新安程子杏轩，深于医，着有《医案》一书，发明其理甚悉。予因思医书，惟《灵枢》
、《
素问》最古，虽未敢必为神农氏以后之书，然其为战国时神于是术者之所为无疑也。由是推
之，《春秋》左氏传医和医缓诸论说，更推之周官医师食医疡医诸职守，所云阴阳风雨晦明
之
生疾，九窍九脏之变动，辞约义备，医之理尽矣。后世着书者，代作短长，往往互见，程子
去其短集其长，盖尤有心得。《医案》一书，谓与《灵枢》、《素问》并传可也。

新安人程杏轩，对医学造诣深厚，撰写了《医案》一书，对其中的医理阐述得非常详尽。我因此想到，医书中以《灵枢》和《素问》最为古老，虽然不敢断定它们一定是神农氏之后的著作，但毫无疑问它们是战国时期精通医术的人所写的。由此推论，《春秋左氏传》中关于医和、医缓等人的论述，再追溯到《周礼》中医师、食医、疡医等职官的职责，其中所说的阴阳风雨晦明导致疾病，九窍九脏的变化，言辞简练而义理完备，医理至此可谓穷尽。后世著书立说的人，各有所长短，往往内容重复交叉，程先生去其短处，集其长处，更有独到的心得。《医案》这本书，可以说可以与《灵枢》、《素问》并列流传。

程杏轩（名埃绵，字藐）感叹岐黄之风寥落，《素问》、《灵枢》这类书籍显得遥远难及。程杏轩先生悟性极高，超越世俗，思考精密，超过常人，既拥有潘岳、陆机般的诗名，又精通俞跗、扁鹊那样的医术。他平生治病，多有奇效，有的通过叩击背部引出瘀血，有的用冷水浇头来急救，他在当地名声远扬，美誉传遍千里。我曾遭遇危重病症，依靠他才得以保全性命，因此我们结下了如兰金般坚固的情谊，我对他的感激之情深入骨髓。闲暇时登门拜访，他向我展示了他编著的医案。阅读这些医案，提纲挈领如同掌握元珠，探究深奥之处如同纪昌射箭穿透虱子中心。使死者复生、朽木逢春的本事不止一端，观察面色、审视毫毛，殊异的功绩屡有奏效。即使是葛洪的金匮之作，孙思邈龙宫之秘，隐居本草的记录，宣公集验的书籍，与这本医案相比都显得逊色。心中充满佩服，退而写下序言，这确实足以拯救膏肓之疾，请将其刻印出版。

子华子曾说：“医生，讲的是理，用的是意。”大概道理明白了，意就能得到；意得到了，在诊脉处方时，就没有不准确的。这样称他为国家级名医并不困难，我的同宗杏轩先生就是这样的人。先生天性聪颖，擅长诗歌，以行医为隐逸之道，为人治病，手到病除，立即见效。我的同年好友鲍觉生，曾经遭遇危重疾病，依靠先生才得以康复，他的母亲口中不断称赞。有一天，先生拿出他所著的医案，嘱托我为其作序，我接受并阅读，发现他诊脉处方，深得古人“四然二反”的道理，并且神妙地运用其意，因此赞叹先生的技艺精湛，不是那些寻常拿着经方、练习针石的人所能望其项背的。那么这本书，大概是桐君（黄帝臣子，医药始祖之一）的别录，越人（扁鹊）的逸篇吧。
嘉庆十年岁在构蒙赤奋若余月 鹤樵国仁拜书
Cheng Xuan of Xin'an was deeply versed in medicine and authored the *Medical Cases* (*Yi An*), elucidating medical principles with great detail. This led me to reflect that among medical texts, the *Ling Shu* (Spiritual Pivot) and *Su Wen* (Basic Questions) are the most ancient. Although I dare not assert definitively that they were written after the time of Shennong, it is beyond doubt that they were composed by those proficient in these arts during the Warring States period. From this, we can infer that the discussions on medicine by Yi He and Yi Huan in the *Zuo Zhuan* commentary on the *Spring and Autumn Annals*, and further back to the duties of physicians, dietitians, and surgeons recorded in the *Rites of Zhou*, where it speaks of diseases arising from yin, yang, wind, rain, darkness, and brightness, and changes in the nine orifices and nine viscera, all use concise language yet cover comprehensive meanings, exhausting the principles of medicine. Later authors have produced works of varying quality, often overlapping in content. Mr. Cheng removed the shortcomings and collected the strengths, demonstrating particularly insightful understanding. The book *Medical Cases* can be said to be worthy of transmission alongside the *Ling Shu* and *Su Wen*.

Cheng Xuan (courtesy name Aimian, pseudonym Miao) lamented the scarcity of the Qi-Huang tradition. Books like the *Su Wen* and *Ling Shu* seem distant and remote. Mr. Cheng Xuan possessed extraordinary insight surpassing the world, and profound thought exceeding ordinary people. He excelled in poetry like Pan Yue and Lu Ji, and mastered the healing arts of Yu Fu and Bian Que. Throughout his life, his treatments for illnesses often yielded miraculous effects; some involved striking the back to expel blood, others using water poured on the head for emergency rescue. His reputation spread across a thousand li within his region. I once suffered from a critical condition and relied on him to survive; thus, our friendship became as solid as orchids and gold, and my gratitude runs deep into flesh and bone. On leisure days, I visited him, and he showed me his compiled medical cases. Reviewing them, extracting the essentials was like grasping the pearl of wisdom; delving into the obscure was like Ji Chang threading an arrow through a louse. His ability to revive the dead and rejuvenate the decayed was manifold. Observing complexion and examining fine hairs, his exceptional achievements were repeatedly demonstrated. Even the works of Ge Hong's Golden Cabinet, the secrets of Sun Simiao's Dragon Palace, the records of the Hermit's Materia Medica, and the collected verified cases of Xuan Gong, pale in comparison to this work. Overwhelmed with admiration, I withdrew to write this preface. It is indeed capable of saving those with terminal ailments; please have it engraved and published.

Zi Hua Zi said: "Medicine is about principle (*Li*) and intuition/mind-intent (*Yi*)." When principles are clear, intent is attained; when intent is attained, pulse diagnosis and prescription formulation will hit the mark without fail. In this way, calling someone a national master physician is not difficult; my clansman, Mr. Xuanxuan, is such a person. The Master was naturally intelligent, skilled in poetry, and practiced medicine as a form of reclusion. When treating patients, he achieved immediate results upon applying his hands. My contemporary friend Bao Juesheng once suffered from a critical illness and was revived thanks to the Master; his mother praised him incessantly. One day, the Master presented his written medical cases and requested a preface from me. Upon receiving and reading them, I saw that his pulse diagnosis and prescription formulation deeply understood the ancient principles of "Four Confirmations and Two Reversals" (*Si Ran Er Fan*), and he divinely applied his intent. Therefore, I marveled at the precision of his art, which far surpassed what ordinary practitioners holding canonical formulas and practicing acupuncture could hope to match. Thus, this book may well be considered an alternate record of Tong Jun (a mythical figure associated with the origins of Chinese medicine) or a lost chapter of Yue Ren (Bian Que).
