一白喉病热证本多。寒证较少。而寒热所郁。无不有毒。此时医所以专指为疫。而用药多偏于凉也。不
知白喉少寒证。非无寒证。白喉之热证有毒。寒证亦非无毒。时医一偏之见。杀人无算。论中设为问
答。分条详辨。熟玩之自悟其谬。
一凡病必有寒热二种。非白喉独异也。是书以寒热二字为纲领。而其中又分出轻重虚实。毫无一偏之弊。
其方又无不从亲验而来。故言之最质最切。
一寒热之分。必先证书。证既认清。复参之以脉。自无遁情矣。盖言脉尚可含糊。而言证无可迁就也。古人
以切居望闻问之后。自有深义。故是书辨证最详。辨脉从略。
一是书以寒证热证寒热错杂证。分三大纲。病情万变。总不出此三者也。而三证之方。即附于后。以便寻览。
一各方皆借古人成方而加减之。无一师心者。按证寻方。皆药到病愈。切勿增
损。如有兼证。则不妨变通。至寒热错杂证。尤不易治。故方论独详。

我的外祖父尹慎徽先生博学多才，在诗词、书法和绘画方面各臻妙境。他尤其精通中医医术（岐黄术）。我背着书箱跟随他学习，对内科学、外科学、喉科以及肿疡病症，立志刻苦钻研。二十年来，各种险恶逆乱的病证，我都一一亲身经历。广泛访问并咨询各方意见，悉心讨论研究，私下认为对此深有心得。只是白喉这一病症，世间没有专门的著作，而当时从事喉科治疗的医生，对《黄帝内经》中的相关理论缺失且不加探讨，所以偶尔遇到危急情况，便茫然无法理解。即使有一两位高明的医生，也多受习惯看法束缚，有的偏重于寒证，有的偏重于热证。偏于寒或偏于热，不仅不能成为救世济人的资本，反而恰好成了杀人的利刃。我心中对此感到怜悯。在诵读之余，我便与表兄赵仲标一起，将外祖父所传授的治疗白喉病证中屡试有效的方剂，编纂成《白喉全生集》。这本书以“寒”、“热”二字为纲领，而在寒热之中又分为轻、重、虚、实。其辨证和辨脉，条理清晰，分析细致；用药和用方，则能通权达变。简明而精当，简约而完备，使人得到这本书就能解决疑难问题。我不敢声称这是良方可以济世，但也足以使危重病人起死回生。
光绪八年壬午年冬月，衡山人李纪方伦青氏在龙门山房作序。
第一条：白喉病的热证本来较多，寒证较少，但无论寒热郁结，无不带有毒性。因此时医专门将其指认为疫病，用药多偏向凉性。却不知道白喉少寒证，并非没有寒证；白喉的热证有毒，寒证也并非无毒。时医这种片面的见解，害死了无数人。书中设有问答，分条详细辨析，熟读玩味自然能领悟其谬误。
第二条：凡是疾病必有寒、热两种性质，并非只有白喉与众不同。本书以寒、热二字为纲领，其中又分出轻、重、虚、实，毫无偏颇之弊。其中的方剂都来自亲身验证，所以论述最为质朴切实。
第三条：区分寒热，必须先确认症状。症状既然认清了，再参考脉象，病情就无所遁形了。因为谈论脉象还可以含糊其辞，但谈论症状却无法迁就迎合。古人把切脉放在望、闻、问之后，自有深意。所以本书辨证最详细，辨脉较简略。
第四条：本书以寒证、热证、寒热错杂证分为三大纲。病情变化万千，总不出这三类。而这三类证候的方剂，即附在后面，以便查阅。
第五条：各方都是借用古人的成方进行加减，没有一味主观臆断的。按证寻找方剂，都能药到病除，千万不要随意增减。如果有兼夹证候，则可以灵活变通。至于寒热错杂证，尤其难以治疗，所以方论特别详细。
第六条：治疗白喉的方法，服药应当谨慎，吹药（将药物吹入咽喉）尤其要精细。如果在乡村偏僻之地，一时无法迅速获得汤药，全靠吹药来急救。时医通行的吹药，对于轻证尚可，对于重证无不延误病情。本书的吹药，也以寒证、热证、寒热错杂证分为三大纲，按证用药，无不立即见效。切不可一味随意增减。
第七条：白喉的险证、坏证，出现牙关紧闭、痰涎上涌，导致无法服药，也无法吹药的情况。治法适宜先开关窍以清除痰涎，严重时针刺各个穴位以放出恶血，疏通经络，便能立即清醒，然后再行吹药、服药即可痊愈。本书关于开关、敷贴、针刺的方法，准备得极其精详，但只要依据方法施行即可。
第八条：本书虽然专为白喉立法，然而一切喉风、单乳蛾、双乳蛾、重舌等病症，总离不开表、里、寒、热、虚、实六个字。医者临证如果能通权达变，彼此类推，就没有治不好的喉部疾病了。
第九条：本书毫无保留地全盘托出，不隐藏一方，不杜撰一法。医者得到它，可以立即治愈顽固疾病；患者研读它，也不会最终被庸医误导。救人的功劳，我不敢独占；害人的罪责，我将独自承担。
My maternal grandfather, Mr. Yin Shenwei, was erudite and skilled in poetry, calligraphy, and painting, each reaching its perfection. He was particularly proficient in Traditional Chinese Medicine (TCM). I studied under him, bearing my books on a shoulder pole, and devoted myself to the intensive study of Internal Medicine (Neike), External Medicine (Waike), Throat Diseases (Houke), and swelling conditions (Zhongzheng). Over twenty years, I experienced one by one all kinds of dangerous and adverse syndromes. Through extensive inquiry and consultation, and careful discussion, I privately felt that I had gained profound insights. However, for the disease of Diphtheria (Baihou), there were no specialized books in the world. Physicians specializing in throat diseases at that time neglected the theories in the *Huangdi Neijing* (Yellow Emperor's Inner Canon). Consequently, when encountering critical situations, they were often bewildered and unable to understand. Even a few eminent physicians were mostly constrained by conventional views; some leaned towards Cold patterns, others towards Heat patterns. Bias towards either Cold or Heat not only failed to serve as a resource for saving lives but became a weapon for killing. I pitied this deeply. In my spare time from reading, together with my cousin Zhao Zhongbiao, I compiled the *Baihou Quansheng Ji* (Complete Life Collection for Diphtheria) using the empirically effective prescriptions for treating Diphtheria passed down by my grandfather. This book takes "Cold" and "Heat" as its guidelines, further dividing them into mild, severe, deficiency, and excess within these categories. Its syndrome differentiation and pulse diagnosis are clearly categorized and meticulously analyzed, while the use of herbs and formulas allows for flexibility and adaptation. It is concise yet precise, simple yet comprehensive, enabling anyone who obtains this book to resolve doubts and difficulties. I dare not claim it as a miraculous prescription to save the world, but it is sufficient to revive critically ill patients.
Preface written in the winter month of Renwu year, 8th year of Guangxu reign, by Li Jifang, courtesy name Lunqing, from Hengshan, at Longmen Study.
Item 1: The Heat patterns of Diphtheria are originally more common, while Cold patterns are fewer. However, whether caused by Cold or Heat stagnation, toxicity is invariably present. This is why contemporary physicians specifically identify it as an Epidemic Toxin (Yi Du) and tend to prescribe cooling medications. They fail to realize that although Cold patterns of Diphtheria are rare, they do exist; just as Heat patterns have toxicity, Cold patterns are also not devoid of it. This one-sided view of contemporary physicians has killed countless people. The text sets up Q&A sections to distinguish points in detail; careful study will naturally reveal their errors.
Item 2: All diseases must involve either Cold or Heat natures; Diphtheria is no exception. This book uses "Cold" and "Heat" as the guideline, further distinguishing between mild, severe, deficiency, and excess, without any bias. The prescriptions are all derived from personal clinical experience, so the explanations are most pragmatic and pertinent.
Item 3: To distinguish between Cold and Heat, one must first confirm the symptoms. Once the symptoms are clearly identified, referring to the pulse reveals the true nature of the disease without concealment. Discussing the pulse can sometimes be vague, but discussing symptoms cannot be compromised. The ancients placed palpation (Qie) after observation (Wang), auscultation/olfaction (Wen), and inquiry (Wen), which holds deep meaning. Therefore, this book details syndrome differentiation extensively but simplifies pulse differentiation.
Item 4: This book divides diseases into three main categories: Cold Syndrome, Heat Syndrome, and Mixed Cold-Heat Syndrome. Regardless of how complex the condition changes, it always falls within these three categories. The formulas for these three syndromes are attached afterwards for easy reference.
Item 5: All formulas are modified from ancient established prescriptions; none are based on subjective speculation. By matching the formula to the syndrome, the medicine cures the disease effectively. Do not arbitrarily add or subtract ingredients. If there are concurrent syndromes, flexibility is allowed. The Mixed Cold-Heat Syndrome is particularly difficult to treat, hence the detailed discussion of its formulas.
Item 6: The method for treating Diphtheria requires caution in oral medication and precision in throat insufflation (Chuiyao). In remote rural areas where liquid medicine cannot be obtained immediately, throat insufflation relies entirely on emergency rescue. Contemporary physicians' common insufflation powders may suffice for mild cases but delay treatment in severe cases. The insufflation powders in this book are also divided into three main categories based on Cold, Heat, and Mixed Cold-Heat Syndromes. Medication according to the syndrome yields immediate results. One must not arbitrarily modify them.
Item 7: For critical and deteriorating cases of Diphtheria, characterized by trismus (lockjaw) and surging phlegm-saliva, where oral medication and insufflation are impossible, the method should first open the orifices to clear phlegm-saliva. In severe cases, acupuncture at various acupoints should be used to release evil blood, unblocking meridians and activating collaterals, leading to immediate consciousness. Then, insufflation and oral medication can cure the disease. The methods for opening orifices, applying plasters, and acupuncture in this book are extremely detailed; simply follow the prescribed methods.
Item 8: Although this book is specifically legislated for Diphtheria, all throat conditions such as Wind-Throat (Houfeng), single tonsillitis (Dan Shuang Rumei), double tonsillitis (Shuang Rumei), and double tongue (Chongshe) ultimately revolve around the six characters: Exterior, Interior, Cold, Heat, Deficiency, and Excess. If physicians can adapt flexibly during clinical practice and apply mutual analogy, there are no throat diseases that cannot be treated.
Item 9: This book discloses everything openly, hiding no single prescription nor fabricating any method. Physicians who obtain it can immediately cure chronic stubborn diseases; patients who read it will not ultimately be misled by incompetent doctors. I dare not take credit for the merit of saving lives, but I alone accept the blame for any harm caused.
