凡妊娠胎元完足，弥月而产，熟落有期，非可催也。所谓催生者，亦不过助其血气而利导之耳。直待临
期，乃可用脱花煎或滑胎煎，随证加减主之。或经日久，产母困倦难生，俱宜服滑胎煎，以助其气血，令儿速
生。
其有气虚无力，艰于传送者，必用独参汤，随多随少，接济其力，皆为催生要法。若期未至而妄用行气导血
等剂，以为催生，亦犹摘方苞之萼，揠宋人之苗耳。
脱花煎（见《新方八阵·因阵》）凡临盆将产者，宜先服此药，催生最佳，并治产难经日或死胎不
下，俱妙。
当归（七八钱或一两） 肉桂（一、二钱或三钱） 川芎 牛膝（各二钱） 车前子（钱半） 红花
（一钱，催生者不用此味亦可）
水二钟，煎八分，热服，或服后饮酒数杯亦妙。若胎死腹中或坚滞不下者，加朴硝三五钱，即下。若气虚
困剧者，加人参随宜。若阴虚者，必加熟地三五钱。
滑胎煎（见滑胎）
独参汤（见崩淋经漏不止）
临盆将产，腹痛已甚，凡催生之药，无如脱花煎，少用肉桂五七分，为最稳最妙；若气虚无力者，加人参
二三钱，虚者任意加用之。
催生若水血下多，子道干涩难出者，宜用滑利之物，如猪脂油、蜜酥油、葱白、葵子、牛乳、滑石、榆
白皮之类以润之，亦济急之法也。
凡是妊娠期间胎元发育完全，满十月分娩，成熟落地自有其时，并非可以强行催生的。所谓“催生”，也不过是辅助产妇的血气并加以引导而已。必须等到临产之时，才可以使用脱花煎或滑胎煎，根据具体证候进行加减后主治。如果经过日子很久，产妇困倦乏力难以生产，都适宜服用滑胎煎，以助益气血，使胎儿迅速娩出。
那些因气虚无力，艰难于传送胎儿的，必须使用独参汤，剂量多少随意，以接济其体力，这都是催生的重要方法。如果预产期未到而胡乱使用行气导血等药剂，自以为是在催生，这就像摘取未开的花苞、拔高宋人田里的禾苗一样（徒劳且有害）。
脱花煎（见《新方八阵·因阵》）：凡是临近分娩将要生产的，适宜先服用此药，催生效果最佳，并且治疗难产经日或死胎不下，都非常灵妙。
当归（七八钱或一两） 肉桂（一、二钱或三钱） 川芎 牛膝（各二钱） 车前子（钱半） 红花（一钱，若是为了催生，不用这味药也可以）
用水两钟，煎至八分，热服，或者服药后再喝几杯酒也很好。如果是胎死腹中或坚硬停滞不下的，加入朴硝三五钱，即可排出。如果是气虚极度困倦的，加入人参随宜。如果是阴虚的，必须加入熟地三五钱。
滑胎煎（见滑胎条目）
独参汤（见崩淋经漏不止条目）
临近分娩将要生产时，腹痛已经非常剧烈，凡是用以催生的药物，没有比得上脱花煎的，少用肉桂五七分，是最稳妥最奇妙的；如果是气虚无力的，加入人参二三钱，体虚者任意加用。
如果催生过程中羊水血液流出过多，导致产道干涩难以娩出的，适宜使用滑利的物品，如猪脂油、蜜酥油、葱白、葵子、牛乳、滑石、榆白皮之类来润滑，这也是救急的方法。
Whenever the fetal origin is complete during pregnancy, delivery occurs after ten full months, and ripening and falling have their appointed time; it cannot be induced artificially. What is referred to as "inducing labor" merely assists the blood and qi (vital energy) and facilitates guidance. One should wait until the moment of delivery to administer Tuohua Decoction or Huatai Decoction, modifying them according to the syndrome for treatment. If the duration has been prolonged and the mother is exhausted and unable to deliver, it is appropriate to take Huatai Decoction to assist blood and qi, enabling the child to be born quickly.
For those with qi deficiency and lack of strength, finding it difficult to transport the fetus, Dushen Decoction must be used, in varying amounts, to support their strength; these are all essential methods for inducing labor. If one recklessly uses formulas that move qi and guide blood before the due date, thinking this induces labor, it is akin to picking unopened flower buds or pulling up seedlings to help them grow (as in the fable of the Song person).
Tuohua Decoction (see *New Formulas Eight Arrays · Induction Array*): For those approaching parturition, it is advisable to take this medicine first; it is best for inducing labor and also effectively treats prolonged dystocia or retained dead fetus.
Angelicae Sinensis Radix (Danggui) (7-8 qian or 1 liang), Cinnamomi Cortex (Rougui) (1-2 qian or 3 qian), Ligusticum Chuanxiong Rhizoma (Chuanxiong), Achyranthis Bidentatae Radix (Niuxi) (each 2 qian), Plantaginis Semen (Cheqianzi) (1.5 qian), Carthami Flos (Honghua) (1 qian; for inducing labor, this ingredient may be omitted).
Add two zhong of water, decoct to obtain eight fen, take hot. Alternatively, drinking a few cups of wine after taking the medicine is also excellent. If the fetus is dead in the womb or stuck firmly and not descending, add Natrii Sulfas (Puxiao) 3-5 qian, and it will descend. If there is severe qi deficiency and exhaustion, add Ginseng Radix et Rhizoma (Renshen) as appropriate. If there is yin deficiency, definitely add Rehmanniae Radix Praeparata (Shudi) 3-5 qian.
Huatai Decoction (see entry on Huatai)
Dushen Decoction (see entry on Metrorrhagia and Metrostaxis with continuous bleeding)
When approaching parturition and abdominal pain is severe, among all medicines for inducing labor, none is superior to Tuohua Decoction. Using a small amount of Cinnamomi Cortex (Rougui), 5-7 fen, is the most stable and effective; if there is qi deficiency and lack of strength, add Ginseng Radix et Rhizoma (Renshen) 2-3 qian, which can be added arbitrarily for deficient conditions.
If, during induction, amniotic fluid and blood flow excessively, causing the birth canal to become dry and difficult for the baby to emerge, slippery substances should be used to lubricate, such as Porcine Adipose Oil (Zhuzhiyou), Honey Butter Oil (Misu You), Allii Tuberosi Bulbus (Congbai), Abutilonis Semen (Kuizi), Bovis Lac (Niu Ru), Talcum (Huashi), or Ulmi Cortex Albus (Yubaipi). This is also a method for emergency relief.
