梅翁幼郎，夏间患感证，见其发热口干，舌苔白腻，知有伏邪，思膏粱稚子，提携捧负
，邪
何由受。询其乳媪，据云向系楼居，近缘天暑，移住地房，霉气甚重，病因此受，亦未可知
。予曰是矣。盖霉湿之气，从口鼻吸入，伏于膜原，酝酿为热，自里达表，不比风寒客于皮
毛，可以辛温发散而治也。初用淡豉、苏梗、鲜藿香、秦艽、广皮、桔梗、连翘、甘草、通
草之属，芳香解秽，辛凉透邪。服药热甚，烦渴，舌苔转黄，方除苏梗广皮，加入黄芩黑栀
赤苓泽泻，热渴不止，舌色欲焦，予素手战，渠宅视恙，方俱心树兄代书，乃谓之曰∶此证
热势炽甚，非白虎汤不能去病。心兄云∶据证应用此方，但白虎之名，俗多恐畏，或至明日
，如病不减，再进如何?予曰∶拯溺救焚，急不及待。今舌欲焦，邪热燔灼，胃津已伤，倘
到明日，舌若变黑，而成胃实。则非白虎所能胜任。再投承气，岂不更骇听闻。因将病原治
法，细与渠宅帮助。当用石膏一两，知母一钱，并加滑石芦根，其余栀芩等味，分量均照前
加重。次日复看，身热较轻，舌焦亦润。但病来势暴，若骤松手，恐其余烬复燃，仍守原方
，再服一剂，转用沙参玉竹麦冬丹皮石斛料豆梨汁芝麻，养阴需液而痊。
安波按∶读斯篇未终，不觉喟然长叹已三息矣。盖古之名汤治疾，二翻三复者甚众，
今时
地卑气薄，药未终剂，更医已数四矣。故出类拔萃之辈，常立于人背之后，是殆所谓命也夫

梅翁的小儿子，在夏季患上了外感病证。观察到他有发热、口干的症状，舌苔白而腻，判断体内有潜伏的病邪。考虑到他是吃精细食物长大的娇嫩孩童，平时被大人提携背负，病邪是如何侵入的呢？询问他的乳母，乳母说之前一直住在楼上，最近因为天气炎热，搬到了地下的房间，那里的霉湿之气很重，生病可能因此而起，这也是有可能的。我说：“说得对。”
这是因为霉湿之气从口鼻吸入，潜伏在膜原（半表半里的部位），酝酿化热，由里达表。这与风寒之邪客于皮毛不同，不能用辛温发散的方法来治疗。起初使用淡豆豉、苏梗、鲜藿香、秦艽、广陈皮、桔梗、连翘、甘草、通草这类药物，旨在芳香化浊解秽，用辛凉之法透发邪气。
服药后发热加重，出现烦躁口渴，舌苔转为黄色。于是方剂中去掉了苏梗和广陈皮，加入了黄芩、黑栀子、赤茯苓、泽泻。但热渴症状仍未停止，舌色变得像要焦枯一样。我素来手颤，当时在他家诊治病情，药方都是心树兄代写的，于是我告诉他：“这个病症的热势非常炽盛，非用白虎汤不能去除病邪。”心树兄说：“根据证候确实应该用这个方子，但‘白虎’这个名字，世俗之人多感到恐惧畏惧，或许等到明天，如果病情没有减轻，再服用如何？”我说：“这就像救溺水、救火烧一样紧急，来不及等待。现在舌苔快要焦枯，邪热燔灼，胃中的津液已经受伤，如果等到明天，舌苔变成黑色，就会形成胃实热结的证候。那时再用承气汤，岂不是更让人惊骇听闻吗？”于是我将病因和治疗法则，详细告知他家人协助准备。应当用石膏一两，知母一钱，并加入滑石、芦根，其余如栀子、黄芩等药物的分量都按照之前的剂量加重。
第二天复诊，身体发热较轻，舌苔焦枯的情况也得到滋润。但是病势来得猛烈，如果突然停药放松，恐怕残余的热邪会再次燃烧，于是仍守原方，再服用一剂。随后改用沙参、玉竹、麦冬、丹皮、石斛、料豆、梨汁、芝麻，通过滋养阴液使疾病痊愈。
安波按：读这篇医案未完，我不禁长叹了三次。古代的名方治疗疾病，经过反复推敲验证的案例很多，如今时局下地势低洼、人气薄弱，药还没吃完，就已经换了好几个医生了。所以那些出类拔萃的医生，常常站在病人的背后（意指难以施展或不被信任），这大概就是所谓的命运吧。
The youngest son of Mr. Mei suffered from an exogenous pathogenic condition (Gan Zheng) in the summer. He presented with fever and dry mouth, and a white, greasy tongue coating, indicating the presence of latent pathogens (Fu Xie). Considering he was a delicate child accustomed to refined food and being carried by adults, one might wonder how the pathogen invaded. Upon questioning the wet nurse, she stated that they previously lived on an upper floor but had recently moved to a basement room due to the hot weather, where the moldy and damp qi was heavy; it is possible the illness resulted from this exposure. I said, "That is correct."
This is because the moldy-damp qi enters through the nose and mouth, lies latent in the Mo Yuan (Membrane Source), and brews into heat, emerging from the interior to the exterior. This differs from wind-cold pathogens attacking the skin and hair, which can be treated with acrid-warm diaphoretic methods. Initially, I used herbs such as Dan Chi (Light Fermented Soybean), Su Geng (Perilla Stem), Xian Huo Xiang (Fresh Patchouli), Qin Jiao (Gentiana Macrophylla), Guang Pi (Broad-leaved Tangerine Peel), Jie Geng (Platycodon Root), Lian Qiao (Forsythia Fruit), Gan Cao (Licorice Root), and Tong Cao (Akebia Stem). The aim was to use aromatic herbs to resolve turbidity and foulness, and acrid-cool herbs to vent the pathogen.
After taking the medicine, the fever intensified, accompanied by irritability and thirst, and the tongue coating turned yellow. Therefore, Su Geng and Guang Pi were removed from the formula, and Huang Qin (Scutellaria Root), Hei Zhi Zi (Black Gardenia Fruit), Chi Ling (Red Poria), and Ze Xie (Alisma Rhizome) were added. However, the fever and thirst persisted, and the tongue color appeared as if it were about to scorch. Due to my habitual hand tremor, I visited his home to examine the patient, while Mr. Xinshu wrote the prescriptions. I told him, "The heat intensity of this condition is extremely severe; only Baihu Tang (White Tiger Decoction) can eliminate the disease." Mr. Xinshu replied, "According to the syndrome, this formula should indeed be applied. However, the name 'Baihu' causes fear and dread among common people. Perhaps we wait until tomorrow; if the illness does not subside, then we administer it, how is that?" I said, "Saving someone from drowning or fire rescue allows no time for delay. Now the tongue is nearly scorched, indicating blazing pathogenic heat and injury to Stomach fluids. If we wait until tomorrow and the tongue turns black, forming a Stomach excess pattern, then using Chengqi Tang would be even more shocking. Therefore, I will explain the etiology and treatment principles in detail to your family to assist in preparation."
One tael of Shi Gao (Gypsum Fibrosum), one qian of Zhi Mu (Anemarrhenae Rhizoma), along with Hua Shi (Talcum) and Lu Gen (Reed Rhizome), should be used. The dosages of other herbs like Zhi Zi and Huang Qin should be increased according to the previous prescription. On the next day's follow-up visit, the body heat was lighter, and the scorched tongue became moist. However, since the disease onset was sudden and violent, abruptly stopping treatment might cause residual heat to reignite. Thus, the original formula was maintained for another dose. Subsequently, Sha Shen (Glehniae Radix), Yu Zhu (Polygonati Odorati Rhizoma), Mai Dong (Ophiopogonis Tuber), Dan Pi (Moutan Cortex), Shi Hu (Dendrobii Caulis), Dou Chi (Prepared Soybean), Li Zhi (Pear Juice), and Zhi Ma (Sesame Seed) were used to nourish Yin and generate fluids, leading to recovery.
An Bo noted: Having not finished reading this case record, I could not help but sigh deeply three times. In ancient times, famous decoctions were tested and refined repeatedly to treat diseases. In current times, given the low-lying geography and thin qi, patients often change doctors several times before finishing a course of medication. Thus, outstanding physicians often find themselves standing behind their patients (implying lack of trust or support), which is perhaps what is meant by fate.
