developed dry mouth and thirst, leading to lung obstruction, heat accumulation, and abscess formation, with expectoration of pus-like sputum, panting, fullness, and inability to lie down. After two doses of Tingli San (Descurainia Seed Powder), panting stopped and sleep improved. After more than ten doses of Ziwan Rong Tang (Aster Root Decoction) added with Gan Ge (Kudzu Root) and Tianhuafen (Trichosanthes Root), pus-like sputum decreased. He took Jiaban Bawei Wan (Modified Eight Flavor Pill) in the morning and Qingjin Ningfei Wan (Clear Metal and Calm Lung Pill) at noon, taken alternately, and recovered in two months.
A man over fifty years old, accustomed to indulging in sexual activity and rich/greasy foods, developed cough, fever, and expectoration of fishy-smelling sputum. His palms were dry and rough, his face was faintly red, sputum contained white blood, and his pulse was fine, slight, and rapid. These are contraindicated signs for Lung Abscess (Fei Yong). I declined to treat him. Later physicians insisted on treatment, but medication failed, and he died. Someone asked, "Why did this happen?" I said, "Dry palms indicate blood depletion and earth injury, failing to generate metal (lung); faint red face indicates ministerial fire activation; white blood in sputum indicates injury to healthy lung qi; fine and rapid pulse indicates exhaustion of true qi. Anyone with Lung Abscess presenting these signs cannot survive." After stating this, people accepted it.
