法甚效。
胎儿死于腹中，多是因为受惊动得太早，或者触犯禁忌，或者被人抱腰太重，或者频繁探试羊水，导致胞衣先破，血水先流尽，而胎儿因干枯而死。其征象是产妇的嘴唇和舌头都发黑的，母子俱死。如果舌头发黑或胀闷严重的，虽然胎儿已经死了。先用平胃散一两，用酒和水各半煎煮，然后投入朴硝半两，立即服用热化的皮硝，或者用朴硝一两，用童子尿调服也很好。
治验记录：
一位稳婆的女儿勤劳辛苦地负重，怀孕时腹部感觉阴冷沉重下坠，口中气味很秽浊，我推测她的胎儿必定已死，让她查看舌头果然青黑，给她服用约半两朴硝，随即排出秽浊液体而平安无事。
另一位妇人胎死腹中，服用朴硝后排出秽浊液体，肢体倦怠，气息微弱，以四君子汤为主方，佐以四物汤、生姜、肉桂，调理补益而痊愈。
有因为恶露进入胞衣，胀满而不能排出的；有因为元气亏损，而不能送出的。那些恶露流入胞衣中的，腹部胀痛，用夺命丹或失笑散，来消除瘀血，拖延则无法救治。那些元气不能送出的，腹部不胀痛，用保生无忧散，来补固元气。或者用蓖麻子仁一两，细细研磨成膏，涂在母亲右脚心，胞衣下来后立即洗去，拖延则肠子也会脱出，如果肠子不上去，仍然用此膏涂在头顶，则肠子自然收回，益母丸也有效。宝庆方的说法是胎衣未下时，如果想剪断脐带，先以少量物体系住坠着，然后剪断，否则胞衣上掩心脏而死。
治验记录：
某家眷属胞衣不出，胸腹胀痛，手不敢靠近，这是瘀血为患，用热酒送服一剂失笑散，恶露和胎衣随即一起排出。
一位产妇胎衣不出，腹部不胀痛，用手按压疼痛稍缓解，这是气虚而不能送出，用无忧散而排出。前面的病症我询问各位稳婆说，宜服用益母草丸，或者就用产妇的头发入口引起呕吐，胎衣自然排出，不排出的必定死亡。传授上述方法非常有效。
Fetus retained in the uterus (Zisi Fuzhong) is mostly caused by being startled too early, or violating taboos, or being hugged around the waist too heavily, or frequently testing the amniotic fluid, causing the fetal membranes to rupture first and the blood and water to drain out completely, leading to the fetus drying up and dying. The signs are that if both the lips and tongue of the mother turn black, both mother and child die. If the tongue turns black or distension and oppression are severe, although the fetus has already died. First, administer Pingwei San (Calm the Stomach Powder) 1 liang, decocted with half wine and half water, then add Puxiao (Mirabilite) 0.5 liang, and immediately take the hot-melted skin mirabilite, or use 1 liang of mirabilite mixed with urine from a healthy boy, which is also excellent.
Clinical Cases:
A daughter of a midwife worked hard carrying heavy loads; during pregnancy, she felt coldness and heaviness/dragging in the abdomen, and her breath was very foul. I suspected the fetus must be dead, asked her to check her tongue, which was indeed greenish-black. She took about 0.5 liang of Puxiao (Mirabilite), subsequently discharged foul fluids, and recovered safely.
Another woman had a dead fetus; after taking Puxiao (Mirabilite), she discharged foul fluids. Her limbs were fatigued, and her breathing was faint. Using Sijunzi Tang (Four Gentlemen Decoction) as the main formula, assisted by Siwu Tang (Four Substances Decoction), Shengjiang (Fresh Ginger Rhizome), and Rongui (Cinnamon Bark), she recovered through regulation and tonification.
Some cases involve lochia entering the membranes, causing distension preventing expulsion; others involve deficiency of Yuanqi (Primary Qi) preventing expulsion. In cases where lochia flows into the membranes, there is abdominal distension and pain; use Duoming Dan (Life-Restoring Pill) or Shixiao San (Pain-Relieving Powder) to resolve blood stasis; delay will result in untreatable conditions. In cases where Yuanqi (Primary Qi) cannot expel, there is no abdominal distension or pain; use Baosheng Wuyou San (Protect Life and Ensure Safety Powder) to tonify and secure Yuanqi (Primary Qi). Alternatively, use 1 liang of Ricini Semen (Bibingzi/Ricinus communis seed flesh), finely ground into a paste, applied to the sole of the mother's right foot. Once the placenta is expelled, wash it off immediately; if delayed, the intestines may prolapse. If the intestines do not retract, apply this paste to the vertex of the head, and the intestines will naturally return. Yimu Wan (Motherwort Pill) is also effective. According to the Baoqing method, when the placenta has not yet been expelled, if one wishes to cut the umbilical cord, first tie a small weight to it, then cut it; otherwise, the uterus may retract upwards covering the heart, leading to death.
Clinical Cases:
The wife of a family member had an unexpelled placenta, with chest and abdominal distension and pain, unable to bear touch. This was due to blood stasis. One dose of Shixiao San (Pain-Relieving Powder) was administered with hot wine, and the lochia and placenta were expelled together.
A postpartum woman had an unexpelled placenta, without abdominal distension or pain, but slight relief of pain upon pressure. This was due to Qi deficiency failing to expel it. Wuyou San (Safety Powder) was used for expulsion. Regarding previous symptoms, I consulted midwives who suggested taking Yimucao Wan (Motherwort Pill), or inducing vomiting by placing the parturient's hair in her mouth, which would cause the placenta to expel naturally; failure to expel leads to death. The aforementioned methods proved very effective.
