产后血块作痛，多由产母难产过劳而成。或调护失宜，或寒邪凝滞，以致血停作痛。古法每用苏木、三棱、
莪术以迅攻之。时医多用归尾、红花以急行之，或延胡、牛膝以大破之。他如用山楂、砂糖以消块，姜椒、艾酒
以定痛，亦非良剂。至于治气胀用乌药、香附以顺之，枳壳、浓朴以顺之，又有用青皮、苏子以下气定喘，芩
连、栀柏以退热除烦。彼夫血枯便闭以承气汤下而愈。厥汗多，小便涩以五苓散通之而愈秘。此皆重虚，产母
非徒无益，反致变证百出。盖产后血块固宜消，新血亦宜生。必须行中带补，化中又生，可称善治。若生化汤能
使血块消而痛止，神清而气复，产后之至宝也。凡产儿下地，未进饮食之先，即服一剂后，

生化汤
当归（八钱） 川芎（三钱） 炙甘草（五分） 炮姜（五分，夏用四分） 桃仁（十粒，去皮尖捣）
水煎，入陈酒六七匙冲服。渣另用器储，候三剂头煎服完，将三渣作一剂水煎服。
产后百病皆血虚火盛，瘀血妄行而已，间有内伤饮食，外感风寒，然必先逐瘀补虚为主。若不兼逐瘀，
但服参 停滞之剂，必有瘀血攻心，即死者，食内太早亦然。故产母但觉小水短少即是病生，便须服药调理脾
胃肝肾。如不愈者，必气滞且逆。盖妇人凡事多忧思恚怒，忧思太过则气结而血亦结，恚怒太过则气逆而血
亦逆，甚则乳鞭胁痛。要之女病，皆因气血郁结，所以古方多用行气药。
产后血块引起的疼痛，大多是因为产妇难产或过度劳累所致。或者是调养护理不当，或是寒邪凝滞，导致血液停滞而引发疼痛。古法通常使用苏木、三棱、莪术来迅速攻破瘀血。当时的医生多使用当归尾、红花来急切地推动血行，或者使用延胡索、牛膝来大力破血。其他如使用山楂、砂糖来消除血块，生姜、花椒、艾叶酒来止痛，也都不是良方。至于治疗气胀使用乌药、香附来顺气，枳壳、厚朴来顺气，又有使用青皮、苏子来降气定喘，黄芩、黄连、栀子、黄柏来退热除烦的。那些因为血枯便秘用承气汤攻下而痊愈的案例。还有因汗多、小便涩滞用五苓散通利而看似痊愈实则更秘结的案例。这些都是加重虚损，对产妇不仅没有益处，反而会导致各种变证出现。大概产后血块固然应该消除，但新血也应该生成。必须在活血的同时兼顾补益，在化瘀的同时促进新生，这才能称为善于治疗。如果生化汤能使血块消散、疼痛停止，神志清醒、元气恢复，那就是产后的至宝。凡是胎儿娩出落地后，在未进食之前，立即服用一剂，之后再连续服用两剂，可以保全产后一切危重证候。
生化汤
当归（八钱） 川芎（三钱） 炙甘草（五分） 炮姜（五分，夏季用四分） 桃仁（十粒，去皮尖捣碎）
用水煎煮，加入陈年酒六七匙冲服。药渣另用容器储存，等到三剂药的头煎服完后，将三次的药渣合并作为一剂再次水煎服用。
产后百病都是由于血虚火盛，以及瘀血妄行罢了，间或有内伤饮食、外感风寒的情况，然而必须先以逐瘀补虚为主。如果不兼用逐瘀药，只服用人参等可能导致停滞的补剂，必然会有瘀血攻心的危险，甚至导致死亡，过早进食也是如此。所以产妇只要觉得小便短少，就知道是疾病发生，就必须服药调理脾胃肝肾。如果不见好转，必然是气滞且逆乱。大概妇人凡事多忧思愤怒，忧思太过则气机郁结而血液也郁结，愤怒太过则气机上逆而血液也上逆，严重时会出现乳房胀痛、胁肋疼痛。总之，女性疾病，都是因为气血郁结，所以古方多使用行气药物。
Pain caused by blood stasis (blood clots) after childbirth is mostly due to difficult labor or excessive fatigue of the mother. It may also result from improper care or stagnation of cold pathogenic factors, leading to blood stasis and pain. Ancient methods often used Suxmu (Lignum Pterocaryae Indicae), Sanleng (Rhizoma Sparganii), and Ezhu (Rhizoma Curcumae) to rapidly attack and resolve the stasis. Contemporary physicians frequently used Guiwei (Caudex Radix Angelicae Sinensis), Honghua (Flos Carthami Tinctorii) to urgently promote blood circulation, or Yanyuan (Fructus Corydalis) and Niuxi (Radix Achyranthis Bidentatae) to strongly break up blood stasis. Others such as using Shanzha (Fructus Crataegi), Sha Tang (Saccharum) to dissolve clumps, Jiang (Rhizoma Zingiberis Preparatum), Jiao (Fructus Zanthoxyli), Ai Ye (Folium Artemisiae Argyi), and Jiu (Vinum) to alleviate pain are also not considered good prescriptions. As for treating Qi distension with Wuyao (Radix Linderae), Xiangfu (Rhizoma Cyperi Rotundi) to regulate Qi, Zhike (Fructus Aurantii) and Houpo (Cortex Magnoliae Officinalis) to smooth Qi, or using Qingpi (Pericarpium Citri Reticulatae Viride), Suzi (Semen Perillae) to descend Qi and calm asthma, Huangqin (Radix Scutellariae), Huanglian (Rhizoma Coptidis), Zhizi (Fructus Gardeniae), Huangbai (Cortex Phellodendri) to clear heat and relieve irritability. Cases where constipation due to blood dryness was cured by purging with Chengqi Tang (Miracle Soup for Reversing the Deficiency). Also, cases where sweating and scanty urination were treated with Wuling San (Five-Ingredient Powder with Poria) to promote diuresis, resulting in apparent recovery but actually worsening constipation. These all exacerbate deficiency; they are not only ineffective for postpartum mothers but also lead to various complications. Generally, while postpartum blood stasis should be resolved, new blood must also be generated. One must combine blood-moving with tonifying, and resolving stasis with generating new blood; this can be called skillful treatment. If Shenghua Tang (Decoction for Generating New Blood) can eliminate blood stasis, stop pain, clarify the mind, and restore Qi, it is the supreme treasure for postpartum conditions. Whenever the baby is born, before any food intake, one dose should be taken immediately, followed by two consecutive doses, which can prevent all critical postpartum syndromes.
Shenghua Tang (Decoction for Generating New Blood)
Danggui (Radix Angelicae Sinensis) (8 qian) Chuanxiong (Rhizoma Chuanxiong) (3 qian) Zhi Gancao (Radix Glycyrrhizae Preparata) (5 fen) Paojiang (Rhizoma Zingiberis Preparatum) (5 fen, 4 fen in summer) Taoren (Semen Persicae) (10 grains, skin and tip removed, crushed)
Decoct in water, add 6-7 spoons of aged wine and take. Store the dregs separately in a container; after finishing the first decoction of three doses, combine the dregs from all three doses into one batch, decoct in water, and take.
All diseases after childbirth stem from blood deficiency and flourishing fire, along with reckless movement of blood stasis. Occasionally, there are internal injuries from diet or external contraction of wind-cold, yet the primary treatment must always be expelling stasis and tonifying deficiency. If one does not combine expelling stasis, but merely takes tonics like Renshen (Radix Ginseng) that may cause stagnation, blood stasis attacking the heart will inevitably occur, potentially leading to death; eating too early causes the same issue. Therefore, whenever a postpartum mother feels her urine is short in volume, she knows disease has arisen and must take medicine to regulate the Spleen, Stomach, Liver, and Kidney. If there is no improvement, it must be due to Qi stagnation and rebellion. Generally, women are prone to worry, thought, anger, and resentment. Excessive worry and thought cause Qi binding and subsequent blood binding; excessive anger causes Qi rebellion and subsequent blood rebellion, severely manifesting as breast swelling and costal pain. In summary, female diseases are all due to Qi and Blood stagnation, so ancient formulas often use Qi-regulating herbs.
