天地最伟大的德行在于“生”（创造生命），而胎产这一事项，则是天地将这种生生不息的德行寄托于人，以此来繁衍人口、扩大教化。然而其中常有难产的情况，导致无法救治。这本来是生育之事却变成了致死之事，难道符合天地生生不息的本意吗？这也是因为调养摄护、医疗诊治以及人事安排失去了适宜之道的缘故。
新安汪朴斋先生，是精通岐黄之术（中医）的名家，凡是经他医治的病人，即使濒临死亡也多能救活。大江南北的人们，都推崇他为扁鹊再世。他又出版了自己所著的《产科心法》一书，将其分为四个部分：一是种子（备孕助孕），二是胎前（妊娠期），三是临产（分娩期），四是产后（产褥期）。书中条理清晰，分析细致，提纲挈领，抓住关键。其中根据症状附带的方剂，大多中正平和，删去了峻猛的药物。看他的自序说，这是耗尽了几十年研究的功力，心得与手法相契合的成果，不是那些剽窃方书、拼凑成说的可比。确实如此，这是救世的慈悲之心，也是产科医生的宝贵指南。
我的朋友周芾庭先生在山东得到了这本书，带到京师，朋友们互相抄录，邮寄回故乡。甲子年孟夏（农历四月），李固先生见到后非常喜欢，认为其精要详明，可以补充《产科机要》、《救产全书》、《达生篇》等书籍所未完备之处，应当公之于众，于是率领本宗族的弟侄捐资交给刻书匠人刊印。我想这本书成于乾隆庚子年，当时只有抄本，流传不广，历经二十五年，才得到各位君子刊行，而朴斋先生救世的慈悲之心，才得以广泛传播于天下。从此每家都有这本书，将所有关于调养医疗的方法，清晰地呈现在眼前，融会贯通，固然可以窥探产科的精微奥妙。其次按照症状选取方剂，墨守其说法并使用，也不会走入歧途错误。将会看到子孙有螽斯（多子多福）的喜庆，母亲没有生产损伤的灾难，而天地生生不息的心意，也因此感到欣慰而无憾了。那么作者和刊印者，他们的功劳都是伟大的啊。
嘉庆甲子年仲秋月（农历八月）上浣二日（初一到初十的前两天，即初二），石门蔡德淳作序并书写告示。
The greatest virtue of Heaven and Earth is "Sheng" (the generation of life). The matter of pregnancy and childbirth is where Heaven and Earth entrust this generative virtue to humans, thereby multiplying the population and expanding their influence. However, there are often cases of difficult labor that lead to untimely death. This turns a process of birth into one of killing, which certainly does not align with the original intent of Heaven and Earth's generative nature. This is due to improper care, medical treatment, or human management.
Mr. Wang Puzhai from Xin'an was a renowned master of Qi-Huang (Traditional Chinese Medicine). Even patients on the verge of death could often be saved under his care. People north and south of the Yangtze River praised him as a reincarnation of Bian Que. He further published his work, *Obstetric Heart Method* (*Chanke Xinfa*), dividing it into four categories: Seed Planting (Fertility/Conception), Pre-natal (Pregnancy), Labor (Delivery), and Post-natal (Postpartum). The content is meticulously analyzed and categorized, extracting key principles. The formulas provided according to symptoms are generally balanced and mild, removing harsh and potent ingredients. As stated in his preface, these results were achieved through decades of research, where understanding and application were seamlessly integrated, unlike those who merely plagiarize medical texts or compile existing theories. Indeed, this reflects a compassionate heart for saving lives and serves as a precious raft for obstetricians.
My friend, Mr. Zhou Feiting, obtained this book in Shandong and brought it to the capital, where friends copied it and mailed it back to their hometowns. In the early summer of the Jiazi year, Mr. Li Gu saw it and greatly appreciated it, stating that its precision and clarity could supplement the deficiencies found in books such as *Obstetric Essentials*, *Complete Book for Saving Births*, and *Da Sheng Pian*. He believed it should be made public. Thus, he led his clan members and nephews to donate funds for printing. I note that this book was completed in the Gengzi year of the Qianlong reign; at that time, only manuscript copies existed, and circulation was limited. Twenty-five years later, thanks to the efforts of these gentlemen, it has been printed and distributed. Consequently, Mr. Puzhai’s compassionate intention to save lives can now spread widely across the world. With this book in every household, one can clearly see all methods for care and treatment. By integrating and comprehending them, one can indeed glimpse the profound essence of obstetrics. Furthermore, by selecting formulas based on symptoms and adhering to these teachings, one will avoid errors. It is anticipated that families will enjoy the blessing of abundant offspring (like the locust plant symbolizing fertility), and mothers will suffer no trauma from childbirth. Thus, the generative heart of Heaven and Earth will be satisfied without regret. Therefore, both the author and the publishers have rendered great merit.
