嘉庆癸亥立春后一日修园陈念祖题
古代的长官，与百姓亲近。百姓饥饿，就为他们提供食物；寒冷，就为他们提供衣物；遭遇水灾、旱灾、疾病和瘟疫，就为他们提供医药并进行调理。因此能够政绩显著，仁德之名远播。长乐人陈修园（陈念祖）孝廉，精通黄帝内经与岐伯的医术，在“三辅”地区担任县令时，恰逢大水泛滥，奉命前往恒山勘察灾情。他拿出自己的药方，试用后往往见效。后来遭遇父母丧事回乡守制，在守孝读礼的闲暇之余，于是刊印了《时方歌括》和《时方妙用》两本书。
所谓“上医医国”，前人如狄怀英、陆敬舆等贤能之士，在家居住时，通常汇集验证有效的药方来自我娱乐，同时也用来救治世人。《物理论》说：医生，不是仁爱之人不可托付性命；不是聪明通达之人不可委任职责；不是廉洁淳良之人不可信任。陈修园即将推广他的医术以深入探究百姓的疾苦，希望追随古代循吏（奉职守法的好官）的脚步，难道仅仅是凭借医术来售卖牟利吗？
嘉庆癸亥年冬至日，赵在田作序。
医生分为三类：贯通《灵枢》、《素问》以及张仲景诸部经典宗旨，药到病除的，称为名医；讲求唐宋以后方书，按证施治，功效多而过失少的，称为时医；掠取前医成果，套袭模棱两可的药方，以此来掩饰自己的过错，迎合世俗而获取名声的，称为市医。医生的差异竟然如此之大。我的朋友陈修园，精通医理，闭门注释经典，以纠正千古沿袭的错误。考虑到当代名医难以遇到，市医又不可与之谈论，唯独对时医中抱有提携后进之心。他在保阳任职期间，公务之余，撰写了《时方歌括》二卷、《时方妙用》四卷，拿出来给我看。我阅读之后，觉得有的篇幅虽长却不繁杂，有的寥寥数语却无遗漏。一字一句，都是古圣贤的心法。顺从时方，就是顺从古法。于是我为其参订圈点，题名为《公余医录》，鼓励刻版印刷，向海内公开。
辛酉年，我在南宫参加科举考试，蒙受恩惠被任命为三辅地区的县令。恰逢夏季大水泛滥，奉命前往恒山勘察灾情，因劳累染病，得了寒厥证，几乎死去。病愈后，自己定下汤药服用两剂便痊愈了。当时恒山东北地区，正遭受温疟的大患，因用药错误而死的人比比皆是。我怜悯他们，于是在公务之余，采集时方一百零八首，编成韵文歌诀，抄写副本，交给医生们按照方法治疗，大多保全了生命。到了第二年，制府熊谦山先生看到后表示认可，说：“你的心意是好的。然而有方子却不审察其用法，就不足以救人，反而可能杀人。你应该阐明方义并加以推广。”恰逢我遭遇母亲去世的丧事，未能实现。今年在籍贯守孝读礼，谨遵先生济世救人的意愿，续成四卷。诗病原于一百零八首之中，并且我阅读《灵枢》、《素问》，尊崇张仲景，向来有对经方的注释，但应和者寥寥无几。偶然将时方出版，纸张一时昂贵（指畅销），这是投合时好。喜好在此，何不以此引导众人？时方固然不如经方完备，但如果用古法去施行，就与经方互为表里，这也在于运用的精妙罢了。因此题名为《时方妙用》。
嘉庆癸亥年立春后一日，修园陈念祖题。
Ancient magistrates were close to the people. When they were hungry, they provided food; when cold, clothing; in cases of floods, droughts, diseases, and epidemics, they provided medical treatment and regulated care. Thus, they could achieve outstanding merits and have their reputation for benevolence spread far. Chen Xiuyuan (Chen Nianzu), a *xiaolian* (recommended talent) from Changle, was proficient in the arts of Huangdi (Yellow Emperor) and Qibo. While serving as a magistrate in the "Three Fu" region, a great flood occurred, and he was ordered to inspect the disaster relief efforts at Hengshan. He produced his prescriptions, which proved effective upon trial. Later, after returning home to mourn his parents' deaths, during his leisure time reading ritual texts while observing the mourning period, he published two books: *Shifang Ge Kuo* (Rhymed Mnemonics of Contemporary Prescriptions) and *Shifang Miaoyong* (Subtle Applications of Contemporary Prescriptions).
It is said that "the superior physician treats the state." Former sages such as Di Huaiying and Lu Jingyu, while living at home, typically compiled verified effective prescriptions for their own amusement, but also to save the world. The *Wulun* states: "A physician cannot be entrusted with lives unless they are benevolent and loving; they cannot be appointed unless they are intelligent and perceptive; they cannot be trusted unless they are incorruptible, pure, and virtuous." Chen Xiuyuan is about to expand his path to deeply investigate the afflictions of the people, hoping to follow in the footsteps of ancient exemplary officials. Would he merely sell his skills for profit?
Preface by Zhao Zaitian on the Winter Solstice of the Guihai Year of Jiaqing.
Physicians can be divided into three categories: those who penetrate the principles of the *Ling Shu*, *Su Wen*, and the classics of Zhang Zhongjing, achieving cures where the medicine reaches the disease, are called Famous Physicians (*Ming Yi*); those who study prescription books from the Tang and Song dynaies onwards, treat according to syndromes, and have more merit than fault, are called Contemporary Physicians (*Shi Yi*); those who plagiarize previous physicians, copy ambiguous formulas to cover up their mistakes, and cater to public opinion to gain fame, are called Market Physicians (*Shi Yi*). The differences among physicians are thus so great. My friend Chen Xiuyuan is well-versed in medical theory. He closed his door to annotate classics, correcting errors inherited over millennia. Considering that Famous Physicians are rare today and Market Physicians are not worth discussing with, he harbors a heart for guiding Contemporary Physicians. While serving in Baoyang, in his spare time from official duties, he wrote two volumes of *Shifang Ge Kuo* and four volumes of *Shifang Miaoyong*, showing them to me. Upon reading them, I found that some passages were lengthy yet not redundant, while others were brief yet comprehensive. Every word and sentence reflects the mind-method of ancient sages. Following contemporary prescriptions is following ancient methods. Therefore, I reviewed and punctuated them, titled them *Gongyu Yilu* (Medical Records from Leisure Time), encouraged their printing, and made them public throughout the land.
In the Xinyou year, I took the imperial examination in Nangong and, by imperial grace, was appointed as a magistrate in the Three Fu region. A summer flood occurred, and I was ordered to inspect the disaster at Hengshan. Due to overwork, I fell ill with Cold Jue Syndrome (*Han Jue Zheng*), nearly dying. After recovering, I prescribed a decoction for myself, taking two doses resulted in a cure. At that time, the northeast of Hengshan was suffering greatly from Warm Malaria (*Wen Nüe*), with many dying due to incorrect medication. Pitying them, I collected 108 contemporary prescriptions during my spare time, arranged them into rhymed mnemonics, copied them, and gave them to doctors to treat according to the methods. Many lives were saved. The following year, Governor Xiong Qianshan saw them and approved, saying, "Your intention is good. However, having prescriptions without understanding their application is insufficient to save people and may even kill them. You should clarify the meaning of the prescriptions and promote them widely." Unfortunately, I encountered my mother's death and did not succeed in doing so. This year, while observing mourning rites at home, respecting Mr. Xiong's wish to benefit the world and save people, I continued and completed four volumes. The origin of these poems lies within the 108 prescriptions. Furthermore, I read the *Ling Shu* and *Su Wen*, revering Zhang Zhongjing, and had previously annotated classical prescriptions (*Jing Fang*), but few responded. Accidentally publishing contemporary prescriptions (*Shi Fang*) led to high demand (paper becoming expensive temporarily), catering to contemporary tastes. Since this is what is liked, why not guide people through this? Contemporary prescriptions certainly do not match Classical prescriptions in completeness, but if practiced with ancient methods, they stand in mutual relationship with Classical prescriptions. It all depends on the subtlety of application. Hence, I titled it *Shifang Miaoyong*.
