一医药关人之生死，经验丹方治病最灵。予素不知医、心甚契焉。搜采数十年，集成三千余方，内外治法具备。继
思内治汤饮，一匕入口，设不中病，挽回无及，因删去之。只存外治方一千五百有奇，门分别类，益以慎防疾病，法语
预诀，为集十卷。
一治病之法，辨证必兼察脉，但脉理甚微，浅学人，安得窥其 奥，寒热虚实之间，毫厘千里，苟貌为诊视，未辨
精微，颇多误事。若外治之法，按证用方，显而易见，效则捷于汤饮，即或不效，洗而去之，尚无大害，故专录以成集。
一释典谓∶人身病有四百四种，言病之多也。故古方杂制贴膏、涂丹、针灸、砭镰、浸洗、熨 、蒸提、按摩等外
治之法，与内治之方并行。予汇此集，非谓尽外治之法，可以废汤饮之剂也，不过取便于仓猝，使病者勿药有喜之意。
一是集原为救急而设，故方止录其简便者，以备用。若药价贵重而制法浩繁，不惟贫家艰于购求，即有钱亦难猝办
者，概置不载，且诸药名色，大半取寻常日用者，以便穷乡僻壤之人，一时无从觅取，以及人所难识草药，亦不敢载。
一是集不论居家行旅，仕宦皆宜随处批览，可以卫生，可以济世。倘有好善君子，翻刻广传，实所深望。
一予家勉业举制，医药之书不能全备，从人借阅，均多录方即还，不及覆核，其中纰缪良多，倘有指教，使得改正，
不至贻害，幸甚。
一古今丹方，罄竹难尽，一人搜罗有限。凡我同人，如有家藏简便方法，易以奏功者，幸祈钞授，以便续入补遗。
一方中分两制度，或有或无、或详或略，皆仍诸书之旧。
一凡先贤秘方，无从稽考。为某人所着者，必注见某书，以便考据。
天地怀有好生之德，圣贤存济世之心。因为好生，所以气凝结为五行，精凝聚为百草。因为济世，所以岐伯辨析药性，孙思邈制定方剂。像这样的丹方有益于人世，足以推广天地圣贤好生济世的心意，作为良医的辅助，难道只是小小的补益吗？当今圣明天子仁爱宽厚，包容天下，如雨露滋润万物，调和阴阳。百多年来，元气酝酿，太和之气翔洽。本来已经长久享受太平之福，多次显现人瑞之祥。然而仍然视百姓疾苦如己伤，爱护养育加倍周到。百姓痛苦困顿的情状，时常萦绕在圣上的思虑之中。这确实是想要使四海之内共同登上春台（太平盛世），进入寿域（长寿之境）。
程鹏程隐居庐山，亲身逢遇盛世，常常关切同胞。我曾刊刻《劝戒类钞》以警醒世人。如今他又怀着救苦的婆心，萌发活人的雅念，广泛搜集方书，悉心分类聚集，选择那些经过验证有效的，汇编成册，交付刻印，印刷流通。使得在穷乡僻壤之处，如果遇到病发昏夜，仓促延请医生不及的时候，翻阅此书对症用药，立刻能起死回生，难道不以此书为至宝吗？我希望读这本书的人，既然想医治别人的身体，必须先医治自己的心。有力的人，资助钱财以施送药物；无力的人，摘录内容以劝告同僚亲友。由近及远，将来家庭、国家、天下都受到益处。不仅不辜负天地圣贤的深心，而且恻隐慈爱之心也可以扩充，让天下人都达到仁寿的境界。我确实赞赏他的志向善良，于是乐意为他作序。
嘉庆癸亥年（1803年）三月上旬，写于深山澄观处，双口道人题写。
第一条：医药关系人的生死，经验证的丹方治病最灵验。我向来不懂医术，但内心非常认同。搜集采录几十年，集成三千多首方剂，内外治法具备。后来想到内治的汤剂饮片，一入口中，如果不中病，挽回就来不及了，因此删去了它们。只保留外治方一千五百多首，门类分别归类，加上慎防疾病、法语预诀，集为十卷。
第二条：治病的方法，辨证必须兼察脉象，但是脉理非常微妙，浅学之人，怎么能窥探其中的奥妙？寒热虚实之间，毫厘之差可能导致千里之谬，如果假装诊视，没有辨别精微，很多会误事。如果是外治的方法，按证候用方，显而易见，见效比汤饮快，即使无效，洗去也无大害，所以专门收录以成此集。
第三条：佛经说：人身有病四百四种，是说病之多。所以古方有杂制贴膏、涂丹、针灸、砭镰、浸洗、熨、蒸提、按摩等外治之法，与内治之方并行。我汇纂此集，不是说尽用外治之法就可以废除汤饮药剂，不过是取便于仓促应急，使病人有“勿药有喜”（不用吃药就高兴/痊愈）的意思。
第四条：此集原本是为救急而设，所以方剂只记录简便者，以备应用。如果药价贵重且制作法繁琐，不但贫家难以购买，即使有钱也难以仓促办理，一概不记载。而且诸药名色，大半取寻常日用之物，以便穷乡僻壤之人，一时无法觅取，以及人们难以识别的草药，也不敢记载。
第五条：此集不论居家或行旅，仕宦皆宜随处批阅，可以养生，可以济世。如果有好善君子，翻刻广传，实为所深切期望。
第六条：我家勉强从事科举学业，医药之书不能全备，从人借阅，大多抄录方剂后即归还，来不及复核，其中错误很多，如果有指教，得以改正，不至于贻害他人，幸甚。
第七条：古今丹方，罄竹难尽，一人搜罗有限。凡是我同好之人，如有家藏简便方法，容易奏效的，希望抄录传授，以便续入补遗。
第八条：方中的分两制度，或有或无、或详或略，都沿袭诸书的旧例。
第九条：凡是先贤秘方，无从稽考。为某人所著者，必定注明见于某书，以便考据。
Heaven and Earth possess the virtue of cherishing life, and sages harbor the heart to save the world. Because of cherishing life, Qi condenses into the Five Elements (Wu Xing), and Essence concentrates into hundreds of herbs. Because of saving the world, Qibo analyzed medicinal properties, and Sun Simiao formulated prescriptions. Such alchemical formulas benefit human society, sufficiently extending the benevolent hearts of Heaven, Earth, sages, and worthies to assist good physicians; is this not a significant contribution? Today, the Holy Emperor is sagely and benevolent, encompassing the universe, nurturing all things like rain and dew, and harmonizing Yin and Yang. For over a hundred years, Yuan Qi has been fermenting, and the Great Harmony (Tai He) permeates everywhere. Indeed, we have long enjoyed the blessings of peace, and frequently witnessed auspicious signs of longevity. Yet, he still views the people's suffering as his own injury, caring for them with double diligence. The painful and distressed conditions of the common people often occupy his royal thoughts. This is truly an intention to unite the realm in ascending to the Terrace of Spring (an era of peace) and entering the Realm of Longevity.
Cheng Pengcheng resides quietly at Mount Lu, personally witnessing the prosperous age, and always feels deep concern for his compatriots. I previously published "Quanjie Leichao" (Collection of Exhortations and Warnings) to awaken the deaf and blind. Now, driven by a compassionate heart to relieve suffering and a refined aspiration to revive lives, he has extensively collected medical texts, carefully categorized them, selected those proven effective, compiled them into a volume, had them printed, and circulated them widely. Thus, in remote villages, when illness strikes at night and there is no time to summon a doctor, one can consult this book, apply appropriate remedies, and instantly bring the dying back to life. Would this book not be considered a supreme treasure? I wish that those who read this collection, while intending to heal others' bodies, would first heal their own hearts. Those with means should donate funds to distribute medicines; those without means should excerpt content to advise peers and relatives. Starting from the near and extending to the far, eventually families, states, and the whole world will benefit. This will not only honor the profound intentions of Heaven, Earth, and sages but also expand feelings of compassion and love, enabling all under heaven to reach the realm of benevolence and longevity. I certainly appreciate his virtuous aspirations and am happy to write this preface.
Written in early March of the Guihai year of the Jiaqing reign (1803) at Chengguan Place in the deep mountains, by Shuangkou Daoren.
Article 1: Medicine and healthcare determine life and death; empirically tested alchemical formulas are most effective in treating diseases. I have never studied medicine, but my heart deeply agrees with its value. After decades of searching and collecting, I compiled over three thousand formulas, covering both internal and external treatments. Later, I reflected that internal decoctions and infusions, once ingested, cannot be retrieved if they fail to match the disease pattern, potentially causing irreversible harm. Therefore, I deleted them. I retained only over fifteen hundred external treatment formulas, categorized by type, supplemented with preventive advice and moral maxims, forming ten volumes.
Article 2: Methods of treating diseases require syndrome differentiation combined with pulse diagnosis. However, pulse theory is subtle; how can shallow learners penetrate its mysteries? Between cold, heat, deficiency, and excess, a slight error can lead to disastrous consequences. If one pretends to diagnose without discerning subtleties, many errors will occur. In contrast, external treatments involve applying formulas based on visible symptoms, which is straightforward. They act faster than decoctions, and even if ineffective, washing them off causes no major harm. Thus, I exclusively recorded these to form this collection.
Article 3: Buddhist scriptures state that the human body suffers from four hundred and four types of diseases, indicating the vastness of illnesses. Hence, ancient formulas include various external treatments such as plasters, paints, acupuncture, bian stone therapy, scarification, soaking, warming, steaming, and massage, running parallel to internal treatments. My compilation does not imply that external methods can replace decoctions; rather, it aims to provide convenience for emergencies, offering patients the joy of recovery without necessarily needing medication ("wu yao you xi").
Article 4: This collection was originally designed for emergency rescue; therefore, only simple and convenient formulas are recorded for备用 (backup use). Formulas with expensive ingredients or complex preparation methods are excluded, as poor families cannot afford them, and even wealthy ones may find them difficult to procure urgently. Moreover, most ingredients listed are common daily items, suitable for remote areas where rare herbs might be hard to find or identify. Uncommon or hard-to-identify herbs are intentionally omitted.
Article 5: This collection is suitable for reading at home or during travel, for officials or commoners alike. It promotes health and benefits society. If benevolent gentlemen reprint and widely disseminate it, this would be deeply hoped for.
Article 6: My family focused on imperial examinations, so our medical books were incomplete. Borrowed texts were copied hastily and returned without verification, leading to many errors. Any corrections offered would be appreciated to prevent harm.
Article 7: Ancient and modern alchemical formulas are countless, beyond the scope of one person to collect. Fellow enthusiasts possessing simple, effective home remedies are requested to copy and share them for inclusion in future supplements.
Article 8: Dosage systems in formulas vary—some present, some absent, some detailed, some brief—all following the original sources.
Article 9: For secret formulas of past sages that cannot be traced to specific authors, notes will indicate the source book for verification purposes.
