张仲景曰∶问，新产妇人有三病，一者病痉，二者病郁冒，三者大便难，何谓也？师曰∶新产血虚，多汗
出，喜中风，故令病痉。亡血复汗，寒多，故令郁冒。亡津液，胃燥，故大便难。

张仲景说：问，新产妇人有三病，一者病痉（痉挛抽搐），二者病郁冒（头晕目眩、意识模糊），三者大便难，是什么意思呢？老师说：新产后血虚，多汗出，容易感受风邪，所以导致病痉。失血后又出汗，寒气重，所以导致郁冒。津液耗伤，胃中干燥，所以导致大便难。
《千金方》说：妇人产后十二病。带下无子，都是由于风冷寒气所致，或者产后未满百日，胞络恶血未尽，就利于悬圊（指在厕所或高处如厕），以及久坐寒湿侵入胞宫内部，结聚在小腹，坚硬疼痛形成积聚，小的像鸡蛋，大的像拳头，按压时跳动隐隐作痛，或者像虫咬，或者像针刺，气机有时上冲心胸，两胁支撑胀满，不能进食，饮食不消化。
《大全》说：产后十八证。一是因热病胎死腹中。二是难产。三是胞衣不下。四是血晕。五是口干心闷。六是乍寒乍热。七是虚痛。八是乍见鬼神。九是月内不语。十是腹痛泄泻。十一是遍身疼痛。十二是血崩。十三是血气不通、咳嗽。十四是寒热心痛、月候不来。十五是腹胀满，呕逆。十六是口鼻黑气及鼻衄。十七是喉中气喘急。（以上两种证候都不治。）十八是中风。
张飞畴说：产后诸证，如果不行血则邪气不去。即使是各种虚证，也必须让血运行，其气才能恢复。只是行血要有方法，不可过于峻猛。凡是产后危证，没有比三冲三急更严重的了。三冲者，败血冲肺、冲心、冲胃也。三急者，新产的呕吐、泄泻、多汗也。其用药则有三禁，禁佛手散，因为川芎能发汗；禁四物汤，因为地黄能致泻；禁小柴胡汤，因为黄芩能阻碍恶露排出。然而这些都是产后常法，如果没有风寒发热喘胀，下痢，危急证候，也要遵守此法，致使坐以待毙吗？古人未尝不用汗下法，不用寒凉药。而暴病势紧，不得不猛治的，下手稍软，畏缩逡巡，离死亡就近了。只有病气久衰者，不仅不可峻攻，也不可峻补，必须用缓剂轻剂，以等待胃气的恢复罢了。
Zhang Zhongjing said: "Inquiry: A woman who has just given birth suffers from three diseases: one is Jing (spasm and convulsion), the second is Yumao (dizziness, vertigo, and confusion of consciousness), and the third is difficulty in defecation. What does this mean?" The Master said: "After childbirth, blood deficiency occurs, accompanied by excessive sweating, making the body susceptible to wind pathogenic factors; thus, Jing (spasm and convulsion) arises. Loss of blood followed by sweating leads to an excess of cold; thus, Yumao (dizziness, vertigo, and confusion of consciousness) arises. Depletion of body fluids results in dryness of the Stomach; thus, difficulty in defecation arises."
Qianjin Fang states: "Twelve postpartum diseases in women. Leukorrhea and infertility are all caused by wind-cold pathogenic factors. If within one hundred days after childbirth, when lochia remains in the uterine collaterals and has not been fully expelled, the patient uses a high toilet (xuan qing), or sits for long periods allowing cold-dampness to enter the interior of the uterus, stagnation forms in the lower abdomen. This presents as firm, painful masses. Small masses are like chicken eggs, large ones like fists. Upon palpation, they throb faintly; the sensation may feel like insect bites or needle pricks. Qi occasionally rushes to the heart region, causing distension and fullness in both hypochondria, inability to eat, and indigestion."
Daquan states: "Eighteen postpartum syndromes. One: fetal death in the womb due to febrile disease. Two: difficult labor. Three: retention of the placenta. Four: blood syncope. Five: dry mouth and chest oppression. Six: alternating chills and fever. Seven: deficiency pain. Eight: hallucinations of seeing ghosts and spirits. Nine: muteness within the first month. Ten: abdominal pain with diarrhea. Eleven: generalized body pain. Twelve: metrorrhagia (profuse uterine bleeding). Thirteen: obstruction of blood and qi with cough. Fourteen: alternating chills and fever, heart pain, and amenorrhea. Fifteen: abdominal distension and fullness with vomiting and regurgitation. Sixteen: black aura around the mouth and nose, and epistaxis. Seventeen: wheezing and急促 breathing in the throat. (The last two syndromes are considered untreatable.) Eighteen: wind-stroke."
Zhang Feichou said: "For various postpartum syndromes, if blood circulation is not promoted, pathogenic factors will not be eliminated. Even in cases of various deficiency syndromes, blood must circulate for Qi to recover. However, promoting blood circulation must be done with proper method and should not be overly harsh. Among all postpartum critical conditions, none are more severe than 'Three Rushes' (San Chong) and 'Three Urgencies' (San Ji). The Three Rushes refer to敗血 (stagnant blood) rushing to the Lung, Heart, and Stomach. The Three Urgencies refer to vomiting, diarrhea, and excessive sweating immediately after childbirth. There are three prohibitions in medication: Banish Foshou San because Chuanxiong Radix (Chuanxiong) can induce sweating; banish Siwu Tang because Rehmanniae Radix Preparata (Shudi) can cause diarrhea; banish Xiaochaihu Tang because Scutellariae Radix (Huangqin) can obstruct the expulsion of lochia. However, these are merely standard methods for postpartum care. If there were no wind-cold, fever, wheezing, distension, dysentery, or other critical conditions, would one strictly adhere to these rules and sit waiting for death? Did ancients never use diaphoretic and purgative methods, nor cold-natured herbs? When acute diseases present with rapid progression, drastic treatment is necessary. If the physician hesitates, acts timidly, or delays, the patient's chance of survival diminishes. Only in cases where the pathogenic factor has been depleted over a long period should one avoid both drastic attack and drastic tonification; instead, mild and gentle formulas should be used to await the recovery of Stomach Qi."
