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.
