一、凡妇人怀孕，惟赖气血养护，时常行动则气血周流，胞胎活动，骨缝关节处亦常松动，临产自
易。如久坐久卧，气不营运，血不流顺，胎亦沉滞而不活动，骨节亦紧而不松泛，故令难产。常见田
野劳苦妇女，忽然途中腹痛，立便生产可知。
一、胎之所以养，赖母之所嗜，因子母之气，呼吸相通，是以胎之肥瘦，在母之素日奉养浓薄何
如耳。如母平时恣食浓味，不知节减，多致胎肥衣浓而难产。常见糟糠之妇，容易生产可知。
一、古者，妇人有孕即居侧室，不共夫寝，恐欲火动中，气血沸腾而消耗。胎系胞中，全资气血育
养，一有所犯，五月以前，故多胎漏小产；五月以后，每致胞浓难生。更且漏泄胎元，子多不寿，疮痘疹
毒，子疾难医。不然，但看马牛犬豕，胎胎易，个个存，何也？盖因马牛犬豕一受孕后，绝不交合，而
人受孕不能禁绝，矧有纵欲无度者乎。人畜不同，禀生则一，可不慎欤？
一、凡新妇初产，神气怯弱，未曾经惯，切不可与言产变之事。恐怀忧惧，心悬气馁，原本易生，
反成难产矣。况子户未舒，更恐护痛，腰屈不伸，展转倾侧，撩乱多时，精神困乏，儿不得出。即中年妇
人生育既多，气血虚少，均虑产时艰难。气血虚少，精神困乏，俱宜独参汤催生甚妙。余则参看临产
须知，并催生及交骨不开门。
一、孕妇有素常虚弱，饮食减少，至临产乏力。或因儿未欲出用力太早，及
儿欲出母已无力。令儿停住，产户干涩，产亦艰难，用催生万全汤最妙，或独参汤催生亦妙。有等妇
人临产不能饮食，用人参三二钱煎汤服之，大助精力，甚于肉食百倍。
一、凡是妇人怀孕，全靠气血来养护。经常活动则气血周流全身，胞胎随之活动，骨骼关节处也常处于松动状态，分娩时自然容易。如果久坐或久卧，气机不能运行，血液不能流畅，胎儿也会沉滞而不活动，骨节也会紧缩而不松弛，从而导致难产。常见田野间劳苦的妇女，忽然在路上腹痛，立刻就能生产，由此可知。
二、胎儿之所以得到滋养，依赖于母亲平时的饮食喜好。因为母子之气呼吸相通，所以胎儿的肥瘦，取决于母亲平日供养的浓厚还是淡薄。如果母亲平时放纵口腹之欲，多吃浓味厚腻的食物，不知节制减少，多会导致胎儿过肥、胎衣过厚而难产。常见吃糟糠粗食的妇女，容易生产，由此可知。
三、古时候，妇人怀孕后就居住在侧室，不与丈夫同寝，担心情欲之火在心中萌动，导致气血沸腾而消耗。胎儿系于胞宫之中，完全依靠气血来养育。一旦触犯禁忌，五月以前，大多导致胎漏或小产；五月以后，往往导致胞宫厚实（指胎盘或羊水异常等）难以分娩。更严重的是漏泄胎元，子女大多寿命不长，易患疮痘疹毒等疾病，且子疾难医。否则，只看马、牛、狗、猪，它们的胎儿个个容易出生，个个都能存活，为什么呢？大概因为马牛犬豕一旦受孕后，绝不交合，而人受孕后不能禁绝性欲，更何况有纵欲无度的人呢？人与牲畜在禀赋生命上是一样的，怎能不谨慎呢？
四、凡是新婚妇女初次生产，神气怯弱，没有经历过，切不可与她谈论分娩变故的事情。恐怕引起忧虑恐惧，导致心悬气馁，原本容易生产的，反而变成难产了。况且子户（子宫）尚未舒展，更可能因为护痛（保护疼痛），腰部弯曲不能伸直，辗转反侧，慌乱许久，精神困乏，胎儿不得出。即使是中年妇女生育次数多，气血虚少，也都担心分娩艰难。气血虚少，精神困乏，都适宜用独参汤催生，效果很好。其余情况可参考《临产须知》，以及关于催生和交骨不开的门类。
五、孕妇如果有素日虚弱，饮食减少，到了临产时乏力。或者因为胎儿还未到该出的时候就过早用力，以及胎儿将要出来时母亲已无力气。导致胎儿停住，产道干涩，分娩也艰难，使用催生万全汤最好，或者用独参汤催生也很好。有些妇女临产时不能进食，用人参二三钱煎汤服用，大大帮助精力，胜过肉食百倍。
1. Whenever a woman is pregnant, she relies solely on Qi and Blood for nourishment. Frequent movement ensures the smooth circulation of Qi and Blood throughout the body, causing the fetus to move and the joints and bone fissures to remain loose, making delivery easy when the time comes. Conversely, prolonged sitting or lying down prevents Qi from circulating and Blood from flowing smoothly, causing the fetus to become stagnant and inactive, and the joints to become tight rather than relaxed, thus leading to dystocia (difficult childbirth). This can be observed in laboring women in the fields who suddenly experience abdominal pain while traveling and deliver immediately.
2. The reason the fetus receives nourishment depends on the mother's dietary preferences. Because the Qi of the mother and fetus communicates through respiration, the fatness or thinness of the fetus depends on whether the mother's daily sustenance is rich or plain. If the mother indulges in rich and heavy flavors without restraint, it often results in an overly large fetus and thick placental membranes, leading to dystocia. This is evident in women who consume coarse food, who find childbirth easier.
3. In ancient times, pregnant women would reside in separate quarters and not share a bed with their husbands, fearing that sexual desire might stir within, causing Qi and Blood to boil and deplete. The fetus is suspended in the Bao Zhong (uterus) and relies entirely on Qi and Blood for nourishment. Violating these precautions before the fifth month often leads to Tai Lou (fetal leakage) or spontaneous abortion; after the fifth month, it often results in a "thick womb" condition making delivery difficult. Furthermore, leaking the Tai Yuan (fetal origin) may result in offspring with short lifespans or susceptibility to sores, pox, and rashes, which are difficult to treat. Otherwise, observe horses, cattle, dogs, and pigs: their litters are born easily and survive well. Why? Because once pregnant, these animals do not mate, whereas humans cannot abstain after conception, let alone those who indulge excessively. Although human and animal life origins are similar, one must be cautious.
4. For newlywed women giving birth for the first time, their Shen Qi (Spirit and Qi) is timid and weak, lacking experience. One must absolutely avoid discussing complications of childbirth with them. Fear of anxiety and dread may cause the Heart to hang and Qi to collapse; what was originally an easy delivery may turn into dystocia. Moreover, if the Zi Hu (uterus/vagina) has not yet expanded, fear of pain may cause the woman to bend her waist without straightening, tossing and turning in confusion for a long time, exhausting her Spirit and Qi, preventing the child from being born. Even middle-aged women who have given birth many times may suffer from deficient Qi and Blood, worrying about difficult labor. For cases of deficient Qi and Blood and exhausted Spirit, Dushen Tang (Ginseng Decoction) is excellent for promoting delivery. For other situations, refer to "Notes on Labor" and sections on promoting delivery and treating unopened Jiao Gu (pubic symphysis).
5. Pregnant women who are constitutionally weak and have reduced appetite may lack strength at term. This may be due to pushing too early before the fetus is ready to descend, or the mother having no strength left when the fetus is ready to exit. This causes the fetus to stall and the birth canal to become dry, making delivery difficult. Cui Sheng Wan Quan Tang (Delivery Ten-Thousand-Complete Decoction) is best used here, or Dushen Tang (Ginseng Decoction) is also effective. Some women cannot eat during labor; administering 3–2 qian of Ginseng decocted in water greatly boosts energy, surpassing the benefit of meat by hundreds of times.
