先伯父羲桐先生，以制举之学，着声艺林，垂六十年，学人览其遗文，望洋而叹。意谓先生毕生之
精力，殆竭于此，而弗暇以他及。而不知自其少壮喜读方书，五色奇咳，术随年进。洎乎手订《治裁》书，
壹志殚心，与老病相终始，固自有不朽之业，而如是乎身心以之者在也。今夫方伎之事， 久失传，则益肆为
鄙诞，以相煽惑，独医学以切于民生日用，理近而事常，得以相缘于勿替。自仲景着方，后贤缵而衍之，
汤液之功，遂加于针石，未可谓所传之不永矣。然而玉版真言，灵兰秘典，儒者弗问，医亦舍旃，证若茧丝，
法同射覆，所施失当，视他方伎，为祸尤烈，则岂非不学之咎哉。然且果于自信，率其谬误，出应人急，
吁可悲矣！先生熟精《灵》、《素》之言，因遂博观仲景以下诸名家书，既已穷极源流，然犹深自韬晦，
游迹所至，有主宾数年无识其能医者。里居日久，数察奇恒，声誉所归，丐请至莫可却，则慨然以生人自任，
羸童贫叟，匍匐偕臻，靡不乐效其术。乃至富家大族，介其所亲，延缘造请，辄十不一二应。曰∶彼岂借仆
生之者。其不屑于应酬如此。是书稿凡数易，尝语植本曰；着书贵适于用，吾年老，且用吾术生人固不尽，
吾书成，庶救时之心与无终极耳。又曰∶近世名家着述，其号为集大成者，卷帙繁富，学人恒惮于诵习，
又或主辨析名理治法，弗取其备，中材之士，亦无由就一人一证而悟其全。吾书务言简意赅，使人开卷了然而
已。呜乎！此殆即先生晚年刊落浮华，粹然有用之言乎。植本愚懵无识，于先生着述精意，不能有所阐发，第
就先生勤于学术，而慎于用术之实，以及当时辟 之言涉是书者着于篇，俾读者
有所据以考焉。先生生时，子芝本方习科举，先生未尝授以医。及卒，而求医者谓当有异闻，仍踵相接，
不得已，循是书成法以应求者，而所投辄验。所以勉勉于是刻者，又岂徒存先人手泽之意云尔哉。

我的伯父羲桐先生，凭借科举之学在文人学界享有盛名，长达六十年。求学之人阅读他的遗留文章，往往望其项背而感叹。人们认为先生毕生的精力，大概都耗费在这上面了，而没有闲暇顾及其它方面。却不知道他从年轻壮年时就喜欢阅读医书，面对各种复杂的病症（五色奇咳），医术随着年份增长而精进。等到他亲手编订《类证治裁》这部书时，专心致志，耗尽心血，与年老多病相伴始终，这自然是不朽的功业，像这样身心投入其中的人啊。
如今那些方技之事，如果长久失传，就会更加肆意地变得鄙陋荒诞，互相煽动迷惑。只有医学因为切近百姓日常生活，道理浅近且事务平常，得以延续而不衰败。自从张仲景撰写方书以来，后世的贤能之士继承并发展它，汤液（中药汤剂）的功效，于是超过了针石（针灸），不能说所传承的不长久。然而，《玉版》、《灵兰秘典》等深奥的真言，儒家学者不过问，医生也舍弃不用，辨证如同理茧抽丝般细致，诊法如同猜谜射覆般难测，如果施用不当，比起其他方技，造成的祸害尤为严重，这难道不是不学习的过错吗？
然而有些人固执自信，率领着谬误，出来应对人们的急难，唉，真是可悲啊！先生熟读精通《黄帝内经·灵枢》和《素问》的言论，于是广泛阅览张仲景以下各位名家的书籍，已经穷尽了源流，但仍然深深地韬光养晦，游历足迹所到之处，有作为主客数年相处却没有人知道他是擅长医术的人。在家居住时间久了，多次观察常人及异常病患，声誉归附于他，求医乞药的人多到无法拒绝，他便慷慨地以拯救世人为己任，瘦弱的儿童和贫穷的老人，匍匐跟随而来，没有不乐意施展他的医术的。以至于富贵大户人家，通过他们的亲戚朋友，沿着路径来邀请请教，十次也不回应一两次。他说：“他们难道是借我这条命来生存的吗？”他对这种应酬如此不屑。这本书稿凡几次修改，曾经告诉植本说：著书贵在适合实用，我年纪老了，况且用我的医术救人固然不能救尽，但我的书写成后，或许救时之心就没有终极了。又说：“近代名家著作，那些号称集大成的，卷册繁多丰富，求学之人常常害怕诵读学习，又或者主要辨析名理治法，不追求完备，中等才智的人，也没有途径从一个人一个证候上领悟全貌。我的书致力于言语简练意思完备，让人打开书卷就能明白而已。”
唉！这大概就是先生晚年刊落浮华，纯粹是有用的言论吧。植本愚笨无知，对于先生的著述精意，不能有所阐发，只是根据先生勤于学术，以及谨慎使用医术的实情，还有当时辟谣之言涉及本书的内容记载在篇中，使读者有所依据来考证。先生在世时，儿子芝本正在学习科举，先生未曾传授他医术。等到先生去世，求医者说应当有异闻（指继承衣钵或特殊疗效），仍然接踵而至，不得已，遵循这本书成法来应对求医者，而所投用的药辄有效验。所以勉力进行这次刻印，又哪里仅仅是保存先人手泽的意思呢？
时间是咸丰元年岁次辛亥端阳前二日，侄植本谨撰。
My late uncle, Mr. Yitong, gained fame in the literary world through his success in the imperial examinations (Keju), a reputation that lasted for sixty years. Scholars who read his posthumous writings often sigh with admiration at the vastness of his achievement. It was generally believed that his lifelong energy had been exhausted in this endeavor, leaving him no time to attend to other matters. However, they were unaware that from his youth and prime, he enjoyed reading medical texts; facing various complex symptoms (such as abnormal discharges and coughs indicated by five colors), his medical skills advanced with the years. When he personally compiled the book *Leizheng Zaicai* (Categorized Treatments Adapted), he devoted himself wholeheartedly, spending his life amidst old age and illness. This naturally constituted an immortal legacy, achieved by one who dedicated his body and mind thus.
Currently, many arts and crafts have long been lost, leading to increasingly vulgar and absurd practices that deceive people. Only medicine, being closely related to daily life, with principles that are proximate and affairs that are common, has continued without interruption. Since Zhang Zhongjing wrote his formularies, later sages inherited and expanded upon them. The efficacy of decoctions (Tangye) surpassed that of acupuncture and moxibustion (Zhen Shi). Thus, it cannot be said that the transmission is not enduring. However, profound truths found in texts like *Yuban* and *Linglan Midian* are ignored by Confucian scholars, and even physicians abandon them. Differentiation of syndromes is as intricate as unraveling cocoons, and diagnostic methods are as elusive as guessing hidden objects. If applied improperly, the harm caused is more severe than that of other arts. Is this not due to ignorance?
Yet, some are overly confident, propagating errors while attempting to address people's emergencies. Alas, how tragic! My uncle was well-versed in the *Lingshu* (Spiritual Pivot) and *Suwen* (Basic Questions) of the *Huangdi Neijing*. He subsequently studied extensively the works of famous masters from Zhang Zhongjing onwards, thoroughly understanding their origins and developments. Nevertheless, he remained humble and obscure. During his travels, there were instances where hosts and guests lived together for years without realizing his medical expertise. After residing in his hometown for a long time, he frequently observed both ordinary and exceptional cases. As his reputation grew, requests for treatment became too numerous to refuse. He then generously took upon himself the responsibility of saving lives. Weak children and poor elderly people would crawl to him, and he gladly practiced his art on them. Even wealthy families, introduced by relatives, sought him out, but he responded to only one or two out of ten invitations. He said, "Do they think I can grant them life?" He showed such disdain for social obligations.
The manuscript underwent several revisions. He once told me, Zhiben: "Writing books should prioritize practical utility. I am old, and although my medical practice cannot save everyone, once this book is completed, my heart's desire to aid the times will have no end." He also said, "Contemporary masterpieces, especially those claiming to be comprehensive compilations, are voluminous and cumbersome. Students often dread memorizing them. Others focus excessively on theoretical analysis rather than completeness. Those of average ability cannot grasp the full picture from a single case or syndrome. My book strives for conciseness and clarity, allowing readers to understand immediately upon opening it."
Alas! These must be the refined, useful words of my uncle in his later years, stripping away vanity. Being foolish and ignorant, I cannot fully elucidate the profound intent of his writings. I merely record his diligence in scholarship, his caution in applying medical techniques, and contemporary remarks concerning this book, so that readers may have evidence for verification. While my uncle was alive, his son, Zhiben, was studying for the imperial examinations, and my uncle never taught him medicine. After my uncle passed away, seekers of medical help claimed there should be extraordinary news (implying inheritance of skill), and they continued to arrive in succession. Reluctantly, I followed the established methods in this book to treat them, and the results were invariably effective. Therefore, my diligence in this printing project goes beyond merely preserving my uncle's handwritten legacy.
Written respectfully by nephew Zhiben, two days before Duanwu Festival, in the year Xinhai (1851) of the Xianfeng era.
