可不言而喻。
妊妇有因脾土为木邪所克，谷气不举，湿淫下流以滞阴血，而腹中 痛，当归芍药散主之。此与胎阻

凡是妇女脉象没有明显的病态，只有阴脉（尺脉）细小虚弱，这是营气不足的表现。如果感受外邪且营气不足，必然会出现怕冷和发热的症状。现在既不怕冷也不发热，只是感到饮食不便（食欲不振），由此可知是怀孕了。月经停止，到了六十天，血液聚集、气机搏击，才开始凝结成胎。营气都汇聚到胎元上，导致胃气不足，津液分布减少，所以这个人会口渴、不能进食，适宜用桂枝汤来调和营卫、补益胃气。如果医生把它当作其他疾病来治疗，反而加重了呕吐和下泻的症状，这就是恶阻病，应当立即停止医疗干预，等待其自行恢复即可。（桂枝能调和营卫并驱散邪气，配合芍药收敛阴气，甘草缓和药性，以生姜和大枣为引，辛甘性质的药物性温，能够运行脾脏的津液从而调和营卫，这样口渴就会停止。）
凡是妇女在行经期间遇到寒冷，残留的血液停滞而成为瘀血。然而患有瘀血病的妇女很常见，如果瘀血不阻碍子宫功能，仍然可以行经并受孕。虽然血液聚集形成了胎儿，但胎儿形成三个月后月经才完全断绝；如果在断绝之前不到三个月，瘀血病再次发作，就会导致阴道淋漓出血不止。瘀血在下焦，压迫胎儿，所以称为“痼害”（原有的顽固性疾病）。因此脐部上方感觉跳动不安，询问之后确认确实是正常的妊娠胎儿。如果是鬼胎（葡萄胎等异常妊娠），则属于阴气结聚，绝对不会有阳气活跃于阳位（脐上属阳）的道理。现在跳动出现在脐上，说明胎儿已经六个月大。推断前三个月月经虽然通畅，但胎儿已经形成；后三个月月经断绝，但血液积聚形成了瘀血，因此血液下注不止，主方用桂心茯苓丸。药物均等分制成丸剂，饭前服用一丸。如果效果不明显，增加到三丸。使用桂心、茯苓、牡丹皮、桃仁（炒制），用来消散瘀血，芍药用来保护营血，这样血液才能停止下注而胎儿得以安宁。世传版本作“桂枝茯苓丸”，这是传抄的错误。详细分析桂枝气味轻薄，只能走表发散，必须取肉桂之心，才有去除瘀血的功效。安常认为桂类药材不伤胎，不要怀疑它对妊娠有妨碍。看下一条子脏开泄用附子汤，转胞（膀胱受压排尿困难）用肾气丸，都使用了桂枝、附子，这正是《内经》所说的“有病则病受之，不会伤害正气”的道理。
妊娠六七月时，脉象弦紧表示虚寒。虚弱的阳气浮散于外，导致发热。阴寒之气内逆，导致胎胀腹痛。怕冷的原因是体内没有阳气。子脏（子宫）不能执行闭藏的功能，所以感觉阴道内有寒气习习而来，少腹部像被扇子扇风一样冷。使用附子汤来温暖子宫，胎儿自然安宁。张仲景使用附子来安胎，如果不是神明般透彻理解医理的人，不敢轻易尝试。原方缺失，可以根据医理推测，必定包含干姜、肉桂这类药物。
行经与结胎，都属于冲脉和任脉的功能。冲任二脉虽然主持阴阳交合，由肝肾功能所主导，但是长养形成胎儿，又依赖于脾胃（坤土）。因为阴阳相互包容抱持就不会泄漏，脾胃堤防坚固就不会渗漏。如果有宿存的瘀浊邪气客居于冲任二脉，那么阴血就会自相结聚，不能与阳气交合，所以有时会出现漏下、半产（流产）、下血不绝等症状。凡是妊娠期间的胎气，是由阳精在内构成，阴血在外滋养。现在阴血自相结聚，与胎儿阻隔，不能相互调和，独阴在内，导致腹中疼痛、下血，这都是阴阳失去相互包容、脾胃失去堤防作用的结果，主方用胶艾汤。该方的组成：川芎二两，当归三两，宣通阳血；白芍四两，干地黄四两，宣通阴血；阿胶二两，属于血肉有情之品，同类相求以滋养，安胎补血，堵塞漏泄；甘草二两，缓和急迫，调和阴阳，疏通血脉；艾叶二两，专门调理湿郁导致的带下和漏下病症。此方药力内入，开通阴血的结滞并与阳气相通，具有调经止漏、安胎养血的妙用。然而加减用药必须根据情况适宜，如果脉象迟缓，阴盛于阳，则加干姜；如果脉象数大，阳盛于阴，则加黄芩，这可以不言而喻。
孕妇有的因为脾土被肝木邪气克制，谷气不能升举，湿气淫溢下流阻滞阴血，导致腹中绞痛，主方用当归芍药散。这与胎气阻滞引起的疼痛不同，所以重用芍药一斤作为君药，以泻肝气、利滞涩；佐以川芎、当归各三两，补血止痛；茯苓四两，泽泻半斤，渗湿降浊从小便排出；白术四两，健脾燥湿。要知道内外六淫邪气，都能损伤胎儿导致疼痛，不仅仅是湿气。
孕妇先前因为脾胃虚弱，津液停留，蓄积成为痰饮。到了妊娠两个月之后，浊阴之气上冲，中焦不胜其逆，痰饮于是涌动，中焦寒起，呕吐不止，主方用干姜人参半夏丸。这就是世俗所谓的恶阻病。所以使用干姜一两以止寒，人参一两以补虚，制半夏二两以治痰散逆，并用生姜汁和丸，每次饮服十丸，每日三次。
孕妇小便困难的，是因为膀胱热郁，气机结成燥结，病不在中焦而在下焦，所以饮食正常，主方用归母苦参丸。每味药各四两，制成如小豆大小的丸剂，每次饮服三丸，增加到十丸。此方中当归调和血液润燥，贝母清肺开郁，苦参擅长治疗热证，利窍逐水，配合贝母并入膀胱，以清除热结，结通则水液运行了。
孕妇小便不利，病位在膀胱。膀胱内部连接胞室，主要贮藏津液，通过气化作用排出尿液，外部联系经脉，上行至头部，是诸阳经的体表。现在膀胱气化功能失常，尿液无法排出，外部不能滋润经脉，所以身体沉重、洒淅恶寒，起身即头晕目眩。只要通利小便，水去则经气运行，表证自愈，主方用葵子茯苓散。冬葵子一斤，直入膀胱，以通利癃闭；佐以茯苓三两，以渗利水道，小便通利，各种病症痊愈。
凡是妊娠的妇女，精气留存、血液包裹，尺脉搏动明显，脉搏跳动则产生生命变化。如果静止不动，则不生发变化。因此妊娠的血不可以静止，静止则凝滞，凝滞则不生发变化而亏少，亏少则虚，都不能与化生胎儿的火（命门之火/阳气）相合。要知道胎孕的生发变化，必须有脉搏的动搏，所以调理的方法，先调和阴阳，疏通气血，常服用养胎的药物，不仅安胎易产，而且能免除产后各种疾病，宜常服用当归散，用酒送服。使用川芎、当归、白芍各一斤，安胎补血。白术半斤，去除腰脐间的陈旧瘀血，补胃养胎，对于因寒湿滞留的胎外之血，都能化解。黄芩一斤，转化壮火回归少火以生气，所以作为常服之剂。但是应当根据脉证迟数虚实进行加减，有病则服，没病则不必服用。药味偏颇而不中正，不像米谷那样平和，岂适合无病久服。经文说：“味道进入体内，各自归于其所喜攻的组织，气味长期偏胜，是折寿的原因。”
凡是妊娠血液聚集而后形成胎儿，稍微遇到邪气，所聚集的血液就会停滞不运，反而类似瘀恶之物，必须先破除旧的瘀血生成新的血液，然后胎儿才可养育。养胎不仅在于血，而且胎儿系于肾，养育又在于胃，所以补肾调胃，补肾以固摄精气，调胃以调和中焦，主方用白术散。但是白术散方中只有四味药，本草书都说能去恶血，为什么用于养胎呢？大概白术三分能调胃；蜀椒三分（出汗，另一版本作秦椒）开通痹阻，痹阻开通则阳精到达；牡蛎四分治疗崩漏，崩漏停止则阴精稳固；川芎三分下行入血海，运动胎血，破旧生新。如果阴血不利，肝木为害，在内压抑屈曲而疼痛的，用芍药的酸寒来泻之，以通其阴。如果气直冲过剧而疼痛的，用川芎的辛温来散之，以通其阳。或者夹杂瘀恶之气上逆于胃，导致胃中吐烦不能进食的，用细辛温中去痰下气，半夏治疗心下急痛，和胃进食，止吐逆。如果呕吐不止，是由于肝木妄动，用小麦饮养护其本气以安定它，并且又能平胃下气止烦，一举两得。大麦主消渴益气调中，所以中气不足而口渴的用它。
In general, if a woman's pulse shows no obvious pathological signs, but only the Yin pulse (Chi pulse at the wrist) is small and weak, this indicates a deficiency of Ying Qi (Nutritive Qi). If external pathogens are contracted while Ying Qi is deficient, there will inevitably be aversion to cold and fever. Since there is currently neither aversion to cold nor fever, but rather difficulty with food intake (poor appetite), it can be known that she is pregnant. Menstruation ceases; by the sixtieth day, blood gathers and Qi struggles, beginning to condense into a fetus. Ying Qi converges on the fetal origin, leading to insufficient Stomach Qi and reduced distribution of body fluids; thus, the person experiences thirst and inability to eat. It is appropriate to use Guizhi Tang (Cinnamon Twig Decoction) to harmonize Ying and Wei (Defensive Qi) and benefit the Stomach Qi. If physicians treat this as other diseases, exacerbating vomiting and diarrhea, this condition is called Ezu (Morning Sickness/Pregnancy Vomiting); medical intervention should cease, waiting for self-recovery. (Guizhi harmonizes Ying and disperses pathogens; paired with Shaoyao to astringe Yin; Gancao moderates the action; guided by Shengjiang and Dazao, the pungent-sweet warm-natured herbs move Spleen fluids to harmonize Ying and Wei, stopping thirst.)
Whenever women encounter cold during menstruation, residual blood stagnates forming Blood Stasis. However, women with Blood Stasis are common; if the stasis does not obstruct the uterus, menstruation may continue and conception can occur. Although blood gathers to form a fetus, menstruation stops only after three months of fetal formation. Before three months have passed since cessation, if the Blood Stasis pathology reactivates, it leads to continuous spotting or bleeding. The stasis resides in the Lower Jiao, pressing on the fetus, hence termed "Guhai" (Chronic/Fixed Pathology). Therefore, movement felt above the umbilicus, confirmed upon inquiry, indicates a normal pregnancy. A "Ghost Fetus" (hydatidiform mole or abnormal gestation) belongs to Yin Qi aggregation and would absolutely not exhibit Yang activity in Yang positions (above the umbilicus). Current movement above the umbilicus indicates the fetus is six months old. It is inferred that although menstruation was regular for the first three months, the fetus had already formed; for the subsequent three months, menstruation ceased, but blood accumulated into stasis, causing continuous downward bleeding. The primary formula is Guixin Fuling Wan (Cinnamon Heart and Poria Pill). Herbs are equal parts made into pills, taken one pill before meals. If ineffective, increase to three pills. Uses Guixin (Cinnamon Heart), Fuling (Poria), Mudanpi (Moutan Cortex), and Taoren (Peach Seed, stir-fried) to dissipate stasis; Shaoyao protects Ying blood; thus bleeding stops and the fetus is secured. The version circulating in世的 as Guizhi Fuling Wan is a transcription error. Detailed analysis shows Guizhi has thin aroma and flavor, suitable only for releasing the exterior; one must use the heart of Rougui (Cinnamon Bark) to have the efficacy of removing stasis. An Chang stated that Cinnamon does not harm the fetus; do not doubt its safety in pregnancy. Referencing the next section where Fuzi Tang is used for an open Zang Zang (uterus) and Shenqi Wan for Zhuanbao (bladder compression/difficulty urinating), both utilize Guizhi and Fuzi; this aligns with the Nei Jing principle: "If there is a disease, the disease receives the treatment without injury [to the healthy qi]."
During the sixth or seventh month of pregnancy, a wiry pulse indicates deficiency-cold. Deficient Yang scatters outward, causing fever. Internal reversal of Yin-Cold causes abdominal distension and pain due to the fetus. Aversion to cold indicates the interior lacks Yang. The Zi Zang (Uterus) fails to execute its closing and storing function, so there is a sensation of cold air blowing from the vagina, and the lower abdomen feels like it is being fanned. Use Fuzi Tang to warm the Zang Zang, ensuring fetal security. Zhang Zhongjing’s use of Fuzi for calming the fetus requires divine understanding; few dare to try lightly. The original formula is missing, but can be inferred to likely contain Ganjiang (Dried Ginger) and Guixin/Rougui (Cinnamon).
Menstruation and conception both belong to the Chong and Ren Mai (Penetrating and Conception Vessels). Although Chong and Ren manage Yin-Yang intersection via Liver and Kidney functions, nourishing and forming the fetus relies on Kun Tu (Spleen/Stomach Earth). Because Yin and Yang embrace each other, leakage is prevented; Kun Tu acts as a dike, preventing seepage. If chronic turbid stasis lodges in Chong and Ren, Yin blood binds internally and cannot intersect with Yang, leading to occasional spotting, miscarriage, or continuous bleeding. Pregnancy Qi consists of Yang Essence formed internally and Yin Blood nourishing externally. Now, if Yin Blood binds internally, blocking the fetus and preventing harmony, solitary Yin remains inside, causing abdominal pain and bleeding. This results from Yin-Yang failing to embrace and Kun Tu failing to dike. The primary formula is Jiao Ai Tang (Donkey-Hide Gelatin and Mugwort Decoction). Composition: Xiong 2 liang, Gui 3 liang to circulate Yang blood; Shaoyao 4 liang, Dihuang 4 liang to circulate Yin blood; Ejiao 2 liang, a substance of flesh and blood, nourishes similarly, calms fetus, tonifies blood, and seals leakage; Gancao 2 liang, moderates urgency, harmonizes Yin-Yang, unblocks vessels; Aiye 2 liang, specifically treats dampness-stagnation with leukorrhea and spotting. This formula enters internally, opens Yin blood binding to connect with Yang, offering wonders of regulating menses, stopping spotting, calming fetus, and nourishing blood. Additions/subtractions must be appropriate: if pulse is slow/late indicating Yin excess over Yang, add Ganjiang; if pulse is rapid/large indicating Yang excess over Yin, add Huangqin.
Some pregnant women suffer because Spleen Earth is overcome by Liver Wood evil, grain Qi fails to rise, dampness floods downward stagnating Yin blood, causing abdominal cramping pain. Primary formula: Danggui Shaoyao San (Angelica and Peony Powder). This differs from pain caused by fetal obstruction. Thus, Shaoyao (1 jin) is the Sovereign herb to drain Liver and relieve stagnation; assisted by Xiong and Gui (3 liang each) to tonify blood and stop pain; Fuling (4 liang) and Zexie (8 liang) to leach dampness down via urine; Baizhu (4 liang) to benefit Spleen and dry dampness. Know that external and internal Six Evils can all damage the fetus causing pain, not just dampness.
Pregnant women previously suffering from Spleen-Stomach weakness retain body fluids, accumulating as Phlegm-Fluids. After two months of pregnancy, turbid Yin rushes upward; the Middle Jiao cannot withstand the rebellion, Phlegm-Fluids surge, Middle Cold arises, and vomiting persists. Primary formula: Ganjiang Renshen Banxia Wan (Dried Ginger, Ginseng, and Pinellia Pill). This is the secular "Ezu" (Morning Sickness). Uses Ganjiang (1 liang) to stop cold, Renshen (1 liang) to tonify deficiency, Banxia (2 liang, processed) to treat phlegm and scatter rebellion, formed into pills with Shengjiang juice, taken ten pills per dose, three times daily.
Difficulty in urination during pregnancy is due to Bladder Heat stagnation, Qi condensing into dryness. The disease is in the Lower Jiao, not Middle, so diet is normal. Primary formula: Guimu Kushen Wan (Danggui, Motherwort, and Sophora Pill). Each herb 4 liang, pills sized like beans, take 3 pills, increase to 10. Danggui harmonizes blood and moistens dryness; Beimu clears Lung and opens depression; Kushen excels at treating heat, benefiting orifices and driving out water; assisting Beimu entering the Bladder to remove heat knots; once knots clear, water flows.
Urinary difficulty/inability during pregnancy locates in the Bladder. Internally connected to the Bao Shi (Uterus), it stores fluids and excretes urine via Qi transformation. Externally connects to meridians, ascending to the head, serving as the exterior of all Yang meridians. Now Bladder Qi fails to transform, urine cannot exit, exterior meridians are not benefited, causing heavy body, chills/shivering, and dizziness upon rising. Only by promoting urination does water leave, meridian Qi moves, and exterior symptoms heal. Primary formula: Kuizi Fuling San (Malva Seed and Poria Powder). Kuizi (1 jin) enters Bladder directly to relieve retention; assisted by Fuling (3 liang) to leach water pathways; once urination is smooth, all diseases resolve.
For pregnant women, essence remains and blood wraps; the Chi pulse pulses visibly. Movement generates change/life. Stillness produces no change. Therefore, pregnancy blood must not be static; static blood coagulates, coagulated blood fails to generate/nourish, becoming deficient. Deficiency cannot combine with the Fire that transforms the fetus. Fetal generation requires pulsing arteries. Regulation involves first harmonizing Yin-Yang and benefiting Qi-Blood. Regularly taking fetal-nourishing herbs ensures easy delivery and prevents postpartum diseases. Recommended regular use of Danggui San (Angelica Powder), taken with wine. Xiong, Gui, Shaoyao (1 jin each) calm fetus and tonify blood. Baizhu (0.5 jin) removes old stasis around waist/navel, benefits Stomach and nourishes fetus, resolving external fetal blood stagnated by cold-damp. Huangqin (1 jin) transforms vigorous fire back to mild fire to generate Qi, making it suitable for regular use. However, additions/subtractions must follow pulse/symptoms (slow/fast, deficiency/excess). Take when diseased, not otherwise. Herbs are biased/unbalanced, unlike rice/grain; unsuitable for long-term use without disease. The Classic states: "Flavors enter and target their preferred organs; prolonged excessive Qi intake causes premature death."
After pregnancy blood gathers to form a fetus, slight pathogenic invasion causes stagnant blood to fail to circulate, resembling bad stasis. One must first eliminate old stasis to generate new blood before the fetus can be nourished. Nourishing the fetus depends not only on blood but also on the Kidneys (where the fetus is rooted) and the Stomach (which nurtures). Thus, tonify Kidneys to secure Essence, regulate Stomach to harmonize the Middle. Primary formula: Baizhu San (Atractylodes Powder). Why use herbs known to remove bad blood? Baizhu (3 fen) regulates Stomach; Shujiao (3 fen, induces sweating, some texts say Qinjiao) opens Bi (obstruction); once opened, Yang Essence arrives; Muli (4 fen) treats Bing (flooding); once stopped, Yin Essence secures; Chuanxiong (3 fen) descends to Blood Sea, moves fetal blood, eliminates old to generate new. If Yin blood is unfavorable and Liver Wood harms, causing internal suppression/pain, drain with Sour-Cold Shaoyao to unblock Yin. If direct rushing causes pain, disperse with Acrid-Warm Xiong to unblock Yang. If mixed with bad Qi rebels to Stomach causing vomiting/restlessness/anorexia, use Xixin to warm middle, descend Qi, resolve phlegm; Banxia treats epigastric urgency, harmonizes Stomach, promotes eating, stops vomiting. If vomiting persists due to reckless Liver Wood movement, use Xiaomai Yin (Wheat Drink) to nourish original Qi and calm it, simultaneously calming Stomach, descending Qi, and stopping restlessness—killing two birds with one stone. Damai (Barley) treats thirst, benefits Qi, harmonizes middle; used for middle Qi deficiency with thirst.
