若血渗胞中，停蓄既久，而为胀为痛，或喘或急，则非逐血破血不可也。宜速用夺命丹，或用失笑散，以

夺命丹（见鬼胎）
失笑散（见经期腹痛）
一方∶用蓖麻子仁一两，研烂，贴母右足心，衣下速洗去，缓则肠亦出。若肠不收，即以此膏涂脑顶，则
肠自入。
一方∶用红花一两，酒煮浓汁服。

胞衣（胎盘）不能排出，有一种情况是因为气血疲弱，无法推动传送，导致停滞搁置而排不出。其症状表现为只有无力感而没有其他疼痛和胀满感，治疗应当补气助血，适宜迅速使用决津煎，或者滑胎煎、保生无忧散、局方黑神散等方剂来主治。
另一种情况是因为恶露（产后余血浊液）流入胞宫（子宫）中，造成胀滞而无法排出。因为胎儿既然已经脱离，胞带必然下坠，所以胞宫在腹中的形状像一片仰着的叶子，仰着的一面就会盛聚血水，从而胀满阻碍难以排出。只有经验丰富的稳婆大多能识别这种情况，只需用手指顶住胞底，以使血液散开，或者用手指探摸上口，攀开一角，使恶露倾泻而出，那么腹部空虚后胞衣自然就会脱落。
决津煎（参见经期腹痛章节）
滑胎煎（参见滑胎章节）
保生无忧散（参见滑胎章节）
《局方》黑神散（参见《妇人规古方》），又名乌金散。《灵苑方》中称为肉桂散。用于治疗产后恶露不尽，胎衣不下，血气攻心，腹痛不止，以及治疗脾肾阴虚，血不守舍，吐血、衄血等症状。
黑豆（二两，炒制） 当归（去芦头，酒洗） 熟地黄 蒲黄 白芍 甘草（炙烤） 干姜（炮制） 肉桂（各一两）
以上药物研为细末，每次服用二钱，用童便（健康儿童的尿液）、酒各一半，调和服用。《良方》中的黑神散含有半两炮附子，没有蒲黄。
又一种方法：用这位产妇的头发搅入其喉中，使其产生呕吐反应，这样气机上升血液散开，胞衣变软自然也会脱落。凡是胎胞不出的，大多会导致死亡，传授这种方法，非常有效。
如果血液渗入胞中，停蓄时间既久，从而形成胀满和疼痛，或者出现气喘或急促的症状，那就非用逐血破血的药物不可了。适宜迅速使用夺命丹，或者使用失笑散，用热酒调服，使血液散开、胀满消除，胞衣自然落下。如果是气血兼虚的情况，也只有决津煎最为适宜。
一方：使用蓖麻子仁一两，研烂，贴敷于母亲右脚脚心，胞衣一旦落下立即洗去，如果动作迟缓则肠子也会脱出。如果肠子不收纳，就用此膏涂抹头顶，肠子自然就会回纳。
一方：使用红花一两，用酒煮成浓汁服用。
一方：使用皂角烧成粉末，每次服用一钱，用温酒调服。
The placenta fails to be expelled. One scenario is due to deficiency and weakness of Qi and Blood, which cannot transport it, causing it to stagnate and remain inside. The symptoms present only as a lack of strength without other pain or distension. Treatment should tonify Qi and assist Blood; it is advisable to promptly use Juejin Decoction (Juejin Jian), or Shuaitai Decoction (Shuaitai Jian), Baosheng Wuyou Powder (Baosheng Wuyou San), Ju Fang Heishen San (Black Spirit Powder from the Bureau Formulas), and similar formulas.
Another scenario involves lochia (postpartum residual blood and turbid fluids) flowing into the uterus, causing distension and stagnation that prevents expulsion. Since the fetus has already detached, the umbilical cord must descend; consequently, the uterus within the abdomen assumes a shape like an inverted leaf. The upward-facing side collects blood and fluid, leading to distension that hinders expulsion. Experienced midwives often recognize this condition. They can use a finger to press against the fundus of the uterus to disperse the blood, or insert a finger to explore the upper opening and pull open one corner, allowing the lochia to drain. Once the abdominal cavity is emptied, the placenta will naturally fall out.
Juejin Decoction (See section on Abdominal Pain during Menstruation)
Shuaitai Decoction (See section on Spontaneous Abortion)
Baosheng Wuyou Powder (See section on Spontaneous Abortion)
Ju Fang Heishen San (Black Spirit Powder from the Bureau Formulas) (See "Ancient Formulas in Furen Gui"), also known as Wu Jin San (Black Gold Powder). In Ling Yuan Fang, it is called Rou Gui San (Cinnamon Twig Powder). It treats postpartum incomplete lochia, retained placenta, Blood and Qi attacking the Heart, unceasing abdominal pain, as well as Spleen and Kidney Yin deficiency with Blood failing to reside in its vessel, hematemesis, and epistaxis.
Hei Dou (Black Bean, two liang, stir-fried) Dang Gui (Angelicae Sinensis Radix, remove radicle, wash with wine) Shu Di Huang (Prepared Rehmanniae Radix) Pu Huang (Typhae Pollen) Bai Shao (Paeoniae Radix Alba) Gan Cao (Licorice Root, honey-fried) Gan Jiang (Dried Zingiberis Rhizoma, processed) Rou Gui (Cinnamomi Cortex, each one liang)
Grind the above into powder. Take two qian per dose, mixed with half child's urine and half wine. Heishen San in Liang Fang contains half a liang of Pao Fu Zi (Processed Aconiti Lateralis Radix) and lacks Pu Huang.
Another method: Insert the parturient woman's hair into her throat to induce vomiting. This causes Qi to ascend and Blood to disperse, softening the uterus so the placenta falls out naturally. Cases of retained placenta often result in death; this method is very effective.
If blood seeps into the uterus and stagnates for a long time, causing distension and pain, or even panting or urgency, then drugs that purge and break Blood are indispensable. Promptly use Duoming Dan (Life-Extending Pill) or Shixiao San (Laughing-Out Powder), taken with hot wine, to disperse Blood and reduce distension, after which the placenta will naturally pass. If there is concurrent deficiency of Qi and Blood, Juejin Decoction is best.
Duoming Dan (See section on Ghost Pregnancy)
Shixiao San (See section on Abdominal Pain during Menstruation)
One prescription: Use one liang of Bi Ma Zi Ren (Ricini Semen kernel), grind it into a paste, and apply it to the sole of the mother's right foot. Wash it off immediately after the placenta is delivered; if delayed, the intestine may prolapse. If the intestine does not retract, apply this paste to the vertex of the head, and the intestine will naturally return.
One prescription: Use one liang of Hong Hua (Carthami Flos), boil in wine to make a concentrated decoction and drink.
One prescription: Heat the sole of the parturient woman's shoe until hot and moxa-like compress the upper and lower abdomen; the placenta will be expelled.
One prescription: Burn Zao Jiao (Gleditsiae Fructus Spinulus) to ash, take one qian per dose, mixed with warm wine.
