以上药物，用水一盏、陈酒半盏，煎煮至剩下一盏药液。趁稍热时服用。
“生化”之名，是根据药物的功效和作用而确立的。产后体内的陈旧血液应当消散，新的血液应当生成。如果只注重消散旧血，新血就无法生成；如果只注重生新血，旧血反而会停滞。考察这些药物的性质：川芎、当归、桃仁这三味药善于治疗陈旧性瘀血，专门促进新血生成；辅以黑姜和甘草，引导前三味药进入肝脾二经，在生血的同时调理气机，没有比这更好的了。这就是所谓的“在行血中蕴含补益，在化瘀中蕴含新生”，确实是产后的圣药。凡是怀孕到八、九个月时，应预备两到三剂药。等到胞衣破裂时，迅速煎服一剂。待胎儿娩出后，立即服用。无论是正常分娩还是小产，即使是身体强壮、平安无事的产妇，也应当服用两到三剂，这样恶露自然消散，新血自然生成。但必须在初次生产的一两个时辰内，且在未进食之前，连续煎服。因为恶露位于下焦，所以服药次数要多且频繁，以便使恶露容易化解、新血容易生成，从而避免发生血晕这种严重的后果。如果产前体质素来虚弱，以及产后因劳累倦怠，应当多服用两剂，以防止昏厥和疲倦。如果像平常那样每天只服一次，怎么能挽救那些气血将绝的危重情况呢？至于极度虚弱的患者出现危重症状，或因热病导致堕胎，或者因过度劳累导致身热头痛，即使服用了四五剂药后感觉稍微安稳，但如果腹部仍有块状疼痛未除，仍应当继续服用此方。
有的情况是产妇刚把孩子生出，无力排出胞衣；有的情况是经过时间太久或受冷风侵袭，导致血脉凝滞涩阻，从而胞衣不下；有的情况是产前体质素弱，到了血枯程度导致胞衣停滞。凡此种种，都应当紧急进服一两剂生化汤，同时服用益母膏，接着服用鹿角灰，这样血液旺盛、腹部调和，胞衣自然就会排出。世人常用济坤丹，又名回生丹，专门攻逐血块以脱落胞胎，虽然见效迅速，但难免损伤元气，务必谨慎使用。（制作益母膏的方法：在端午节后、小暑前，取新鲜的益母草，用铜锅熬制成膏，储存在瓷瓶中，不要让它漏气。临用时用生化汤调服，效果神奇。）
凡是胎儿已下而胞衣不下的情况，产妇不可躺倒睡觉。必须先剪断脐带，用草鞋坠住脐带（以防脐带回缩或出血过多）。如果是寒冷的月份，扶产妇到床上，让人搀扶着坐好，盖上被子，将火笼放在被子里，再用棉衣烘热替换，以温暖腹部。胞衣排出后，为了防止虚损，必须连续服用两到三剂生化汤，不要因为嫌药太频繁而厌烦，自然会有显著的效果。
Chuanxiong Rhizoma (Qianchuanxiong, 1.2 qian) Danggui Radix (Danggui, 5 qian) Zingiberis Rhizoma Ustam (Zhiheijiang, prepared black ginger, 0.5 qian) Glycyrrhizae Radix et Rhizoma Praeparata cum Melle (Zhigancao, honey-fried licorice, 0.3 qian) Persicae Semen (Taoren, peach kernel, peeled and pitted, ground, 11 grains)
Take the above herbs, add one cup of water and half a cup of aged wine, decoct until one cup of liquid remains. Take while slightly warm.
The name "Shenghua" is established based on the efficacy and function of the herbs. After childbirth, the residual blood should dissipate, and new blood should be generated. If one focuses solely on dissipating old blood, new blood will not be generated; if one focuses solely on generating new blood, residual blood will stagnate. Examining the properties of these herbs: Chuanxiong Rhizoma, Danggui Radix, and Persicae Semen are good at treating residual blood and specifically promote the generation of new blood. Assisted by Zingiberis Rhizoma Ustam and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, they guide the first three herbs into the Liver and Spleen meridians to generate blood and regulate Qi. Nothing is better than this. This is what is meant by "tonification within blood-moving, and generation within blood-resolving." It is truly the sacred medicine for postpartum conditions.
When pregnancy reaches the eighth or ninth month, prepare two or three doses in advance. When the amniotic sac ruptures, quickly decoct and take one dose. Immediately after the fetus is delivered, take it. Whether it is a normal delivery or a miscarriage, even for strong and healthy parturients, taking two or three doses is advisable so that lochia naturally dissipates and new blood naturally generates. However, it must be decocted and taken continuously within one or two hours of the first birth, before any food intake. Since lochia resides in the Lower Jiao (Lower Burner), frequent and multiple doses are necessary to facilitate the resolution of lochia and the generation of new blood, thereby avoiding severe complications such as Blood Fainting (Xueyun). For those with inherently weak constitutions before pregnancy, or suffering from fatigue and exhaustion after childbirth, two additional doses should be taken to prevent fainting and lethargy. Taking only one dose daily as usual cannot rescue critical depletion of Qi and Blood. Even for extremely deficient patients presenting with critical symptoms, or those who suffered abortion due to heat diseases, or those experiencing fever and headache due to severe overwork, if abdominal masses and pain persist despite feeling slightly relieved after four or five doses, this formula should still be continued.
Some cases arise because the mother lacks strength to expel the placenta immediately after delivering the infant. Some cases occur because too much time has passed or exposure to cold air causes blood vessels to become congealed and obstructed, leading to retained placenta. Some cases result from inherent weakness before pregnancy leading to blood depletion and stagnant placenta. In all such cases, urgently administer one or two doses of Shenghua Tang (Birth-Transforming Decoction), concurrently服用 Yimu Gao (Motherwort Paste), followed by Cervus Cornu Carbonisatum (Deer Horn Ash). This will strengthen the blood and harmonize the abdomen, causing the placenta to pass naturally. The world often uses Jikun Dan (Ji Kun Pill), also known as Huisheng Dan (Life-Returning Pill), which specifically attacks blood stasis to expel the placenta. Although it shows rapid effects, it inevitably damages the Yuan Qi (Original Qi); caution is advised. (Method for preparing Yimu Gao: After the Dragon Boat Festival and before Minor Heat, take fresh Motherwort Herba, decoct into paste using a copper pot, store in a porcelain bottle without letting air escape. When needed, mix with Shenghua Tang for miraculous effects.)
In cases where the infant is delivered but the placenta is retained, the parturient must not lie down. First, cut the umbilical cord and weigh it down with a straw shoe (to prevent retraction or excessive bleeding). In cold months, help the parturient to bed, support her to sit upright, cover her with a quilt, place a fire basket inside the quilt, and replace with heated cotton garments to warm the abdomen. After the placenta is expelled, to prevent deficiency, continue taking two or three doses of Shenghua Tang. Do not dislike the frequency of medication; significant effects will naturally follow.
