冠，此方分两出《必用方》以此为正。一方枳壳六两，甘草一两。（故加枳壳，减甘草，盖
未产人甘草性寒故，而未产前一月，日可三服，忌登高厕。）一方有糯米半升，淘洗控干，同炒为
末，米饮或白汤调下一二钱。温隐居加当归、木香各等分。

许学士云∶大率妇人妊娠，唯在抑阳助阴。《素问》云∶阴搏阳别，谓之有子。盖关
前为阳，关后为阴，尺中之脉，按之搏手不绝者，妊身也。妇人平居，阳气微盛无害，及
其妊子，则方闭经隧以养胎，若阳气盛，搏之则经脉妄行，胎乃不固，《素问》所谓阴虚
阳搏，谓之崩也。抑阳助阴之方甚多，然胎前药唯恶群队，若阴阳交错，别生他病，唯
是枳壳散所以抑阳，四物汤所以助阴故尔。然枳壳散差寒，若单服之恐有胎寒腹痛之疾，以
内补丸佐之，则阳不致强，阴不致弱，阴阳调停，有益胎嗣，此前人未尝论及也。

勤于针指，构思旬日，忽自悟曰∶此正与湖阳公主相反。彼奉养之人，其气必实，耗其
气使平和故易产。今形肥知其气虚，久坐知其不运，必气愈弱，儿在胞胎，因母气不能
自运耳，当补其母之气，则儿健易产矣。令其有孕至五六个月来告，遂于《大全》方紫
苏饮加补气药与数十帖，因得男而甚快，后遂以此方随母形色性禀，参时令加减与之，无

**滑胎枳壳散**：具有使胎儿瘦小、易于分娩的功效。湖阳公主每次生产都历经多日胎儿无法娩出，南山道士进献此方。
药材及用量：商州产的枳壳（二两），粉草（一两）。
制法与用法：将上述药物研成细末，用滚开水冲服二钱，空腹服用，每日三次。凡怀孕七八个月以上者服用，可使胎儿容易出生。初生时胎儿体型微小且肤色微黑，百日之后，逐渐变白。这虽然是孙思邈真人（孙真人）的滑胎易产方，但其功效在于抑制阳气、降下气机，在众多方剂中居于首位。本方的剂量出自《必用方》，以此为准。另一版本方剂中枳壳用六两，甘草用一两。（因为未生产前，甘草性寒，所以增加枳壳用量，减少甘草用量。在未产前一个月，每日可服三次，忌登高或去厕所。）还有一方加入糯米半升，淘洗后控干水分，与药同炒后研为细末，用米汤或白开水调服一二钱。温隐居在此方基础上加入当归、木香各等分。
**张氏方**：治疗妊娠期间胎儿过大导致子宫空间狭窄，孕妇行动起居艰难，临产前服用，可缩小胎儿体积，便于分娩。兼治肠道各种疾病，具有下气宽胸膈的作用。
药材及用量：枳壳（五两），甘草（一两半），香附子（三两，炒制并去除毛须）。
制法与用法：研为细末，可用生姜煎汤冲服亦可。如果是丈夫或妇人因冷气攻刺导致胁肋疼痛者，用三寸长的葱白同煎服用。妇人脾脏虚寒，气血凝结成块引起疼痛者，用热酒调服。大小便不通者，用白牵牛子粉末煎汤调服。《选奇方》中的配方为：香附子、枳壳（各二两），甘草（半两）。
**内补丸**：治疗孕妇冲脉和任脉虚弱，具有补血安胎的功效。
药材及用量：熟地黄（二两），当归（微炒，一两）。
制法与用法：研为细末，用炼蜜调和制成如梧桐子大小的丸药，用温酒送服三四十丸。
许学士说：大抵妇女妊娠，关键在于抑制阳气、辅助阴气。《素问》说：“阴脉搏动而阳气有别，称为有孕。”大概关前部位属阳，关后部位属阴，尺部脉象按之搏动有力、连绵不绝者，即为怀孕。妇女平时居住，阳气略微旺盛并无害处，但等到怀孕生子时，身体正封闭经隧以滋养胎儿，如果阳气过盛，搏击经脉则会导致经脉妄行，胎儿就不稳固，《素问》所谓“阴虚阳搏，称为崩漏”。抑制阳气、辅助阴气的方剂很多，然而产前用药唯独忌讳杂乱无章的药物堆砌，如果阴阳交错，会生出其他疾病。唯有枳壳散能抑制阳气，四物汤能辅助阴气，所以如此。但是枳壳散药性偏寒，如果单独服用恐怕会导致胎寒腹痛的疾病，配合内补丸来辅助，则阳气不至于过强，阴气不至于过弱，阴阳调和，有利于胎儿发育，这是前人未曾论述过的。
**易产滑胎散**：其药性滑利，通利小便。
用法：用车前子（研为粉末），用酒调服一方寸匕的量，不能饮酒者用水调服。
《诗经》说：“采采莬丝，能让妇人乐于拥有子女。”陆机注解说：“这是治疗妇人难产的缘故。”
**神寝丸**：使胎儿瘦小、滑利、易于分娩，临产前一个月服用，极有神效。此方源自蕲州施少卿，由蕲州徐太丞传授。
药材及用量：通明乳香（另研细，半两），枳壳（一两）。
制法与用法：研为细末，用炼蜜制成如梧桐子大小的丸药，空腹用温酒吞服三十丸，怀孕九个月以后方可服用。《崔氏方》名为寐生丸，乳香只用二钱半，用酒糊制作丸药。
**榆白皮散**：治疗妊娠滑胎、易于分娩。
药材及用量：榆白皮，甘草（各二两），葵子（一两）。
制法与用法：研为粗末，每次服用二钱，加水一盏，煎至七分，去渣滓温服。另一版本没有榆皮，名为葵子散。主要用于怀孕九个月，即将分娩时的调理。
**食疗方**：猪肚（一个完整的）。按照方法用葱和五味调料煮熟食用，如果吃不完，再吃，直到吃完为止。不得给别人吃，否则无效。
**保气饮**：安胎、宽顺气机、增进食欲，使胎儿瘦小、易于分娩。假如居住不当，偶然跌倒，导致胎动胎痛、漏胎下血，兼服佛手散（见胎产大法）、神寝丸、枳壳散（均见上文）。这三方，在入月（临产前一个月）内非常适宜常服。
药材及用量：香附子（四两），山药（二两），缩砂仁（一两），粉草（一两二钱半），益智仁，紫苏叶（各半两），木香（四钱）。
制法与用法：研为细末，用白开水冲服二钱。
**无忧散**：治疗妊娠期间身居富贵之家，口中厌倦肥甘厚味，情绪忧喜无常，饮食不节制，吃饱后就躺卧，导致胞胎肥厚浓重，根基坚牢，行动艰难，因而导致临产时难以分娩。入月后可服用无忧散，则容易分娩了。
药材及用量：当归，川芎，白芍药，枳壳，乳香（各三钱），木香，甘草，血余（即头发灰，用猪心血调和，各一钱半）。
制法与用法：研为细末，每次服用二钱，水煎，每日服用两次。
朱丹溪说：世间的难产者，往往出现在郁闷安逸的人身上，富贵豢养的家庭里，贫贱辛苦的人家却没有这种情况。古方书中只有瘦胎饮这一理论，而其方是为湖阳公主所作，确实不是极致的言论。为什么呢？见到有人使用此方，其难产情况依然如故。我的表妹苦于难产，后来遇到怀孕，就触怒而流产，我很怜悯她。观察她的形体，只是勤于针线女红，构思了十几天，忽然自己领悟道：“这正好与湖阳公主的情况相反。”那些奉养优渥的人，其气必然实，消耗其气使其平和所以容易分娩。现在看她形体肥胖，知道其气虚，久坐不动知道其气不运行，必定气更弱，胎儿在胞胎中，因为母体之气不能自行推动所致，应当补益母亲的气，那么胎儿健壮就容易分娩了。让她怀孕到五六个月时来告知，于是从《大全》方中的紫苏饮加入补气药给予几十帖，因此顺利生下男孩且很高兴，后来便以此方根据母亲的形色性格禀赋，参考时令加减给予服用，没有不应验的，因此将此方命名为达生散。
**缩胎饮**（即达生散）。
药材及用量：大腹皮（三钱），人参，陈皮，紫苏茎叶（各五分），白芍，白术，归身尾（各一钱），甘草（二钱，炙），黄杨树脑（七个），或者加枳壳、缩砂、青葱（五叶）。
制法与用法：作一帖药量，吞服益母丸，临产前得到二十帖的药量即可容易分娩，产后无病。
按语：丹溪说：难产死胎，这是血气滞涩的病证。
大概此方能补中焦并消除滞涩。春季加川芎。气虚加倍用人参、白术。气实加倍用香附、陈皮。血虚加当归、地黄。形体实加倍用紫苏。性情急躁加黄连。热急加黄芩。湿痰加滑石、半夏。食积加山楂。饭后易饥加黄杨脑。腹痛加木香、官桂、黄芩。冬季不用黄芩。
**黑神丸**（一名催生丸，一名益母丸）。用益母草研末，用米粥制作丸药，治疗妇人临产前，一日三次服用，用缩砂饮送下，能催生易产。产后服用，能生成新血，去除旧血，只用白开水送下。体虚者用白术、人参、陈皮煎汤送下。
**Huatai Zhike San (Slippery Fetus Bitter Orange Powder)**: It has the effect of making the fetus slender and facilitating delivery. Princess Huyang experienced multiple days of labor with the fetus failing to descend during each birth, until a Daoist priest from Nanshan presented this prescription.
Ingredients and Dosages: Zhike (Bitter Orange Fruit) sourced from Shangzhou (2 liang), Fencao (Licorice Root) (1 liang).
Preparation and Administration: Grind the above ingredients into a fine powder. Take 2 qian mixed with boiling water. Consume on an empty stomach, three times daily. For those pregnant for seven or eight months or more, taking this will facilitate the birth of the fetus. The newborn will initially be small in size and slightly dark-skinned, gradually turning white after one hundred days. Although this is Sun Simiao's (Sun Zhenren) prescription for slippery fetus and easy delivery, its efficacy lies in suppressing Yang Qi and descending Qi, ranking it among the best of many prescriptions. The dosages of this prescription are based on *Bi Yong Fang* (Prescriptions Essential for Use), which is considered the standard. Another version uses 6 liang of Zhike and 1 liang of Gancao. (Gancao is cold in nature before childbirth; thus, Zhike is increased and Gancao is decreased. In the month prior to delivery, it can be taken three times daily, but one should avoid climbing high places or using toilets.) Another variation adds 0.5 sheng of glutinous rice, washed and drained, stir-fried together with the herbs, then ground into powder. Take 1-2 qian mixed with rice water or plain boiled water. Wen Yiju added Danggui (Angelica Sinensis) and Muxiang (Aucklandia Root) in equal proportions.
**Zhang Shi Fang (Master Zhang's Prescription)**: Treats pregnancy where fetal overgrowth causes uterine constriction, leading to difficulty in movement and daily activities. Taken near term, it reduces fetal size to facilitate delivery. It also treats various intestinal diseases, descending Qi and widening the chest diaphragm.
Ingredients and Dosages: Zhike (Bitter Orange Fruit) (5 liang), Gancao (Licorice Root) (1.5 liang), Xiangfuzi (Cyperi Rhizoma) (3 liang, stir-fried and de-husked).
Preparation and Administration: Grind into powder. Can be taken mixed with ginger decoction. For husbands or wives suffering from piercing pain in the hypochondrium due to cold Qi, boil with 3 cun of scallion white and take. For women with spleen-cold and blood-Qi stagnation forming masses causing pain, take mixed with hot wine. For urinary and fecal obstruction, take mixed with decoction of Baiqianniu (White Morning Glory Seed) powder. The formula in *Xuan Qi Fang* consists of: Xiangfuzi (Cyperi Rhizoma), Zhike (Bitter Orange Fruit) (2 liang each), Gancao (Licorice Root) (0.5 liang).
**Neibu Wan (Internal Tonifying Pill)**: Treats deficiency of the Chong and Ren meridians in pregnant women, nourishing blood and calming the fetus.
Ingredients and Dosages: Shudihuang (Prepared Rehmannia Root) (2 liang), Danggui (Angelica Sinensis) (lightly stir-fried, 1 liang).
Preparation and Administration: Grind into fine powder. Mix with refined honey to form pills the size of wet wax tree seeds. Take 30-40 pills with warm wine.
Scholar Xu stated: Generally, for pregnant women, the key lies in suppressing Yang Qi and assisting Yin Qi. *Suwen* states: "When the Yin pulse beats distinctly while the Yang is separate, it indicates pregnancy." Roughly speaking, the area anterior to the Guan position belongs to Yang, and the area posterior belongs to Yin. If the pulse at the Chi position feels vigorous and unceasing upon pressure, it indicates pregnancy. When women are at rest, slight excess of Yang Qi is harmless. However, during pregnancy, when the body closes the meridian tunnels to nourish the fetus, if Yang Qi is excessive and attacks the meridians, it causes erratic meridian flow, making the fetus unstable. As *Suwen* says: "Yin deficiency with Yang pounding leads to metrorrhagia." There are many prescriptions to suppress Yang and assist Yin, but prenatal medications should strictly avoid chaotic combinations of herbs. If Yin and Yang are mixed indiscriminately, other diseases may arise. Only Zhike San suppresses Yang, and Siwu Tang assists Yin. However, Zhike San is slightly cold; taking it alone might cause fetal coldness and abdominal pain. By combining it with Neibu Wan, Yang will not become too strong, and Yin will not become too weak. This harmonization of Yin and Yang benefits the offspring, a point previously unmentioned by predecessors.
**Yichan Huatai San (Easy Delivery Slippery Fetus Powder)**: Its medicinal properties are slippery and promote urination.
Administration: Take Cheqianzi (Plantago Seed) powder mixed with wine, one fangcun bi (a measure equivalent to a square inch spoonful). For those who cannot drink alcohol, mix with water.
The *Classic of Poetry* states: "Gathering Euphorbia lathyris allows women to joyfully bear children." Lu Ji's annotation explains: "This is used to treat difficult labor in women."
**Shenqin Wan (Divine Sleep Pill)**: Makes the fetus slender, slippery, and easy to deliver. Take it in the month before delivery; it is extremely effective. This prescription originated from Vice Prefect Shi of Qizhou and was transmitted by Grand Attendant Xu of Qizhou.
Ingredients and Dosages: Tongming Ruxiang (Frankincense) (separately ground, 0.5 liang), Zhike (Bitter Orange Fruit) (1 liang).
Preparation and Administration: Grind into powder. Mix with refined honey to form pills the size of wet wax tree seeds. Swallow 30 pills with warm wine on an empty stomach. Can only be taken after the ninth month of pregnancy. The *Cui Shi Fang* names this Meisheng Wan, using only 2.5 qian of Ruxiang, made into pills with wine paste.
**Yubai Pi San (Elm Bark Powder)**: Treats pregnancy, promoting slippery fetus and easy delivery.
Ingredients and Dosages: Yubai Pi (Ulmus Cortex) (2 liang), Gancao (Licorice Root) (2 liang), Kuizi (Abelmoschus Manihot Seed) (1 liang).
Preparation and Administration: Grind into coarse powder. Take 2 qian per dose, add one zhan of water, decoct until reduced to 0.7 zhan, remove dregs, and take warm. Another version without Elm Bark is named Kuizi San. It is mainly used for conditioning in the ninth month of pregnancy, approaching delivery.
**Dietary Therapy**: One whole pig stomach. Cook thoroughly with scallions and five spices according to method. Eat until finished. If not finished, eat again until consumed. Do not give to others, or it will be ineffective.
**Baoqi Yin (Qi-Preserving Decoction)**: Calms the fetus, regulates Qi, promotes appetite, makes the fetus slender, and facilitates delivery. If improper living conditions lead to accidental falls, causing fetal movement, fetal pain, or threatened miscarriage with bleeding, concurrently take Foshe San (see Major Principles of Obstetrics and Gynecology), Shenqin Wan, and Zhike San (all see above). These three prescriptions are highly suitable for regular consumption in the month before delivery.
Ingredients and Dosages: Xiangfuzi (Cyperi Rhizoma) (4 liang), Shanyao (Dioscorea Rhizome) (2 liang), Suosharen (Amomum Fructus) (1 liang), Fencao (Licorice Root) (1.25 liang), Yizhiren (Alpinia Oxyphylla Fruit), Ziye (Perilla Leaf) (0.5 liang each), Muxiang (Aucklandia Root) (0.4 liang).
Preparation and Administration: Grind into powder. Take 2 qian mixed with plain boiled water.
**Wuyou San (Carefree Powder)**: Treats pregnancies in wealthy individuals who are accustomed to rich and sweet foods, experience emotional instability, have irregular eating habits, lie down immediately after full meals, resulting in thick and heavy fetal membranes, firm anchoring, and difficult movement, leading to difficult labor at term. Taking Wuyou San in the month before delivery facilitates birth.
Ingredients and Dosages: Danggui (Angelica Sinensis), Chuanxiong (Ligusticum Rhizome), Baishaoyao (White Peony Root), Zhike (Bitter Orange Fruit), Ruxiang (Frankincense) (3 qian each), Muxiang (Aucklandia Root), Gancao (Licorice Root), Xueyu (Hair Ash, mixed with pig heart blood) (1.5 qian each).
Preparation and Administration: Grind into powder. Take 2 qian per dose, decoct with water, take twice daily.
Zhu Danxi said: Difficult births often occur in people who are depressed and idle, specifically in families raised in luxury. They are rarely seen in poor and hardworking families. Ancient medical texts only discuss the theory of Shoutai Yin (Slimming Fetus Decoction), and its prescription was created for Princess Huyang, which is indeed not the ultimate truth. Why? Because I have seen people use this prescription, yet they still experience difficult labor. My cousin suffered greatly from difficult labor; later, whenever she became pregnant, she would induce abortion out of fear, which deeply pitied me. Observing her physique, she was diligent in needlework. After pondering for ten days, I suddenly realized: "This situation is exactly opposite to that of Princess Huyang." Those with luxurious lifestyles must have robust Qi; consuming their excess Qi brings balance, hence easy delivery. Now, seeing her obese physique indicates Qi deficiency, and prolonged sitting indicates stagnant Qi circulation, meaning her Qi is even weaker. The fetus in the womb relies on the mother's Qi for movement; therefore, we should tonify the mother's Qi so the fetus becomes strong and delivers easily. She came to report when pregnant for five to six months. I took the Zisu Yin (Perilla Decoction) from *Daquan Fang* (Complete Prescriptions), added Qi-tonifying herbs, and administered dozens of doses. She subsequently gave birth to a healthy boy with great joy. Later, I adjusted this prescription based on the mother's physique, temperament, and seasonal changes, achieving consistent success. Thus, I named this prescription Dasheng San.
**Suotai Yin (Fetus-Shrinking Decoction)** (Also known as Dasheng San).
Ingredients and Dosages: Dafupi (Areca Peel) (3 qian), Renshen (Ginseng Root), Chenpi (Tangerine Peel), Zisu Jingye (Perilla Stem and Leaf) (5 fen each), Baishao (White Peony Root), Baizhu (Atractylodes Rhizome), Guishenwei (Angelica Sinensis Root Tip) (1 qian each), Gancao (Licorice Root, honey-fried) (2 qian), Huangyangshunao (Buxus Seed Oil/Extract) (7 units), optionally add Zhike (Bitter Orange Fruit), Suosharen (Amomum Fructus), Qingcong (Green Onion) (5 leaves).
Preparation and Administration: Prepare as one dose. Swallow with Yimu Wan (Motherwort Pill). Obtaining twenty doses before term facilitates delivery, leaving the postpartum period free of illness.
Commentary: Danxi stated: Difficult labor and retained dead fetus are diseases of Qi and Blood stagnation.
Generally, this formula tonifies the Middle Jiao and removes stagnation. Add Chuanxiong in Spring. Double Renshen and Baizhu for Qi deficiency. Double Xiangfu and Chenpi for Qi excess. Add Danggui and Dihuang for Blood deficiency. Double Zisu for robust constitution. Add Huanglian for irritability. Add Huangqin for heat urgency. Add Huashi (Talcum) and Banxia (Pinellia Tuber) for damp-phlegm. Add Shanzha (Hawthorn Fruit) for food stagnation. Add Huangyangnao for postprandial hunger. Add Muxiang (Aucklandia Root), Guirou (Cinnamon Bark), and Huangqin (Scutellaria Root) for abdominal pain. Do not use Huangqin in Winter.
**Heishen Wan (Black Divine Pill)** (Also called Cuisheng Wan [Urging Birth Pill] or Yimu Wan [Motherwort Pill]). Make pills using Motherwort (Yimucao) powder mixed with rice porridge. Treats women near term; take three times daily, delivered with Suosharen Yin. It promotes labor and easy delivery. Postpartum use generates new blood and eliminates old blood; take with plain boiled water. For deficiency, take with decoction of Baizhu, Renshen, and Chenpi.
