夫医者，人之司命也；脉者，医之大业也。盖医家苟不明脉，则如冥行索途，动致颠复
夫大方脉、妇人、小儿、风科，必先诊脉，后对症处药。独疮科之流，多有不诊其脉候，专
攻治外；或有证候疑难，别召方脉诊察，于疮科之辈，甘当浅陋之名。噫！其小哉如是。原
夫疮肿之生，皆由阴阳不和，气血凝滞。若不诊候，何以知阴阳勇怯，气血聚散也。由是观
之，则须信疗疮肿于诊候之道，不可阙也。历观古今，治疗疮肿方书甚多，其间诊候之法，
略而未详，比夫诸科，甚有灭裂。愚虽不才，辄取《黄帝素问》、《难经》、《灵枢》、《甲乙》及
叔和、仲景、扁鹊、华佗、《千金》、《外台》、《圣惠》、《总录》，古今名医诸家方论之中，诊
候疮肿之说，简编类次，贯成篇帙。首载诊候入式之法，次论血气色脉参应之源，后明脉之
名状、所主证候及疮肿逆从之方，庶使为疮肿科者，览此则判然可晓，了
朝临疾，诊候至此，则察逆从，决成败，若黑白之易分耳！
夫天地之道，曰阴与阳；阴阳在人，曰血与气。盖血者荣也，气者卫也；荣者荣于中，
卫于外。所以荣行脉中，卫行脉外；脉者，血气之先也。血非脉则焉能荣于中？气非脉则焉
能卫于外？二者相资而行，内则通于五脏六腑、十二经络；外则濡于九窍四肢、百节万毛。
昼夜循行，如环无端，以成其度。会于寸口，变见于脉。故曰气血者，人之神也；脉者，气
血之神也。所以治病之始，五决为纪。盖五决者，五脏
色之与脉，当相参应。故曰能合色脉，可以万全也。凡
此不精，虽聪惠辩博，亦不足委也。
The physician is the one who holds the life and death of human beings; pulse diagnosis is the greatest undertaking in medicine. If a physician does not understand the pulse, it is like groping for a path in the dark, inevitably leading to stumbling and falling.
For internal medicine (Da Fang Mai), gynecology, pediatrics, and wind disease departments, one must first diagnose the pulse before prescribing medication according to symptoms. Only in the department of sores and ulcers do many practitioners fail to examine the pulse, focusing exclusively on external treatments; or when encountering difficult cases, they summon internal medicine specialists for consultation, thereby accepting the reputation of being shallow and ignorant. Alas! How limited their perspective is.
Investigating the origin, the emergence of sores and swellings is all due to the disharmony of Yin and Yang, and the stagnation of Qi and Blood. Without pulse diagnosis, how can one know the strength or weakness of Yin and Yang, and the gathering or dispersal of Qi and Blood? From this, it is clear that in treating sores and swellings, the method of pulse diagnosis cannot be omitted. Reviewing ancient and modern times, there are many medical texts on treating sores and swellings, yet the methods of pulse diagnosis within them are often brief and undetailed, appearing very negligent compared to other specialties. Although I am untalented, I have selected discussions on diagnosing sores and swellings from the prescriptions and theories of famous physicians past and present, including *Huangdi Suwen* (Yellow Emperor's Inner Canon: Basic Questions), *Nanjing* (Classic of Difficult Issues), *Ling Shu* (Spiritual Pivot), *Jia Yi Jing* (A-Behavior Classic), as well as those by Wang Shuhe, Zhang Zhongjing, Bian Que, Hua Tuo, *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold), *Waitai Miyao* (Secret Essentials of the Outer Terrace), *Taiping Shenghui Fang* (Holy Grace Formulas of the Taiping Era), and *Tai Ping Hui Min He Ji Ju Fang* (Formulas of the Taiping People's Welfare Bureau). I have compiled and arranged these excerpts into chapters. First, I record the standard methods of pulse diagnosis; second, I discuss the principles of correlating blood, Qi, complexion, and pulse; finally, I clarify the names and appearances of pulses, the syndromes they govern, and the methods for determining favorable and unfavorable outcomes in sores and swellings. It is hoped that practitioners in the field of sores and swellings, upon reading this, will find it clearly understandable. When facing diseases at dawn, having reached this level of diagnosis, distinguishing between favorable and unfavorable outcomes, and deciding success or failure, will be as easy as distinguishing black from white!
The way of Heaven and Earth lies in Yin and Yang; within humans, Yin and Yang manifest as Blood and Qi. Generally speaking, Blood is Ying (Nutritive) Qi, and Qi is Wei (Defensive) Qi; Ying nourishes internally, while Wei protects externally. Therefore, Ying circulates within the vessels, and Wei circulates outside the vessels; the vessels are the pioneers of Blood and Qi. Without vessels, how can Blood nourish internally? Without vessels, how can Wei protect externally? These two rely on each other to circulate, connecting internally with the Five Zang and Six Fu organs and the Twelve Meridians; externally moistening the Nine Orifices, four limbs, joints, and hairs. They circulate day and night like a circle without beginning or end, establishing their proper rhythm. They converge at the Cun Kou (Radial Artery Pulse Point) and manifest changes in the pulse. Thus it is said: Blood and Qi are the spirit of humanity; the pulse is the spirit of Blood and Qi. Therefore, the beginning of treatment takes the Five Determinations (Wu Jue) as its guideline. The so-called Five Determinations refer to the Five Zang organs.
Complexion and pulse should correspond with each other. Thus it is said: One who can combine the analysis of complexion and pulse can achieve perfection in ten thousand cases. If one is not proficient in these aspects, even if intelligent, wise, eloquent, and knowledgeable, one is not worthy of trust.
