《卫生易简方》凡十二卷，附录一卷，礼部尚书胡公源洁纂集之书也。公初以都给事中，
后改礼部侍郎，将使命于四方者，几廿年。名山胜境，靡不游历；足迹所至，过于司马子长
远矣！咨询之次，间得医方便于愈疾者，类次为书，名之曰∶易简。盖简则措语不烦，易则
药无隐僻。语不烦，则人皆可晓；药无隐，则急或可求。视他方之博而寡要者，大有径庭。
既成编，表进于朝，上悦之，什袭缄HT ，藏之秘府。公退以其副镂梓传诸远迩。呜呼，
公之用心可谓勤矣！其惠利及人可谓浓矣！余又闻公之近世以医业相承，尝居善药，以应人
之求。贫困者不责其直，赖以全活啻千百，故公食其报于明盛之时。今公是书之行，所赖全
活者日益众，子孙食报于后，盖可必也。虽然公以弘博雅重之量，为圣天子心膂股肱，出谋
虑、赞可否，以成无为之治。俾亿兆黎元，咸跻仁寿之域，要皆以易简为本，其德泽所被，
又岂是书

《卫生易简方》共十二卷，另附一卷，是由礼部尚书胡源洁公编纂的书籍。胡公起初担任都给事中，后来改任礼部侍郎，奉命出使四方将近二十年。名山大川和优美风景，没有不游历的；他的足迹所到之处，比司马迁还要远！在咨询询问的过程中，偶尔得到一些由治愈疾病的人提供的简便医方，便分类编排成书，命名为“易简”。大概是因为简单所以措辞不繁琐，容易所以药物不偏僻罕见。措辞不繁琐，那么人人都能理解；药物不偏僻，那么在紧急时刻或许可以求得。与其他那些广博但缺乏要领的医方相比，差别很大。
书编成后，呈表进献给朝廷，皇上很高兴，用多层布包裹并封缄起来，收藏在皇家秘府中。胡公退朝后，将副本刻印流传于远近各地。唉，胡公的用心可以说是勤劳了！他的恩惠利益惠及众人可以说是深厚了！我又听说胡公在近世以医术相传承，曾经储备良药，以应对人们的求药需求。对于贫困者他不索取药费，依靠他保全性命的不止千百人，所以胡公在明朝盛世得到了福报。如今胡公这本书的刊行，所依赖保全性命的人日益增多，子孙后代享受福报，大概是必然的了。虽然如此，胡公凭借宏大渊博、高雅庄重的气量，作为圣明天子的心腹股肱之臣，出谋划策，赞襄政事，以成就无为而治的太平盛世。使得亿万百姓，都进入仁爱和长寿的境界，这都要以“易简”为根本，他的德泽所覆盖的范围，又岂止是这本书呢？

《卫生易简方》，是当今礼部尚书、毗陵胡源洁公所编纂的。胡公在永乐年间，由给事中提拔为礼部侍郎，常常奉命出使四方。凡是山川风物不同的适宜之处，百姓生活习俗不同的风尚，没有不遍览并周知其中原因的。偶尔以医书中记载及时俗所传的医药物品，施舍以救济他人，总是记录并验证考察它们。岁月久了，所得到的经验越来越多，于是又精心广泛采集，区分归类，编辑成书，共十二卷，命名为《卫生易简方》，他的用心也是勤劳了。永乐癸卯年秋天，我随从皇帝巡幸塞外，胡公恰好因事前往皇帝驻跸之地，并且进献这本书。当时正值秋半，天气非常寒冷，皇上召胡公进入帐篷，与他交谈并反复翻阅此书，极加称赞欣赏，直到夜晚取来蜡烛，命令宦官用玺印标记在上面，装入匣子收藏起来，等到退下时已经是二更天了。我私下庆幸胡公受到尊荣待遇的隆重，并且深深欢喜这本书得以遭遇赏识。近年来，胡公不肯独自珍藏，于是下令刻印，以嘉惠四方，他不嫌弃让我在他的书后题字。只有仁人君子在世，没有不用尽他们的心的。当胡公周游天下，勒马咨询之时，用来宣扬皇上的恩德，通达下情，他的仁爱惠及百姓已经很多了！而且尤其想着编纂这部书，以惠及那些遭受疾病伤痛无处安身的人，他的用心是怎样的呢？如今胡公位列六卿之一，以辅佐天子、调理国家元气为己任。又想推广这本书，使天下的人都能够借此解除疾苦，保全生命，他的用心仁爱，周全细致又达到这种程度，这难道不是调理国家元气的一个帮助吗！我对此更加赞赏这本书的际遇，并且知道我太宗皇帝之所以嘉奖胡公，并非偶然，所以写下这些文字放在卷末，以彰显胡公用心的仁爱。凡是得到这本书的人，要以此精读……

*Wei Sheng Yi Jian Fang* (Hygiene and Simplicity Formulas) consists of twelve volumes, with an additional appendix of one volume. It is a book compiled by Hu Yuanjie, the Minister of Rites. Initially serving as Censor-in-Chief (Ji Ge Shi Zhong), he was later transferred to the position of Vice Minister of Rites. For nearly twenty years, he was entrusted with missions to various regions. He traveled to famous mountains and scenic spots without exception; the places his footsteps reached were far beyond those visited by Sima Qian! During his inquiries and consultations, he occasionally obtained convenient medical prescriptions from those who had been cured. He classified and arranged these into a book, naming it "Yi Jian" (Easy and Simple). The rationale is that being simple means the language is not verbose, and being easy means the medicinal materials are not obscure or rare. If the language is not verbose, everyone can understand it; if the medicinal materials are not obscure, they might be obtainable in emergencies. Compared to other medical formularies that are extensive but lack essential points, this book differs greatly.
Once completed, the manuscript was presented to the court. The Emperor was pleased, wrapped it in multiple layers of cloth, sealed it, and stored it in the imperial secret library. After retiring from official duties, the Duke distributed copies for printing and dissemination to distant and nearby areas. Alas, the Duke's diligence in his efforts can be described as remarkable! His benevolence and benefits to humanity can be described as profound! I have also heard that in recent times, the Duke inherited medical practices and maintained a stock of good medicines to meet people's requests. He did not charge the poor for the cost, relying on him to survive numbered in the thousands. Thus, the Duke received his reward during the prosperous times of the Ming Dynasty. Now, with the circulation of this book, the number of people saved relies increasingly on it, and it is certain that his descendants will enjoy the rewards in the future. Nevertheless, endowed with a broad, erudite, elegant, and dignified demeanor, the Duke serves as the trusted minister and pillar of the Sage Emperor, offering counsel and assisting in decision-making to achieve governance through non-action (Wu Wei). This enables the myriad people to reach the realm of benevolence and longevity. All of this is based on the principle of "Yi Jian" (Simplicity). The scope of his virtue and grace extends far beyond what is contained in this book alone.

*Wei Sheng Yi Jian Fang* (Hygiene and Simplicity Formulas) is compiled by Hu Yuanjie, the current Minister of Rites from Piling. During the Yongle era, the Duke was promoted from Censor-in-Chief to Vice Minister of Rites and frequently served as an envoy to various regions. He thoroughly observed and understood the reasons behind the diverse climates and customs of different landscapes and the varying habits of the common people. Occasionally, he would use medicinal items recorded in medical texts or transmitted by popular custom to relieve others' suffering, always recording and verifying their effects. As time passed, his accumulated experience grew, leading him to carefully collect extensively, categorize, and compile them into a book of twelve volumes, named *Wei Sheng Yi Jian Fang*. His dedication was indeed diligent. In the autumn of the Gui Mao year of Yongle, I accompanied the Emperor on a tour outside the Great Wall. The Duke happened to go to the imperial camp on business and presented this book. At that time, it was mid-autumn, and the weather was very cold. The Emperor summoned the Duke into the tent, conversed with him, and repeatedly reviewed the book, praising it highly. Until nightfall, candles were brought, and eunuchs were ordered to mark it with the imperial seal, after which it was boxed and stored. By the time we retired, it was already the second watch of the night. I privately rejoiced at the high honor bestowed upon the Duke and deeply appreciated the fortunate encounter of this book. In recent years, the Duke has refused to keep it secret, ordering it to be printed to benefit all directions. He did not disdain asking me to write a postscript. Only benevolent gentlemen exert their minds in everything they do in the world. When the Duke traveled widely, pausing to inquire, he aimed to propagate the Emperor's virtue and convey the feelings of the people, extending his benevolence to the masses significantly! Moreover, he particularly considered compiling this work to help those suffering from disease and injury who had no place to rest. How profound is his intention! Now, holding a position among the Six Ministers, he assists the Emperor and takes regulating the primordial qi of the state as his duty. He wishes to widely disseminate this book so that people everywhere can alleviate their suffering and preserve their lives. His benevolent and compassionate mind, thorough and meticulous as it is, does this not serve as an aid to regulating the state's vital energy? I hereby further praise the fortune of this book and realize that the reason our Taizong Emperor praised the Duke was not accidental. Therefore, I wrote these words at the end of the volumes to highlight the Duke's benevolent intention. Those who obtain this book should study it carefully...
