夫肺痈者，乃肺经感受风邪热毒所致也。此病多因久嗜炙爆肥腻，或劳伤气血，以致心
火炎炽，熏克肺金，致令咳嗽。咳而不已，遂成肺痿。若寸口脉数，其人咳中反有浊唾涎沫
者，亦为肺痿之疾。若口中辟辟燥，咳又胸中隐隐而痛，脉反滑数，此为肺痈，咳唾脓血。
脉数而虚者，为肺痿；脉数而实者，为肺痈。夫肺者五脏之华盖也，处于胸中，主于气，候
于皮毛。劳伤血气，腠理虚而风邪乘之，内感于肺也，则汗出恶风，咳嗽短气，鼻塞项强，
胸胁胀满，久久不瘥遂成前证，轻则为痿，甚则成痈。其候应乳上下隐隐而痛者肺痈也，若
肉微起者肺痈也。初起皆可救，若日久唾脓臭败者，不可治也。但诊其脉，微紧而数者，未
有脓也；若紧甚而数者，已有脓也。若脓如粳米粥及呕脓不止，其脉浮大而面色赤者，皆难
治；若脓自止，其脉短而涩，面色黄白者，皆可治。何以言之。盖脉浮大面赤，此心火克肺
金也，故难治。若脉短涩及面白者，此肺气未损也，故可治。治当补肺泻火，止嗽定喘为佳
。若不得卧者，可用葶苈大枣泻肺汤及桔梗薏苡黄 汤之类调之。全在保肺，活法施治，庶
可全生也。

肺痈，是由于肺经感受风邪与热毒所导致的疾病。此病多因长期嗜好煎炸、爆炒及肥腻食物，或劳力过度损伤气血，致使心火亢盛炎上，熏灼克制肺金，从而引起咳嗽。若咳嗽不止，最终会演变为肺痿（肺部组织萎弱不用的病证）。如果寸口脉象数急，且患者在咳嗽时反而吐出浑浊的唾液和涎沫，这也属于肺痿的病证。如果口中感觉干燥不适，咳嗽时胸中隐隐作痛，脉象反而滑数，这是肺痈，表现为咳吐脓血。脉象数而虚弱的，属于肺痿；脉象数而有力的，属于肺痈。
肺是五脏中的华盖（覆盖于其他脏腑之上的器官），位于胸中，主管气机，其状态反映在皮毛。若劳力过度损伤气血，导致腠理（皮肤纹理及汗孔）空虚，风邪便乘虚而入，内侵于肺，就会出现出汗、怕风、咳嗽、气短、鼻塞、项背强直、胸胁胀满等症状。若久治不愈，就会形成前述病症，轻者发展为肺痿，重者则形成肺痈。其症状表现为乳房上下区域隐隐作痛的，是肺痈；若肌肉微微隆起的，也是肺痈。初期皆可救治，若日久咳吐脓液且气味腥臭败坏，则难以治愈。
仅通过诊察脉象，若脉微紧而数，说明尚未成脓；若脉紧甚且数，说明已有脓液形成。若脓液如米粥状，且呕吐脓液不止，脉象浮大且面色赤红，都属难治之症；若脓液自然停止排出，脉象短涩，面色黄白，则皆可治愈。为何这样说？因为脉浮大且面赤，这是心火克制肺金的表现，所以难治。若脉短涩且面白，说明肺气未受严重损伤，所以可治。治疗应当以补肺泻火、止咳定喘为佳。若患者无法平卧，可使用葶苈大枣泻肺汤（Tingli Dazao Xiefei Decoction）及桔梗薏苡黄耆汤（Jiegeng Yiyi Huangqi Decoction）等方剂进行调理。关键在于保护肺气，灵活运用方法施治，才可能保全生命。

治肺痈方
上述方法：将薏苡米研为细末，用糯米饮调服，或者加入粥中煮熟食用亦可。另一法用水煎服，当下脓血后即可痊愈。
Pulmonary abscess (Fei Yong) is a disease caused by the lung meridian contracting wind pathogenic factors and heat toxins. This illness often arises from long-term indulgence in fried, roasted, and fatty foods, or from labor-induced damage to Qi and Blood, leading to hyperactive heart fire that scorches and overacts on Lung Metal, resulting in cough. If the cough persists, it may eventually evolve into pulmonary consumptive disease (Fei Fei). If the Cun position of the pulse is rapid, and the patient produces turbid saliva and frothy sputum during coughing, this also belongs to pulmonary consumptive disease. If the mouth feels dry, coughing is accompanied by dull pain in the chest, and the pulse is slippery and rapid, this indicates pulmonary abscess, characterized by coughing up pus and blood. A rapid but deficient pulse indicates pulmonary consumptive disease; a rapid and excess pulse indicates pulmonary abscess.
The lung is the canopy of the five zang organs, located in the chest, governing Qi, and its condition is reflected in the skin and hair. If labor damages Qi and Blood, causing the interstices (Cou Li) to become deficient, wind pathogens can invade internally affecting the lungs, leading to sweating, aversion to wind, cough, shortness of breath, nasal congestion, stiffness of the neck and back, and distension and fullness in the chest and hypochondrium. If these symptoms persist without resolution, they develop into the aforementioned conditions: mild cases become pulmonary consumptive disease, while severe cases become pulmonary abscess. Symptoms manifesting as dull pain above and below the breasts indicate pulmonary abscess; slight swelling of the flesh also indicates pulmonary abscess. Early stages are treatable; however, if pus is coughed up after a long duration with a foul, rancid odor, it becomes difficult to treat.
Regarding pulse diagnosis: a slightly tight and rapid pulse indicates that pus has not yet formed; a very tight and rapid pulse indicates that pus has already formed. If the pus resembles rice gruel, vomiting of pus continues incessantly, the pulse is floating and large, and the complexion is red, all these are difficult to treat. If the pus stops spontaneously, the pulse is short and choppy, and the complexion is yellowish-white, these are treatable. Why? Because a floating, large pulse with a red complexion indicates heart fire overacting on Lung Metal, hence difficult to treat. A short, choppy pulse with a pale complexion indicates that Lung Qi is not severely damaged, hence treatable. Treatment should focus on tonifying the lung, draining fire, stopping cough, and calming asthma. If the patient cannot lie flat, Tingli Dazao Xiefei Decoction (Tingli Dazao Xiefei Tang) or Jiegeng Yiyi Huangqi Decoction (Jiegeng Yiyi Huangqi Tang) may be used for regulation. The key lies in protecting Lung Qi and applying flexible treatment methods to preserve life.
