蟹爪（一升） 阿胶（三两） 甘草（二两）
妇人脉阴阳俱盛，名曰双躯，若少阴微紧者，血即凝浊，经养不周，胎却偏夭，其一独
死，其一独生，不去其死，害母失胎，宜此方主之。蟹爪能破胞而堕胎，以其禀锋利之质故
耳，非妊娠所宜也。是方也，盖用蟹爪攻其死，阿胶安其生，甘草平其毒也。或问蟹爪之毒
手，保其不伤彼生者乎？余曰∶无死者则伤生，有死者则毒以类从，惟攻其死，不犯其生。
此《大易》方以类聚，物以群分，水流湿，火就燥之义也。
人参（二两）
水一升，煎半升温服。
产后血晕，不省人事者，此方主之。
血晕者，下血过多而眩晕也。不省人事者，气血大脱而神不用也。故用人参甘温益元之
品以主之。此药可以固气，可以生血，可以益元。身热气急者，加童便一爵。身寒气弱者，
加附子三钱。
凡血晕不省人事者，急治炭火以酽醋沃之，使醋气熏蒸入鼻，则能收敛神气，自然精爽。
红花（一两，炒）
清酒五爵，沃之温服。
胞衣不下，此方主之。
胞衣不下者，气弱而瘀血盈于胞也。故用清酒壮其气，红花败其瘀。
猪肾（一具） 白糯米（三合） 淡豉（五合） 葱白（一升） 人参 当归（各二两）
产后蓐劳者，此方主之。
蓐，产中之名也。产中虚羸喘乏，乍寒乍热，病如疟状，名曰蓐劳。此是虚乏气血不相

类相从，能补系胞之区也。
妇女脉象寸关尺三部及浮沉皆盛大，称为“双躯”（怀有双胞胎），若少阴脉微紧，则血液凝滞浑浊，滋养胎儿的气血不足，导致一个胎儿夭折，另一个存活。若不除去死胎，会伤害母体并危及活胎，适宜用此方主治。蟹爪能破除胞宫并堕胎，是因为它禀赋了锋利坚硬的质地，所以不适合孕妇使用。这个方子，大概是用蟹爪攻逐死胎，阿胶安养活胎，甘草调和药毒。有人问：蟹爪有毒且伤手，怎么保证不伤害那个存活的胎儿呢？我说：没有死胎就会伤害活胎，有了死胎，毒性就会同类相从（只作用于死胎），只攻逐死胎，不侵犯活胎。这符合《易经》中“方以类聚，物以群分，水流湿，火就燥”的道理。
人参（二两）
用水一升，煎煮至半升，温热服用。
所谓血晕，是因为分娩后出血过多而导致的眩晕。所谓神志不清，是因为气血大量脱失而导致神志无法运用。所以用人参这种甘温、补益元气药物来主治。此药可以固护气机，可以生成血液，可以补益元气。如果身体发热、气息急促的，加入童便一杯。如果身体发冷、气虚无力的，加入附子三钱。
凡是产后血晕、神志不清的，紧急烧炭火，将浓醋浇在炭火上，使醋气熏蒸进入鼻腔，就能收敛神气，自然精神清爽。
红花（一两，炒制）
用清酒五杯，浸泡后温热服用。
胎盘（胞衣）不下，用此方主治。
胎盘不下的原因，是气虚且瘀血充满胞宫。所以用清酒壮其气，用红花化解瘀血。
猪肾（一个） 白糯米（三合） 淡豆豉（五合） 葱白（一升） 人参 当归（各二两）
产后蓐劳病，用此方主治。
“蓐”，是指生产期间。生产时身体虚弱羸瘦、气喘乏力，忽冷忽热，症状像疟疾一样，称为“蓐劳”。这是因为气血极度虚弱不能相互顺接，虚所以忽冷，壅滞所以忽热，寒热没有休止时间，症状类似疟疾，但实际上不是疟疾。治疗应当大补气血，使气血顺接，病就好了。所以用人参补气，当归补血，糯米补益胃气，葱和豆豉醒脾开胃。而猪肾，是取“同类相从”之意，能补益系胞的区域（子宫）。
Crab Claws (Shuangzhua, 1 sheng) Donkey-hide Gelatin (Ejiao, 3 liang) Licorice Root (Gancao, 2 liang)
When a woman's pulse is vigorous at both the yin and yang positions (superficial and deep, or upper and lower), it is called "Shuangqu" (indicating twin pregnancy). If the Shaoyin pulse is slightly tight, the blood becomes coagulated and turbid, leading to insufficient nourishment of the fetus. Consequently, one fetus may die prematurely while the other survives. If the dead fetus is not expelled, it will harm the mother and endanger the living fetus; this formula is indicated for such cases. Crab claws can break the uterus and induce abortion because they possess a sharp and hard nature, so they are not suitable for pregnant women. This formula uses crab claws to attack the dead fetus, Ejiao to stabilize the living fetus, and Gancao to moderate toxicity. One might ask: since crab claws are toxic and injurious to the hands, how can we ensure they do not harm the surviving fetus? I reply: without a dead fetus, there would be injury to the living one; with a dead fetus present, the toxicity follows its kind (acting only on the dead tissue). By attacking only the dead, we do not violate the living. This aligns with the principle in the *Book of Changes* (*I Ching*) that "forms gather according to their kinds, things group by their categories; water flows to wetness, fire moves toward dryness."
Ginseng Root (Renshen, 2 liang)
Add one sheng of water, decoct until half remains, and take warm.
This formula is indicated for postpartum blood syncope characterized by loss of consciousness.
"Blood syncope" refers to dizziness caused by excessive bleeding after childbirth. "Loss of consciousness" results from the massive depletion of Qi and Blood, rendering the Shen (Spirit) unable to function. Therefore, Renshen, a sweet and warm herb that tonifies primal Qi, is used as the principal agent. This herb can consolidate Qi, generate Blood, and benefit Yuan Qi. If the patient presents with body heat and rapid breathing, add one cup of child's urine (Tongbian). If the patient presents with cold limbs and weakness, add three qian of Aconite Root (Fuzi).
In cases of postpartum blood syncope with loss of consciousness, urgently burn charcoal and pour strong vinegar onto it. The fumes of the vinegar should be inhaled to astringe the Shen, naturally restoring mental clarity.
Safflower Flower (Honghua, 1 liang, stir-fried)
Soak in five cups of clear wine and take warm.
This formula is indicated for retained placenta (Baoyi bu xia).
Retained placenta occurs due to Qi deficiency and stagnant blood filling the uterus. Therefore, clear wine is used to strengthen Qi, and Honghua is used to resolve stasis.
Pig Kidney (Zhushen, one piece) White Glutinous Rice (Bainuomi, 3 he) Light Fermented Soybeans (Danchi, 5 he) Scallion White (Congbai, 1 sheng) Ginseng Root (Renshen) and Angelica Sinensis Root (Danggui) (each 2 liang)
This formula is indicated for postpartum "Rulao" (childbed consumption).
"Ru" refers to the period of childbirth. Weakness, emaciation, panting, and fatigue during childbirth, accompanied by alternating chills and fever resembling malaria, are termed "Rulao." This condition arises from severe deficiency of Qi and Blood failing to connect smoothly. Deficiency causes alternating chills, while stagnation causes alternating fevers. The chills and fever persist without respite; although symptoms resemble malaria, it is not actually malaria. Treatment requires substantial tonification of Qi and Blood to restore their smooth connection, thereby curing the disease. Thus, Renshen is used to tonify Qi, Danggui to tonify Blood, glutinous rice to benefit the Stomach, and scallions and fermented soybeans to awaken the Spleen. Pig kidney is included based on the principle of "similars attract," as it can tonify the area where the uterus is suspended.
