三家医案者，叶天士布衣，薛生白征君、缪宜亭进士之所作也。青囊一肩，紫书三卷，
壶公
待用无遗；牛溲马勃，收藏不弃。盛以竹节，量以刀圭。赤箭 于云根，红盐拂于灶上。明
珠耻其价，金镜惭其形。杏林之树，以董奉而益珍；橘井之泉，非苏耽其谁凿。游刃恢乎，
奏刀 然，无枝经肯綮之忧，得批却导 之要。今虽扁卢已杳，和缓云遥，郭玉之针靡传，
淳意之经失授，而问秘书于金匮，鼠迹犹存，抄禁方于龙宫，蠹蚀未尽，傥不搜之石室，镌
以玉版，则桃胶莫问，金浆遂漓，安能唤三折之肱，起一肱之土，续已断之琴弦，补久亡之
笙诗乎。此莺湖吴子音先生，所以有合刻之选也。先生以民胞为怀，婆心救世，赤饼胸纳，
青芝手采，五行精理，六气辨淫，心源接俞跗之传意，学探允宗之妙，岁活人以万计，日扪
心无一疵。固已严州道上，争颂桐君。成都市中，惟寻韩伯矣。乃当夫春雨初过，药苗微香
，花拂帘垂，茗熟炉沸，茶烟袅于帐后，砚云起于池中。簟滑瓯甘，窗疏几净。爰翻玉轴，
细检牙签。考阴阳之和，按升沉之度，攻必腠理，位必君臣，总思邈之《千金》，资葛洪之
万卷，莫不明折虫翼，细察蚊睫，着解颅理脑之效，显涤胃湔肠之能，洵可以寿诸枣梨，观
其草木焉。今天秘术不宣者，庸医之窄量也；着书行世者，良医之苦心也。设或箧藏内典，
枕贮《灵枢》，窃巫彭之制，而号为己能，抱岐伯之书，而矜为独得，则春风已歇，兰草孤
芳，抱朴虚传，简文空劝。竟没飞仙之迹，难言妙道之公，乃先生则玉字亲编，金针暗度，
潜消 ，广被太和，其心可不谓美哉!其利于是乎溥矣。长春少有痼疾，长习微 ，药性
粗谙，方书渐熟，命含毫而撰序，遂濡笔而成章。嗟拙陋之无文，恐揄扬之未善，神君活我
，医者原存割股之心，贤士知余，狂夫难疗看花之癖。
道光辛卯九月既望愚侄乌程陆长春瓣香氏谨撰
《三家医案》一书，是叶天士（平民身份）、薛生白（征君，即被朝廷征召而不就的学者）和缪宜亭（进士出身）三位先生的著作。他们行医时肩挑药囊，随身携带三卷珍贵的医书；对于各种药材，无论是名贵的还是像牛溲、马勃这样廉价的，都收藏起来毫不嫌弃。将药材盛放在竹节容器中，用量时使用刀圭（古代量取药末的工具）。采集赤箭（天麻）于云根（山石间），在灶上拂去红盐（硇砂）的灰尘。这些医术之珍贵，连明珠也自惭其价值，金镜也羞愧其形态。杏林中的树木，因为董奉的医德而更加珍贵；橘井中的泉水，除了苏耽还有谁能开凿呢？他们的医术运用自如，挥刀解剖时从容不迫，没有遇到经络筋骨交错处的担忧，掌握了剖析肯綮（筋骨结合处）的要领。如今虽然扁鹊、卢医已经远去，华佗、缓公也已遥远，郭玉的针法没有流传下来，淳意的经学失传了，但如果向金匮（指代医学典籍或秘府）询问秘籍，鼠迹依然存在；从龙宫抄录禁方，蛀蚀尚未完全毁坏。如果不将这些医案搜罗整理刻印在石室中，镌刻在玉版上，那么桃胶便无人问津，金浆也随之淡薄流失，怎么能唤醒拥有“三折肱”（多次治病有经验）能力的良医，让土地复苏，续接已断的琴弦，补全久已亡佚的笙诗呢？这就是莺湖吴音先生决定合刻这三家医案的原因。吴先生心怀百姓如同胞，以慈悲之心拯救世人，胸怀如同容纳赤饼般宽广，亲手采摘青芝，精通五行精微的道理，辨析六气的淫邪变化，心法承接俞跗的传承意旨，学问探求允宗的奥妙，每年救治的人数以万计，每天扪心自问没有瑕疵。他确实已经在严州道路上，让人们争相歌颂桐君（医药之神）；在成都街头，人们只寻找韩伯（指代名医）。恰逢春雨初过，药苗散发微香，花朵拂动帘幕低垂，茶煮好了炉火沸腾，茶烟在帐后袅袅升起，砚台中的墨云从池中升起。竹席光滑，茶碗甘甜，窗户疏朗，几案洁净。于是翻开玉轴（指珍贵的书籍），仔细检查牙签（书套上的标签）。考察阴阳的和谐，按度量的标准升降沉浮，攻邪必针对腠理（皮肤肌肉的纹理间隙），处方地位必须讲究君臣佐使的关系。总括孙思邈的《千金方》，借助葛洪的万卷藏书，无不明察秋毫，细致入微，展现出解颅理脑的功效，彰显涤胃洗肠的能力，这确实可以刻印出版，供人观赏其中的草木药理。如今秘术不公开，是庸医心胸狭窄的表现；著书立说流传于世，是良医的一片苦心。如果将内典藏在箱箧中，把《灵枢》贮存在枕边，窃取巫彭的制药技术却号称是自己的才能，抱着岐伯的书却夸耀为独家心得，那么春风已经歇息，兰花独自芬芳，抱朴守真的传说虚传，简文帝劝学的空话徒劳。最终掩盖了飞仙的踪迹，难以言说妙道的公正。然而吴先生则亲自编写玉字（指精美的文字或医案），暗中传授金针（指高明的医术），潜移默化地消除疾病，广泛传播太和之气，他的心难道不美好吗！他的利益因此普及天下。我长春年少时有顽固的疾病，长大后学习浅显的医术，对药性粗略熟悉，对方书逐渐熟练，受命含笔撰写序言，于是蘸笔写成文章。感叹自己拙劣浅陋缺乏文采，恐怕赞扬得不够好。神君救活了我，医者原本存有割股（割下大腿肉）救人的心志，贤士了解我，狂夫难以治愈看花的癖好。
道光辛卯年九月十六日，愚侄乌程陆长春瓣香氏恭敬撰述。
*Sanjia Yi'an* (Collected Medical Cases of Three Masters) comprises the works of Ye Tianshi (a commoner), Xue Shengbai (a *Zhengjun*, a scholar refused official appointment by the court), and Miao Yiting (an *Jinshi*, degree holder). Carrying the *Qingnang* (green bag, symbolizing medical skills) on one shoulder and preserving three volumes of *Zishu* (purple books, symbolizing precious medical texts), they were as prepared as Hu Gong, leaving nothing unused; even humble herbs like *Cheqiancao* (Plantago seeds, literally "donkey urine") and *Mapo* (Lycoperdon, literally "horse boletus") were collected without abandonment. Herbs were stored in bamboo joints and measured with *Daogui* (knife-scoop, an ancient measuring tool). *Tianma* (Gastrodiae Rhizoma, literally "red arrow") was gathered from cloud roots (high mountain rocks), and red salt was brushed upon the stove. Their skill was so profound that pearls felt ashamed of their value, and golden mirrors felt ashamed of their form. The trees of the Apricot Grove became more precious because of Dong Feng; the spring of the Orange Well was dug only by Su Dan. Their manipulation of medical techniques was expansive and free, their blade work smooth and effortless, avoiding the worry of hitting tough sinews and bones, grasping the essence of dissecting complex structures. Although Bian Que and Lu Yi are long gone, and He Huan and Chun Yi are distant, Guo Yu's acupuncture methods untransmitted, and Chun Yi's classics lost, if we inquire into secrets from the Golden Cabinet (*Jinkui*), rat traces remain; if we copy forbidden prescriptions from the Dragon Palace, worm-eaten pages are not yet exhausted. If these cases are not searched for in stone chambers and engraved on jade tablets, then peach gum will be unasked for, and golden elixir diluted. How can we awaken the wisdom of "three broken arms make a good doctor," revive the land of medicine, mend broken zither strings, or supplement lost shi poems? This is why Mr. Wu Yin of Yinghu chose to compile these three masters' cases together. Mr. Wu harbors compassion for all people as his own kin, saving the world with a benevolent heart, carrying the ambition of red cakes, hand-picking green lingzhi, mastering the subtle principles of Five Elements (*Wuxing*), and distinguishing the excesses of Six Qi (*Liuqi*). His mind connects to the transmission of Yu Fu, and his learning explores the wonders of Yun Zong. Annually he saves thousands, and daily he checks his conscience with no flaw. On the road of Yanzhou, people compete to praise Tong Jun; in Chengdu market, one seeks only Han Bo. Just after spring rain, medicinal seedlings emit faint fragrance, flowers brush against hanging curtains, tea boils in the stove, smoke curls behind curtains, ink clouds rise from the pond. Bamboo mats are smooth, tea bowls sweet, windows airy, tables clean. Thus, he turns over jade scrolls, carefully inspects ivory tags. He examines the harmony of Yin and Yang, measures the degrees of ascending and descending, attacks pathogens targeting the *Coulī* (interstices of skin and muscle), positions formulas according to Sovereign, Minister, Assistant, and Envoy roles. He synthesizes Sun Simiao's *Qianjin Fang* and benefits from Ge Hong's ten thousand volumes, observing details as small as insect wings and mosquito eyelashes, demonstrating efficacy in treating cranium and brain conditions, revealing abilities to cleanse stomach and intestines. Truly, this can be printed on dates and pears for public viewing, observing the properties of herbs and plants. Today, those who keep skills secret out of narrow-mindedness are mediocre doctors; those who write books for the world show the painstaking efforts of good doctors. If one hides internal canons in boxes, stores *Lingshu* under pillows, steals Wu Peng's formulations claiming them as one's own ability, holds Qibo's books boasting exclusive acquisition, then spring breeze ceases, orchid flowers stand alone, embracing simplicity becomes a false legend, and Jianwen's advice is vain. Ultimately, traces of flying immortals are lost, and the fairness of profound Dao cannot be spoken. However, Mr. Wu personally compiles jade characters, secretly passes golden needles, subtly eliminating disease, widely spreading Great Harmony (*Taihe*). Is his heart not beautiful? Are his benefits not extensive? I, Changchun, had chronic illness in youth, studied subtle medicine in adulthood, roughly understood herb properties, and gradually mastered prescription books. Ordered to write the preface, I dipped my brush to complete this chapter. Lamenting my clumsiness and lack of literary talent, fearing my praise is insufficient. Divine Lord saved me; originally, healers possess the heart to cut flesh for parents; sages know me; a madman finds it hard to cure his passion for watching flowers.
Respectfully written by your humble nephew Lu Changchun of Wucheng, Baxiang Shi, on the 16th day of the 9th month of the Xinmao year of Daoguang.
