问曰：热在上焦者，因咳为肺痿，肺痿之病，从何得之？师曰：或从汗出，或从呕吐
，或从消渴，小便利数，或从便难，又被快药下利，重亡津液，故得之。曰：寸口脉
数，其人咳，口中反有浊唾涎沫者何？师曰：为肺痿之病。若口中辟辟燥，咳即胸中
隐隐痛，脉反滑数，此为肺痈，咳唾脓血。
【注】
热在上焦，不咳，不病肺痿也，因热病咳，则为肺痿。肺热致痿之由，非止一端，或
从汗出，或从呕吐，或从消渴，小便数利，或从便难，又被快药下之，重亡津液，故
令肺热干痿也。肺热干痿，则清肃之令不行，水精四布失度，脾气虽散，精液上归于
肺，而肺不但不能自滋其干，亦不能内洒陈于藏府，外输精于皮毛也。其精液留贮胸
中，得热煎熬，变为涎沫，侵肺作咳，唾之不已，故干者自干，唾者自唾，愈唾愈干
，痿病成矣。若口中辟辟干燥，不吐浊唾涎沫，每咳即胸中隐隐而痛，脉数而滑，不
数而虚，则非肺痿乃为肺痈，久则痈成脓溃，不唾涎沫，而必咳唾脓血矣。

此承上条，以明急治之义也。肺痈者，谓口中辟辟干燥，胸中隐隐作痛，脉数实也。

问：热邪位于上焦，因咳嗽而发展为肺痿（肺部组织枯萎萎缩的病证），肺痿病是如何产生的呢？老师说：有的因为发汗过多，有的因为频繁呕吐，有的因为消渴病导致小便频数，有的因为大便干结，又误用峻下药物导致腹泻，双重损耗津液，因此得此病。问：寸口脉象数（快），病人咳嗽，口中反而有浑浊的唾液和涎沫，这是什么原因？老师说：这是肺痿病。如果口中感觉干燥爆裂，一咳嗽就胸中隐隐作痛，脉象反而滑数，这是肺痈（肺部化脓性炎症），会咳吐脓血。
【注释】
热邪在上焦，如果不咳嗽，就不会患肺痿；因热病引发咳嗽，才会成为肺痿。导致肺热引起肺痿的原因不止一种，或是因为发汗过多，或是因为呕吐，或是因为消渴病小便频数，或是因为大便困难，又被峻下药攻下导致严重损伤津液，所以使肺热干枯萎缩。肺热干枯萎缩，那么肺的清肃功能就不能正常行使，水液精微布散失去节制，虽然脾气将精液上输于肺，但肺不但不能滋润自身的干枯，也不能向内灌溉五脏六腑，向外输送精微至皮毛。这些精液留存在胸中，受热煎熬，变成涎沫，侵犯肺部引起咳嗽，不停地咳吐，所以干的依然干，吐的依然吐，越吐越干，肺痿病就形成了。如果口中感觉干燥爆裂，不吐出浑浊的唾液涎沫，每次咳嗽就胸中隐隐作痛，脉象数而滑，或者数而虚，这就不是肺痿而是肺痈，时间久了就会形成痈脓溃烂，不吐涎沫，而是咳吐脓血。
【集注】
周扬俊说：喻昌说：走几步路，气息就喘息鸣响，冲击发出连续声音，痰声才应和。《金匮要略》的治疗法则，贵在领会其精意，大抵要缓慢图谋，滋生胃中津液，润泽肺部燥热，降逆气，开积痰，止浊唾，补真气，以通畅肺的小管，疏散火热，恢复肺的清肃功能，就像半身痿废及手足痿软一样，治疗得当，也能康复。肺就在胸中，关乎呼吸，怎能不致力治疗呢？肺痈属于有形的血液病变，血结应当迅速攻逐；肺痿属于无形的气分病变，气伤应当慢慢调理。所以痈是实证，误用治肺痿的方法治疗，就是实实之误（使实证更实）；痿是虚证，误用治肺痈的方法治疗，就是虚虚之误（使虚证更虚）。这是辨证用药的大致原则。然而两手寸口脉，原本都是手太阴肺经的脉象，这里说寸口脉数、滑数、数实、数虚，都是指左右三部脉统而言之，不像气口独主右关脉那样。病人咳嗽，口中反而有浑浊的唾液涎沫，一会儿遍地都是的是肺痿，意思是咳嗽而口中不干燥。如果咳嗽而口中感觉干燥爆裂，那就是肺已经结成痈，火热毒气表现在口部，咳嗽声上下震动，触动痈肿，胸中立即隐隐作痛，脉象必然见滑数有力，这是正邪气正盛的征象。用数虚或数实的脉象来区分肺痿和肺痈，那么肺痿应当补益，肺痈应当泻实，就可以知道了。又说：刚见到久咳，先须防备这两种证候，肺痈是由五脏蕴积之火，与胃中停蓄之热，上乘于肺，肺受火热熏灼，血液为之凝结，痰浊为之包裹，遂成小痈。所结成的形状逐渐长大，则肺日益胀大，肋骨日益外昂，以至于咳嗽声频繁，痰浊如胶，发热畏寒，下午尤其严重，面色红，鼻燥，胸生肌肤甲错。起初如果能辨别其脉证，属表属里，极力采用开提或攻下的方法，没有不愈的。等到血液化为脓，肺叶朽坏，像倾倒口袋一样吐出，这时才认识其证候，十死无救，叹息也来不及了。
沈明宗说：这是肺痿和肺痈的鉴别。心居上位，肾水不足，心火克制肺金，造成热在上焦，肺阴日渐消耗，气逆则咳嗽，所以导致肺痿。然而本经明确说明初病的病因，有的是病后阴虚，过汗伤液，呕吐伤津，消渴，血虚津竭；或者是利小便，次数多而伤阴；或者是大便难，反被峻下药攻下而再次亡失津液，以致肺金枯燥，虚热熏蒸，所以寸口脉数，病人咳嗽，气弱不振，津液不布散，化为浊唾涎沫而成肺痿。如果口中感觉干燥爆裂，咳嗽即胸中隐隐作痛，那是风寒侵入肺中，凝滞营血形成痈，所以脉滑数而咳吐脓血。因为无形虚热导致痿，所以脉数而虚；因为有形气血凝滞形成痈，所以脉数而实。这明确了肺痈属实、肺痿属虚。
【注释】
这是详细阐述上一条关于肺痿、肺痈的脉象。肺痿是由于热邪亡失津液所致，属于虚邪，所以脉数而虚；肺痈是由于热毒蓄积结聚所致，属于实邪，所以脉数而实。
【集注】
李□说：潘硕甫说：痿和痈，都是热在上焦，其脉象都数，都咳嗽，都亡失津液，没有不同之处。但痿属于肺气虚而亡津，虽然有热也不猛烈，所以不至于燥涸，虽然咳嗽但口中有浊唾涎沫，所以脉虽数而虚。痈则是气壅血凝，邪气实而热势烈，所以津液亡失而更觉得干涸，口中感觉干燥爆裂，咳嗽即胸中隐痛，津液既已枯竭，脉象理应涩滞反而滑数的，是因为蓄热腐肉成脓，所以脉数而实。
尤怡说：痿就是萎，像草木枯萎而不繁荣，是因为津液亡失而肺焦枯；痈就是壅，像泥土壅塞而不通，是因为热邪聚集而肺阻塞。所以它们的脉象有虚实不同，但其数脉是一样的。
问：患咳嗽气逆病，诊脉怎么知道这是肺痈？应当有脓血，吐出来就会死，它的脉象是什么样的？老师说：寸口脉微而数，微表示风邪，数表示热邪；微则汗出，数则恶寒，风邪伤及卫分，呼气不能深入；热邪过于营分，吸气不能外出。风邪伤害皮毛，热邪伤害血脉。风邪舍居于肺，病人就会咳嗽，口干，气喘胸闷；咽喉干燥但不口渴，时常吐浊沫，时时发冷战栗。热邪经过的地方，血液为之凝滞，蓄积结聚成痈脓，吐出物像米粥一样。初期尚可救治，脓已成则死。
【按语】
在“肺痈”之上，应当有“肺痿”二字，否则本文论述肺痿的意义就没有着落，必定是脱简。脉微中的三个“微”字，应当是三个“浮”字，“微”字文气不通顺，必定是传写之误。
【注释】
患咳嗽气逆病，怎么知道是肺痿还是肺痈呢？咳嗽而不渴，吐浊唾涎沫，脉数而虚，是根据脉证判断为肺痿。口中干燥，胸中隐痛，脉数而实，是根据脉证判断为肺痈。至于致病的原因，肺痿前面已经讲过，而肺痈却没有讲过，所以又取导致热邪而患肺痿肺痈的原因，互相详细阐明。寸口是肺脉，肺脉应当浮涩而短；现在浮而数，所以知道浮则为风，数则为热，初病风热，外搏皮毛，则营卫受邪，所以汗出而恶寒。未传入的风热，内舍于肺，则营卫分病。患肺痿的，属于风热伤于卫气，气分有津液而无血，津液变得浑浊，所以其症状是，咳嗽而不吐脓血，吐浊涎沫。患肺痈的，属于风热伤于营血，血分有血而无津液，血液凝滞蓄积，所以其症状是，咳嗽而不吐涎沫，吐脓血像米粥一样。其发热汗出，恶寒恶风，咳嗽而喘满，咽燥不渴，呼气不入，吸气不出，则是痿、痈互相兼有的必然证候。呼气不入，吸气不出，是说呼吸气促，难出难入，并不是完全不出入。初期可救，是说肺伤尚浅，脓已成则死，是说肺已败坏。这是告诉人们及早治疗，又特别针对肺痈谆谆告诫。
【注释】
这是承接上一条，以说明急治的意义。肺痈，是指口中感觉干燥爆裂，胸中隐隐作痛，脉数实。如果再出现气喘不能平卧，是邪气壅肺非常急迫，所以用葶苈大枣泻肺汤，药性大苦大寒，峻泻肺中邪气，恐怕稍加拖延，脓成就会死亡。
Question: When heat is located in the upper jiao (upper burner), it leads to Fei Wei (Lung Withering, a disease characterized withering and atrophy of lung tissue) due to coughing. How is the disease of Fei Wei acquired? The Master said: It may result from excessive sweating, or from frequent vomiting, or from Xiao Ke (Wasting-Thirst syndrome) causing frequent urination, or from constipation treated with harsh purgatives leading to diarrhea, resulting in a double loss of body fluids. Thus, this disease arises. Question: If the pulse at the cunkou (radial artery at the wrist) is rapid (shu), the person coughs, and there is instead turbid saliva and froth in the mouth, what is the cause? The Master said: This is the disease of Fei Wei. If the mouth feels parched and dry, and coughing causes a dull pain in the chest, and the pulse is slippery and rapid, this is Fei Yong (Lung Abscess, a suppurative inflammation of the lung), accompanied by coughing up pus and blood.
[Annotation]
Heat in the upper jiao does not cause Fei Wei unless it induces coughing; only when heat illness triggers coughing does it become Fei Wei. The causes of lung heat leading to withering are manifold: excessive sweating, vomiting, Xiao Ke with frequent urination, or constipation treated with harsh purgatives causing severe fluid depletion, all leading to lung heat drying and withering. When lung heat dries and withers, the lung's clear descending function fails, and the distribution of fluids and essences becomes disordered. Although the spleen transports essences upward to the lung, the lung cannot moisten its own dryness, nor can it irrigate the internal zang-fu organs or transport essences outward to the skin and hair. These essences accumulate in the chest, are boiled by heat, transform into froth, invade the lung causing cough, and are continuously expectorated. Thus, the dry remains dry, the expectoration continues, the more one expects, the drier it gets, and the Fei Wei disease is formed. If the mouth feels parched and dry, without expectorating turbid saliva or froth, and each cough causes dull chest pain, with a pulse that is either slippery-rapid or weak-rapid, this is not Fei Wei but Fei Yong. Over time, an abscess forms and ruptures with pus; instead of froth, pus and blood are coughed up.
[Collected Notes]
Zhou Yangjun stated: Yu Chang said: Walking just a few steps causes panting and wheezing, with continuous impact sounds and phlegm resonance. The treatment principles in *Jin Gui Yao Lue* emphasize grasping the essence: generally, proceed slowly. Generate stomach fluids, moisten lung dryness, descend rebellious qi, resolve accumulated phlegm, stop turbid expectoration, tonify true qi, unblock the small passages of the lung, dissipate fire-heat, and restore the lung's clear descending function. Just as hemiplegic withering or flaccidity of limbs can recover with proper treatment, so too can lung diseases. The lung is close to the chest and vital for respiration; how can we neglect it? Fei Yong belongs to tangible blood pathology; blood stasis should be attacked swiftly. Fei Wei belongs to intangible qi pathology; qi injury should be managed gradually. Therefore, Yong is excess; treating it like Wei constitutes "excess reinforcing excess." Wei is deficiency; treating it like Yong constitutes "deficiency weakening deficiency." This is the general principle of syndrome differentiation and medication. However, the cunkou pulse on both hands refers to the Lung Meridian of Hand-Taiyin. Statements regarding rapid, slippery-rapid, excess-rapid, or deficient-rapid pulses refer collectively to the three positions on both sides, not exclusively to the right guan position as in some contexts. Coughing with turbid saliva and froth filling the ground indicates Fei Wei, meaning the mouth is not dry. If coughing accompanies a parched mouth, it indicates lung abscess formation; fire-toxin manifests orally, and coughing vibrations irritate the abscess, causing dull chest pain. The pulse must be slippery-rapid and forceful, a sign of vigorous pathogenic qi. Using deficient-rapid or excess-rapid pulses to distinguish Fei Wei from Fei Yong reveals that Fei Wei requires tonification and Fei Yong requires purgation. Furthermore, upon observing chronic cough, one must guard against these two syndromes. Fei Yong arises from fire accumulating in the five zang organs and heat stagnating in the stomach, ascending to the lung. The lung is scorched by fire-heat, causing blood coagulation and phlegm wrapping, forming a small abscess. As the lesion grows, the lung swells and ribs flare. Symptoms include frequent coughing, thick phlegm like glue, fever, aversion to cold (worse in the afternoon), red face, dry nose, and skin resembling fish scales on the chest. If identified early, distinguishing exterior/interior patterns and using lifting or purging methods ensures recovery. Once blood turns to pus and lung tissue rots, expectorated like an overturned bag, recognition comes too late; ten cases die, and it is futile to sigh.
Shen Mingzong said: This distinguishes Fei Wei from Fei Yong. Heart resides superiorly; if kidney water is insufficient, heart fire insults metal (lung), creating heat in the upper jiao. Lung yin declines daily, qi rebels causing cough, leading to Fei Wei. The classic specifies initial causes: post-illness yin deficiency with excessive sweating injuring fluids, vomiting injuring fluids, Xiao Ke with blood deficiency and fluid exhaustion, or diuretics causing frequent urination injuring yin, or constipation treated with harsh purgatives causing double fluid loss. This leads to lung metal dryness, steaming by deficient heat, rapid cunkou pulse, coughing, weak qi, failure of fluid distribution, transforming into turbid saliva and froth, forming Fei Wei. If the mouth is parched and coughing causes dull chest pain, it is wind-cold invading the lung, stagnating nutritive blood to form an abscess, resulting in slippery-rapid pulse and expectoration of pus and blood. Because intangible deficient heat causes withering, the pulse is rapid-deficient. Because tangible qi-blood stagnation forms abscess, the pulse is rapid-excess. This clarifies Fei Yong as excess and Fei Wei as deficiency.
A rapid-deficient pulse indicates Fei Wei; a rapid-excess pulse indicates Fei Yong.
[Annotation]
This elaborates on the pulses for Fei Wei and Fei Yong mentioned previously. Fei Wei results from heat destroying fluids, constituting a deficient pathogen, hence the rapid-deficient pulse. Fei Yong results from heat-toxin accumulation and knotting, constituting an excess pathogen, hence the rapid-excess pulse.
[Collected Notes]
Li [Name obscured] stated: Pan Shuofu said: Both Wei and Yong involve heat in the upper jiao, rapid pulses, coughing, and fluid loss, appearing similar initially. However, Wei involves lung qi deficiency and fluid loss; although heat exists, it is not intense, so it does not reach extreme dryness. Coughing occurs with turbid saliva/froth, so the pulse is rapid-deficient. Yong involves qi stagnation and blood coagulation; pathogenic excess and intense heat cause greater fluid loss and dryness. The mouth feels parched, coughing causes dull chest pain. With fluids exhausted, the pulse should be choppy but is instead slippery-rapid because accumulated heat rots flesh into pus, making the pulse rapid-excess.
You Yi said: Wei means wither, like plants losing vigor due to fluid loss and lung scorching. Yong means blockage, like earth obstructed flow, due to heat aggregation and lung obstruction. Thus, their pulses differ in excess/deficiency, but both are rapid.
Question: In a patient with coughing and rebellious qi, how do we know this is Fei Yong? There should be pus and blood; if expectorated, death ensues. What does the pulse resemble? The Master said: The cunkou pulse is faint and rapid. Faint indicates wind; rapid indicates heat. Faint implies sweating; rapid implies aversion to cold. Wind injures the defensive layer, preventing deep inhalation; heat penetrates the nutritive layer, preventing exhalation. Wind damages the skin and hair; heat damages the vessels and blood. Wind lodging in the lung causes cough, dry mouth, panting and fullness; throat dryness without thirst, occasional expectoration of turbid froth, and intermittent chills. Where heat passes, blood coagulates and stagnates, accumulating into an abscess with pus expectorated like rice porridge. In the early stage, it is treatable; once pus forms, it is fatal.
[Commentary]
The phrase "Fei Wei" likely precedes "Fei Yong" in the original text; otherwise, the discussion of Fei Wei lacks context, suggesting a missing slip. The three instances of "faint" (wei) in the pulse description should likely be "floating" (fu); "faint" disrupts the textual logic, indicating a transcription error.
[Annotation]
How to distinguish Fei Wei from Fei Yong in coughing and rebellious qi? Cough without thirst, expectorating turbid saliva/froth, with a rapid-deficient pulse identifies Fei Wei. Dry mouth, dull chest pain, with a rapid-excess pulse identifies Fei Yong. The causes of Fei Wei were explained earlier; Fei Yong's causes were not. Thus, the mechanisms of heat causing these diseases are detailed. The cunkou is the lung pulse; normally floating-choppy-short. Now it is floating-rapid, indicating wind (floating) and heat (rapid). Initial wind-heat attacks the exterior, affecting Ying and Wei, causing sweating and aversion to cold. If wind-heat enters internally to lodge in the lung, Ying and Wei are affected differently. Fei Wei results from wind-heat injuring Wei Qi; the Qi level has fluids but no blood stasis; fluids become turbid. Symptoms: cough without pus/blood, expectorating turbid froth. Fei Yong results from wind-heat injuring Ying Blood; the Blood level has blood but no fluids; blood coagulates and stagnates. Symptoms: cough without froth, expectorating pus/blood like rice porridge. Fever, sweating, aversion to cold/wind, cough with panting/fullness, throat dryness without thirst, difficult breathing (inhaling/exhaling) are common to both. "Inhaling/exhaling difficulty" refers to shortness of breath, not total cessation. "Early stage treatable" means lung damage is superficial; "pus formed fatal" means lung tissue is destroyed. This warns for early treatment, specifically emphasizing Fei Yong.
In Fei Yong, with panting preventing lying down, Tingli Zaozao Xiefei Tang (Descurainia Seed and Jujube Decoction to Drain the Lung) is indicated.
[Annotation]
This follows the previous section to explain the necessity of urgent treatment. Fei Yong is characterized by a parched mouth, dull chest pain, and rapid-excess pulse. If accompanied by panting preventing recumbency, pathogenic stagnation in the lung is extremely urgent. Therefore, Tingli Zaozao Xiefei Tang, being greatly bitter and cold, vigorously drains lung pathogens. Delay risks pus formation and death.
