道光十有九年岁次己亥花朝后一日桐乡孙学诗谨序于吴门之石泉古舍。
古人有话说：“左手拿着天下的地图，右手割断自己的喉咙”，即使是愚笨的人也不会这样做。为什么呢？因为天下虽然广大，却不如我们自己的身体珍贵。所以，天下间有关于心性修养的书籍，是决定人心生死存亡的关键；而关于医药的书籍，则是决定人身生死存亡的关键。因此，在六经和四子（指《大学》《中庸》《论语》《孟子》）之后，没有比医药书籍更珍贵的了。
神农氏在上药、中药、下药方面进行了细致的辨别，《周礼》中留下了关于五气、五色、五声的训诫。自古以来的圣贤明智之士，没有不留心于这些领域的。如今所谓的喉科，只是大方脉中的一个分支罢了，然而它的生死决断往往只在数日之间，安危判断就在顷刻之时。其关系最为重大，但世上从事这一科的人，大多学问没有根基，得不到真正的传承，拘泥于寒凉药物，固守偏见，有见识的人是不允许的。
我的同乡郑梅涧先生，生性喜好岐黄之术（中医）。他的祖先得到了喉科的秘传，因此他在这方面尤为精通。远近之人没有不知道他的。他救活垂危、起死回生的案例，数不胜数。我曾常见到他救治濒临死亡的患者，针刺患者颈部放出如墨汁般的黑血，患者便豁然痊愈。他的医术如此奇妙，却从未接受过别人一丝一毫的报酬，只把方便他人作为急务，这大概也是范文正公（范仲淹）、陆忠宣（陆九渊）那样的心意吧。
先生非常珍视这本书，又担心有人趁人之危谋取利益，所以未曾传授给别人。我有幸阅读了一部分，因此高兴地写了这篇序言。天下最宝贵的器物，珍爱生命的人不会用身体去交换它；而这本书记载的恩泽与利济无穷无尽，那么它的贵重程度应当是怎样的呢？
嘉庆乙亥年春天，我在家闲居无事，每天取出医书细细品味。恰逢朋友来访，拿出《重楼玉钥》给我看，说：“这本书没有刻印本，你抄录一册保存阅读。”于是我接受过来阅读，恍然有所领悟。后来凡是遇到喉症，可惜当时不懂针灸，仅按方投药，无不神奇灵验。乡里人知道有此书时，借来抄写，但流传并不广泛。其中错别字很多，指不胜屈，我只是凭意思修改订正了一两处，其余则保留原样。原序没有署名，称作者为郑梅涧先生，也不知道他是哪里人。然而他的辨证施治，各具神妙，如果不是怀着济世救人的慈悲心肠，谁能做到这样呢？
今年夏天，我们天津地区时疫流行，患喉症的人极多，而治疗方法不得当，往往导致受害。我闭门修养，未能遍告邻里，心中暗自惭愧。于是与弟弟们商量，将此书的稿本再抄录一份，寄到苏州（吴门），委托孙朴斋君校订，交付刻印。那么此后人人都有指南可依，患者即使不延请医生，只要对照症状检查药方，想必也不会夭折枉死，我的心也就稍微安慰了。
道光十八年岁次戊戌年仲秋上旬，天津冯相识记。
人的全身，各种病症都可能危及生命，唯独咽喉的病症更是危险中的危险。不到煮一顿饭的时间就可能毙命，可以立刻等待死亡的到来。即使居住在良医附近，刚发病就治疗，还后悔太晚，更何况是在山林荒僻的地方，那就更不用说了。我很怜悯这种情况。我不懂医学，但对于那些古方中百试百效、被众人传播的药方，我都亲手抄录成册，有的刊附在善书中，有的印刷成单页赠送给人。
咽喉科一门流传下来的书，应当不下数十种。唯独喉科经验秘传，经过程瘦樵君定本，业此科的大半人都尊奉它。大家都认为除此之外很少有能与之匹敌的。有一天，黄竹亭君从天津寄信给我，说冯石农、丹崖兄弟秘密收藏着《重楼玉钥》一书，这是喉科的指南，急切想要付梓出版，以公之于世。而附近缺少好的工匠，您客居苏州很久，应该容易找到合适的人选，而且您也乐意做这件事，常常觉得时间不够用。我想私下拜托您做这件事，可以吗？
我听了之后欣喜若狂，急切想看到这本书，希望这本书能迅速完成并广泛流传于世。催促他寄给我，不到两个月书就到了。书中无论是针法还是药法都完备齐全，足以弥补《经验秘传》所不及的地方，确实是喉科中前所未见的佳作。于是我为之选择工匠开雕，谨慎校对，以期不辜负好友的委任，也符合好友济世的慈悲之心。
竹亭以前曾与我一同客居北京（燕台），后来客居苏州，又在阊门、由拳里居住，我们都共用几案砚台，气味相投，毫无隔阂，确实是一位谦逊有礼的君子。丹崖与我曾在京城寓所见过面，他乐善不倦，见义必为，这种品质常流露在眉宇之间。他的哥哥石农是我一直想见而未能见到的，但我听说他在山西任职时，有能干官吏的名声，百姓称颂他为“再生父母”（生佛）。我本来就深信不疑，况且现在通过与他弟弟共同刊刻此书，更加相信他了。
书成后，向我索求序言。我不懂医学，又怎么敢评论医学的书呢？然而这本书确实是百试百效、应当被众人传播的。我私下希望用尽竹子来印制这本书，使人人携带此书以防患于未然。不仅仅是山林荒僻、不能进入市场买药的人，简直就像家里有一个医生一样；即使是居住在良医附近的人，有了这本百试百效的书，也比登门求取那万分之一可能有效的医术要好得多。这就是石农诸位君刊刻此书的用意啊。
道光十九年岁次己亥花朝节后一日，桐乡孙学诗谨序于苏州的石泉古舍。
The ancients said, "Holding the map of the world in the left hand and cutting one's own throat with the right," even a foolish person would not do this. Why? Because although the world is vast, it is not as precious as our own bodies. Therefore, among all books in the world, those concerning mental and moral cultivation determine the life and death of the human mind, while those concerning medicine (Yi Xue) determine the life and death of the physical body. Thus, after the Six Classics and the Four Books, there is nothing more precious than medical texts.
Shennong distinguished between superior, medium, and inferior herbs; the *Rites of Zhou* provided instructions on the Five Qi, Five Colors, and Five Sounds. Since ancient times, sages and wise men have never failed to pay attention to these fields. The so-called Throat Department (Hou Ke) today is merely one branch within general internal medicine (Da Fang Mai). However, decisions regarding life and death in this department are often made within days, and judgments of safety or danger are made in moments. Its significance is paramount, yet practitioners of this specialty today often lack a solid foundation in learning and fail to receive authentic transmission. They rigidly adhere to cold-natured remedies and hold biased views, which those with insight do not condone.
My fellow townsman, Mr. Zheng Meijian, had a natural inclination towards Traditional Chinese Medicine (Qi Huang Jia Yan). His ancestors received secret transmissions of throat treatments, making him particularly proficient in this area. People near and far know of him. He has saved countless lives from critical conditions and brought the dying back to health. I have often seen him treat patients on the verge of death by needling their necks to release blood like ink, resulting in immediate and complete recovery. His skill was so miraculous that he never accepted even a small token of gratitude from others, prioritizing the benefit of people above all else. This attitude likely reflects the spirit of Fan Zhongyan and Lu Jiuyuan.
Mr. Zheng cherished this book highly and, fearing that others might exploit crises for profit, did not transmit it to anyone. Having the fortune to read parts of it, I joyfully wrote this preface. The most valuable items in the world are such that those who revere life would not exchange their bodies for them. Given that the benefits of this book are infinite, how precious must it be?
In the spring of the Yihai year of the Jiaqing era, while I was at home with leisure, I spent my days studying medical texts. A friend visited and showed me the manuscript of *Chonglou Yuyao* (Jade Key of the Heavy Tower), saying, "This book has no printed edition; please copy a set for your reference." I accepted it and read it, experiencing sudden enlightenment. Later, whenever I encountered throat disorders, lacking knowledge of acupuncture at the time, I relied solely on herbal prescriptions, achieving miraculous results every time. When villagers learned of this book, they borrowed it to copy, but its circulation remained limited. There were numerous typographical errors, too many to count. I corrected only a few based on context, leaving the rest unchanged. The original preface bore no name, referring only to the author as Mr. Zheng Meijian, and his origin remains unknown. Nevertheless, his differentiation of syndromes and application of treatments possessed divine subtlety. Who but one harboring a compassionate heart for saving the world could achieve such results?
This summer, an epidemic swept through Tianjin, causing a high incidence of throat disorders. Due to improper treatment methods, many suffered harm. I stayed indoors cultivating myself and could not warn all neighbors, feeling privately ashamed. Thus, I discussed with my younger brothers the plan to copy the manuscript again, send it to Suzhou (Wu Men), entrust Mr. Sun Puzhai with proofreading, and submit it to printing. In this way, everyone will have a guide. Patients, even without consulting a doctor, can check symptoms against the formulas and avoid premature death, bringing some comfort to my heart.
Recorded by Feng Xiang in Tianjin during the early part of the mid-autumn month of the Wuxu year, 18th year of Daoguang.
Various diseases in the human body can lead to critical conditions, but throat disorders are critically dangerous among the critical. Death can occur before millet is cooked. Even if one lives near a skilled physician and seeks treatment immediately, one still regrets acting late. How much worse must it be in remote, mountainous areas? I deeply pity this situation. Although I am not a physician, I have hand-copied ancient prescriptions that have proven effective hundred times over and are widely circulated. Some are included in benevolent books, others printed on single sheets to give away. Dozens of books on throat care have been transmitted. Among them, *Experience Secret Transmission of Throat Care*, finalized by Mr. Cheng Shouqiao, is largely followed by practitioners in this field. It is generally considered unmatched by others.
One day, Mr. Huang Zhuting sent a letter from Tianjin stating that Mr. Feng Shinong and his brother Dan Ya secretly possessed *Chonglou Yuyao*, a guide for throat care, and urgently wished to publish it for the public. Finding good craftsmen nearby was difficult, but since Mr. Huang had resided in Suzhou for a long time, he should easily find suitable help. Moreover, he seemed eager to undertake this task. I asked if he could handle this matter.
Hearing this, I jumped for joy, eagerly anticipating the book's completion and widespread distribution. I urged him to send it to me. Within two months, the book arrived. It comprehensively covered both acupuncture and herbal methods, supplementing what *Experience Secret Transmission* lacked. It was truly a unique and unprecedented work in throat care. I selected craftsmen for carving blocks and carefully proofread the text, hoping to live up to my friend's trust and his compassionate intention to save the world.
Zhuting had previously lived with me in Beijing (Yan Tai) and later in Suzhou, sharing desks and inkstones, with compatible temperaments and close friendship, behaving as a modest gentleman. I had met Dan Ya in the capital; he was tirelessly charitable and righteous, qualities evident in his demeanor. His elder brother, Shinong, was someone I longed to meet but had not. However, hearing of his reputation as an capable official and the praise he received as a "living Buddha" in Shanxi, I already believed in his virtue. Now, through co-publishing this book with his brother, my belief is strengthened.
Upon completion, the book requested a preface from me. As I am not a physician, how dare I comment on medical texts? Yet, this book is indeed effective in every trial and worthy of wide dissemination. I privately wish to print it extensively so that everyone carries it to prevent illness before it arises. Not only will those in remote areas unable to access markets have a doctor in their homes, but even those living near physicians will find this reliable book superior to seeking the rare chance of success from a doctor's door. This is the intent of Mr. Shinong and his colleagues in publishing this book.
Respectfully prefaces by Sun Xuexi from Tongxiang on the second day after the Flower Festival in the Jihai year, 19th year of Daoguang, at Shiquan Ancient Residence in Suzhou.
