乾隆丁丑岁三月上巳日澉水吴仪洛遵程书于硖川之利济堂
我家祖上藏书非常丰富。凡是有益于百姓民用的书籍，购买得尤为急切。因此，关于岐黄（中医）方面的言论，也有很多是海内外罕见的版本。我从小时候起，在研习科举考试文章时，就广泛涉猎这些书籍。每当遇到有心得领悟之处，就觉得精神舒畅、心境澄澈。于是我将家中收藏全部取出，精心研读。到现在已经四十年了。医学的要领，没有比明白医理更优先的，其次在于辨证，再次在于用药。如果医理不明白，根据什么来辨证呢？如果不能辨证，根据什么来用药呢？所以我拙作《医学十种》，第一种叫“一源必彻”（必须彻底探究医理本源），第二种叫“四诊须详”（望闻问切四种诊法必须详尽）。对于经典义理和病情，一定要斟酌各家之言，以求达到最恰当的境界。我又想到，上天产生药物，全是为了救济世人的疾苦。有一种病，必然有一种药对应。如果用药不当（眩指迷乱、误用），普通的药物都可能伤人，何况那些药性最为偏颇驳杂的呢？自古以来注释本草的人，从古代经典以下，历代都有增补修订，而李时珍的《本草纲目》是集大成的著作。它的考证依据详尽完备，足以弥补《尔雅》和《诗经疏》的缺失，从而满足医学使用的需要。有人嫌它稍微繁琐，接着进行删减的是缪希雍的《本草经疏》，不仅阐述药物的功能，还兼论其缺点劣处，其中有很多发明创造。而西昌的喻嘉言对此颇有异议。最后是新安汪昂，继承前二书，编写了《本草备要》一卷，篇幅不繁，但采集编辑非常广泛，适宜成为近代广为流传的书籍。只可惜他本非岐黄世家，不亲自临证诊断而专门相信前人，杂乱采录各种说法，没有加以折中判断，未免有沿袭错误的失误。我不自量力，固守浅陋，选取这本书重新修订。因循旧有的占一半，增加修改的占一半。旁征博引旧文，参酌自己的临床经验，以扩充未尽的宗旨。书成之后，命名为《本草从新》，交付刻印出版，希望它能切合实际使用，从而能够辅助古人的著作。其余几种书，将依次刊布，与有见识的人商讨。
乾隆丁丑年三月初三日，澉水人吴仪洛遵照程氏（或指遵循某种规范/人名，此处依原文直译）在硖川利济堂书写。
My ancestors' library was extremely extensive. Books beneficial to the people's livelihood were purchased with particular urgency. Consequently, there were many rare editions of texts on Qihuang (Traditional Chinese Medicine) that were seldom seen inside or outside the country. Since my childhood, while studying for the imperial examinations, I had already read these works extensively. Whenever I encountered passages that resonated with me, I felt my spirit become clear and my mind purified. Thus, I brought out all my collections and studied them meticulously. It has been forty years since then. The essence of medicine lies first in understanding principles, secondly in syndrome differentiation, and thirdly in medication. If principles are not understood, how can syndromes be differentiated? If syndromes are not differentiated, how can medications be applied? Therefore, in my humble work "Ten Medical Treatises," the first is titled "Thoroughly Understanding the Source" (insisting on thoroughly comprehending the fundamental origins of medical theory), and the second is titled "Detailed Four Diagnostic Methods" (requiring detailed application of inspection, auscultation/olfaction, inquiry, and palpation). Regarding classical meanings and clinical conditions, one must deliberate among various opinions to achieve the most appropriate conclusion. Furthermore, I reflect that Heaven produces herbs to relieve human suffering. For every disease, there corresponds a specific herb. If used incorrectly (misapplied or confused), even ordinary herbs can harm people, let alone those with the most extreme and unbalanced properties. Since ancient times, commentators on Materia Medica have added revisions generation after generation from the classic texts onward. Li Shizhen's *Bencao Gangmu* (Compendium of Materia Medica) represents the culmination of this effort. Its evidence is comprehensive and thorough, sufficiently supplementing the deficiencies of *Erya* and the commentaries on the *Classic of Poetry*, thereby serving medical needs. Some found it slightly too voluminous; subsequent abridgers included Mu Xi-yong's *Bencao Jing Shu* (Abridged Classic of Materia Medica), which not only describes the functions of herbs but also discusses their shortcomings, offering many insights. Yu Jia-yan from Xichang raised considerable objections to this. Finally, Wang Ang from Xin'an followed these two books and compiled *Bencao Beiyao* (Essential Reference for Materia Medica). Though concise in volume, its compilation was extensive, making it a widely appreciated book in recent times. Unfortunately, he was not from a Qihuang family lineage, relied solely on predecessors without clinical experience, indiscriminately collected various theories without critical synthesis, and inevitably inherited errors. Presuming upon my own limited knowledge, I selected this book for revision. Half remained as originally written, and half was increased or modified. I drew upon old texts and incorporated my own clinical experiences to expand upon incomplete points. Upon completion, the book was named *Bencao Congxin* (New Compendium of Materia Medica) and submitted for printing, hoping it would be practical for contemporary use and serve as a wing to assist the ancients. The remaining several treatises will be published sequentially for discussion with knowledgeable individuals.
