孟英曰∶阴虚液燥，津不易生，虽求其泄，不可得也，乌可拘泥一偏，而不知通变哉？仍以前法，去杏仁、贝母、
花粉，加知母、百合、合欢（皮）为方，并嘱另邀老医朱嵩年敷治其外。如法施之，果渐向安。久之，当脐痂落，如

石芷卿，突然患上腹部胀满，十几天后，肚脐处流出脓液。外科医生将其视为肠痈（肠道化脓性炎症），给予温补和托毒外出的药物。随后出现咳嗽、失眠，腹中剧烈绞痛，痰色红绿相间，大便不通畅。于是请孟英商议诊治。脉象弦细而数，舌质深红且极度口渴。孟英说：观察脉候，这是真阴（肾阴）严重亏损的证候。附子、肉桂、当归、白术都是禁忌的药物。使用甘露饮（滋阴清热方剂）加入西洋参、天花粉、贝母、杏仁、冬瓜子投服，痰咳随即安定。但外科医生认为此病最忌讳腹泻，润燥药不宜多服。孟英说：阴虚液燥，津液难以生成，即使想让它腹泻，也不可能做到，怎么能拘泥于片面之见，而不懂得变通呢？仍然用前面的方法，去掉杏仁、贝母、花粉，加入知母、百合、合欢皮作为处方，并嘱咐另外邀请老医生朱嵩年在外敷治。按照这种方法施治，果然逐渐好转。久而久之，当脐处的结痂脱落，像小儿断脐带留下的带状痕迹一样，脐内新肉晶莹光亮而痊愈。
吴芸阁，因为在壮年时患梅毒疮，过量服用寒凉性质的药物，疮虽然好了，但阳气受损，引发虚寒病症，改为投用温补药物如金液丹、大造丸之类，才得以安宁。无奈医生不明白药物是为了纠正偏颇、补救弊端而设立的，漫无节制，习以为常，逐渐导致血从上溢（吐血或衄血），便泻在下，食欲减少痰多，气喘逆乱难以卧睡，两脚不能屈伸。童某医生仍认为是寒湿为患，进服苓姜术桂汤多剂，病情更加严重，而且小便逐渐减少且颜色绿如胆汁，其他医生都不明白其中的缘故。延请孟英诊治，脉象弦硬无神。孟英说：从前寒凉药物残害阳气，现在热性药物耗竭阴液了。胃中的津液，都被灼烧煎熬成为痰，五脏都失去滋养，从而出现上述症状，水源即将枯竭，小便自然逐渐减少；木火在内焚烧，显露出东方（肝属木，其色青/绿）的颜色，这与章虚谷所治疗的暑邪结于厥阴经，用来复丹攻逐邪气从尿排出而见到深碧色的情况相同，然而彼证属实，此证属虚，相差如天地之别，恐怕即使是华佗再生，也难以有力挽狂澜之力了，不久果然去世。
Shi Zhiqing suddenly suffered from abdominal distension. Ten days later, pus discharged from the umbilicus. The surgeons diagnosed it as Changyong (Intestinal Abscess) and administered warming and tonifying medicines to support the interior and expel toxins. Consequently, he developed coughing, insomnia, severe colic in the abdomen, red-and-green sputum, and constipation. He then invited Mengying for consultation. The pulse was wiry, fine, and rapid; the tongue was crimson with extreme thirst. Mengying stated: "Observing the pulse and signs, this is a syndrome of severe deficiency of True Yin (Kidney Yin). Fuzi (Aconite Root), Rougui (Cinnamon Bark), Danggui (Angelica Sinensis), and Baizhu (Atractylodes Macrocephala Rhizome) are all contraindicated." He prescribed Ganlu Yin (Sweet Dew Decoction) supplemented with Xiyangshen (American Ginseng), Huafen (Trichosanthes Root), Beimu (Fritillaria Bulb), Xingren (Apricot Seed), and Dongguazi (Winter Melon Seed). After administration, the cough and sputum immediately subsided. However, the surgeons argued that this disease strictly forbids diarrhea and that moistening drugs should not be taken in large quantities. Mengying replied: "With Yin deficiency and fluid dryness, body fluids are difficult to generate. Even if one sought to induce diarrhea, it would be impossible. How can one adhere to a partial view without understanding flexibility?" He continued with the previous method, removing Xingren, Beimu, and Huafen, and adding Zhimu (Anemarrhena Rhizome), Baihe (Lily Bulb), and Hehuanpi (Albizia Bark) to the prescription. He also advised inviting the elderly physician Zhu Songnian for external treatment. Following this regimen, the condition gradually improved. Over time, the scab at the umbilicus fell off like a band left after an infant's umbilical cord separation, and the new flesh inside the umbilicus became bright and healthy, leading to recovery.
Wu Yunge had suffered from Meichuang (Syphilitic Chancre) during his prime years. Having overused cold-natured medicines, although the sores healed, his Yang Qi was damaged, giving rise to deficiency-cold syndromes. He switched to warming and tonifying medicines such as Jin Ye Dan (Golden Elixir Pill) and Da Zao Wan (Great Creation Pill), which brought temporary relief. Unfortunately, physicians failed to understand that medicines are designed to correct imbalances and remedy defects. They administered them without restraint, making it a routine practice. This eventually led to bleeding from above (hematemesis or epistaxis), diarrhea below, reduced appetite with excessive phlegm, wheezing and rebellious Qi preventing lying down, and inability to flex and extend both legs. Tong, another physician, still attributed the condition to Cold-Dampness and prescribed Ling Jiang Zhu Gui Tang (Poria, Ginger, Atractylodes, and Cinnamon Decoction) repeatedly, exacerbating the condition. Furthermore, urination decreased in volume and turned green like bile juice. Other physicians could not discern the cause. Mengying was invited to diagnose. The pulse was wiry, hard, and devoid of spirit. Mengying said: "Previously, cold medicines injured Yang Qi; now, hot medicines have exhausted Yin fluids. The fluids in the Stomach are scorched and transformed into phlegm. The Five Viscera lose their nourishment, resulting in the aforementioned manifestations. The source of water is drying up, hence urine naturally decreases. Wood and Fire are burning internally, revealing the color of the East (Liver belongs to Wood, its color is green/cyan). This is similar to cases treated by Zhang Xugu where Summer-Heat binds in the Jueyin channel, using Laifu Dan (Revive Life Pill) to attack pathogens via urination, resulting in dark blue-green urine. However, that case was excess, while this is deficiency; they differ as much as heaven and earth. I fear even if Hua Tuo were reborn, he might struggle to save him." Indeed, the patient died shortly thereafter.
