一产后气血暴虚，理宜大补。但恶露未尽，用补须兼行滞，能化又能生，攻块无损元气，行中
又兼补，始得万全。以四物汤理产，误人多矣。地黄性寒滞血，白芍酸寒无补故也。
一产后有块痛，名儿枕。世多专先耗散，后议补，又立消补混方。殊不知旧血须消化，新血当
生养。若专攻旧，生亦不宁，世以济坤丹（又名回生丹）治产，用以攻血块，下胞落胎。虽见速效，
其元气未免亏损，平安产妇莫视良剂，不得已用一丸可矣，不必多服。
一生化汤因药性功用而名也。夫产后血块当消，新血宜生，若专消则新血不宁，如专生则旧血
交滞。考诸药性，惟芎、归、桃仁善破旧血，骤生新血，佐以炮姜，甘草，引入肝肺，生血利气，行
中有补，化中有生，实产后妙方也。
生化汤 当归（八钱） 川芎（三钱） 桃仁（去皮尖十五粒） 黑姜 炙甘草（各五分
一本有陈皮）
煎好，入酒七匙。带热服，要在一二时内未进饮食前连进三服，服多而频则瘀速化，而骤生
新血，自免晕症。若胎前禀弱，及产后劳倦，又当再服两帖，以防危倦。且产妇服一帖，精神渐
增，自不厌服药之多。若照常间服一帖，只能扶危；若虚人见危症又热症，坠胎或劳甚，身潮头
痛，服至四五帖必安矣。如血痛又当再服。
凡将产时，预制二三帖，至胞衣一破，速煎一帖，候见下地即服。不问正产、半产，虽少壮
产妇平安无恙，宜服两帖，以消块生养新血。
新产及三日内服生化汤，两三日痛块未除再服。七日内血块未除，不可加参、 、术，致
痛不止。
产后气血突然虚弱，按理应当大补。但恶露尚未排尽，使用补法时必须兼用行气活血之法，既能化瘀又能生新，攻逐瘀血而不损伤元气，在行散中兼有补益，才算万全之策。用四物汤来调理产后病，误人很多。因为地黄性寒而滞血，白芍酸寒且无补益作用。
产后有块状疼痛，称为“儿枕”。世人多主张先耗散瘀血，再议补益，或者创立消补混杂的方剂。殊不知旧有的瘀血必须消化，新的血液应当生养。如果专事攻逐旧血，新血也无法安宁。世人用济坤丹（又名回生丹）治疗产后病，用来攻逐血块，促使胞衣脱落、胎儿娩出。虽然见效迅速，但元气难免亏损。平安生产的产妇不要将其视为良剂，实在不得已时服用一丸即可，不必多服。
生化汤因药物性质和功效而得名。产后血块应当消除，新血应当生成，如果专事消除则新血不安宁，如果专事生新则旧血交结阻滞。考察诸药药性，只有川芎、当归、桃仁善于破除旧血，迅速生成新血，佐以炮姜、甘草，引导药力入肝肺二经，生血利气，行散中兼有补益，化淤中兼有生新，确实是产后的妙方。
生化汤：当归（八钱）、川芎（三钱）、桃仁（去皮尖十五粒）、黑姜、炙甘草（各五分，原方中有陈皮）。煎好后，加入七匙酒。趁热服用，要在服药后一二小时内未进食前连续服用三次。服药次数多且频繁，则瘀血迅速化解，新血骤生，自然避免晕厥症状。如果胎前禀赋虚弱，以及产后劳倦，又应当再服两剂，以防危重疲倦。而且产妇服用一剂后，精神逐渐增加，自然不会厌恶服药之多。如果照常间隔服用一剂，只能扶持危局；如果是虚人出现危症又有热症，或坠胎、劳损严重，身体潮热头痛，服用至四五剂必定安稳。如伴有血痛，又应当再服。
凡是临产时，预先制备二三剂，等到胞衣破裂，迅速煎煮一剂，候见胎儿落地即服。不论正产、半产，即使是少壮产妇平安无恙，也宜服用两剂，以消除血块并生养新血。
After childbirth, Qi and Blood are suddenly deficient; theoretically, major tonification is appropriate. However, since lochia (postpartum discharge) has not yet cleared, when using tonification, one must simultaneously employ methods to move stagnation. This approach can transform stasis while generating new blood; removing masses does not damage Yuan Qi, and moving within the context of tonification achieves perfection. Using Siwu Tang (Four Substances Decoction) to manage postpartum conditions has misled many. Shudi (Rehmanniae Radix Preparata) is cold in nature and causes blood stasis; Baishao (Paeoniae Radix Alba) is sour and cold, lacking tonifying properties.
Postpartum mass pain is named "Erzhen" (Fetal Pillow). The world generally advocates first dispersing/consuming, then discussing tonification, or establishing mixed formulas for both eliminating and tonifying. Little do they know that old blood must be transformed/digested, and new blood should be generated/nourished. If one specializes in attacking old blood, generation will also be unsettled. The world uses Jikun Dan (also known as Huisheng Dan) to treat postpartum conditions, using it to attack blood masses and expel the placenta/fetus. Although it shows rapid effect, Yuan Qi is inevitably damaged. For safe deliveries, do not regard it as a good remedy; if absolutely necessary, take one pill, but do not take more.
Shenghua Tang is named after the properties and functions of its herbs. Postpartum blood masses should be eliminated, and new blood should be generated. If specializing in elimination, new blood will not be peaceful; if specializing in generation, old blood will become stagnant. Examining the properties of various herbs, only Xiong (Chuanxiong Rhizome), Gui (Angelicae Sinensis Radix), and Tao Ren (Persicam Semen) are good at breaking old blood and rapidly generating new blood. Assisted by Pao Jiang (Zingiberis Rhizoma Preparatum) and Gancao (Glycyrrhizae Radix et Rhizoma), guiding into the Liver and Lung meridians, generating blood and benefiting Qi, moving with tonification, transforming with generation, it is truly an excellent formula for postpartum conditions.
Shenghua Tang: Danggui (8 qian), Chuanxiong (3 qian), Taoren (15 grains, peeled and core removed), Heijiang (Black Ginger), Zhi Gancao (each 5 fen, original text mentions Chenpi). After decocting well, add 7 spoons of wine. Take hot. It is required to take three doses continuously within one to two hours before any food intake. Taking more frequently causes stasis to dissolve quickly and new blood to generate abruptly, thereby avoiding dizziness/syncope. If constitution was weak during pregnancy, or due to postpartum fatigue, two additional prescriptions should be taken to prevent critical exhaustion. Moreover, after taking one prescription, the patient's spirit gradually increases, naturally not disliking the frequent medication. If taken at intervals as usual, one prescription can only support critical conditions; if a deficient person presents with critical symptoms plus heat signs, or abortion/trauma, body tidal fever, headache, taking four to five prescriptions will surely bring peace. If accompanied by blood pain, further doses should be taken.
When approaching delivery, prepare two or three prescriptions in advance. Once the amniotic sac ruptures, quickly decoct one prescription and administer immediately upon the baby's descent. Regardless of normal delivery or miscarriage, even for young and strong women delivering safely, it is advisable to take two prescriptions to eliminate masses and nourish new blood.
For new births and within three days, take Shenghua Tang. If pain and masses persist after two or three days, take again. Within seven days, if blood masses remain, do not add Renshen (Ginseng Radix) or Baizhu (Atractylodis Macrocephalae Rhizoma), lest pain ceaselessly continue.
