医镜者，小子元宰嗣父松园公竭三十余年探索之功，揣摹按验，审时用药，察症定方，恍乎有得，
再四删削，务期醇正，不尚奇僻之见，以致学医人费之诮。我嗣父之成书，其用心有如此者。嗣父同
气二人，小子宰、乃仲氏，西侯公所出，年甫十龄，嗣父艰于得子，又蒙重疾，根据次房嗣宰为子，蒙恩
抚育，延师授室，无异所生。吾父壮年名噪黉序，两预棘闱。后因疾作，延医诊视，百无一效，逐废
举子业，穷究医药之理，远达京邸，与试国学，就职医院，因而考订岐黄、灵素诸书者有年，又于辇下
诸名家，讲求精理，始旷然有见。医家寄人生死，时下用药多误，诊脉不审，往往杀人。大抵胸无定
见，多为成方所拘。如新室之袭尚书，金陵之泥周礼，偏见曲学，祸国祸民，医道亦然。古人云∶上医医国，
次则医人。要之出死入生，挽回性命，其功不减于医国。此我父所为攻苦二十年，寒檠雪案，手不停披，
辄命小子宰昼夜钞辑，垂成辄复改窜，凡数十次。此种苦心，惟小子宰亲见而熟悉之。时嗣姊丈简中，壬
午科，今授山东守府，字亦可者，与小子宰同受恩于松园翁，素佩服吾父之书，有功后世，同为参证。我
两人窃相拟议，今之号为明医，大抵云积阴功居半，养身家居半。夫一心两用，其于医道，岂尽当乎。况
彼所云阴功者，又未尝力学好古，从勤苦中得来也。小子宰谬列武庠，未免分功内外场事，不及授吾父伐毛
洗髓之秘，然吾父生平辛勤，惟思救人济世，力挽庸医僻见，若绝不作身
家计者，小子亦得于历年钞撮之余，深悉其用心之专且至也。亦可程公向服膺此书，数寓书于宰促其录

时康熙五十八年，腊月朔旦。
生甘菊（连根捣碎，用量一至二两）、金银花（五至六钱）、紫花地丁、生地、茜草、甘草节（各三至五钱）、连翘、牛蒡子、贝母、天花粉（各二至三钱）、白芨、白芷（各一至二钱）、夏枯草（五至六钱），煎汤作为药引。如皂角刺、穿山甲、鲜首乌、赤芍、牛膝、地榆、犀角之类，都可以采用。溃破后加黄芪（用盐水炒制）、薏苡仁（五钱至一两）、山药、白芍（各三至五钱）、麦冬（五至六钱）、五味子（约一钱）。体虚者加人参（五钱至三两）。
此方具有凉血散瘀、清热解毒、散结消肿的功效。我曾使用此方加减，治疗一切外科大小病症，未溃破的能消散，已溃破的能收敛，大剂量使用见效快，小剂量使用见效慢但稳妥。
《医镜》这本书，是我元宰继承父亲松园公耗费三十多年探索之功，揣摩模仿并经过临床验证，审察时令用药，观察症状定方，仿佛有所心得，经过反复删减修改，务必追求纯正，不崇尚奇特偏颇的见解，以免让学医的人受到讥笑。我继父编写成书，其用心就是这样。继父有两位同父异母的兄弟，我是长子，弟弟是次子，都是西侯公所出。继父十岁时，因难以得到子嗣，又遭遇重病，于是过继给次房为子，蒙受恩惠被抚养长大，聘请老师教导，娶妻成家，与亲生儿子无异。我的父亲壮年时在学堂中名声显赫，两次参加乡试。后来因病发作，延请医生诊治，百无一效，于是放弃科举事业，穷究医药的道理，远赴京城，参加国子监考试，任职于太医院，因此考证订正岐伯、黄帝内经等书籍已有多年，又在京城向各位名家请教，精研医理，才豁然开朗有所见解。医家寄托着病人的生死，当时用药多有误，诊脉不审慎，往往导致病人死亡。大概是因为心中没有定见，多被成方所拘束。就像新室之袭尚书，金陵之泥周礼，偏见曲学，祸国祸民，医道也是如此。古人说：上医治国家，其次治人。总之，使人起死回生，挽回性命，其功劳不亚于治国。这是我父亲所以刻苦钻研二十年，在寒灯雪案下，手不停翻书，总是命令我元宰昼夜抄录编辑，快要完成时又重新修改窜改，凡几十次。这种苦心，只有我元宰亲眼见到而熟悉它。当时继姐夫简中，壬午科进士，现在授予山东守府职位，字亦可，与我元宰一同蒙受松园翁的恩惠，一向佩服我父亲的书，对后世有功，共同参证。我们两人私下商议，现在的号称明医，大概积累阴功占一半，养身家居占一半。一心两用，对于医道，难道完全恰当吗？况且他们所说的阴功，又没有曾经努力学习好古，从勤苦中得来。我元宰谬列武庠，未免分心内外场事务，来不及传授我父亲伐毛洗髓的秘密，但我父亲生平辛勤，只想着救人济世，极力挽回庸医的偏颇见解，好像完全不考虑自身家庭利益，我也得以在历年抄录撮要之余，深深了解他用心的专一和极致。亦可程公向来信奉此书，多次写信给我催促其录成，邮寄到官署，以待当代知心好义之人，共同襄助刊刻，以此来救世，也就是活人，医国医人，都有赖于此。庶不负松园公对后学的正确方向，对先圣的继往开来，他的宏大志愿，庶得以借此抒发。我元宰手拙性鲁，不学无术，既不能开阐医道新学，又无法追述继父的遗志，即使是他热爱方术的特长，我元宰也不能叙述，谨拜而为之跋。
康熙五十八年腊月初一。
Raw Chrysanthemum Indicum (Gan Ju) [crushed with roots, 1-2 liang], Honeysuckle Flower (Jin Yin Hua) [5-6 qian], Violet Herb (Zi Hua Di Ding), Rehmannia Root (Sheng Di), Rubia Root (Qian Cao), Licorice Root Nodes (Gan Cao Jie) [each 3-5 qian], Forsythia Fruit (Lian Qiao), Burdock Fruit (Niu Bang Zi), Fritillaria Bulb (Bei Mu), Trichosanthes Root (Hua Fen) [each 2-3 qian], Bletilla Rhizome (Bai Ji), Angelica Dahurica (Bai Zhi) [each 1-2 qian], Prunella Spike (Xia Ku Cao) [5-6 qian]. Decoct in water to serve as a decoction base. Such herbs as Gleditsia Sinensis Spine (Zao Jiao Ci), Pangolin Scales (Chuan Shan Jia), Fresh Polygonum Multiflorum Root (Xian Shou Wu), Red Peony Root (Chi Shao), Achyranthes Root (Niu Xi), Sanguisorba Root (Di Yu), and Rhinoceros Horn (Xi Jiao) may also be adopted. After ulceration, add Astragalus Root (Huang Qi) [stir-fried with salt water], Coix Seed (Yi Yi Ren) [5 qian to 1 liang], Chinese Yam (Shan Yao), White Peony Root (Bai Shao) [each 3-5 qian], Ophiopogon Tuber (Mai Dong) [5-6 qian], Schisandra Berry (Wu Wei Zi) [approx. 1 qian]. For deficiency patterns, add Ginseng Root (Ren Shen) [5 qian to 3 liang].
This formula cools the blood and dissipates stasis, clears heat and detoxifies, scatters nodules and reduces swelling. I have used this formula with modifications to treat all external surgical conditions of various sizes. For those not yet ulcerated, it promotes resolution; for those already ulcerated, it promotes healing. Large doses yield rapid effects, while small doses yield gradual but steady effects.
"Yi Jing" (Medical Mirror) is a work compiled by my father, Mr. Song Yuan, after thirty years of exploration. He studied, imitated, verified through clinical practice, adjusted medications according to seasonal changes, and determined prescriptions based on symptom observation. Having gained insights, he repeatedly revised and deleted content, striving for purity and orthodoxy, avoiding eccentric or biased views that might invite ridicule from students of medicine. This reflects his dedication in completing the book. My father had two half-brothers; I am the eldest son, and my younger brother is the second son, both sons of Mr. Xi Hou. When my father was ten years old, due to difficulties in having offspring and suffering from severe illness, he was adopted into the secondary branch family. He was graciously raised, tutored, and married, treated no differently than a biological son. My grandfather was famous in the academic circles during his youth and participated in the provincial examinations twice. Later, due to illness, despite medical consultations, treatments were largely ineffective. Consequently, he abandoned the imperial examination path and devoted himself to studying the principles of medicine. He traveled to the capital, took the examination for the Imperial Academy, and served in the Imperial Hospital. Thus, he spent years collating and verifying texts such as the *Huangdi Neijing* (Yellow Emperor's Inner Canon). He also sought out renowned experts in the capital to refine his understanding of medical theory, achieving sudden clarity and insight. Physicians hold life and death in their hands. At that time, many medication errors occurred due to unexamined pulse diagnosis, often leading to death. Generally, this stemmed from a lack of independent judgment and being constrained by established formulas. Just as certain scholars blindly followed ancient texts like the *Shangshu* or *Rites of Zhou*, causing harm to the state and people, so too does rigid adherence to dogma harm patients in medicine. The ancients said: "The superior physician treats the state; the next level treats individuals." Ultimately, saving lives and restoring health is a merit comparable to governing a nation. This motivated my father to study hard for twenty years, working day and night under cold lamps and snowy desks, constantly reading. He always ordered me, Yuan Zai, to copy and compile these notes day and night. As the manuscript neared completion, he would revise it again, doing so dozens of times. Only I, Yuan Zai, witnessed and understood this painstaking effort.
At that time, my step-sister's husband, Jian Zhong, passed the Renwu examination and was appointed as the Prefect of Shandong. His courtesy name was Yike. He and I shared gratitude towards Mr. Song Yuan. He deeply admired my father's book, recognizing its benefit to future generations, and we collaborated on verifying the text. We privately discussed that physicians today who claim to be skilled often attribute half their success to accumulating hidden merits and the other half to lifestyle management. However, dividing one's focus between spiritual accumulation and daily life may not fully align with the demands of medical practice. Moreover, the "hidden merits" they speak of are rarely achieved through diligent study of ancient classics and hard work. I, Yuan Zai, was listed among the military students, which distracted me from internal and external examinations, preventing me from learning my father's profound secrets of transforming one's constitution. Nevertheless, my father's lifelong diligence was solely focused on saving people and benefiting the world, striving to correct the biases of mediocre physicians, seemingly disregarding personal wealth. Through copying and compiling his works over the years, I deeply understood his singular and extreme dedication. Mr. Yike, who revered this book, frequently wrote to urge its publication and sent copies to official residences, hoping that contemporary kind-hearted individuals would assist in printing it to save lives and aid governance. This would honor Mr. Song Yuan's guidance for future learners and his mission to inherit the past and open up the future, fulfilling his grand aspirations. I, Yuan Zai, am clumsy and unlearned, unable to expound new theories in medicine or fully recount my step-father's legacy, nor can I adequately describe his expertise in formulas. Therefore, I bow respectfully and write this postscript.
