一、因安逸：大概妇人怀孕，靠血来滋养胎儿，靠气来护卫胎儿。应当经常活动身体，使气血流通，胞胎活跃。如果久坐久卧，导致血液凝滞、气机阻滞，就会造成难产。常见田间劳作的妇女生产很容易，由此可知。
二、因奉养（饮食过度）：胎儿的肥瘦，与母体气息相通。如果放纵食欲，食用浓腻厚味的食物，导致胎儿过肥而难产。常见穿着荆布（粗布衣服）的贫家女子容易生产，可以证明这一点。
三、因淫恣（房事不节）：古代有孕的妇女，就居住在单独的房间，不与丈夫同寝。如果有孕而行房事，三个月以前行房，常会导致胎动不安、流产或小产；三个月以后行房，一方面胞衣太厚而导致难产，另一方面胎儿体内多浊物而不长寿，第三方面胎儿出生时胞衣上多有疮毒，出痘疹细密难以起发，以致夭折。这都是由父母欲火凝结所致，可悲啊。
四、因忧疑：现在的人不讲求生产的道理，有的向鬼神询问祸福，向卜筮祈祷；有的听说乡里有生产遭遇厄运的人，孕妇心生疑虑则恐惧，恐惧则气机怯弱，所以难产。
五、因软怯（体质虚弱/胆怯）：如年轻妇女初次生产，神气怯弱，子户（子宫）未舒展，便弯腰曲背不能伸直，辗转侧身，胎儿不得产出。又有中年妇女，生育过多，气血虚耗，生产非常艰难。必须在胎前服用补气养血的药物，调理至健壮，那么临产时就没有忧虑了。
六、因怆惶（惊慌失措）：即将生产的时候，有一些愚蠢的稳婆（接生婆），不审察是正产还是胎位不正（转胎），只看见腹痛，就用力催促分娩，产妇听从，导致胎儿横生。
七、因虚乏（过早用力）：临产时用力太早，等到胎儿要出来时无力推送，因此难产。此时宜服用人参接力，就能顺利生产。
凡是孕妇脾胃旺盛且气血充盈，则胎儿安稳端正，出生后精神饱满且长寿，何尝需要用药来调气血安胎呢？如果禀赋不足而气血衰弱，脾胃虚弱，饮食减少，则虚症百出，怀孕多次流产，或者生子不长寿，必须借助药力来帮助母亲安胎并延长子女寿命。因此丹溪先生删定安胎饮这一良方，治疗孕妇元气虚弱，胎气不安，饮食不佳，或腹痛腰痛，随症状加减，以治疗胎前诸症，后面列出随症加减二十余方，都可以按方取用。血精汇聚凝结而成孕，精气蒸腾胃腑而致呕逆。血少肝虚，如喜爱酸味食物；胃气受伤，厌恶阻碍饮食。如果人素体虚弱且有呕阻症状，本方适量加入橘红；如果禀赋浓厚且吐逆，再加竹沥和姜汁。下血不止称为胎漏；小腹坠痛称为胎痛。胎漏宜凉，须加生地黄、熟地黄；胎痛宜温，少加带壳砂仁。至于跌倒损伤动胎而下血，胶艾汤宜加入；怒气冲逆胎气上行，木香为先导。小便短涩成淋沥，这是子淋的症状，安荣不应本方宜（此处原文似有脱误或特定语境，意指需调整方剂）。小便带血流于膀胱，是膀胱之热，逍遥散入炒山栀。子肿症多面目虚浮，而肢体有水气，全生白术可医治。子烦症则心惊胆怯，而时常加上烦闷，安胎竹叶无疑。天仙藤散治疗足指缝出水，病名子气，虚人多加人参、白术。羚羊角散治疗项强筋搐拳挛，病名子痫，痰多加竹沥、人参、当归。至于脾胃气虚而胎压迫尿胞，则脐腹胀而小便淋闭，服安胎饮，治法宜探吐升提。又如脾虚气弱而转运迟缓，则饮食停滞而腹胀呕吐，安胎力缓，加人参，平胃散调和。又若胸满、腹胀、便秘、遍身浮肿，名曰胎水之不利，得用鲤鱼汤。若脾胃气虚，佐以四君子汤、五皮饮。又若胎气上攻，心腹胀满作痛，名曰子悬之候，必用紫苏汤。若食少午后发热，兼以加味逍遥散。若腹大子满，肥而气壅，束胎难缓，临月欲活血而散滞，达生散宜尝试。柴前梅连丸，治疗骨蒸之劳热。当归六黄汤，治疗盗汗之午后发热。怀孕多次流产，因母血弱不能分荫其胎，本方预服，可保满期。生子无气，由母气虚，仅可资荣于己，安胎之方，必须每月服用。老夫娶少妇，须寡欲以等候经期；壮阳遇衰阴，必频药以助胎力。其人爱惜精气慎重施泄，生于精神充沛而有寿。狂阳妄泄，育子清寡无神，这是造化必然的道理，后人繁衍后代应当借鉴。大抵孕妇素体虚弱，又要分血气以荫庇胎儿，自然虚症百出。因此丹溪先生安胎方以补为主，佐以顺气清凉。人参、白术、黄芩，乃是安胎的圣药；当归、川芎、怀熟地，实为补血的良剂；佐以苏叶、陈皮，可作为常服方。怀孕六个月之前，其胎尚未转运，茯苓性降，不宜多用，黄耆肥胎，岂可常加。香附虽胎喘所需，无补虚人反害。砂仁可止呕定痛，多加则动血行胎。历考丹溪安胎之论不过数首，安胎之方不过再四，若能神明加减，则十全八九，诚为后学之准绳也。
One, due to excessive comfort: Generally, during pregnancy, a woman relies on blood to nourish the fetus and Qi to protect it. She should engage in regular physical activity to ensure the free flow of Qi and Blood, keeping the fetal sac active. Prolonged sitting or lying down causes Blood stasis and Qi stagnation, leading to difficult labor. It is commonly observed that women engaged in field labor deliver easily, which confirms this principle.
Two, due to dietary excess: The fatness or thinness of the fetus is connected to the mother's Qi. Indulging in rich and heavy flavors leads to an overly large fetus, causing difficult labor. This is evidenced by the fact that women from humble backgrounds (wearing coarse cloth) often deliver easily.
Three, due to sexual indulgence: In ancient times, pregnant women lived in separate quarters and did not cohabit with their husbands. If intercourse occurs during pregnancy, before three months, it often results in threatened miscarriage or spontaneous abortion; after three months, it may cause the placenta to become too thick, leading to difficult labor. Additionally, the fetus may accumulate turbid substances, resulting in short life expectancy. Furthermore, the newborn may suffer from sores and toxins on the placenta, with smallpox appearing dense and difficult to erupt, leading to early death. All these are caused by the accumulation of parental lustful fire, which is truly pitiable.
Four, due to worry and doubt: Modern people do not understand the principles of childbirth. Some ask spirits and gods about fortune and misfortune, or pray through divination. Hearing of others who suffered complications during childbirth, pregnant women become suspicious and fearful. Fear leads to deficient Qi, resulting in difficult labor.
Five, due to timidity and weakness: For young women giving birth for the first time, if their Shen (Spirit) and Qi are timid and weak, and the Zi Hu (uterus) has not yet expanded, they may bend their waist and be unable to straighten up, tossing and turning without being able to expel the child. Similarly, middle-aged women who have given birth many times may suffer from depleted Qi and Blood, making delivery very difficult. They must take medicines to tonify Qi and nourish Blood before pregnancy, conditioning themselves to robust health, so there will be no worries at the time of delivery.
Six, due to panic and confusion: At the time of impending labor, some foolish midwives fail to distinguish between normal delivery and malpresentation. Seeing only abdominal pain, they urge the mother to exert effort to hasten delivery. If the mother complies, it may result in transverse presentation.
Seven, due to exhaustion: Exerting effort too early during labor, followed by a lack of strength to push when the baby is ready to emerge, causes difficult labor. At this time, taking Ginseng to provide support can facilitate delivery.
Generally, if a pregnant woman's Spleen and Stomach are vigorous and her Qi and Blood are abundant, the fetus remains stable and upright, and the child will be spirited and long-lived. Why would medication be needed to regulate Qi and Blood for calming the fetus? However, if one has insufficient constitutional endowment, with deficient Qi and Blood, weak Spleen and Stomach, and poor appetite, various deficiency syndromes will arise. Repeated miscarriages may occur, or the child may be born frail and short-lived. In such cases, medicinal support is necessary to help the mother calm the fetus and ensure the child's longevity. Therefore, Mr. Danxi edited the excellent prescription "Antai Yin" (Calming Fetus Decoction) to treat pregnant women with deficient Yuan Qi, unstable fetal Qi, poor appetite, abdominal pain, or lower back pain. Modifications are made according to symptoms to treat various antenatal conditions. More than twenty modified prescriptions follow, all of which can be used as indicated. Conception occurs when Jing (Essence) and Blood converge. Vomiting arises from the steaming of Stomach Qi by Essence and Qi. Deficient Blood and Liver Xu (deficiency) may manifest as a craving for sour foods; injured Stomach Qi may cause aversion to food. If a person is constitutionally weak with vomiting and obstruction, add Ju Hong (Tangerine Peel) to the base formula in appropriate amounts. If the constitution is rich and vomiting is severe, add Zhu Li (Bamboo Sap) and Jiang Zhi (Ginger Juice). Continuous bleeding is called Tai Lou (Fetal Leakage); lower abdominal distending pain is called Tai Tong (Fetal Pain). Tai Lou requires cooling properties; add Sheng Di Huang (Rehmannia Root) and Shu Di Huang (Prepared Rehmannia Root). Tai Tong requires warming properties; add Sha Ren (Amomum Fruit) with shell in small amounts. For trauma causing fetal movement and bleeding, Jiao Ai Tang (Collagen and Mugwort Decoction) should be added. For anger causing Qi rebellion affecting the fetus, Mu Xiang (Aucklandia Root) is prioritized. Scanty, dysuric urination constitutes Zi Lin (Pregnancy Dysuria); the An Rong formula is not suitable here. Blood in urine indicates Bladder Heat; Xiao Yao San (Free and Easy Wanderer Powder) with Chao Shan Zhi (Stir-fried Gardenia) is indicated. Zi Zhong (Pregnancy Edema) presents with puffy face and limbs with fluid retention; Quan Sheng Bai Zhu (Complete Life Atractylodes) can treat it. Zi Fan (Pregnancy Irritability) involves fright, palpitations, and occasional irritability; An Tai Zhu Ye (Calming Fetus Bamboo Leaf) is undoubtedly appropriate. Tian Xian Teng San (Celastri Vine Powder) treats fluid oozing from toe webs, known as Zi Qi (Pregnancy Gas); for deficient persons, add Ren Shen (Ginseng) and Bai Zhu (Atractylodes Macrocephala). Ling Yang Jiao San (Antelope Horn Powder) treats neck stiffness, muscle spasms, and clenched fists, known as Zi Xian (Pregnancy Eclampsia); for phlegm, add Zhu Li, Ren Shen, and Dang Gui (Angelica Sinensis). When Spleen and Stomach Qi deficiency causes the fetus to press on the bladder, resulting in umbilical and abdominal distension and urinary retention, Antai Yin is taken, and the method should involve inducing vomiting and lifting Qi. If Spleen deficiency and weak Qi cause slow transportation, leading to food stagnation, abdominal distension, and vomiting, the effect of Antai Yin is mild; add Ren Shen and Ping Wei San (Calm the Stomach Powder) to harmonize. If chest fullness, abdominal distension, constipation, and generalized edema occur, it is called Tai Shui Bu Li (Obstruction of Fetal Water); Li Yu Tang (Carp Decoction) is used. For Spleen and Stomach Qi deficiency, supplement with Si Jun Zi Tang (Four Gentlemen Decoction) and Wu Pi Yin (Five Peel Decoction). If fetal Qi attacks upward, causing heart and abdominal distension and pain, it is called Zi Xuan (Hanging Fetus); Zi Su Tang (Perilla Decoction) is essential. For poor appetite and afternoon fever, Jia Wei Xiao Yao San (Modified Free and Easy Wanderer Powder) is combined. For a large abdomen with a full fetus, obesity, and Qi congestion, where binding the fetus cannot relieve tension, near term, to invigorate Blood and dissipate stagnation, Da Sheng San (Generate Life Powder) should be tried. Chai Qian Mei Lian Wan (Bupleurum, Pinellia, Citrus, and Coptis Pill) treats bone-stealing fever. Dang Gui Liu Huang Tang (Angelica Sinensis and Six Yellow Decoction) treats night sweats and afternoon fever. Repeated miscarriages occur because maternal Blood is too weak to nourish the fetus; taking the base formula in advance ensures carrying to term. A newborn lacking vitality is due to maternal Qi deficiency, which only suffices to nourish the mother herself; formulas for calming the fetus must be taken monthly. An older man marrying a young woman must practice sexual restraint until the menstrual cycle is regular; a vigorous male with a declining female partner must frequently use medicine to assist fetal strength. One who cherishes Jing and practices moderation in ejaculation will have offspring with abundant Shen and longevity. One who recklessly wastes Yang and exhausts Jing will produce offspring who are sparse and devoid of spirit. This is the inevitable law of creation; future generations regarding progeny should take note. Generally, pregnant women who are constitutionally weak must share Qi and Blood to nourish the fetus, naturally leading to various deficiency syndromes. Therefore, Mr. Danxi’s formulas for calming the fetus focus primarily on tonification, assisted by regulating Qi and clearing heat. Ren Shen, Bai Zhu, and Huang Qin (Scutellaria Root) are the sacred herbs for calming the fetus; Dang Gui, Chuan Xiong (Ligusticum Chuanxiong), and Huai Shu Di (Rehmannia prepared with wine) are excellent agents for nourishing Blood; supplemented with Zi Su Ye (Perilla Leaf) and Chen Pi (Aged Tangerine Peel), they form a prescription suitable for regular use. Before six months of pregnancy, the fetus has not yet rotated; Fu Ling (Poria) has a descending nature and should not be used excessively. Huang Qi (Astragalus) promotes fetal fatness and should not be added regularly. Xiang Fu (Cyperus Rotundus) is needed for fetal panting but, lacking tonifying properties for deficiency, may cause harm. Sha Ren can stop vomiting and relieve pain, but excessive use moves Blood and induces labor. Examining Mr. Danxi’s discussions on calming the fetus, there are only a few main points and repeated modifications. If one can apply divine flexibility in modifications, success rates will reach eighty or ninety percent. This is indeed a standard for later learners.
