[Tai Ping Hui Min He Ji Ju Fang] Duoming Dan: Treats the condition where blood enters the placenta, causing it to swell with blood and preventing expulsion.
Fuzi (Prepared Aconiti Lateralis Radix, half tael) Mudanpi (Moutan Cortex, one tael) Ganqi (Dried Resin of Toxicodendron, one fen, crushed, stir-fried until smoke ceases)
The above ingredients are ground into fine powder. Using one sheng of strong vinegar and one tael of Dahuang powder, boil into a paste, mix with the medicine to form pills the size of paulownia seeds. Swallow five to seven pills with warm wine at any time. This drug expels blood stasis from the uterus; once the blood disperses and swelling subsides, the placenta will naturally descend.
Huarishi San: Treats postpartum breathlessness approaching cessation. The cause is incomplete expulsion of lochia and blood stasis, leading to blood confusion and fainting, evil blood rushing to the heart, fetal death in utero, or retained placenta leading to death. As long as the patient's heart area remains warm, immediately administer one qian of powder mixed with child's urine to expel evil blood resembling pig liver. Thereafter, the patient will never suffer from blood wind or blood qi disorders. If blood stasis exists above the diaphragm, it transforms into yellow fluid, which is expelled via vomiting or urination.
(See section on "Traumatic Injuries".)
Heilong Wan: Treats retained placenta with miraculous efficacy. (See section on "Postpartum Failure of Blood Expulsion".)
Heishen San: Treats sluggish lochia discharge and retained placenta. (See section on "General Postpartum Formulas".)
Niuxi Tang: Treats retained placenta, characterized by hard and distended umbilical/abdominal region, severe pain that can be fatal. After taking this medicine, the placenta rots and descends, and dead fetuses are also expelled.
Niuxi Quma (each four taels) Danggui (three taels) Tongcao (six taels) Huashi (eight taels) Kuiziren (five taels)
The above ingredients are chopped. Boil in nine sheng of water until three sheng remain, divide into three doses. If the placenta does not descend and the abdomen becomes full, it is fatal. Investigating the source, all cases stem from blood rushing to the heart due to the retained placenta, preventing expulsion. Taking this medicine causes the placenta to rot and exit.
Another method for retained placenta: Niuxi one tael, Kuiziren one he. Boil in one sheng of water until half a sheng remains, strain, and divide into two doses.
[Bei Ji Qian Jin Yao Fang] Beiji Dan: Treats postpartum evil blood rushing to the heart, retained placenta, and abdominal blood masses.
Grind one tael of Jinwen Dahuang into fine powder. Use half a sheng of strong vinegar, boil together into a paste, and form pills the size of paulownia seeds. The patient dissolves five to seven pills in seven-tenths of a cup of vinegar and takes them. Within a short time, blood descends and recovery occurs.
[Fu Ren Da Quan Liang Fang] For retained placenta, fetal death in utero, blood rushing upward causing faintness, sudden heavy bleeding, or dried placenta preventing delivery, primarily use Banxia Tang.
(See previous section on "Inducing Labor".)
Xiatai Wan
Banxia Bailian (each half tael)
Grind into fine powder and form pills the size of paulownia seeds. Take thirty pills after meals with Banxia Tang, gradually increasing to fifty pills. If ineffective, use broader-acting medicines, primarily Yubai Pi San; if still ineffective, use Dasheng San; for those with chronic heat, Renshen Jingjie San is suitable.
[Tai Ping Hui Min He Ji Ju Fang] To treat retained placenta, only Huarishi San is most critical. If living in rural areas far from pharmacies and lacking this medicine in haste, here is a wonderful method from Mr. Hu. If the placenta fails to descend after birth, and after some time blood flows into the uterus, causing swelling that rushes upward to the chest and heart, resulting in panting, urgency, and pain, it leads to critical danger. In such cases, immediately cut the umbilical cord, tie it securely with a small object, then sever it completely, preventing fetal blood from flowing back into the uterus. Consequently, 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. To treat retained placenta, stir-fry shed snake skin into fine powder and take two qian with wine. Rushing Holy Paste (see "Antenatal Induction", i.e., Ricinus communis method). If the placenta does not descend and the abdomen swells, it is fatal. Take one he of black beans, roast until cooked, add one cup of vinegar, boil, remove beans, and divide into three doses. For retained placenta, take one cun of yellow earth from the hearth, grind finely, mix with vinegar, apply to the navel, then decoct and drink three to four he of Gancao Tang to facilitate expulsion.
[Shan Ju Fang] Retained placenta: Administer one cup of the water used for washing the newborn for the first time to the mother, without her knowledge.
[Zhen Jiu Ji Cheng] Retained placenta: Needle Sanyinjiao (SP6), Zhongji (CV3) using reducing method.
[Biao You Fu] Another method: Zhaohai (KI6), Neiguan (PC6).
[Jia Yi Jing) Difficult childbirth in women, specifically when the placenta does not descend, Kunlun (BL60) is indicated.
