产后二便不通者，因肠胃本挟热，产后水血俱下，津液耗竭，肠胃枯涩，热气燥结，故令
不通也。有产后患此，饮人乳、牛乳而通，故莫若补肾，盖肾主五液，肾主二阴也。
产后遗尿者，肾气不固也，五味子丸主之。若脾肾虚弱，以补中汤送还少丹。若脾
肾虚寒，用八味丸、四神丸佐之。
产后小便出血者，因气血虚而热乘之，血得热，而流渗胞内，故血随小便而出也。
有产妇尿血面黄，胁胀少食者，此肝木乘脾土也，用加味逍遥散、补中汤兼服而愈。
产后大便出血者，或饮食起居失宜，或六淫七情过极，致元气亏损，阴络受伤也。若因高粱积
热，醇酒湿毒，宜清之，怒动肝火，郁结伤脾，思虑伤心，宜和肝而调心脾。大肠风热血热，宜凉血
去风。肠胃虚弱，元气下陷，宜大补而兼升提。况产后气血大虚之后，复犯络伤失血之患，可不急固
脾元中气，以为摄血统血之用耶！
新产半月左右，忽发痈肿于四肢胸腹者，是败血不尽，流滞经络，或气血虚弱，荣气不从，逆于

扶胃气，气壮血和，其毒自解。若以毒治而用清凉解毒，势必不脓不溃，变成坏症矣。
产后二便不通，是因为肠胃原本挟有热邪，产后津液与血液同时下行，导致津液耗竭，肠胃干枯涩滞，热气燥结，所以造成大小便不通。有的产妇患此病，饮用人的乳汁或牛的乳汁后得以通畅，因此治疗不如补肾，因为肾主管五液，且肾开窍于前后二阴。
产后遗尿，是肾气不固摄所致，可用五味子丸主治。如果是脾肾虚弱，用补中益气汤送服还少丹。如果是脾肾虚寒，用八味丸、四神丸辅助治疗。
产后小便出血，是因为气血虚弱而热邪乘虚而入，血受热则流动渗溢进入胞宫，所以血液随小便排出。有的产妇出现尿血且面色发黄、胁肋胀满、食欲不振，这是肝木克制脾土的表现，服用加味逍遥散和补中益气汤兼治即可痊愈。产后大便出血，或者是饮食起居不当，或者是六淫（风、寒、暑、湿、燥、火）七情（喜、怒、忧、思、悲、恐、惊）过度，导致元气亏损，阴络受伤。如果是因为高梁厚味积热、醇酒湿毒引起，应当清热；如果是因愤怒触动肝火、郁结损伤脾脏、思虑损伤心脏，应当调和肝脏并调理心脾。如果是大肠风热血热，应当凉血祛风。如果是肠胃虚弱、元气下陷，应当大补元气并兼用升提之法。况且产后气血极度虚弱之后，又犯了络脉受伤失血的祸患，怎能不急于固护脾胃的中气，以起到统摄血液的作用呢！
新产半个月左右，突然在四肢胸腹发生痈肿，这是因为败血未尽，流注停滞在经络，或者是气血虚弱，营气运行不畅，逆乱于肌肉纹理之间。如果是败血瘀滞，则表现为肿胀发红疼痛，脉象弦洪有力，应当在补血行血之中，辅以引导瘀血、疏通气机为主。如果是气血虚弱，营气涩滞、卫气逆乱，则表现为疮形平塌散漫，脉象虚微无力，应当以大补气血为主，如使用十全大补汤、八珍汤之类的方剂，以固护根本元阳、扶助胃气，气壮血和，毒邪自然解除。如果用治毒的方法而使用清凉解毒药，势必导致不化脓也不溃破，变成坏症。
Postpartum obstruction of both urination and defecation occurs because the intestines and stomach originally harbored heat pathogens. After childbirth, fluids and blood descend together, leading to exhaustion of body fluids, dryness and astringency of the intestines and stomach, and accumulation of heat causing dryness and impaction, thus resulting in obstruction. In some cases where postpartum patients suffer from this condition, drinking human or cow's milk relieves the symptoms; therefore, treatment is best achieved by tonifying the Kidney, as the Kidney governs the five fluids and opens into the two lower orifices (urethra and anus).
Postpartum urinary incontinence is caused by insecurity of Kidney Qi. It should be treated with Wuweizi Wan (Schisandra Berry Pill). If Spleen and Kidney are weak, Buzhong Yiqi Tang (Decoction for Boosting the Middle and Augmenting Qi) should be administered to deliver Huanshao Dan (Return to Youth Pill). If Spleen and Kidney are deficient and cold, Bawei Wan (Eight-Ingredient Pill) and Sishen Wan (Four Spirits Pill) should be used as adjuvants.
Postpartum hematuria (blood in urine) occurs due to deficiency of Qi and Blood allowing heat pathogens to invade. When blood is affected by heat, it flows and seeps into the uterus, causing blood to exit with urine. Some parturient women present with hematuria, sallow complexion, hypochondriac distension, and poor appetite; this indicates Liver Wood overacting on Spleen Earth. They can be cured by concurrently administering Jiawei Xiaoyao San (Modified Free and Easy Wanderer Powder) and Buzhong Yiqi Tang. Postpartum hematochezia (blood in stool) may result from improper diet and lifestyle, or from excessive exposure to the Six Excesses (Wind, Cold, Summerheat, Dampness, Dryness, Fire) and Seven Emotions (Joy, Anger, Worry, Pensiveness, Sadness, Fear, Fright), leading to depletion of Yuan Qi (Original Qi) and injury to Yin collaterals. If caused by accumulation of heat from rich food and alcohol damp-toxins, clearing heat is indicated. If caused by anger stirring Liver Fire, stagnation injuring the Spleen, or overthinking injuring the Heart, harmonizing the Liver and regulating the Heart and Spleen is indicated. For Wind-Fire and Blood-Heat in the Large Intestine, cooling Blood and dispelling Wind is indicated. For weakness of the intestines and stomach with sinking of Yuan Qi, major tonification combined with lifting is indicated. Moreover, after the severe deficiency of Qi and Blood following childbirth, if one suffers again from collateral injury and blood loss, how can one not urgently consolidate the Middle Qi of the Spleen and Stomach to serve the function of controlling and retaining blood?
Around half a month after new childbirth, sudden carbuncles and swellings appearing on the limbs, chest, and abdomen indicate that lochia (decayed blood) is incomplete, flowing and stagnating in the collaterals, or that Qi and Blood are weak, causing Ying Qi (Nutritive Qi) to fail to follow its course and reverse into the muscle tissue. If caused by lochia stasis, symptoms include swelling, redness, pain, and a wiry, surging, and forceful pulse; treatment should focus on nourishing and moving Blood, assisted by guiding out stasis and unblocking Qi. If caused by Qi and Blood deficiency with stagnant Ying Qi and reversed Wei Qi (Defensive Qi), symptoms include flat, diffuse swellings and a faint, minute, and forceless pulse; treatment should primarily involve major tonification of Qi and Blood, using formulas such as Shiquan Dabu Tang (Ten Complete Great Tonifying Decoction) or Bazhen Tang (Eight Treasure Decoction) to solidify the root and support Stomach Qi. When Qi is strong and Blood is harmonious, the toxin resolves spontaneously. If toxic diseases are treated with cooling and detoxifying herbs, it will inevitably lead to failure to suppurate or ulcerate, resulting in a disastrous complication.
