疗产后恶血冲心，或胞衣不下，腹中血块等疾。（《备急》同）
上大黄一两为末，以好醋半升熬成膏，以药末搜膏为丸如梧桐子大，温醋汤吞五丸，良
久取下恶物，不可多服。
疗胞衣不下。栝蒌实一个（取子，研令细）
上酒与童子小便各半盏，煎至七分，去滓温服。（如无实，根亦得）
又方∶红花（一两），酒煮浓汁服。
又方∶以鹿角镑屑三分为末，煮葱白汤调下。
凡欲产时，必先脱常所着衣以笼灶，胞衣自下，仍易产，神验。《广济方》云∶取夫单

妇人百病，莫甚于生产。产科之难，临产莫重于催生；既产莫甚于胞衣不下。惟有花蕊
石散一件，最为紧要。如黑神散、琥珀散诸方之类，虽皆有验，然乡居或远于药局，仓卒之
间，无法可施。今采得胡氏《宝庆方》一妙法云∶若产讫胞衣不下，停待稍久，非特产母疲
倦，又且血流入胞中，为血所胀，上冲心胸，喘急疼痛，必致危笃。若有此证，宜急断脐带
以少物系坠，（以物系坠之时，切宜用心。先系，然后截断。不尔则胞上掩心而死），使其子
血脉不潮入胞中，则胞衣自当痿缩而下，纵淹延数日亦不害人。只要产母心怀安泰，终自下
矣，累试有验。不可轻信坐婆，妄用手法，多有因此而亡，深可浩叹。所以胡氏重引，亲见
其说为据。
Treats postpartum evil blood rushing to the heart, or retained placenta (retained placenta), abdominal blood masses, and other ailments. (Same as recorded in *Beiji Qianjin Yaofang*)
Take one liang of Dahuang (Rhubarb Rhizome) ground into powder, boil with half sheng of good vinegar until it forms a paste, mix the powder with the paste to make pills the size of paulownia seeds. Swallow five pills with warm vinegar water. The evil substances will be discharged after a while; do not take excessively.
Treats retained placenta. One Gualuo Shi (Trichosanthes Fruit) (extract the seeds, grind finely).
Take half a zhan of wine and half a zhan of child's urine, decoct until three-tenths remain, remove the dregs, and take warm. (If the fruit is unavailable, the root may be used instead.)
Another prescription: Honghua (Carthamus Flower) one liang, decoct with wine to obtain a concentrated juice and drink.
Another prescription: Lu Jiao (Deer Antler) shaved into fine pieces, three fen, ground into powder, taken with scallion white soup.
Whenever childbirth is imminent, one must first remove the clothes usually worn and cover the stove with them; the placenta will naturally descend, facilitating delivery. This is highly effective. *Guangji Fang* states: Take the husband's single-layer garment and cover the wellhead; the placenta will emerge immediately. (Same as recorded in *Qianjin Fang*, *Jiyan Fang*, *Jiuji Fang*, Cui's prescriptions, and *Duanju Fang*)
Among all diseases affecting women, none is more severe than childbirth. In obstetrics, nothing is more critical during labor than inducing delivery; after delivery, nothing is more dangerous than retained placenta. Among all remedies, Huarui Shi San (Orpiment Powder) is the most crucial. Although formulas such as Heishen San (Black Divine Powder) and Hupo San (Amber Powder) are effective, if one lives in a rural area or far from a pharmacy, no remedy can be applied in an emergency. I have now collected a wonderful method from Hu's *Baoqing Fang*: If the placenta does not descend after delivery, and delay persists, not only will the mother become exhausted, but blood will flow into the uterus, causing distension. The blood will rush upward to the chest and heart, causing panting, urgency, and pain, leading to critical danger. If these symptoms occur, one should immediately cut the umbilical cord and tie a small object to it to hang down. (When tying the object, one must be extremely careful. Tie it first, then cut. Otherwise, the uterus may rise and compress the heart, causing death.) This prevents fetal blood from flowing back into the uterus, so the placenta will naturally shrink and descend. Even if delayed for several days, it will not harm the person. As long as the mother remains calm, the placenta will eventually descend. This has been tested repeatedly with success. Do not readily trust midwives who use manual manipulation; many have died because of this, which is deeply lamentable. Therefore, Hu re-cites this method, relying on personal observation as evidence.
