大全云∶妊娠羸瘦，或挟疾病，脏腑虚损，气血枯竭，不能养胎，致胎动而不坚固，若终
不能安者，则可下之，免害妊妇也。
薛氏曰∶前证宜用腰腹背痛门方论主治。其胎果不能安者，方可议下，慎之慎之！

《大全》说：妊娠期间身体消瘦，或者兼夹疾病，导致脏腑虚损，气血枯竭，无法滋养胎儿，致使胎动不安且不坚固。如果最终无法安胎，则可以采用下胎的方法，以免危害孕妇的生命。
薛己（薛氏）说：上述证候应当参考“腰腹背痛门”中的方论进行主治。只有当胎儿确实无法保住时，才可以讨论使用下胎法，务必谨慎！
大中丞许少微公在担任金坛县令时，其夫人出现胎漏（妊娠期阴道少量出血），经过治疗未能止住。当时正值上级考核期限临近，许公想要顺应病势让胎儿排出，便来征求我的意见。我只让他服用佛手散，认为如果能安胎就安胎，如果不能安胎就让它排出，顺其自然罢了。服药几次后，许公忧虑怀疑，犹豫不决。一位妇科医生检查方剂后进献建议，于是使用牛膝一两，用酒煎服。该医生说：“牛膝本来就是补益下部的药物，用它有什么害处？”许公便相信并让夫人服下，结果胎儿果然排出。我当时正逢母亲去世的丧事，来不及知道这件事。等我得知消息急忙赶到时，只听到满屋子都是肉桂和麝香的气味，原来是因为胞衣（胎盘）未下，女医又进献了香桂散。于是血液突然大量涌出，像大河决堤一样，再也无法止住。紧急煎煮独参汤，药还没熬好，夫人就去世了。许公悲伤稍定之后，前来向我致谢，并且询问我说：“牛膝是补药却能使胎儿流产，这是为什么呢？”我回答说：“生用的牛膝具有宣通发散的作用，熟用的才具有补益作用（关于‘生宣热补’的说法，看似有理实则错误，请深思）。所以破血与填精的作用，就像箭锋相对一样截然相反，难道只有牛膝是这样吗？鹿角也能堕胎破血，但如果煎制成白胶（阿胶类制品），就能安胎止血。因为熟悉它的熟用功效而误信其生用功效，这就是所谓的粗工（医术低劣的医生）。许公叹息悔恨不已，所以我特意记录此事，作为世人的警戒。
桂心散：治疗妊娠因病导致胎不能安的情况，可以使用此方下胎。
药材：桂心、栝蒌、牛膝、瞿麦（各五分），当归（一钱）。
制法：以上药材切碎，用水煎服。
另一方：单用牛膝一两，酒一盅，煎至七分，分两次服用。
千金神造汤：妇人脉象寸关尺阴阳两部都盛大，称为双躯（怀双胞胎）。如果少阴脉微紧，血液就会凝浊，经血滋养不周，胎儿就会一个夭折，另一个独自存活。如果不去除死胎，会危害母亲并失去活胎，此方主治此症。
药材：蟹爪（一升）、阿胶（三两）、甘草（二两）。
制法：以上药材切碎，取东流水一斗，先煮蟹爪和甘草至三升，去渣，加入阿胶使其溶化，一次性服下。如果不能一次喝完，可分两次服用。（注：阿胶固护胎元，蟹爪破除瘀血，甘草调和脾胃，三者并行不悖，真是奇妙。）
下胎方：治疗孕妇因疾病导致胎不能安，可以下胎。
方法一：取七月七日制作的面曲（《大全》中写作曲）四两，水两大盏，煎取一盏三分，用绵布过滤去渣，分三次温服，胎儿即可立即排出。
又一方：大曲五升，清酒一斗，煮沸两次，去渣，分五次服用。服药当晚禁食。只要再服一次，胎儿就会化为糜状，母亲没有疾苦，这是千金不传的妙方。
又一方：麦蘖（麦蘖能破血）一升研为末，和水煮至二升，服用后即可排出，效果神奇。
又一方：附子二枚研为末，用纯醋调和涂抹右脚，去掉后效果很好。
又一方：取鸡蛋一枚，用三指撮量的盐放入鸡蛋中，服用后胎儿立即排出。
Quan Da (General Collection) states: During pregnancy, if the body is emaciated or complicated by diseases, leading to deficiency and damage of the Zang-Fu organs, and exhaustion of Qi and Blood, the fetus cannot be nourished. This results in fetal movement instability and lack of firmness. If the fetus ultimately cannot be secured, abortion may be induced to prevent harm to the pregnant woman.
Xue Ji (Mr. Xue) stated: The aforementioned syndrome should be treated according to the formulas and discussions in the "Lumbar, Abdominal, and Back Pain Section." Only when the fetus is truly unsaveable should one consider inducing abortion; extreme caution is required!
When Lord Xu Shaowei, Grand Censor, served as the magistrate of Jintan, his wife suffered from Tai Lou (threatened miscarriage with vaginal bleeding). Despite treatment, it did not stop. With the deadline for official assessment approaching, Lord Xu wished to follow the pathological trend to induce abortion and sought my advice. I simply instructed him to administer Foshou San (Buddha's Hand Powder), stating that if the fetus could be saved, so be it; if not, let it pass, following nature. After several doses, Lord Xu remained anxious and hesitant. A female gynecologist reviewed the prescription and suggested using Niu Xi (Achyranthes Root) one qian, decocted in wine. She claimed, "Niu Xi is essentially a tonic for the lower part of the body; what harm could it do?" Lord Xu believed her and administered it, and the fetus was indeed expelled. At that time, I was mourning the death of my mother and was unaware of this incident. When I learned of it and rushed to arrive, I smelled strong aromas of Rou Gui (Cinnamon Bark) and She Xiang (Musk) filling the hall. It turned out that because the placenta had not been expelled, the female doctor had further prescribed Xiang Gui San (Fragrant Cinnamon Powder). Consequently, blood gushed forth violently like a bursting river, impossible to stop. An urgent decoction of Dushen Tang (Single Ginseng Decoction) was prepared, but before it was ready, she passed away. After Lord Xu's grief subsided slightly, he came to thank me and asked, "Niu Xi is a tonic, yet it causes abortion. Why?" I replied, "Raw Niu Xi has a dispersing and promoting action, while cooked Niu Xi has a tonifying action (The theory of 'raw disperses heat and tonifies' seems plausible but is actually incorrect; please reflect on this). Therefore, breaking blood and replenishing essence are mutually exclusive, like arrowheads facing each other. Is it only Niu Xi that acts this way? Lu Jiao (Deer Antler) can also cause abortion and break blood, but when decocted into Bai Jiao (similar to E-Jiao), it secures the fetus and stops bleeding. Mistaking the raw properties based on familiarity with the cooked properties is what we call a crude practitioner (incompetent physician). Lord Xu sighed in regret endlessly. I have specially recorded this as a warning to the world.
Guixin San (Cinnamon Heart Powder): Treats cases where pregnancy is complicated by illness, making the fetus unstable, allowing for abortion.
Ingredients: Guixin (Cinnamon Heart), Gualou (Trichosanthes Fruit), Niu Xi (Achyranthes Root), Qumai (Dianthus Herb) (each 5 fen); Danggui (Angelica Sinensis Root) (1 qian).
Preparation: Coarsely crush the herbs, decoct in water, and take orally.
Another formula: Use only Niu Xi (Achyranthes Root) one liang, decocted in one zhong of wine until reduced to seven-tenths. Divide into two doses.
Qianjin Shenzao Tang: In women, if the pulse at Yin and Yang positions is both vigorous, it is called Shuang Qu (twins). If the Shaoyin pulse is slightly tight, the blood becomes turbid and coagulated. Due to insufficient nourishment via the menses, one fetus may die prematurely while the other survives alone. If the dead fetus is not removed, it will endanger the mother and result in the loss of the living fetus. This formula treats this condition.
Ingredients: Xiezhua (Crab Claws) (1 sheng), Ejiao (Donkey-Hide Gelatin) (3 liang), Gancao (Licorice Root) (2 liang).
Preparation: Coarsely crush the herbs. Take ten dou of flowing water from the east. First decoct Xiezhua and Gancao until reduced to three sheng. Strain to remove dregs, add Ejiao and melt it. Take all at once. If unable to consume all at once, divide into two doses. (Note: Ejiao secures the fetus, Xiezhua breaks blood stasis, and Gancao harmonizes the middle jiao. They work together without conflict; how miraculous.)
Xitai Fang (Abortion Formula): Treats pregnant mothers whose fetuses are unstable due to disease, allowing for abortion.
Method 1: Take Si Mian (Qu made on the seventh day of the seventh lunar month) (referred to as Qu in Quan Da) four liang. Add two large zhan of water, decoct to obtain one zhan and three-tenths. Filter through silk cloth to remove dregs. Divide into three warm doses. The fetus will be expelled immediately.
Another method: Take Da Qu (Large Qu) five sheng, decoct with one dou of clear wine for two boils. Strain to remove dregs. Divide into five doses. Do not eat food overnight after taking. Upon subsequent dosing, the fetus will turn into mush, and the mother will suffer no distress. This is a secret recipe of Qianjin Hospital.
Another method: Mai Ya (Sprouted Barley) (Mai Ya can break blood) one sheng, ground into powder. Mix with water and decoct to two sheng. Take orally; expulsion occurs immediately. Highly effective.
Another method: Take two Fu Zi (Aconite Lateral Root) pieces, grind into powder. Mix with pure sour vinegar and apply to the right foot. Remove after application; effect is excellent.
Another method: Take one chicken egg. Place salt measured by three fingers into the egg. Consume orally; expulsion occurs immediately.
Commentary: Chen Liangfu listed formulas such as Niuxi Tang and Guixin San, but Lou Quanshan did not adopt them, selecting only these few formulas instead. His insight was indeed outstanding.
