《脉经》云∶产后之脉，寸口洪疾不调者死，况微附骨不绝者生。又曰∶沉小缓滑者吉，实大坚
弦疾者凶，牢革结代及涩滞不调者不治。丹溪曰∶胎前脉当洪数，既产而脉仍洪数者死。又曰∶胎前
脉细小，产后脉洪大者多死。予见产后多有洪数而生者，要知血虚之脉浮洪而数者居多，产后血虚，
故现此脉。若不明以告之，俗医多误认为外感，虚虚之祸，在此顷刻。然此洪数之中，自有和滑之象
，非如牢疾而少胃气之谓，故多死也。《产经》曰∶胎前之病，其脉贵实；产后之病，其脉贵虚。胎前
则顺气安胎，产后则补虚消瘀，此其要也。
生化汤论曰∶产后诸症，皆缘气血骤下，元气大亏，用药不同常法。是以有极不能姑待者，则当
峻补之中，加入温行之药，峻补则力大而可宣通。温行则流畅而不凝滞。至于逐瘀之剂，即实症亦不
可用峻厉之药，况产后大虚，恐血无主宰，一任药力便为崩而不止，虚则易脱，势如覆水难收矣。夫
人遇大病之后，血气两虚，犹当调补，况产后脾胃血气之虚衰，更有甚焉者乎？今之治产后者，亦云∶
元气因产而亏，营运失度，不免瘀血停留，致成诸疾，必以去瘀为先，瘀消方可行补，甚有用回生丹，
攻血块，下胞衣，殒人性命者。此盖止知专攻旧瘀，而不知新血转伤之害，岂知块固当消，而新血犹当生也。盖专消则
新血不生，专生则旧血反滞。予考新产诸方，莫若生化汤为产后第一妙方。其方芎、归、桃仁温中行血，善去旧血，骤
生新血；佐以炙黑干姜、炙草，引三味入于肺、肝，行中有补，化中有生，故名生化，盖因功而立名也。又有加入益母
草一钱五分，功效亦同。此实治产之良方，保全产妇之圣药也。故冯氏因此方之妙，变化用于临产，加人参、桂、牛
膝、红花，又为催生之神剂矣。
生化汤方 凡孕妇临月，即预备生化汤数剂，俟临产之时，即为预先煎就。产下，随服二、
三道，以逐瘀生新，再无产后之患。无论正产、半产，虽少壮产妇，俱宜服之。故此汤为产后七
日内要药。倘产下之时，未及煎服，凡产后诸症，仍以此汤治之。
全当归（八钱酒洗） 川芎（四钱） 干姜（四分炙黑存性） 桃仁（十粒去皮尖，打碎）
炙草（五分）
水二盅，煎七分，加酒小半盅。如素日不能饮酒者，加六、七茶匙，稍热服之。其药渣留，
并后帖药渣，合而再煎，而帖共三煎，在产下一、二时辰内，未进饮食先相继煎服。能速化旧血
而骤生新血，不特可免目前晕厥、汗、崩、恶露停滞等患，且诸病不生，精神百倍矣。如胎前
素虚之人，产后又当再制两帖煎服，以防倦怠。若产下已服一、二帖，而块痛未除，仍当再进几
帖，块痛自消矣。
《脉经》说：产后脉象，如果寸口部位脉搏洪大急疾且不调和的，预后不良；而如果脉象微弱但按之至骨仍有根气的，则预后良好。又说：脉象沉、小、缓、滑的是吉兆；脉象实、大、坚、弦、疾的是凶兆；脉象牢、革、结、代以及涩滞不调的，属于难治之症。朱丹溪说：妊娠期间脉象应当洪大数急，分娩后脉象仍然洪大数急的，预后不良。又说：妊娠期间脉象细小，分娩后脉象反而洪大的，大多预后不良。我见到产后有许多脉象洪大数急而痊愈的，要知道血虚导致的脉象多为浮、洪、数，因为产后血虚，所以出现这种脉象。如果不明确告知这一点，世俗医生多误认为是外感病证，导致“虚虚”（使虚者更虚）的祸患，往往就在顷刻之间。然而在这种洪数脉中，自然带有和缓滑利的象，不像那种牢疾而缺乏胃气的脉象，所以那些脉象才会导致死亡。《产经》说：妊娠期间的疾病，脉象以充实为贵；产后的疾病，脉象以虚弱为贵。妊娠期应当顺气安胎，产后应当补虚消瘀，这是治疗的要点。
关于生化汤的论述说：产后的各种病症，都是因为气血突然下行，元气严重亏损所致，用药不能遵循常规方法。因此有极不能等待的情况，应当在峻补之中，加入温通运行的药物。峻补则药力宏大，可以宣通；温通则药性流畅而不凝滞。至于逐瘀的方剂，即使是实证也不可用猛烈攻伐的药物，何况产后身体极度虚弱，恐怕血液失去统摄，任由药力作用就会导致崩漏不止，虚损容易脱失，形势如同泼出去的水难以收回。妇女在大病之后，气血两虚，还应当调补，何况产后脾胃气血的虚衰，更有甚于此的呢？现在治疗产后病的医生也说：元气因生产而亏损，运行营运失去节度，不免有瘀血停留，导致各种疾病产生，必须以祛除瘀血为先，瘀血消除后方可进行补益，甚至有人使用回生丹，攻逐血块，排出胞衣，导致病人死亡的案例。这大概只知道专门攻逐旧有的瘀血，而不知道损伤新血的危害，哪里知道血块固然应当消除，但新血也应当生成呢。如果专门消除瘀血，新血就无法生成；如果专门生血，旧血反而会停滞。我考察新生的各种方剂，没有比得上生化汤作为产后第一妙方的。这个方子用川芎、当归、桃仁温中行血，善于去除旧血，迅速生成新血；佐以炙黑干姜、炙甘草，引导这三味药进入肺、肝二经，行血中有补益，化瘀中有新生，所以命名为生化，是因为功效而得名。又有加入益母草一钱五分的，功效也是一样的。这确实是治疗产后的良方，保全产妇生命的圣药。所以冯氏因为这个方子的奇妙之处，变化用于临产时，加入人参、桂枝、牛膝、红花，又成为了催生的神效药剂了。
生化汤方：凡是孕妇临近预产期，就预备几剂生化汤，等到临产之时，预先煎好。胎儿娩出后，随即服用二到三剂，以祛除瘀血、生成新血，就不会再有产后的病患。无论是正常分娩还是流产，即使是年轻体壮的产妇，都适宜服用。所以此汤是产后七日内的要药。倘若分娩时来不及煎服，凡产后出现的各种病症，仍以此汤治疗。
全当归（八钱，酒洗） 川芎（四钱） 干姜（四分，炙黑存性） 桃仁（十粒，去皮尖，捣碎） 炙甘草（五分）
用水两盅，煎至七分，加入小半盅酒。如果平时不能饮酒的人，加入六、七茶匙酒，稍热服用。药渣保留，并与后面帖数的药渣合并再煎，共煎三次，在分娩后一到两个时辰内，在未进食之前相继煎服。能迅速化解旧血而快速生成新血，不仅可避免目前的晕厥、出汗、崩漏、恶露停滞等病患，而且诸病不生，精神百倍。如果妊娠期间素体虚弱的人，产后又应当再制作两帖煎服，以防倦怠。如果分娩后已经服用了一、两帖，但腹痛包块未除，仍应当再进服几帖，腹痛包块自然会消除。
According to the *Mai Jing* (Pulse Classic), regarding postpartum pulses: if the pulse at the Cun Kou (inch position) is flooding, rapid, and irregular, it indicates a fatal prognosis; whereas if the pulse is faint but still palpable deep against the bone (indicating root Qi), it indicates survival. It further states that sinking, small, slow, and slippery pulses are auspicious, while excessive, large, firm, wiry, and rapid pulses are ominous. Pulses that are firm, leathery, knotted, intermittent, or choppy and irregular are considered intractable. Zhu Danxi stated that during pregnancy, the pulse should be flooding and rapid; if it remains flooding and rapid after delivery, the prognosis is poor. He also said that if the pulse was fine and small during pregnancy but becomes flooding and large after delivery, death is likely. I have observed many cases where patients recovered despite having flooding, rapid pulses postpartum. One must understand that floating, flooding, and rapid pulses are common due to Blood deficiency. Since postpartum Blood deficiency is prevalent, these pulses appear. If this is not clearly explained, lay physicians often misdiagnose it as an external contraction (Exogenous pathogen invasion). The disaster of "making the deficient more deficient" can occur in an instant. However, within this flooding and rapid quality, there is naturally a harmonious and slippery aspect. This is unlike the firm and rapid pulse lacking Stomach Qi, which leads to death. The *Chan Jing* (Obstetric Classic) states: for diseases during pregnancy, the pulse should be substantial; for diseases after delivery, the pulse should be deficient. During pregnancy, one should soothe Qi and calm the fetus; after delivery, one should tonify deficiency and resolve stasis. This is the key principle.
Regarding the discussion on Shenghua Tang: Various conditions after delivery arise because Qi and Blood suddenly descend, causing severe depletion of Yuan Qi (Primal Qi). Medication cannot follow ordinary methods. Therefore, in cases that cannot wait, one must add warming and moving herbs within strong tonification. Strong tonification provides great force to promote circulation; warming promotes smooth flow without stagnation. As for formulas that expel stasis, even in excess patterns, harsh purgative drugs should not be used. How much less so in the case of severe postpartum deficiency? There is fear that the Blood will lose its master (control), and任由 the drug's power causes hemorrhage that does not stop. Deficiency easily leads to collapse, a situation like spilt water that cannot be gathered. After a major illness, when both Qi and Blood are deficient, regulation and tonification are still necessary. How much more so for the deficiency and decline of Spleen-Stomach Qi and Blood after delivery? Physicians treating postpartum conditions today say: Yuan Qi is depleted by childbirth, leading to disordered circulation and retention of Blood stasis, causing various diseases. One must prioritize removing stasis; only after stasis is cleared can tonification proceed. Some even use Huisheng Dan (Revival Pill) to attack blood masses and expel the placenta, resulting in death. This is because they only know how to specifically attack old stasis, unaware of the harm caused to new Blood. They do not realize that while masses must be eliminated, new Blood must also be generated. Specifically eliminating stasis prevents new Blood from forming; specifically generating Blood causes old stasis to stagnate. In my examination of formulas for recent delivery, none surpasses Shenghua Tang as the premier excellent formula for postpartum care. This formula uses Xiong (Chuanxiong Rhizome), Gui (Danggui Radix), and Tao Ren (Persicae Semen) to warm and move Blood, effectively removing old stasis and rapidly generating new Blood. It is assisted by Zhi Hei Gan Jiang (Charred Dried Ginger) and Zhi Cao (Prepared Licorice Root) to guide the three ingredients into the Lung and Liver meridians. Moving within tonification, transforming within generation—hence named Shenghua (Generate and Transform), named for its efficacy. Adding Yi Mu Cao (Leonuri Herba) at 1.5 qian also yields similar efficacy. This is truly a good formula for treating childbirth, a sacred medicine for preserving the mother's life. Thus, Feng Shi, recognizing the miracle of this formula, modified it for use during labor by adding Ren Shen (Ginseng Radix), Gui Zhi (Cinnamomi Ramulus), Niu Xi (Achyranthis Bidentatae Radix), and Hong Hua (Carthami Flos), creating a divine agent for inducing labor.
Shenghua Tang Formula: Whenever a pregnant woman near term, prepare several doses of Shenghua Tang in advance. When labor begins, decoct it beforehand. After delivery, take two or three doses immediately to expel stasis and generate new Blood, preventing any postpartel complications. Whether for normal delivery or miscarriage, even for young and robust mothers, it is suitable. Thus, this decoction is a crucial medicine for the first seven days postpartum. If it was not decocted and taken at the time of delivery, for any postpartum conditions, treat with this decoction nonetheless.
Quan Dang Gui (8 qian, washed with wine), Chuan Xiong (4 qian), Gan Jiang (4 fen, charred black retaining nature), Tao Ren (10 grains, skin and tip removed, crushed), Zhi Cao (5 fen).
Decoct with 2 zhong of water until reduced to 7/10. Add a small half zhong of wine. For those who usually cannot drink alcohol, add 6-7 tea spoons of wine. Take slightly warm. Retain the dregs, combine them with the dregs of subsequent doses, and decoct again. Total three decoctions. Within one to two shichen (2-4 hours) after delivery, before taking food, decoct and take successively. This can quickly transform old Blood and rapidly generate new Blood. Not only does it prevent current conditions such as syncope, sweating, hemorrhage, and lochia stasis, but it also prevents other diseases and restores spirit and energy manifoldly. For those constitutionally deficient during pregnancy, prepare two additional doses after delivery to prevent fatigue. If one or two doses have been taken after delivery but abdominal pain and masses persist, continue taking several more doses; the pain and masses will naturally subside.
