是集，乃平日阅书，随时札记，岁久成帙，重加删订而编次焉。首溯源二卷；次伤寒二卷；次杂证八卷；次
女科一卷、幼科一卷、痘疹一卷、方药一卷。共十六卷。书分数种，门类各殊，体裁不能画一，观者谅之！
所述经语，谨载诸书之前，以示尊经之意。所述先哲格言，其间序次，则或以意义之相承，或以病候之递及，
不以年代为先后。惟杂证各门哲言补编，首列仲景之言者，以仲景为医圣也。
所辑近代诸书，或议论纯粹，或治法精良，或譬喻明切，或辨驳条畅。稍涉肤庸，概从割爱。
所辑群言，只期切要。故或节录数行，或采摘数语，或摭拾数字，无非删繁就简之意耳。
所辑各家之书，其书目姓名，即载明条下。然间有一人前后书目姓名互见者，有单着书目或单着姓名者，亦
有书目姓名并失记者。博雅君子，自能识之。
妇人、小儿两科，因有经带胎、产、惊、疳、痘、疹等候，故较诸男子延医倍难。历考古今方书，惟薛立斋医
案、王损庵《绳准》尤为详细。无如卷帙繁衍，阅之不易。是集仅挈大纲，欲窥全体，考核两家之书自悉。
各家医书，凡伤寒、杂证所用成方，每汇篇末，以备考核。然古方甚繁，大概已见《医方考》、《名医方论》、
《医方集解》等书，是集另辑方论一册，撮其大略，或有匠心独创与得自传闻，法属精良者，间于各门附载一、
二。惟幼科丸、散诸方，
所载较多，备急用也。至于痘疹方法，因本卷书帙已盈，未能载及，专科诸书具在，自可检阅。
本草，名家着述∶博者，莫如时珍《纲目》，约者，莫如 庵《备要》。是集所辑《药略》一册，不无太简，
实缘限于尺幅，故仅揭其要耳。
医之有案，如弈之有谱也。然一家案中求其精粹者，亦不多得。即名医类案一书，非不悉备，窃恐广罗寡要，
是集所载，务求超群迈众，阅之令人心思开扩。泛常诸案，悉不纂入。
经、史、子、集诸书，有与医术相通者，间述一、二。非故繁称博引，诚以此事系生死所关，古圣贤亦尝留意。
不当以小道外之也。
《张氏医通》、《证治汇补》、《沈氏尊生》诸书，亦皆遴选诸家名论，然每参以己意。是集专述古人之言，
毫不敢窃附鄙见者，盖恐蹈妄作之愆也。
这部书，是我平日阅读医书时随手做的笔记，经过多年积累成册后，重新加以删减修订并编排次序而成。首先追溯源流两卷；其次是伤寒论两卷；接着是杂病八卷；然后是妇科一卷、儿科一卷、痘疹科一卷、方药一卷。共计十六卷。书中分为多种类别，门类各不相同，体例无法完全统一，希望读者谅解！
对于经典著作中的语句，我恭敬地记载在相关章节的前面，以表示尊重经典的用意。对于先贤哲人的格言，其中的排列顺序，有的是依据意义的承接关系，有的是依据病症的递进关系，并不按照年代先后排序。只有在杂病各门补充编录的哲言中，首先列出张仲景言论的，是因为张仲景被尊为“医圣”。
所辑录的近代书籍，有的议论纯粹精当，有的治疗方法精良，有的比喻明白透彻，有的辨析驳斥条理清晰。稍微涉及肤浅平庸的内容，一概舍弃不取。
所辑录的各种言论，只追求切合要害。因此有时节录几行文字，有时摘取几句话，有时仅拾取几个字，无非是为了删去繁杂、保留精简的意思罢了。
所辑录的各名家书籍，其书名和作者姓名，都明确记载在相应条目之下。然而偶尔会出现同一人前后书目或姓名重复出现的情况，也有只记载书名或只记载姓名的情况，甚至还有书名和姓名都遗漏未记的。博学雅正之士，自然能够识别。
妇科和儿科这两个科目，因为涉及经血、带下、妊娠、分娩、惊风、疳积、痘疮、麻疹等病情，所以比男子看病要困难得多。考证古今方书，只有薛立斋的医案和王损庵的《绳准》尤为详细。无奈篇幅繁多，阅读起来不容易。这本书仅提取大纲要点，想要窥探全貌，考核这两家的原著自然就能知晓。
各家医书中，凡是治疗伤寒、杂病所用的成方，每篇末尾都会汇总，以备考核参考。然而古方非常繁多，大体内容已经见于《医方考》、《名医方论》、《医方集解》等书中。本书另外辑录方论一册，概括其大略，如果有独具匠心独创或与传闻所得且方法精良的方剂，偶尔在各门中附载一两首。至于儿科用的丸剂、散剂等方子，所载较多，以备紧急使用。至于痘疹的治疗方法，因为本卷篇幅已满，未能收录，专科书籍都在，自然可以查阅。
关于本草学，名家的著作：广博的，没有超过李时珍的《本草纲目》；简约的，没有超过（缪希）雍的《本草备要》。本书所辑录的《药略》一册，不免过于简略，实在是受限于篇幅，所以仅揭示其要点罢了。
医生的医案，就像棋谱一样。然而在一家医案中寻求精粹之作，也不多见。即使是《名医类案》一书，并非不齐全，但我担心其广博而缺乏要点。本书所载，务必追求超越众人，让读者读后心思开阔。平常一般的医案，全部不予收录。
经、史、子、集各类书籍中，有与医术相通的，偶尔叙述一两条。并非故意繁复地称引博采，确实是因为医学关系到生死存亡，古代圣贤也曾留意于此。不应将其视为小道而轻视它。
《张氏医通》、《证治汇补》、《沈氏尊生》等书，也都是遴选各家名言警句，但往往夹杂个人的见解。本书专门阐述古人的言论，丝毫不敢窃取附上自己的浅见，大概是害怕犯下妄自创作的过错啊。
This work consists of notes taken at various times during my daily reading of medical books, which accumulated over the years into a manuscript. It has since been re-edited, revised, and arranged in order. The first section traces the origins in two volumes; followed by Treatise on Cold Damage (Shanghan) in two volumes; then Miscellaneous Diseases (Zazheng) in eight volumes; followed by Gynecology (Nüke) in one volume, Pediatrics (Youke) in one volume, Smallpox and Measles (Douzhen) in one volume, and Formulas and Medicinals (Fangyao) in one volume. In total, there are sixteen volumes. Since the book is divided into various categories with distinct classifications, the format cannot be uniform; I hope readers will understand this.
Regarding quotations from classical texts, they are respectfully recorded at the beginning of the relevant sections to demonstrate reverence for the classics. For maxims and aphorisms of ancient sages, the arrangement follows either the continuity of meaning or the progression of symptoms, rather than chronological order. However, in the supplementary compilation of sage quotes under each category of miscellaneous diseases, the words of Zhang Zhongjing are listed first because he is revered as the Sage of Medicine (Yi Sheng).
The modern works compiled herein include those with pure and refined discussions, excellent treatment methods, clear and apt analogies, or well-structured refutations. Any content that is superficial or mediocre has been discarded.
The collected statements aim only for relevance and conciseness. Therefore, sometimes only a few lines are excerpted, sometimes a few sentences are picked out, or merely a few characters are gathered; all serve the purpose of removing complexity and retaining simplicity.
For the various masters' works cited, the book titles and authors' names are clearly stated under each item. Occasionally, the same author's name or book title may appear multiple times throughout the text; sometimes only the book title or only the name is recorded; and in some cases, both are omitted. Learned scholars will naturally be able to identify these.
Gynecology and pediatrics involve conditions such as menstrual disorders, leukorrhea, pregnancy, childbirth, convulsions, infant malnutrition (Gan syndrome), smallpox, and measles. Consequently, treating women and children is significantly more difficult than treating men. Examining ancient and modern medical texts, only the medical cases of Xue Lizhai and Wang Sun'an's *Shengzhun* are particularly detailed. However, due to their extensive length, they are not easy to read. This book extracts only the main outlines; for a comprehensive understanding, one should refer to the original works of these two masters.
Completed formulas used for treating cold damage and miscellaneous diseases from various medical texts are summarized at the end of each chapter for reference. Ancient formulas are numerous, and their general content can already be found in books such as *Yifang Kao*, *Mingyi Fanglun*, and *Yifang Jijie*. This book compiles an additional volume of formula theories, summarizing the essentials. Formulas demonstrating unique ingenuity or derived from reliable reports with excellent therapeutic effects are occasionally appended to relevant chapters. Formulas for pediatric pills and powders are included in greater numbers to prepare for emergencies. Regarding treatments for smallpox and measles, space in this volume was insufficient, so they were not included; specialized texts are available for consultation.
Regarding materia medica, among famous scholarly works: the most comprehensive is Li Shizhen's *Bencao Gangmu*; the most concise is [Miao] Yi's *Bencao Beiyao*. The *Yaolue* (Brief Outline of Medicinals) compiled in this book is admittedly too brief, constrained by limited space, thus covering only the essentials.
Medical cases are like chess manuals. However, finding exquisite examples within a single practitioner's collection is rare. Even the *Mingyi Leian* (Collected Cases of Famous Physicians) is not incomplete, but it may be too broad and lack focus. The cases selected here strive to surpass the ordinary, aiming to broaden the reader's perspective. Ordinary cases are excluded.
Works from the Classics, Histories, Philosophers, and Collections that intersect with medicine are occasionally cited. This is not done to display erudition, but because medicine concerns life and death, a matter attended to even by ancient sages. It should not be dismissed as a trivial pursuit.
Books such as *Zhangshi Yitong*, *Zhengzhi Huibu*, and *Shenshi Zunsheng* also select famous theories from various sources but often interweave personal opinions. This book exclusively presents the words of ancients, daring not to insert my own humble views, lest I incur the fault of presumptuous fabrication.
