凡妊娠经水，壅之以养胎，蓄之以为乳，其冲任气虚。不能约制，故月水时下，名曰胞漏，血
尽子死。然亦有妊娠血盛，月信常来而胎不动。俗呼狗儿胎也。若以漏胎治之，则胎必坠；若不以
漏胎治之，其胎未必坠。亦有脉见滑数，而别无风热病，经脉如常，但较前略少，此因胎小，血盛
有余而然，俟迟至三、四月外，儿大能饮，经脉自止。又有壮盛孕妇，按月去血点滴，若无腰酸胎
动，不须服药，此血气强盛，孕至四、五月后，自然经止。如孕妇虚羸，腰常酸痛，并胎动而按月
下血点滴，或下血不止，此非血有余，乃胎漏也。宜服加味补中安胎饮。又云∶胎漏多因于血热，然
亦有气虚血少。服凉药而下血益甚，食少体倦者，此脾气虚而不能摄血也，宜归脾等方加减。当以
脉候察之，凡坠胎之病，多在三、五、七月，如前次三月会坠，后必如期乘其所虚而亦坠，必预服
尊生安胎饮，或胎元饮加减用之，当服过七月，可无患矣。更宜戒房欲、气恼、劳役、 炙诸食，至
于顿仆伤动胎气，宜服胶艾安胎散。总属妊娠气血虚弱，胎元不固。盖气虚则提摄不固，血弱则灌
溉不周，多致小产。况妇人肾以系胞，而腰为肾之腑，腰痛则坠，不可不防。大凡妊娠三月后，尺
脉或涩或微弱，胎必不固，惟脉洪盛者，胎不坠耳。所以《脉诀》内云∶胎脉弦牢滑利安，沉细而微
归泉路。正此之谓也。总之，三月以前宜养脾胃，四月以后宜壮腰肾，补血顺气，佐以清热，此大法也。

凡是妊娠期间的月经，本应壅滞以滋养胎儿，蓄积以化为乳汁，但如果冲任二脉气虚，不能约束经血，导致每月仍有少量出血，这就叫做“胞漏”，如果血液耗尽，胎儿就会死亡。然而也有妊娠期间血气旺盛，月经照常来潮但胎儿安稳不动的情况，俗称为“狗儿胎”。如果用治疗漏胎的方法去治它，胎儿必定会流产；如果不把它当作漏胎来治，胎儿未必会流产。也有脉象呈现滑数，但没有风热病症，经脉流量如常，只是比平时略少，这是因为胎儿较小，血气旺盛有余所致，等到怀孕三、四个月以后，胎儿长大需要更多营养，经脉自然就会停止。又有身体强壮的孕妇，每个月只有点滴出血，如果没有腰酸和胎动不安的症状，不需要服药，这是因为气血强盛，怀孕到四、五个月以后，月经自然会停止。如果孕妇身体虚弱消瘦，腰部经常酸痛，并伴有胎动且按月有少量出血，或者出血不止，这并非血气有余，而是胎漏。适宜服用加味补中安胎饮。又说：胎漏多因血热引起，但也有气虚血少的情况。服用凉药后出血反而加重，饮食减少、身体疲倦的，这是脾气虚弱不能统摄血液，适宜用归脾汤等方剂加减治疗。应当通过脉诊来观察，凡是导致堕胎的疾病，多发生在怀孕第三、第五、第七个月，如果前次在三个月时发生堕胎，后次必然也会因为此时正气虚弱而再次堕胎，必须预先服用尊生安胎饮，或胎元饮加减使用，只要服过七个月后，就可以没有忧患了。更应当戒除房事、生气恼怒、过度劳累以及辛辣炙烤食物，至于因跌倒仆伤损伤胎气的，适宜服用胶艾安胎散。这些总属于妊娠期间气血虚弱，胎元不稳固。因为气虚则提摄无力而不固，血弱则灌溉不足，多导致小产。况且妇人肾脏系连子宫，而腰部是肾脏的外腑，腰痛则预示胎坠，不可不预防。大凡怀孕三个月以后，尺脉如果涩滞或微弱，胎儿必定不稳固，只有脉象洪大盛实的，胎儿才不会流产。所以《脉诀》中说：胎脉弦牢滑利则平安，沉细而微则归黄泉（指死亡）。正是这个意思。总之，怀孕三个月以前宜调养脾胃，四个月以后宜壮腰补肾，补血顺气，佐以清热，这是大法。
加味补中安胎饮：人参（一钱），白术（土炒），当归（各二钱，酒洗），川芎，黄芩（各八分），紫苏，陈皮，砂仁（捣碎），炙甘草（各四分）。
尊生安胎饮：也治疗胎动、胎漏。当归身（酒洗），白芍（酒炒），熟地黄，生地黄，砂仁，阿胶（各一钱，炒成珠状），杜仲（盐水炒，去丝），白术（各二钱，土炒），条芩（一钱五分），续断肉（八分，酒制），川芎，陈皮，苏梗（各五分）。
景岳胎元饮：治疗妇人冲任二脉失守，胎元不安不稳固，可以隔日或每两三天服用一、二剂。人参随证用量，当归（酒洗），杜仲（盐水炒断丝），白芍（各二钱，酒炒），熟地黄（二三钱），白术（一钱半，土炒），陈皮（七分，无气滞者不必用），炙甘草（一钱）。用水二钟，煎至七分，饭后服用。如果下元不固而多遗精浊液的，加炒山药、炒补骨脂、五味子之类；气分虚损严重的，加倍白术，加灸黄芪，但是黄芪、白术之气浮散，容易阻滞胃口，如果胸膈有饱闷不适感的，须慎用。如果体虚兼寒且多呕吐的，加炮姜七八分或一二钱；如果体虚兼热的，加酒炒黄芩一钱半，或加生地黄二钱，去掉杜仲；如果阴虚小腹作痛的，加枸杞二钱；如果因受到触动而动血的，加制续断肉、炒阿胶各一二钱。

Any menstrual flow during pregnancy should be retained to nourish the fetus and stored to transform into milk. However, if Qi of Chong and Ren (Thrusting and Conception vessels) is deficient and unable to constrain the blood, causing monthly bleeding, it is named Bao Lou (Uterine Bleeding). If the blood is exhausted, the fetus will die. Yet, there are cases where pregnant women have abundant blood, menstruation continues regularly, but the fetus remains stable; this is colloquially called "Gou'er Tai" (Dog Fetus). Treating this as Bao Lou would cause miscarriage; not treating it as such may allow the pregnancy to continue. There are also cases with slippery and rapid pulse, without wind-heat pathology, with normal but slightly reduced menstrual flow, due to a small fetus and surplus blood; after three or four months, when the fetus grows larger and consumes more nutrients, the flow will naturally cease. In robust pregnant women who experience only drop-by-drop bleeding monthly, without lower back soreness or fetal movement, no medication is needed as Qi and Blood are strong, and menstruation will stop naturally by the fourth or fifth month. Conversely, if a pregnant woman is emaciated, suffers from frequent lower back soreness, has fetal movement, and experiences monthly spotting or continuous bleeding, this is not blood surplus but Tai Lou (Fetal Leakage). Jiawei Buzhong Antai Yin (Modified Decoction for Supplementing the Middle and Calming the Fetus) is appropriate. It is said that Tai Lou is often caused by Blood Heat, but can also result from Qi deficiency and Blood insufficiency. If cooling herbs worsen bleeding and lead to poor appetite and fatigue, it indicates Spleen Qi deficiency failing to control blood; Guipi Tang (Restore the Spleen Decoction) and similar formulas should be used with modifications. Pulse diagnosis is essential. Diseases leading to miscarriage often occur in the third, fifth, and seventh months. If a previous miscarriage occurred at three months, subsequent ones will likely happen at the same time due to periodic Qi deficiency; Zunsheng Antai Yin (Decoction for Nourishing Life and Calming the Fetus) or Taiyuan Yin (Decoction for the Fetal Origin) should be taken prophylactically. After passing the seventh month, danger usually subsides. One must abstain from sexual intercourse, anger, overwork, and spicy/fried foods. For trauma from falling that damages fetal Qi, Jiao'ai Antai San (Donkey-hide Gelatin and Mugwort Powder for Calming the Fetus) is suitable. These conditions generally stem from Qi and Blood deficiency during pregnancy, leading to unstable fetal origin. Qi deficiency fails to hold, and Blood weakness fails to nourish adequately, often resulting in spontaneous abortion. The Kidney connects to the uterus, and the waist is the exterior of the Kidney; lower back pain predicts fetal descent and must be prevented. Generally, after three months of pregnancy, if the Chi (Cun Cun) pulse is choppy or weak, the fetus is unstable; only a surging and full pulse indicates stability. As stated in Mai Jue (Pulse Classic): "Slippery, firm, and smooth pulses indicate safety; deep, fine, and minute pulses lead to death." This is precisely what is meant. In summary, before the third month, nourish the Spleen and Stomach; after the fourth month, strengthen the waist and Kidneys, tonify Blood, regulate Qi, and assist with clearing heat. This is the general principle.
Jiawei Buzhong Antai Yin: Renshen (Ginseng Radix et Rhizoma, 1 qian), Baizhu (Atractylodis Macrocephalae Rhizoma, earth-fried), Danggui (Angelicae Sinensis Radix, 2 qian each, wine-washed), Chuanxiong (Ligusticum Chuanxiong Rhizoma), Huangqin (Scutellariae Radix, 0.8 fen each), Zisu (Perillae Folium), Chenpi (Citri Reticulatae Pericarpium), Sharen (Amomi Fructus, crushed), Zhigancao (Glycyrrhizae Radix et Rhizoma Preparata, 0.4 fen each).
Zunsheng Antai Yin: Also treats Taidong (Fetal Movement) and Tailou. Guishen (Angelicae Sinensis Radix, wine-washed), Baishao (Paeoniae Radix Alba, wine-fried), Shudihuang (Rehmanniae Radix Preparata), Shengdihuang (Rehmanniae Radix), Sharen, Ejiao (Asini Corii Colla, 1 qian each, fried until pearl-like), Duzhong (Eucommiae Cortex, salt-water fried, fibers removed), Baizhu (2 qian each, earth-fried), Tiaohuangqin (Scutellariae Radix, 1.5 qian), Xuduan (Dipsaci Radix, 0.8 fen, wine-processed), Chuanxiong, Chenpi, Sugeng (Perillae Caulis, 0.5 fen each).
Jingyue Taiyuan Yin: Treats women with loss of Chong and Ren containment, unstable fetal origin. Take one or two doses every other day or every two to three days. Renshen (dosage varies), Danggui (wine-washed), Duzhong (salt-water fried, fibers broken), Baishao (2 qian each, wine-fried), Shudihuang (2-3 qian), Baizhu (1.5 qian, earth-fried), Chenpi (0.7 fen, omit if no stagnation), Zhigancao (1 qian). Decoct with two zhong of water to seven-tenths volume, take far from meals. If Lower Yuan is insecure with frequent seminal emission or turbid discharge, add Chao Shanyao (Dioscoreae Rhizoma, stir-fried), Chao Buguzhi (Psoraleae Fructus, stir-fried), Wuweizi (Schisandrae Chinensis Fructus). If Qi deficiency is severe, double Baizhu and add Jiu Huangqi (Astragali Radix, roasted); however, Huangqi and Baizhu have floating Qi and may obstruct the stomach; use cautiously if chest/epigastrium feels full or uncomfortable. If deficiency with cold causes vomiting, add Paojiang (Zingiberis Rhizoma Preparatum, 0.7-1 fen or 1-2 qian). If deficiency with heat, add Jiu Huangqin (Scutellariae Radix, wine-fried, 1.5 qian) or Shengdihuang (2 qian), remove Duzhong. If Yin deficiency causes lower abdominal pain, add Gouqi (Lycii Fructus, 2 qian). If agitation causes bleeding, add Zhi Xuduan (Dipsaci Radix, processed) and Chao Ejiao (Asini Corii Colla, stir-fried, 1-2 qian each).
