一此书专以六气四因为主。盖风寒暑湿燥火自外而致。气血痰郁自内而生。虽曰变幻多端。
大要皆不越此。
一治病。必以脉为先。脉不明。则无由识症。而阴阳寒热。亦无从辨。故引用脉义。专以崔
真人脉诀为主。而以王叔和脉经参之。其有未备者。则 附己意。一脉明。而后审症。症不

家之说。而直称某书云。或某云。使阅者知有根据。
一症明。而后论治。治法不明。则用药无所据。故治法亦以内经。四子为主然后参以诸家之
说。有合经意者。则录之。未备者。则 附已意以补之。其余概不敢泛录。恐雅郑之混也。

春严吴正伦议。
一、本书专门以六气和四因为主要依据。风寒暑湿燥火是从外部侵袭人体所致，气血痰郁是从内部产生。虽然病情变化多端，但大要都不超出这些范畴。
一、治病必须以脉诊为先。脉象不明，就无法识别症状，阴阳寒热也无从辨别。因此引用脉学理论，专门以崔真人《脉诀》为主，并参考王叔和的《脉经》。其中有所欠缺的地方，则附上自己的见解。一旦脉象明了，然后审察症状；症状不审察清楚，就无法实施治疗。因此论述症状专门以内经为主，其次以刘完素、张元素、李东垣、朱丹溪四家的议论作为辅助。如果有未完备之处，则参考其他各家的说法，直接称“某书说”或“某人云”，使阅读者知道有根据。
一、症状明确后，然后论述治疗。治疗方法不明确，用药就无所依据。因此治疗方法也以内经和四子（指刘、张、李、朱）为主，然后参考其他各家的说法。符合经义的就记录下来，不完备的地方，就附上自己的见解来补充。其余一概不敢随意收录，恐怕混淆雅正与淫邪之音。
一、治疗方法明确后，然后制定方剂。方剂不当，就不能治愈疾病。因此立方的专门选取古代名方一二道作为主体，顺应四季变化的症状，随症加减，这样或许就不会有拘泥固执的讥讽了。
一、按脉诊察，审察症状，因症状斟酌治法，因治法确定方剂，这四者是相承相继的。确实在这四个方面没有错误，那么医理就没有遗漏了。书中分门别类，已经条理井然，而在每个门类中，又依次编辑。首先论脉，其次论症，再次论治，最后论方，使读者一目了然。所以就用这个名称命名本书，希望阅读者能因名而知义。
一、在症治部分，或者适宜使用其他方剂，全部探求附录在卷末，以便查阅。
一、妇女儿童的各类病症，虽然有胎产、血气、惊疳、变蒸、痘疹的不同，但也不外乎六气和四因。然而与男子相同的病症，治疗方法也相同。其余症状也各自附在篇内，这里不再详细涉及。
一、药方，全部按照现在的分量，以一帖为标准格式，以便于使用。
一、编纂撰写这本书，非常便于初学者学习，所谓下学之事。而上达的功夫，也不过如此。
然而人命关天，怎么敢自信议论已经精当，采集摘录完全恰当。如果设有瑕疵疏漏，希望高明的人士，幸而予以纠正。
春季严冬之际，吴正伦评议。
1. This book focuses primarily on the Six Qi (Six climatic factors: Wind, Cold, Summer-heat, Dampness, Dryness, Fire) and the Four Causes (Four internal pathogenic factors: Emotions, Diet, Trauma, Parasites). Wind, Cold, Summer-heat, Dampness, Dryness, and Fire are caused by external invasion, while Qi stagnation, Blood stasis, Phlegm, and Depression arise from within. Although clinical manifestations are diverse and changing, the general principles do not exceed these categories.
2. In treating disease, pulse diagnosis must come first. If the pulse is not understood, symptoms cannot be identified, and Yin-Yang and Cold-Heat patterns cannot be distinguished. Therefore, in citing pulse theory, this work relies primarily on Cui Zhenren's *Mai Jue* (Pulse Mantra), supplemented by Wang Shuhe's *Mai Jing* (Pulse Classic). Where these sources are incomplete, personal insights are added. Once the pulse is clarified, symptoms are then examined; if symptoms are not carefully assessed, treatment cannot be applied. Thus, the discussion of symptoms relies primarily on the *Nei Jing* (Inner Canon), with the theories of Liu Wansu, Zhang Yuansu, Li Dongyuan, and Zhu Danxi serving as supplementary support. Where these are insufficient, references to other schools are included, explicitly cited as "According to [Book Name]" or "[Person] says," so that readers know the basis.
3. Once symptoms are clear, treatment methods are discussed. If treatment methods are unclear, there is no basis for prescribing herbs. Therefore, treatment methods also prioritize the *Nei Jing* and the four masters (Liu, Zhang, Li, Zhu), supplemented by other scholarly views. Those consistent with canonical principles are recorded; where they are incomplete, personal insights are added to supplement them. Other materials are generally not included to avoid confusing orthodox teachings with heterodox ones.
4. Once treatment methods are clear, formulas are formulated. If a formula is inappropriate, the disease cannot be cured. Therefore, this work primarily selects one or two ancient famous formulas as the foundation, adapting them according to seasonal variations and specific symptoms through modification. This approach helps avoid the criticism of rigid adherence to fixed prescriptions.
5. Pulse diagnosis, symptom assessment, treatment selection based on symptoms, and formula determination based on treatment are four interconnected steps. If these four aspects are free from error, medical reasoning will be complete. The book is categorized into sections with clear organization. Within each section, content is arranged sequentially: first discussing pulse, then symptoms, then treatment, and finally formulas, allowing readers to grasp the content at a glance. Hence, the book is named accordingly, enabling readers to understand its meaning through its title.
6. In the sections on symptoms and treatment, if alternative formulas are appropriate, they are explored and appended to the end of the volume for easy reference.
7. Various conditions in women and children, despite differences such as pregnancy/childbirth, blood disorders, fright, malnutrition (Gan syndrome), developmental changes (Bianzheng), and smallpox/rash diseases, still fall under the framework of the Six Qi and Four Causes. However, conditions identical to those in men are treated with the same methods. Other related conditions are attached to the respective chapters, but are not detailed here.
8. Herbal prescriptions follow current weight measurements, standardized per single decoction dose, for practical convenience.
9. Compiling this book greatly facilitates learning for beginners, representing the "lower learning" stage. Yet, the attainment of "higher understanding" does not lie beyond this scope.
However, human life is precious. How dare I claim my discussions are precise and my citations entirely accurate? Should any flaws or omissions exist, I hope scholars of high caliber will kindly point them out.
