妊娠期间出现转胞（胎位压迫膀胱导致排尿困难），小便不通者，服用此汤，通过探吐法数日即可痊愈。所谓“转胞”，并非指子宫扭转，而是因为孕妇中气虚弱，无法托举胎儿，导致胎体下坠压迫膀胱。因此提升其气机，上窍通畅后，下窍自然通利。
白术（二两）、茯苓（七钱半）、陈皮（三两，不经过火炒）、黄芩（夏季一两，春秋季节七钱，冬季五钱）。
在妊娠第七、八个月时服用此方，可使胎气收敛稳固，让人易于分娩。凡是患有难产的人，多由内热灼烧胞液，导致临产时干涩难产；或者是脾气虚弱，不能运化精微物质，导致胞液不足，这也是难产的原因。所以使用白术、茯苓来补益脾土，以培补万物之母（脾胃为后天之本）；使用黄芩清解胎热，泻火以保存胞液。至于陈皮，取其辛散通利之性，能够流动中焦之气，化解肥甘厚味，使胎气不致停滞，胎儿身体不过于肥大。这就是“束胎”的意义。
大腹皮（三钱，用黑豆汁清洗，晒干后入药）、人参、陈皮、紫苏、当归、白芍药、白术（各一钱）、炙甘草（二钱）。
妊娠临近预产期时，服用此方，可使人易于分娩。
《诗经》说：“诞弥厥月，先生如达。”朱熹解释说：“先生，指头生子；达，指小羊。”小羊生产容易且无滞留困难，所以以前的医生将此方命名为“达生”。然而难产的原因，多是气血虚弱，营卫运行涩滞所致。这个方子中，人参、白术、甘草补益其气，当归、芍药补益其血，紫苏、大腹皮、陈皮疏通其滞涩。气血不虚也不滞，那么分娩就会像小羊一样顺利。
《诗经》说：“采采苤莐，薄言采之。”苤莐，就是车前草。朱熹说：采摘它的具体用途不详，但其种子可以治疗难产。我吴昆得到了这一说法，凡遇到妊娠临近预产期，应当在适宜服用的汤剂中加入车前子，每餐服用。

In cases of pregnancy complicated by *Zhuanbao* (retention of urine due to fetal pressure on the bladder) where urination is impossible, taking this decoction and inducing vomiting for several days will lead to recovery. "Zhuanbao" does not refer to a torsion of the uterus; rather, it occurs because the mother's Middle Qi is weak and unable to support the fetus, causing the fetus to descend and compress the bladder. Therefore, by raising the Qi, when the upper orifices become unobstructed, the lower orifices naturally flow freely.

Taking this formula during the seventh and eighth months of pregnancy helps to consolidate the fetal Qi, facilitating easier delivery. Difficult labor often results from internal heat scorching the fluids of the uterus, leading to dryness and difficulty at the time of birth; or it may be due to Spleen Qi deficiency failing to transform and transport essential nutrients, resulting in insufficient uterine fluids, which also causes difficult labor. Thus, Baizhu and Fuling are used to tonify Spleen Earth, nurturing the "Mother of All Things" (the Spleen/Stomach as the source of post-heaven Qi); Huangqin is used to clear fetal heat, draining fire to preserve uterine fluids. Chenpi is included for its pungent and dispersing properties, which promote the movement of Middle Jiao Qi, resolve rich and sweet foods, prevent stagnation of fetal Qi, and ensure the fetus does not become overly large. This embodies the principle of "binding the fetus."

Taking this formula near the end of pregnancy facilitates easy delivery.
The *Classic of Poetry* states: "When the month of childbirth arrives, the firstborn comes forth easily like a lamb." Zhu Xi explained: "Firstborn refers to the first child; 'Da' refers to a young sheep." Lambs give birth easily without obstruction, hence ancient physicians named this formula "Da Sheng" (Facilitating Birth). However, the cause of difficult labor is mostly due to deficiency of Qi and Blood, and stagnation of Ying and Wei circulation. In this formula, Renshen, Baizhu, and Gancao tonify Qi; Danggui and Shaoyao nourish Blood; Zisu, Dafupi, and Chenpi move stagnation. When Qi and Blood are neither deficient nor stagnant, delivery will be as smooth as that of a lamb.
The *Classic of Poetry* states: "Gathering and plucking the plantain." The plantain (*Cheqian*) is identified here as Plantago Seed (Cheqianzi). Zhu Xi noted: "The specific use of gathering it is unclear, but its seeds treat difficult labor." I, Wu Kun, have learned this theory. Whenever encountering pregnancy near term, I add Cheqianzi to appropriate decoctions, taken with each meal.
