受孕分房宜静养，谨戒食味使脾安，调其喜怒防惊恐，慎厥起居避风寒。
【注】受孕之后，分房静养，恐动相火，致生胎毒。谨戒饮食五味，使其脾胃调和，母
之气血易生，子之形成必育。内调七情，外避风寒，起居安顺，不持重用力，不安逸多
睡，不登高涉险，则母无病，子亦安矣！
安胎之道有二法，母病胎病要详分∶母病动胎但治母；子病致母审胎因。
【注】安胎之道有二法，母病、胎病当详分而施治也。凡因母病以致胎动者，但疗其
母，母安则胎自安；或因胎病有所触动，以致母病者，但宜安胎，胎安则母自愈矣。
胎前清热养血主，理脾疏气是为兼。三禁汗下利小便，随证虚实寒热看。
【注】丹溪曰∶胎前当清热养血为主，恐伤阴血也。理脾脾健，则气血易生；疏气气
顺，则气血调和。理脾疏气，兼以清热养血，则胎自安矣。三禁者，汗、下、利小便也，盖
恐过汗亡阳伤气，过下亡阴伤血，利小便伤津液也。然又当随证详审表里、虚实、寒热，
以施其治，不可过峻也。
形瘦不宜过热品，体盛补气恐动痰。安胎芩术为要药，佐以他药任抽添。火盛倍芩痰倍术，血虚四
物气四君。杜续胶艾胎不稳，气盛苏腹枳砂陈。
【注】形瘦之人多火，过用温热则伤阴血。肥盛之人多痰，过于补气，恐壅气动痰。白
术消痰健脾，条芩清热养阴，二味为安胎要药，若有他证，则以药佐之，或减白术加条
芩，或加白术减条芩，任其抽添。如火盛，则当倍芩以清火；痰盛，则当倍术以消痰；血
虚，则合四物汤以补血；气虚，则合四君汤以补气；胎不安稳，更佐以杜仲、续断、阿
胶、艾叶以安之；若气盛胎高，则加紫苏、大腹皮、枳壳、砂仁、陈皮以舒之。

受孕之后应当分床而居，保持心境宁静并注重休养，谨慎节制饮食五味以使脾胃安宁，调节情绪以防喜怒过度，警惕惊恐，小心起居生活以避开风寒。
【注】怀孕之后，夫妻应分房居住并静养，以免因性事扰动相火（指寄居于肝肾、主司生殖功能的阳气），导致产生胎毒。谨慎节制饮食中的酸、苦、甘、辛、咸五味，使脾胃功能调和，母亲的气血容易生成，胎儿的发育必然健壮。在内调理七情（喜、怒、忧、思、悲、恐、惊），在外躲避风寒，起居安顺，不从事重体力劳动，不过度安逸多睡，不登高涉险，这样母亲就不会生病，胎儿也能安稳！
安胎的方法有两种，必须详细区分是母病还是胎病：如果是母亲生病导致胎动不安，只需治疗母亲的疾病；如果是胎儿病变导致母亲身体不适，需审察胎儿的原因进行治疗。
【注】安胎之道有两种方法，母病和胎病应当详细区分后施治。凡是因母亲患病而导致胎动的，只治疗母亲，母亲安好则胎儿自然安定；或者因为胎儿有病有所触动，导致母亲生病的，只宜安胎，胎儿安定则母亲自然痊愈。
妊娠期间以清热养血为主要原则，调理脾胃、疏通气机作为辅助兼治。严禁使用发汗、攻下、利小便三种疗法，需根据证候的表里、虚实、寒热情况进行辨证施治。
【注】朱丹溪说：妊娠期间应当以清热养血为主，因为担心损伤阴血。调理脾胃使脾脏健运，则气血容易生成；疏通气机使气行顺畅，则气血调和。调理脾胃、疏通气机，兼以清热养血，则胎儿自然安定。所谓的“三禁”，是指发汗、攻下、利小便这三种疗法，因为担心过汗会亡阳伤气，过下会亡阴伤血，利小便会损伤津液。然而又应当根据证候详细审察表里、虚实、寒热，从而实施治疗，不可用药过于峻猛。
形体消瘦者不宜使用过热性质的药物，形体肥胖者补气恐怕会引动痰湿。安胎以黄芩、白术为关键药物，配合其他药物可根据情况随意增减。若火热旺盛加倍使用黄芩，痰湿旺盛加倍使用白术，血虚用四物汤，气虚用四君子汤。杜仲、续断、阿胶、艾叶用于胎动不稳，气盛导致腹部胀满用紫苏梗、大腹皮、枳壳、砂仁、陈皮。
【注】形体消瘦的人多内火，过度使用温热药物则会损伤阴血。形体肥胖的人多痰湿，过于补气，恐怕会导致气机壅滞而动生痰湿。白术能消除痰湿、健脾，条芩（即黄芩）能清热养阴，这两味药是安胎的关键药物，如果有其他证候，则以药物佐助，或者减少白术增加条芩，或者增加白术减少条芩，任由医生灵活加减。如果火热旺盛，就应当加倍使用黄芩来清火；痰湿旺盛，就应当加倍使用白术来消痰；血虚，就合用四物汤来补血；气虚，就合用四君子汤来补气；胎动不安稳，更佐以杜仲、续断、阿胶、艾叶来安胎；如果气机壅盛导致胎位偏高或腹部胀满，则加紫苏、大腹皮、枳壳、砂仁、陈皮来舒展气机。
四物汤 四君子汤（方剂均见首卷汇方内）
After conception, couples should sleep in separate rooms, maintain mental tranquility, and focus on rest. One must carefully regulate the intake of the five flavors (sour, bitter, sweet, pungent, salty) to ensure the harmony of the Spleen and Stomach, modulate emotions to prevent excessive joy or anger, guard against fright, and be cautious with daily activities to avoid wind and cold.
[Note] After conception, separating from one's partner and resting quietly is advised to prevent the stirring of Ministerial Fire (Xianghuo, referring to the Yang qi residing in the Liver and Kidney that governs reproduction), which could lead to the generation of fetal toxins. Carefully regulating the diet avoids the excess of the five flavors, ensuring the harmonious function of the Spleen and Stomach. This facilitates the generation of Qi and Blood in the mother, ensuring the healthy development of the fetus. Internally, regulate the Seven Emotions (Joy, Anger, Worry, Pensive, Sorrow, Fear, Fright); externally, avoid wind and cold. Maintain a smooth daily routine: do not engage in heavy labor, do not be overly sedentary and sleep excessively, and do not climb heights or venture into dangerous places. In this way, the mother will remain disease-free, and the fetus will be secure.
There are two methods for stabilizing the fetus; it is essential to distinguish whether the pathology originates from the mother or the fetus. If the mother's illness causes fetal movement, treat only the mother. If the fetus's pathology causes maternal symptoms, examine the cause related to the fetus.
[Note] There are two approaches to stabilizing the fetus: the pathologies of the mother and the fetus must be distinguished for treatment. Whenever fetal movement is caused by the mother's illness, treat the mother; once the mother is stabilized, the fetus naturally becomes stable. Conversely, if the mother falls ill due to a disturbance caused by fetal pathology, stabilize the fetus; once the fetus is stable, the mother will naturally recover.
During pregnancy, clearing heat and nourishing blood are the primary principles, while regulating the Spleen and unblocking Qi serve as secondary adjunctive treatments. Sweating (Han), purging (Xia), and promoting urination (Li Xiaobian) are strictly prohibited. Treatment must be administered according to the specific syndrome patterns of exterior/interior, deficiency/excess, and cold/heat.
[Note] Zhu Danxi stated: During pregnancy, the primary approach should be clearing heat and nourishing blood, as there is a concern about damaging Yin and Blood. Regulating the Spleen ensures its robust function, facilitating the generation of Qi and Blood; unblocking Qi ensures smooth flow, harmonizing Qi and Blood. By regulating the Spleen, unblocking Qi, and simultaneously clearing heat and nourishing blood, the fetus will naturally stabilize. The "Three Prohibitions" refer to sweating, purging, and promoting urination. Excessive sweating may lead to the loss of Yang and damage Qi; excessive purging may lead to the loss of Yin and damage Blood; promoting urination may injure Body Fluids. However, treatment must still be tailored after carefully examining the exterior/interior, deficiency/excess, and cold/heat aspects of the syndrome, avoiding overly harsh medications.
For individuals with a thin physique, overly hot-natured substances should be avoided. For those with a robust or obese physique, tonifying Qi may risk stirring Phlegm. Huangqin (Scutellariae Radix) and Baizhu (Atractylodis Macrocephalae Rhizoma) are the key herbs for stabilizing the fetus; other herbs can be added or removed as needed. If Fire is excessive, double the dosage of Huangqin; if Phlegm is excessive, double the dosage of Baizhu. For Blood deficiency, use Siwu Tang (Four Substances Decoction); for Qi deficiency, use Sijunzi Tang (Four Gentlemen Decoction). For unstable fetus, add Duzhong (Eucommiae Cortex), Xuduan (Dianthi Herba), Ejiao (Colla Corii Asini), and Aye (Folium Artemisiae Argyi). For Qi stagnation causing abdominal distension, add Zisu (Perillae Folium), Dafupi (Arecae Pericarpium), Zhike (Aurantii Fructus), Sharen (Amomi Fructus Rotundus), and Chenpi (Citri Reticulatae Pericarpium).
[Note] Individuals with a thin body type tend to have internal Heat; using too many warm-hot substances will damage Yin and Blood. Individuals with a robust body type tend to have Phlegm-Dampness; excessive Qi tonification may cause Qi stagnation and stir up Phlegm. Baizhu eliminates Phlegm and strengthens the Spleen; Tiaohuangqin (prepared Scutellariae Radix) clears Heat and nourishes Yin. These two herbs are the essentials for stabilizing the fetus. If other syndromes are present, they can be used as adjuvants. One may reduce Baizhu and increase Tiaohuangqin, or increase Baizhu and reduce Tiaohuangqin, adjusting freely based on the situation. If Fire is excessive, double Huangqin to clear Heat; if Phlegm is excessive, double Baizhu to resolve Phlegm; for Blood deficiency, combine with Siwu Tang to tonify Blood; for Qi deficiency, combine with Sijunzi Tang to tonify Qi. For an unstable fetus, adjuvantly use Duzhong, Xuduan, Ejiao, and Aye to stabilize it. If Qi stagnation leads to a high fetal position or abdominal distension, add Zisu, Dafupi, Zhike, Sharen, and Chenpi to soothe the Qi.
Siwu Tang (Four Substances Decoction) and Sijunzi Tang (Four Gentlemen Decoction) formulas are found in the compiled prescriptions of the first volume.
