凡是胞衣（胎盘）不下，都是因为产妇在分娩时用力过猛导致气力耗尽，没有力气排出胞衣；或者因为产程停滞时间过长，外界寒气侵袭导致血脉凝滞不通；又或者因为产前体质虚弱，气血枯竭导致胞衣停留。这三种情况，应立即用大剂量的生化汤煎服，待气血旺盛、腹部调和后，胞衣自然就会下来；也可以加入二钱鹿角灰，或者用益母丸配合生化汤送服；当胞衣不下时，产妇必须保持坐姿守候，不可躺卧。如果剪断脐带，一定要系上一只草鞋在上面。如果在寒冷的月份扶产妇上床，要让人扶着靠坐好，盖上热被子，经常更换暖腹的衣物，使血液调和、腹部温暖，胞衣就会下来。但是胞衣下来后，必须连续服用几帖生化汤，等到腹痛块痛停止后，再服用加参生化汤。又有因为恶露流入胞中，胀满而不能排出的情况。这是因为胎儿出生后，胞衣必然下坠，所以胞衣在腹中，形状像仰着的荷叶，仰着就会积聚血水，导致胀满阻碍难以排出。将婴儿抱定，不要剪断脐带，只让经验丰富、有见识的稳婆，用右手食指和中指顺着脐带向上探入，直到胞口，轻轻向下钩一下，里面的血水流出，胞衣就下来了，这个方法非常简明，应当是处理胞衣不下的第一妙法，比用药多要好得多。药物的力量总不如手法见效快，所以经验丰富、明白事理且有见识的稳婆，是不可缺少的。有的人用产妇自己的头发搅入喉咙，使其呕吐，从而促使胞衣下来，这绝不是好的方法！
用黑豆二三合，洗净，炒至香熟，加入一大碗醋，煎煮五六次沸腾后，去掉豆渣取汁液，分两次服用，胞衣就会下来。这是仙方，虽然是用醋煎煮，却没有酸涩难闻的味道，应该事先准备好，能够应手见效。
益母丸：治疗妇女赤白带下，恶露时下不止，以及治疗产前、产后、经期各种奇特的疼痛，无所不治，所以名叫益母。益母草这一味药，又名茺蔚子，又名野天麻。它的茎秆特征是对节生长叶子，叶子类似火麻叶，四五月间开紫花的是正品，开白花的不算。在五月采集晒干，连根、茎、叶、花、子一起磨成细末，忌用铁器，用炼蜜制成如弹子大小的丸药。每次服用一丸，用童子尿和热酒化开送服，或者用生化汤化开送服。如果没有预先准备益母丸，直接用生益母草捣汁，加入少许蜂蜜服用，效果更大。
又一方：用黑牛粪不拘多少，稍微烘焙保留湿润，用布包裹起来，束在腹部上面，胞衣就会下来。
又一方：用山柰一二片，让产妇含在口中，有水咽下，胞衣自然会脱落。
又一方：无名异三钱，就是漆匠用来煎油的药物。用鸡蛋调匀，再用陈米醋一茶钟煎滚冲服，胞衣会缩小如秤锤般落下，倘若还没下来，不必惊慌。再服一剂，没有不立即下来的。
半夏散：治疗产妇身体肥胖壮盛，痰多，阻滞气道，导致难产及胎死干瘪，或者胎儿已下而胞衣不出。制半夏不拘多少研成细末，用童子尿调服一方寸匕的量，连续服用三次，并用吹鼻取嚏的方法，以激动关窍为妙。
难产奇验方：生半夏、白蔹，等分共同研成细末。凡是遇到妇人难产，或者一两天不生以及横生、倒生并胎衣不下的情况，紧急使用此药末一钱，用无灰酒调服，没有不立刻落地的。
Any case of retained placenta (retained placenta) is due to the mother exhausting her strength during delivery and lacking the power to expel the placenta; or because the labor has been prolonged, allowing external cold qi to invade and cause blood stasis; or again because of weak constitution before delivery, with depleted Qi and Blood causing the placenta to remain. For these three situations, immediately decoct a large dose of Shenghua Tang (Transforming Stasis Decoction) and administer it. Once Qi and Blood are abundant and the abdomen harmonized, the placenta will naturally descend; alternatively, add 2 qian of Lu Jiao Hui (Deer Horn Ash), or take Yi Mu Wan (Motherwort Pill) delivered with Shenghua Tang. When the placenta fails to descend, the parturient must sit upright and wait, not lie down. If the umbilical cord is cut, a straw shoe must be tied to it. In cold months, when assisting the mother onto the bed, support her in a sitting position, cover her with a warm quilt, and frequently change clothes to keep the abdomen warm. With harmonized blood and a warm abdomen, the placenta will descend. However, after descent, she must continue taking several doses of Shenghua Tang. Once the abdominal pain and mass pain cease, then take Jiashen Shenghua Tang (Shenghua Tang with Added Ginseng). There are also cases where lochia flows into the uterus, causing distension that prevents expulsion. This is because after the baby is born, the uterus inevitably descends; thus, inside the abdomen, the uterine cavity resembles an inverted lotus leaf. Being inverted, it accumulates blood and fluid, leading to distension that hinders descent. Hold the infant securely and do not cut the umbilical cord. Only allow an experienced and knowledgeable midwife to insert two fingers of the right hand along the umbilical cord upwards until reaching the cervical os, then gently hook downwards. The accumulated blood will drain out, and the placenta will follow. This method is very simple and should be considered the first excellent method for expelling the placenta, far superior to using numerous medications. Medicinal efficacy never matches the rapid effect of manual techniques; therefore, experienced, sensible, and knowledgeable midwives are indispensable. Some people use the mother's own hair to tickle the throat to induce vomiting, hoping this will expel the placenta; this is by no means a good method!
Take 2-3 he of black beans, wash them clean, stir-fry until fragrant and cooked, add one large bowl of vinegar, boil five or six times until boiling vigorously, remove the beans, collect the juice, and divide into two doses for consumption. The placenta will then descend. This is a celestial prescription; although decocted with vinegar, it lacks any sour or unpleasant taste. It should be prepared in advance to ensure immediate efficacy.
Yi Mu Wan (Motherwort Pill): Treats leukorrhea (red and white discharge) in women, continuous abnormal lochia discharge, as well as various strange pains during pregnancy, postpartum, and menstruation. It treats all such conditions, hence the name "Benefiting Mother." It consists of a single herb: Motherwort (Yi Mu Cao), also known as Chong Wei Zi (Eclipta Seed) or Ye Tian Ma (Wild Gastrodia). Its stem grows leaves at opposite nodes; the leaves resemble those of Hemp (Huo Ma). The authentic variety blooms purple flowers between April and May; those with white flowers are incorrect. Harvest in May, dry in the sun, and grind the roots, stems, leaves, flowers, and seeds together into fine powder. Avoid using iron vessels. Refine honey to form pills the size of marbles. Take one pill per dose, dissolved in child's urine (Tong Bian) and warm wine, or dissolved in Shenghua Tang. If Yi Mu Wan was not prepared in advance, crush fresh Motherwort, extract the juice, mix with a little honey, and consume; the effect is even greater.
Another formula: Use black cow dung, amount unspecified, slightly roasted but kept moist, wrap in cloth, and bind it to the upper abdomen. The placenta will descend.
Another formula: Take 1-2 slices of Kaempferia Galanga (Shan Nai), let the parturient hold it in the mouth, swallow with saliva, and the placenta will naturally fall.
Another formula: Use 3 qian of Wuming Yi (Pyrolusite), which is the mineral used by lacquerers to refine oil. Mix evenly with an egg, then boil with one tea cup of aged rice vinegar and drink while hot. The placenta will shrink like a weight and descend. If it does not descend immediately, do not panic. Take another dose, and it will surely descend promptly.
Banxia San (Pinellia Powder): Treats parturients who are obese and phlegm-heavy, where phlegm obstructs the airway, leading to difficult labor, fetal death with desiccation, or failure of the placenta to descend after the fetus is born. Processed Pinellia Rhizome (Zhi Ban Xia), amount unspecified, ground into fine powder. Administer one cun chi (square inch spoonful) mixed with child's urine. Continue for three doses. Additionally, use nasal insufflation to induce sneezing, which is excellent for opening the orifices.
Miraculous Verified Formula for Difficult Labor: Raw Pinellia Rhizome (Sheng Ban Xia) and Akebia Root (Bai Lian), equal parts, ground together into fine powder. Whenever encountering difficult labor in women, whether lasting one or two days without birth, or malpresentations such as transverse or breech presentation, accompanied by retained placenta, urgently use one qian of this powder, mixed with unadulterated wine. It will invariably result in immediate delivery.
