温热病者，乃感春温夏热之邪为病，发于三、四、五、六月间，俗呼为伤寒者是也。按仲淳云∶
伤寒时疫诸病，兼阳明症者独多。故一见潮热自汗，喜凉恶热，烦躁饮冷，舌苔谵语，发厥斑狂，
脉洪大者，急宜白虎汤加竹叶、麦冬，解热生津止渴；势甚者，大剂连投，诸症自平。若夏月中
暑，汗出恶寒，身热而渴，脉虚者，但于白虎加参治之，本草载石膏起死回生，功同金液，少则
难效，世医不解，兹特表出。仲景于伤寒后，虚羸少气，气逆欲吐者，尚用石膏，以其甘寒，不比
苦寒之伤胃气耳。忠可谓今人不忌芩、连，而但畏石膏，岂其有白虎之称耶！噫！愚哉！夫白虎西
方金神也，秋金之令行，则夏火之炎熄；方名白虎者，欲其行清肃之令而除热，非谓其如虎之猛
而伤人也。试观喻、李立论，最重温补，仲淳用药，极称拘谨，凡遇前症，皆用是方。余因先大人
热病，而为庸医投参、附所杀，
感于玄晏之言，而精研斯道者凡三十年。后得备员医院，见诸名家投此辄应，余亦治经多人，
凡患阳明症者，是剂效难枚举。如缵功汪先生，感时疾，召诊。见阳明症具，因立白虎方，
每剂用石膏三两，二剂热症顿减。吾乡著名世医骇谓遍身冷汗，肢冷发呃，非参、附不克回阳
，诸医和之众议白虎再投必毙，余引仲景热深厥亦深之文，及嘉言阳症忽变阴厥，万中无一之
说，吴论阴症为世间罕有之病。呃逆亦胃热所致，若拘冷呃之名，而投热剂，误人不浅。谆谆力
辨，固执不从。迨彼投参、附回阳敛汗之剂，汗益多而体益冷。反诋白虎之害。微阳脱在旦暮
，势甚危急，举家惊惶，复来索治。余全罔顾，仍用白虎。嘱其使者，暗投石膏三
两，大剂二服，汗止身温。仍用前汤加减，数服方痊。由是观之，全由白虎之回生也。昔嘉言辨虚
人伤寒，汗、下、和解药中，有不宜用参之言误人者，死入犁耕地狱。余谓今后温热病中遇渴欲饮冷
之症，有谓不可用石膏者，亦死入犁耕地狱。嘉言谓伤寒不当用参而用之杀人者，皆是与 、术、

，所以东垣有垂戒之条。人不细审，畏用石膏，且谓吾遵东垣尚王道，泥执人病十有九虚，临症惟是
温补之说，毋论外感内伤，寒热虚实，概投参、 、归、附，甚至加干姜、附、桂，致轻者重，重者

若真阳不足之症，千百中一、二而已。乃盲师不察，概投温补，益助阳劫阴，以致咽痛喉烂，音哑声嘶

温热病，是指感受春季温暖、夏季炎热之邪气而引发的疾病，多发于三、四、五、六月间，世俗之人常将其误称为“伤寒”。据仲淳所言：
伤寒与时疫等各类疾病中，兼有阳明症（阳明经受邪所致的病证）的情况最为多见。因此，一旦见到潮热（定时发热）、自汗（不因活动而自然出汗）、喜凉恶热、烦躁不安、想喝冷水、舌苔异常、胡言乱语、四肢厥冷、出现斑疹或狂躁等症状，且脉象洪大者，应立即使用白虎汤加竹叶、麦冬，以清热生津止渴；若病情严重，可大剂量连续服用，诸症自然平息。如果是夏季中暑，表现为出汗、怕冷、身体发热且口渴，脉象虚软者，只需在白虎汤基础上加入人参治疗即可。本草记载石膏具有起死回生的功效，作用如同金液，用量过少则难以见效，世间的医生不懂这个道理，特此指出。张仲景在《伤寒论》中提到，伤寒后出现身体虚弱消瘦、气短、气逆想呕吐的情况，尚且使用石膏，是因为石膏性味甘寒，不同于苦寒药物会损伤胃气。可笑的是，如今的人不忌讳黄芩、黄连的苦寒，却唯独畏惧石膏，这难道符合“白虎”这一名称的含义吗？唉！真是愚昧啊！白虎是西方金神，当秋季金气当令时，夏季的火热之气就会熄灭；方剂命名为“白虎”，意在取其行清肃之令以清除热邪，并非指其像老虎一样猛烈而伤害人体。试看喻嘉言、李中梓等人的立论，最重视温补疗法，仲淳用药极为谨慎拘谨，凡是遇到上述前症，都使用此方。我因为先父患热病，被庸医投用参、附子等药致死，受王叔和（玄晏）言论的感触，于是精研医学之道三十年。后来我在医院任职，看到各位名医使用此方往往奏效，我也治疗了许多人，凡是患有阳明症的患者，使用该方剂的疗效难以一一列举。例如缵功汪先生，感染时疾，请我诊治。见其具备阳明症的全部表现，便开具白虎方，每剂使用石膏三两，服用两剂后热症顿时减轻。我们乡里著名的世医惊骇地说：“遍身冷汗，四肢冰冷打呃，不用参、附子无法回阳救逆。”众多医生附和，认为再投白虎汤必死无疑。我引用张仲景“热深厥亦深”的理论，以及嘉言关于“阳症突然变为阴厥，万中无一”的说法，还有吴又可论述“阴症是世间罕见的疾病”的观点。打呃也是胃热所致，如果拘泥于“冷呃”的名称，而投用热性药剂，误人不浅。我谆谆告诫并极力辩驳，但他们固执不听。等到他们投用参、附子回阳敛汗的药剂后，汗水更多，身体更冷，反而诋毁白虎汤的危害。此时微弱的阳气即将脱失，形势非常危急，全家惊慌失措，再次来求治。我完全不顾他们的反对，仍然使用白虎汤。嘱咐他们的使者，暗中投喂石膏三两，大剂量服用两次，汗水停止，身体回暖。随后仍用前方加减，服用数次后痊愈。由此看来，完全是靠白虎汤起死回生。过去嘉言辨析虚人伤寒，在汗法、下法、和解药中，有不宜用人参的说法，结果误人性命，他说这样的人死后要犁耕地狱。我认为今后温热病患者中出现口渴想喝冷水症状时，若有说不可使用石膏的，也应当死入犁耕地狱。嘉言认为伤寒不当用人参而用了导致杀人的，都是与苍术、白术、当归、干姜、附子、桂枝同用温补的错误所致。我认为不当用白虎汤而用了导致杀人的，乃是症状看似白虎汤证，只有失血患者才有的情况，所以李东垣有垂戒的条文。人们不仔细审察，畏惧使用石膏，并且声称自己遵循李东垣的王道医术，固执地认为病人十有九个是虚证，临症只是采用温补之说，不论外感内伤，寒热虚实，一概投用参、苍术、白术、当归、附子，甚至加上干姜、附子、桂枝，导致轻病加重，重病死亡。常见服用热药后，口干舌燥，咽喉疼痛，牙齿疼痛，烦躁不安，甚至眼睛发红，面色红润，舌头僵硬，嘴唇开裂，筋脉跳动，肌肉抽动，各种孔窍出血，还说是虚阳上浮，加大剂量催逼，实在可悲悯。更有因房事劳累而患病的一种症状，嘉言认为世上没有不被“阴症”之名迷惑的，往往投用热药，促使患者暴亡，却推卸说是阴极无法救治，致使冤鬼夜间号哭，全然不悔悟，不知道杀人何时才能停止。又如虚劳内热，骨蒸盗汗，咳嗽吐痰，失血等症状，都是由肾水不足所致。所以王节斋说：“因水虚成病的，十之八九；因火虚成劳的，百无一二。”仲淳认为世上的病人，阴虚者很多，若是真阳不足的病症，千百中只有一两个而已。然而盲从的医生不加考察，一概投用温补，更加助长阳气劫夺阴液，以致咽喉疼痛腐烂，声音嘶哑而死。难怪嘉言发出“天生庸医，不用动刀就在沿街屠戮”的感叹。我亲眼目睹，心中伤痛，年老时得了一点光明，曾编纂《医镜》一书，希望挽回风气。现在因为众医排斥白虎汤而推崇桂枝、附子，所以不得已先将其刊印出版。我思考三吴地区是人文荟萃之地，岂会缺乏高贤，无需我多嘴。对于偏执的一类人，倘若看到这种说法，肯留心关注，未必不能对世人有所补益。有人问：“你既然不行道，又不是争名夺利，为何贬低别人抬高自己这么深，岂不是会被众人愤怒吗！”这是你说我喜欢用白虎汤，而讨厌别人用附子、桂枝。附子、桂枝也有起死回生的功效，而白虎汤也未必不是杀人的药剂，你为何指责得这么深呢？我说：是的，曾听说张景岳说：“我只知道有黄帝岐伯，而不知道有其他诸子；只知道有好生之德，而不知道有避讳。这就是我之所以进行这番辩论的原因，了解我还是怪罪我，我都不计较。”如果说你喜欢谈论白虎汤而厌恶附子、桂枝，那就错了。古话说：“药不拘泥于方剂，合适即可使用。”所以有什么病就用什么药，病千变万化，药也随之千变万化。难道有属于虚寒的病症，可以舍弃附子、桂枝而投用白虎汤吗？所以附子、桂枝原本不是杀人的药，也取决于如何使用罢了。以前我的宗族叔父小谢公的老婶得了外科病症，一百天内用人参十余斤，这又将被人说成是喜欢用人参了。唉！医道的难言之处在如此。太史朱慎斋说：“具备经史之才，阐发岐黄之学，理应独出心裁，妙手回春。中原地区的扁鹊，确实值得赠送。”太史冯方寅说：“医生不执着于固定方剂，必须随症延请医生，以救济危重病人。现在的医生，不辨别阴阳，不分虚实，不区别寒热，任性自用，动不动就以参、附子为先锋，往往将人陷入危险而不悔改，这难道是卢医、扁鹊的宗旨吗？松园独自能排除众议，挽救危局为平安，直接揭露妄用参、附子的罪行。我也患痢疾，几乎遭受其毒害，所以写书赠给他。”少宗伯宋彦公说：“我在京城时，就听闻松兄的大名，等到我女婿顺思患弱症，众医都认为是不治的败症，而松兄独自认为是假象容易医治。次年春天，女婿巽昭也患此病，众医都认为阳虚可愈，而松兄独自认为是真阴疲惫，无法救治。此后都应验了。如果不是辨证十分明彻，怎么能做到这样。每次观看松兄用药治病，似乎与病症相反，但究其实质却适宜，像这样的案例很多，因此名声不虚传。”国医贺右廉说：“医生不选择固定方剂，合适即可使用。切恨世俗庸流，往往拘泥于辛温峻补，见到使用寒凉药，就加以私议，使病人害怕而不用，于是妄施平淡的药剂。日复一日，以至于垂危，即使是智者也不能救治，这样治死的占十分之五，而且毫不感到羞耻悲哀！松兄学问渊博，识见过人，这篇论述确实是中流砥柱。”明经外翰王雪巢说：“松翁年轻时以秀才身份在考场闻名，不久以二守身份供奉医院，请求归乡著书。亲友知道他神奇而索取他的方子，大多与他意见相左，不理解就诽谤，然而使用辄有效，像前面的案例很多。观看这篇论述使用白虎汤及告诫一概投用热剂，剖析详细明了，即使聋聩之人也能清醒，真是济世的津梁。”孝廉女婿程亦可说：“这是关乎身命的著作，应当放在座右，不要遭受毒手。”
Warm-heat diseases refer to illnesses caused by pathogenic factors of spring warmth and summer heat, occurring mainly in the third, fourth, and fifth months (lunar calendar). The common people often mistakenly call them "Shanghan" (Cold Damage). According to Zhongchun:
Among various diseases such as Shanghan and epidemic febrile diseases, those presenting with Yangming syndrome are particularly numerous. Therefore, once tidal fever (fever that occurs at regular intervals), spontaneous sweating, preference for coolness and aversion to heat, irritability, desire to drink cold water, abnormal tongue coating, delirium, cold extremities, appearance of macules or mania, and a flooding pulse are observed, Baihu Tang (White Tiger Decoction) should be administered urgently, added with Zhu Ye (Bamboo Leaf) and Maidong (Ophiopogon Tuber), to clear heat, generate fluids, and relieve thirst. If the condition is severe, large doses can be administered continuously, and all symptoms will naturally subside. In cases of heatstroke during summer, characterized by sweating, aversion to cold, body heat, thirst, and a deficient pulse, treatment should consist solely of Baihu Tang added with Renshen (Ginseng). Materia Medica records that Shigao (Gypsum Fibrosum) has the power to revive the dying, functioning similarly to "Golden Liquid"; if the dosage is too low, it is difficult to achieve efficacy. Physicians of the world do not understand this, so I specifically point it out. Zhang Zhongjing, in his treatise on Shanghan, mentioned that after Shanghan, when patients present with emaciation, shortness of breath, and rebellious qi causing nausea, Shigao is still used because its sweet and cold nature differs from bitter-cold herbs that damage stomach qi. It is laughable that nowadays people do not fear the bitterness and cold of Huangqin (Scutellaria Root) and Lianzi (Lotus Seed) or Lianhua (Lotus Flower), but only fear Shigao. Does this align with the name "Baihu" (White Tiger)? Alas! How ignorant! Baihu represents the Metal Spirit of the West; when the command of Autumn Metal prevails, the inflammation of Summer Fire is extinguished. The formula is named "Baihu" to signify its function of executing a clearing and肃ifying (purifying/descending) command to remove heat, not implying that it is fierce like a tiger and harmful to humans. Consider the theories of Yu Jiayan and Li Zhongzi, who most valued warm-tonic therapies, and Zhongchun, who was extremely cautious in prescribing. For all the aforementioned conditions, they all used this formula. Because my late father died of a heat disease due to being prescribed Renshen and Fuzi (Aconite Root) by quacks, and influenced by the words of Wang Xuan'yan (Wang Shuhe), I have meticulously studied this field for thirty years. Later, while serving in a hospital, I saw that famous physicians using this formula often achieved results. I also treated many patients; for those suffering from Yangming syndrome, the efficacy of this prescription is too numerous to list. For example, Mr. Zanguan Wang contracted an epidemic disease and summoned me for diagnosis. Observing that he exhibited all signs of Yangming syndrome, I prescribed Baihu Tang, using three liang of Shigao per dose. After two doses, the heat symptoms decreased drastically. Famous hereditary physicians in our hometown were horrified, stating, "With cold sweat all over the body, cold limbs, and hiccups, only Renshen and Fuzi can restore yang." Many doctors concurred, arguing that administering Baihu Tang again would certainly lead to death. I cited Zhang Zhongjing's text "the deeper the heat, the deeper the cold extremities," Jiayan's statement that "yang syndromes suddenly transforming into yin cold extremities occur in one in ten thousand," and Wu Keyi's argument that "yin syndromes are rare diseases in the world." Hiccups are also caused by stomach heat. If one adheres to the name "cold hiccups" and administers hot-natured agents, the error is profound. I earnestly argued and strongly refuted their views, but they remained obstinate. When they finally administered agents containing Renshen and Fuzi to restore yang and stop sweating, the sweating increased, and the body became colder. They then blamed the harm of Baihu Tang. At this point, the faint yang qi was on the verge of collapse, and the situation was critical. The whole family was panicked and came to seek treatment again. I disregarded their objections entirely and continued to use Baihu Tang. I instructed their messenger to secretly administer three liang of Shigao, giving two large doses. The sweating stopped, and the body warmed up. Subsequently, I used the previous decoction with modifications. After several doses, he recovered. From this, it is evident that it was entirely due to Baihu Tang reviving him. Previously, Jiayan analyzed Shanghan in deficient individuals, stating that in sweating, purging, and harmonizing prescriptions, Renshen should not be used. He said those who err in this way deserve to plow hell upon death. I believe that henceforth, in warm-heat diseases, if patients present with thirst and a desire to drink cold water, anyone who claims Shigao should not be used deserves to plow hell. Jiayan stated that those who kill by using Renshen for Shanghan when inappropriate did so because they combined it with Cangzhu (Atractylodes Rhizome), Baizhu (Atractylodes Macrocephala Rhizome), Danggui (Angelica Sinensis Root), Ganjiang (Dried Ginger), Fuzi, and Guizhi (Cinnamon Twig) for warm-tonic purposes. I argue that those who kill by using Baihu Tang when inappropriate are dealing with conditions that merely resemble Baihu Tang patterns, which occur only in patients with blood loss. Hence, Li Dongyuan issued warnings. People fail to examine carefully, fear using Shigao, and claim they follow Li Dongyuan's "Kingly Way," stubbornly believing that nine out of ten patients are deficient. In clinical practice, they only employ warm-tonic methods, regardless of exterior or interior, excess or deficiency, cold or heat, indiscriminately administering Renshen, Cangzhu, Baizhu, Danggui, and Fuzi, even adding Ganjiang, Fuzi, and Guizhi. This causes mild conditions to become severe and severe ones to result in death. I frequently see patients taking hot medicines develop dry mouth and tongue, sore throat, toothache, restlessness, red eyes, ruddy complexion, stiff tongue, cracked lips, twitching tendons, moving muscles, and bleeding from orifices. Yet, they attribute this to floating deficient yang and increase the dosage, which is truly pitiable. Furthermore, there is a condition caused by sexual exhaustion. Jiayan noted that the world is often confused by the name "yin syndrome," often administering hot medicines that hasten sudden death, yet blaming it on "extreme yin being incurable," causing ghosts to wail at night without repentance, unaware of where the killing will end. Similarly, internal heat from deficiency labor, bone-steaming night sweats, coughing with phlegm, and blood loss are all caused by insufficiency of Kidney Water. Thus, Wang Jiezhai said: "Nine or ten out of ten illnesses are caused by water deficiency; one or two out of a hundred are caused by fire deficiency leading to consumption." Zhongchun believed that among modern patients, yin deficiency is very common, whereas true yang insufficiency accounts for only one or two in a thousand. However, blind physicians fail to observe and indiscriminately administer warm tonics, further assisting yang and robbing yin, leading to sore throat, rotting gums, hoarseness, and death. No wonder Jiayan sighed, "Nature creates quack doctors who slaughter door-to-door without wielding a knife." I witnessed this with heartbreak. In my old age, gaining some clarity, I compiled the *Yi Jing* (Mirror of Medicine) hoping to reverse the trend. Now, since many physicians reject Baihu Tang and revere Guizhi and Fuzi, I have no choice but to publish this first. I reflect that Sanwu is a hub of culture and literature; surely there are high sages there, making my additions unnecessary. For those with biased views, if they read this and pay attention, it may not fail to benefit the world. Someone asked, "Since you do not propagate your Dao and are not competing for fame or profit, why do you criticize others and praise yourself so deeply? Will you not anger the masses?" You imply that I prefer Baihu Tang and dislike Fuzi and Guizhi. Fuzi and Guizhi also have the power to revive the dying, and Baihu Tang is not necessarily a killing agent. Why do you criticize so severely? I replied, "Indeed. I once heard Zhang Jingyue say: 'I know only of Huangdi and Qibo, not of other masters; I know only of loving life, not of avoiding taboos.' This is why I made this distinction. Whether they understand or blame me, I do not care." To say that I like Baihu Tang and dislike Fuzi and Guizhi is incorrect. As the ancients said, "Medicines are not bound by formulas; use what is appropriate." Therefore, use medicine according to the disease. Diseases change in thousands of ways, and so do medicines. Could there be a deficiency-cold pattern where one abandons Fuzi and Guizhi to use Baihu Tang? Thus, Fuzi and Guizhi are originally not killing drugs; it depends on how they are used. Previously, my clan uncle Xiao Xie Gong's elderly aunt suffered from a surgical condition and consumed more than ten jin of Renshen in a hundred days. This would again be cited as proof that I favor Renshen. Alas! The difficulty of discussing medical principles is thus. Grand Historian Zhu Shenzhai said: "Possessing talent in classics and history, elucidating the learning of Qi and Huang, one ought to have unique insights and bring spring back under the hands [heal]. The Bian Que of the Central Plains is indeed worthy of gift." Grand Historian Feng Fangyin said: "Physicians should not stick to fixed formulas but must follow symptoms to save critical patients. Today's physicians do not distinguish yin and yang, excess and deficiency, cold and heat, acting arbitrarily, often using Renshen and Fuzi as vanguard, frequently endangering patients without remorse. Is this the intent of Lu and Bian? Song Yuan alone could refute public opinion, turn danger into safety, and directly expose the crimes of reckless use of Renshen and Fuzi. I also suffered from dysentery and nearly fell victim to such treatments, so I wrote this book to present to him." Vice Minister of Personnel Song Yiangong said: "When I was in the capital, I already heard of Brother Song's great reputation. Later, when my son-in-law Sun Si suffered from a weak condition, all physicians considered it a terminal, untreatable case, but Brother Song alone said it was a false image easy to treat. The following spring, my son-in-law Xun Zhao also suffered from this disease. All physicians believed yang deficiency could be cured, but Brother Song alone said true yin was exhausted and incurable. Both predictions proved correct. If differentiation of symptoms were not extremely clear, how could this be achieved? Every time I observe Brother Song treating diseases with medicine, it seems contrary to the symptoms but turns out to be appropriate. There are many such cases, hence his reputation is well-deserved." National Physician He Youlian said: "Physicians do not select fixed formulas; they use what is appropriate. I deeply hate vulgar quacks who stick to pungent-warm drastic tonics. When seeing cold-clearing medicines used, they add private criticisms, making patients afraid to use them, thus resorting to bland agents day after day until the patient is critical, beyond even the saving power of the wise. Such negligence kills five out of ten, yet they feel no shame or sorrow! Brother Song's scholarship is profound, and his insight surpasses others. This discussion is truly a pillar in midstream." Mingjing Hanlin Academician Wang Xuetao said: "In his youth, Song Weng gained fame in examinations as a student member. Later, serving as Ershou in the Imperial Hospital, he requested leave to write books. Relatives and friends sought his prescriptions knowing his miraculous skills, but many disagreed with him, slandered him when they didn't understand, yet his prescriptions were effective. There are many such cases. Reading this discussion on using Baihu Tang and warning against indiscriminate hot agents, the analysis is detailed and clear, awakening even the deaf and confused. It is truly a ferry crossing for saving the world." Xiaolian Son-in-law Cheng Yike said: "This work concerns life and death; it should be placed beside the bed to avoid toxic hands."
