催生之药，原因妇人难产不得已而用之也。若平素易产者，时至自生，不必服药。如必欲服，求其快便，
须待产妇腹痛必至腰痛已甚，方是欲产之候，始可用药。顺势推之，自当立下。若只腹痛未甚，儿身尚未欲生，
切不可早服催生之药，强其速生，使儿身不能转胞，则横生倒产，必不免矣。是故生无可催也。所谓催生者，
不过助其气血而利导之耳。然必待临产腹痛已甚，方可用脱花煎少加肉桂（五七分），为最稳最妙，或经日久
产母困倦难生，俱宜服滑胎煎，以助其气血使之速生。若气虚无力艰于传送者，必用独参汤接济其力，皆为催
生要法。若期未至而妄用行气导血之剂，以为催生，亦犹揠宋人之苗耳！

催生药物，是因为妇人难产不得已才使用的。如果平时容易生产的孕妇，到了预产期自然分娩，不必服药。如果一定要服药以求快速顺产，必须等到产妇腹痛剧烈并延伸至腰部时，这才是临产的征兆，此时才可以用药。顺应这种趋势推动胎儿娩出，自然会立刻生下。如果只是腹痛不剧烈，胎儿身体尚未准备娩出，切不可过早服用催生的药物，强行要求速生，导致胎儿无法转动胎位，那么横位或倒位等异常分娩就不可避免了。因此，实际上并没有所谓的“催生”之法。所谓催生，不过是辅助气血运行并引导胎儿娩出罢了。然而必须等到临产腹痛剧烈时，方可使用脱花煎（Cui Sheng Jian, 催生汤）并少量加入肉桂（五至七分），这是最稳妥精妙的办法；或者如果产程日久，产母困倦难以生产，都适宜服用滑胎煎（Hua Tai Jian, 滑胎汤），以辅助气血使其迅速分娩。如果是气虚无力、难以传送胎儿的情况，必须使用独参汤（Du Shen Tang, 人参汤）来补充其力量，这些都是催生的重要方法。如果在预产期未到时就滥用行气活血的药物，以为可以催生，这就像拔苗助长一样愚蠢！
脱花煎
当归（七到八钱或一两） 肉桂 川芎 牛膝（各二钱） 车前子（一钱五分）
用水两钟，煎至七分，温服。
气虚加人参一到二钱；阴虚加熟地黄三到五钱。
滑胎煎
当归 熟地黄（各三钱） 山药（用姜汁炒） 杜仲（炒，各二钱） 枳壳（麸皮炒） 川芎（各七分）
水煎，饭前温服。
体质虚弱者，加人参、白术（蜂蜜炙）各二钱；大便干结多滞涩者，加牛膝一钱。
独参汤
人参（二两，去芦头）
水煎取浓汁，趁热一次性服下，频繁服用，以补接气力。
产房应当保持温度冷暖适宜，如果生产在春夏季节，应当避风；生产在秋冬季节，应当避寒。所以在盛夏时节不可对着风口乘凉而受邪气侵袭，也不宜过热导致产母头痛面赤，更不宜多人喧哗惊慌，热气熏蒸。如果在夏季，应当储备一盆凉水，水变温后更换，以解除暑热。如果在冬季，应当储备一盆炭火，务必使下身温暖，衣被也要加厚。这样才不会受到寒气侵袭，可以避免因胎寒血滞导致的难产隐患。而且产后胎元已落，气血俱虚，感受邪气尤其容易，所以不可以不谨慎！
Decoctions for facilitating delivery are used only out of necessity when a woman experiences dystocia. For those who typically deliver easily, birth occurs naturally at term without the need for medication. If one insists on taking medicine to expedite delivery, it is necessary to wait until the parturient's abdominal pain becomes severe and extends intensely to the lower back; this indicates the onset of labor, at which point medication may be administered. By following the natural momentum, the infant will be delivered promptly. However, if abdominal pain is not yet severe and the fetus is not yet ready to descend, one must absolutely avoid administering delivery-facilitating drugs early on to force rapid birth. Doing so may prevent the fetus from rotating within the uterus, inevitably leading to malpresentations such as transverse or breech presentation. Therefore, there is essentially no such thing as "forcing" delivery. What is termed "facilitating delivery" merely assists *Qi* and blood flow to guide the process. One must wait until labor pains are intense before using Tuohua Decoction (Tuohua Jian) with a small addition of Rougui (Cinnamomi Cortex, 5-7 fen). This is the most secure and effective method. Alternatively, if labor has been prolonged and the mother is exhausted and unable to deliver, Huatai Decoction (Huatai Jian) should be administered to assist *Qi* and blood for swift delivery. In cases of *Qi* deficiency resulting in weakness and difficulty in expelling the fetus, Dushen Decoction (Dushen Tang) must be used to replenish strength; these are all essential methods for facilitating delivery. Using Qi-moving and blood-invigorating agents prematurely, before the due date, under the guise of facilitating delivery, is akin to pulling shoots to help them grow—a futile and harmful act!
Tuohua Decoction (Tuohua Jian)
Danggui (Radix Angelicae Sinensis, 7-8 qian or 1 liang) Rougui (Cinnamomi Cortex) Chuanxiong (Rhizoma Chuanxiong) Niuxi (Radix Achyranthis Bidentatae, 2 qian each) Cheqianzi (Semen Plantaginis, 1.5 qian)
Boil in two zhong of water until reduced to seven-tenths. Take warm.
For *Qi* deficiency, add Renshen (Radix Ginseng), 1-2 qian; for Yin deficiency, add Shudihuang (Radix Rehmanniae Preparata), 3-5 qian.
Huatai Decoction (Huatai Jian)
Danggui (Radix Angelicae Sinensis) Shudihuang (Radix Rehmanniae Preparata, 3 qian each) Shanyao (Rhizoma Dioscoreae, stir-fried with ginger juice) Duzhong (Cortex Eucommiae, stir-fried, 2 qian each) Zhiqiao (Pericarpium Aurantii, bran-fried) Chuanxiong (Rhizoma Chuanxiong, 0.7 qian)
Boil in water. Take warm before meals.
For weak constitution, add Renshen (Radix Ginseng) and Baizhu (Radix Atractylodis Macrocephalae, honey-fried), 2 qian each; for constipation with stagnation, add Niuxi (Radix Achyranthis Bidentatae), 1 qian.
Dushen Decoction (Dushen Tang)
Renshen (Radix Ginseng, 2 liang, remove rhizome)
Boil in water to obtain a concentrated decoction. Drink hot in one dose, and administer frequently to replenish *Qi* and strength.
The delivery room should maintain a temperature that is neither too cold nor too hot. During spring and summer, wind exposure should be avoided; during autumn and winter, cold exposure should be avoided. Thus, in midsummer, one should not cool off by facing drafts to avoid pathogenic invasion, nor should the environment be excessively hot, causing headache and facial flushing in the mother. Furthermore, excessive noise and panic among many people should be avoided, as this generates heat and steams the environment. In summer, a basin of cool water should be kept and replaced when warm to alleviate heat. In winter, a charcoal fire should be kept to keep the lower body warm, and clothing and bedding should be thickened. This prevents invasion by cold pathogens and avoids dystocia caused by fetal coldness and blood stasis. After delivery, the placenta is expelled, and both *Qi* and blood are deficient, making the mother highly susceptible to pathogenic invasion; therefore, utmost caution is required!
