伙人叶殿和，庚寅秋患感，旬日后，汗出昏瞀，医皆束手。乃甥余薇恒挽孟英勘之，曰∶此真阴
素亏，过服升散，与仲圣“少阴误发汗”同例，下竭则上厥，岂能引亡阳为比，而以附、桂速其毙耶？以∶元
参地黄 知母 甘草 白芍 黄连 茯苓 小麦 龟板 鳖甲 牡蛎 驴皮胶，为大剂投之，得愈。
家叔南山，于秋间患感，日治日剧，渐至神昏谵妄，肢震动惕。施、陈两医，皆谓元虚欲脱，议投峻
补。家慈闻而疑之曰∶盍与孟英商之。孟英诊曰∶无恐也，通络蠲痰，可以即愈。用∶石菖蒲 羚羊角 丝瓜
络冬瓜子 苡仁 桑枝 橘络 旋复 葱须 贝母 钩藤 胆星为剂，化服
万氏牛黄清心丸一颗，覆杯而安，调理半月而愈。
段春木，秋杪患发热，而腰痛、腿痛如刀割。孟英视之，略不红肿，脉至细数，苔色黑燥，溺赤便黑。予∶
西洋参 麦冬 生地 犀角 银花 楝实 石斛 知母 甘草 竹沥 蔗汁，为大剂。投之，热渐退，痛渐已。
惟舌绛无津，故仍与甘凉濡润为方，数日后，忽舌绛倍加，燥及咽膈，水饮不能下咽。孟英曰∶真阴涸竭，药
难奏绩矣。然窃疑其何以小愈之后，骤尔真阴涸竭，或者背余而服别药乎？继其契友来询云∶段死而舌出，此曷
故欤？孟英闻之，爽然大悟。因撷《伤寒》（瘥后）女劳复之文示之。其人顿足云∶良
然。彼于小愈后，曾宿于外，次日归，即转剧。苟直陈不讳，或尚可活乎？孟英曰∶未必然也。烧 散、鼠矢

虚一实有定论，不致混同而治矣。
伙计叶殿和，在庚寅年秋天患了外感病，十几天后出现出汗、神志昏蒙的症状，医生们都束手无策。于是他的外甥余薇恒请王孟英来诊治。王孟英说：“这是真阴素来亏虚，又过度服用了升提发散的药物，这与张仲景所说的‘少阴病误用发汗法’属于同一类情况。下焦精气枯竭导致上焦阳气厥逆，怎么能引用亡阳证来类比，而使用附子、肉桂等药加速其死亡呢？”于是开具大剂量的方药：元参、地黄、知母、甘草、白芍、黄连、茯苓、小麦、龟板、鳖甲、牡蛎、驴皮胶，服用后痊愈。
我的叔父南山，在秋季患外感病，每天治疗病情却加重，逐渐发展到神志昏迷、胡言乱语，肢体震颤动摇。施姓和陈姓两位医生，都认为是元气虚弱即将脱失，商议投用峻猛的补益药物。家母听说后表示怀疑，说：“何不和王孟英商量一下。”王孟英诊脉后说：“不必担心，通过通络化痰的方法，可以很快痊愈。”使用的方药是：石菖蒲、羚羊角、丝瓜络、冬瓜子、薏苡仁、桑枝、橘络、旋覆花、葱须、贝母、钩藤、胆南星为剂，并化服一颗万氏牛黄清心丸，喝完药不久便安定下来，经过半个月调理后痊愈。
段春木，在秋末患了发热，同时伴有腰痛、腿痛如刀割一般。王孟英查看患处，并没有红肿现象，脉象细数，舌苔黑而干燥，小便赤红，大便黑色。给予大剂量方药：西洋参、麦冬、生地、犀角、银花、楝实、石斛、知母、甘草、竹沥、蔗汁。服药后，热势逐渐消退，疼痛也逐渐停止。只是舌头呈现深红色且没有津液，所以仍然给予甘凉濡润的方药。几天后，突然舌色更加深绛，干燥蔓延至咽喉和胸膈，连水饮都无法咽下。王孟英说：“真阴已经枯竭耗尽，药物难以奏效了。但我私下怀疑为什么在小愈之后，真阴会突然枯竭耗尽，难道是背着我在外面服用了其他药物吗？”接着他的朋友前来询问说：“段某死后舌头伸出，这是什么缘故呢？”王孟英听后恍然大悟。于是摘录《伤寒论》中关于“瘥后”（病愈后）女劳复的条文给他看。那人跺脚说：“确实是这样。他在小愈之后，曾在外面留宿，第二天回来，病情就立刻转重。如果当初直说不讳，或许还可以救活吧？”王孟英说：“也不一定。烧裈散、鼠矢汤，都是从足少阴肾经来驱逐邪气的。他不过是热邪侵入这条经脉，也就是所谓的‘阴阳易’。现在他没有少腹绞痛的痛苦，原本就不是别人的病转移到了我身上。这确实是女劳复，导致真阴枯涸，还有什么药能迅速恢复真阴呢？然而从此以后，对于‘女劳复’与‘阴阳易’，一虚一实有了定论，不会再混淆而治了。”
Ye Dianhe, a shop assistant, contracted an exogenous pathogen in the autumn of the Gengyin year. Ten days later, he presented with sweating and mental confusion (Hunmao). Physicians were at a loss. His nephew, Yu Weiheng, invited Wang Mengying to examine him. Wang said: "This is a case of inherent deficiency of True Yin (Zhen Yin), exacerbated by excessive use of ascending and dispersing herbs. It follows the same pattern as Zhang Zhongjing's description of 'misapplied sweating therapy in Shaoyin disease'. When the lower jiao essence is depleted, upper yang becomes inverted. How can this be compared to Yang collapse (Wang Yang) and treated with Aconite (Fuzi) and Cinnamon Twig (Guizhi), which would only hasten death?" He prescribed a large dose of: Scrophulariae Radix (Yuanshen), Rehmanniae Radix Preparata (Dihuang), Anemarrhenae Rhizoma (Zhimu), Glycyrrhizae Radix et Rhizoma (Gancao), Paeoniae Radix Alba (Baishao), Coptidis Rhizoma (Huanglian), Poria (Fuling), Triticum Semen (Xiaomai), Testudinis Carapax et Plastrum (Guiban), Trionycis Carapax (Biejia), Ostreae Concha (Muli), and Asini Corii Colla (Lvpijiao). The patient recovered.
My uncle, Nanshan, contracted an exogenous pathogen in autumn. Despite daily treatment, his condition worsened progressively until he suffered from coma, delirium, and tremors/twitching of limbs. Doctors Shi and Chen both diagnosed it as critical deficiency of Yuan Qi with impending collapse, proposing the use of potent tonifying formulas. My mother doubted this and suggested consulting Wang Mengying. Wang examined the pulse and said: "Do not worry. Unblocking collaterals and eliminating phlegm will lead to recovery." He prescribed: Acori Tatarinowii Rhizoma (Shichangpu), Cornu Saigae Tataricae (Lingyangjiao), Luffae Fructus Retinervus (Sigualuo), Benincasae Semen (Dongguazi), Coicis Semen (Yiren), Mori Ramulus (Sangzhi), Citri Reticulatae Pericarpium Viride (Jieluo), Inulae Flos (Xuanfu), Allii Fistulosi Bulbus (Congxu), Fritillariae Thunbergii Bulbus (Beimu), Uncariae Ramulus cum Uncis (Gouteng), and Asteris Radix et Rhizoma Praeparatum cum Fel Tapis (Danning) as a decoction, along with one pill of Wan Shi's Niuhuang Qingxin Wan dissolved for administration. The patient stabilized shortly after taking the medicine and recovered after half a month of convalescence.
Duan Chunmu suffered from fever in late autumn, accompanied by severe lumbar and leg pain described as knife-like cutting. Wang observed no redness or swelling. The pulse was fine and rapid; the tongue coating was black and dry; urination was reddish, and stool was black. He prescribed a large dose of: Panax Ginseng Caudex Americanus (Yangshengshen), Ophiopogonis Radix (Maidong), Rehmanniae Radix (Shengdi), Rhinocerotis Cornu (Xijiao), Lonicerae Japonicae Flos (Yinhua), Meliae Fructus (Lianshi), Dendrobii Caulis (Shihu), Anemarrhenae Rhizoma (Zhimu), Glycyrrhizae Radix et Rhizoma (Gancao), Phyllostachyris Succus (Zhuli), and Sacchari Sinarum Sucus (Zheshi). The fever gradually subsided, and the pain ceased. However, the tongue remained crimson without fluids. Therefore, he continued prescribing sweet-cool moistening formulas. Several days later, the tongue became deeply crimson, dryness spread to the throat and chest diaphragm, making swallowing even water impossible. Wang stated: "True Yin has been exhausted; medication is unlikely to succeed. I suspect that after slight improvement, True Yin suddenly collapsed, possibly due to taking other medications secretly." Later, a friend came to inquire: "Duan died with his tongue protruding. What is the reason?" Wang suddenly realized the truth. He showed the friend the passage on "female labor relapse" (Nü Laofu) after recovery from febrile diseases in the *Shanghan Lun*. The friend stamped his foot and said: "Indeed. After slight improvement, he stayed out overnight. Upon returning the next day, the condition worsened drastically. If he had confessed frankly, perhaps he could have been saved?" Wang replied: "Not necessarily. Shaokun San (Burnt Underwear Powder) and Shushi Tang (Rat Dropping Decoction) expel pathogens via the Foot-Shaoyin Kidney meridian. His condition was merely heat pathogens invading this meridian, known as 'Yin-Yang Exchange' (Yinyang Yi). Currently, he lacks the cramping pain in the lower abdomen, indicating the illness did not transfer from another person. This is truly 'female labor relapse', causing exhaustion of True Yin. What medicine could rapidly restore such depleted True Yin? However, from now on, there is a definitive distinction between 'female labor relapse' and 'Yin-Yang Exchange'—one being deficiency and the other excess—preventing them from being confused and treated identically."
