是书为胎产家便览。既为胎产，必先种子，而后有孕，乃始用安胎。胎前保得十月满足，方用临产。产后
诸样病情，治法用药，以保母子两全，斯作者之心事毕矣。然胎产之书，前哲注刻均行于世。而书多者太繁衍，
简者缺略未备，又有托名翻刻，致失真原，久后流传，以讹传误，难保无危。如薛立斋之良方善矣，而产后发
痉一症用小续命汤，此方为中风而用，其中麻黄、防风、黄芩之类，何堪与产后之人服耶？虽自陈明后续云，
前方与服不已，则转用十全大补。予恐前药过喉，虽有十全，已无补于事矣。再丹溪《胎产秘书》一本，乃周
衡山刻行，善事也。集中云已失作者姓氏，可知借丹溪之名。方中用生化汤，凡一切孕妇，月月可服，此言大
误苍生。盖生化汤为产后去瘀生新之意，其中黑姜、桃仁，岂可施于怀孕妇人？安得不胎热血行，立见其小产
者乎？再以当归、川芎，用少则养血，用多则行血，故产后为必用之药，于理甚明。故吾知非二公之作，真伪
可辨矣。外《达生篇》，临产备用善本，为产家之必要。惜乎胎前产后，俱未备载，得一缺二。今吾书于《达
生》并胎产前后方药齐备，将峻险之药削除，取乎稳当，不致误事，用治胎产，无余蕴矣。然病有变化莫测，
而运用之妙，存乎其人临症消息增减可矣。
这本书是产科医生的便览。既然涉及胎产，必须先有种子（受孕），然后才能怀孕，之后才开始使用安胎的方法。保胎使得十月怀胎足月，才进入临产阶段。产后各种病情的治疗方法和用药，以保全母亲和婴儿双方为目的，这样作者的心事就完成了。然而关于胎产的书籍，前代哲人的注释刻本都在世间流行。但书多的过于繁杂，书少的又简略而不完备，又有借名翻刻的，导致失去原本的真意，长久流传下去，以讹传讹，难以保证没有危险。比如薛立斋的《良方》很好，但是其中治疗产后发痉这一病症使用了小续命汤，这个方子是用于中风的，其中的麻黄、防风、黄芩等药，怎么能让产后的人服用呢？虽然他在后面说明如果前面的药服了无效，则转而使用十全大补汤。我担心前面的药已经入口，即使后来用十全大补汤，也已经无济于事了。再如丹溪的《胎产秘书》一本，是周衡山刻印发行的，这是好事。书中说已经失去了作者的姓氏，可知是借用丹溪的名号。方中使用了生化汤，说凡是所有孕妇，每个月都可以服用，这种说法对百姓危害极大。因为生化汤的本意是产后去瘀生新，其中的黑姜、桃仁，怎么能施加给怀孕的妇人呢？难道不会导致胎热血行，立即出现小产的情况吗？再以当归、川芎为例，用得少则是养血，用得多则是行血，所以产后是必用的药物，道理非常明白。因此我知道这不是两位公子的作品，真伪可以辨别了。另外《达生篇》，是临产备用的善本，为产妇所必需。可惜胎前和产后，都没有完备记载，得到一却缺少二。如今我的书在《达生篇》的基础上，并将胎产前后的方药都齐备，将峻烈危险的药剔除，选取稳妥得当的，不至于误事，用于治疗胎产，就没有什么遗漏了。然而病情变化莫测，运用的妙处，在于医生根据临症情况斟酌增减即可。
This book serves as a handy reference for obstetricians. Since it concerns pregnancy and childbirth, one must first achieve conception (seed), then become pregnant, and only thereafter employ methods to secure the fetus. By preserving the pregnancy until the full ten months are completed, one then proceeds to the stage of labor. The treatment methods and medications for various postpartum conditions aim to ensure the safety of both mother and child, thereby fulfilling the author's intent. However, books on pregnancy and childbirth annotated and printed by past scholars are widely circulated in the world. Those that are voluminous are overly elaborate, while those that are concise lack completeness. Furthermore, forged reprints bearing false names have led to a loss of the original truth. Over time, these errors propagate, making it difficult to avoid potential dangers. For instance, Xue Lizhai’s *Liangfang* is excellent, yet he used Xiao Xuming Tang (Minor Continuation Life Decoction) to treat postpartum convulsions. This formula is intended for wind-stroke; how can herbs such as Ephedrae Herba (Mahuang, 麻黄), Saposhnikoviae Radix (Fangfeng, 防风), and Scutellariae Radix (Huangqin, 黄芩) be administered to postpartum women? Although he later stated that if the previous prescription failed, one should switch to Shiquan Dabu Tang (Perfect Ten Tonifying Decoction), I fear that once the former medicine has passed the throat, even the latter will be of no avail. Similarly, Danxi’s *Taichan Mishu* (Secrets of Pregnancy and Childbirth) was printed by Zhou Hengshan, which is a good deed. The text notes that the author's name is lost, indicating it borrows Danxi’s name. It claims that Shenghua Tang (Life Generation Decoction) can be taken monthly by all pregnant women, a statement that causes great harm to the people. Shenghua Tang is intended for postpartum blood stasis removal and new blood generation; how can Heijiang (Black Ginger, 黑姜) and Persicae Semen (Taoren, 桃仁) be applied to pregnant women? Would this not cause fetal heat and erratic blood circulation, leading immediately to miscarriage? Regarding Angelicae Sinensis Radix (Danggui, 当归) and Chuanxiong Rhizoma (Chuanxiong, 川芎), small doses nourish blood, while large doses promote blood circulation; thus, they are essential medicines postpartum, which is logically clear. Therefore, I know these are not works by these two masters, and their authenticity can be discerned. Additionally, *Dasheng Pian* (Chapter on Natural Birth) is an excellent reference for labor preparation, essential for parturients. Unfortunately, it lacks comprehensive coverage of both antepartum and postpartum stages, obtaining one but missing the other. My book, alongside *Dasheng Pian*, provides complete formulas and medications for both antepartum and postpartum periods. It eliminates harsh and dangerous drugs, selecting only safe and appropriate ones to prevent errors, leaving no gaps in the treatment of pregnancy and childbirth. However, diseases change unpredictably, and the subtlety of application lies in the practitioner’s ability to adjust prescriptions based on clinical presentation.
