产后尿血，小腹痛者，乃败血流入膀胱。小腹不痛，但溺时涩痛者，乃内热也。并用小
蓟汤主之。《尊生》用加味肾气去桂附，加生地、发灰治之。至于大便便血，或因饮食起居
失宜，或因六淫七情过极，至元气亏损，阴络受伤也。四君子加生地、升麻、归身、白芍、
发灰治之。
小蓟汤∶小蓟根、生地、赤芍、木通、蒲黄、淡竹叶、甘草稍（生）各一钱，滑石二钱，
灯心四十九寸，水煎服。败血加归尾、红花各一钱，兼内热加黄芩、去心麦冬各一钱。
产后月水不通者，不必药也。上为乳汁，下为月水，若产后去血过多，常有月水不通。
若乳子者，半岁一岁之内，月经不行，此犹常候。若半岁左右便行，是必少壮血盛之人。若
产后一二年月经不通，无他疾苦，亦不必服通经之药。盖因劳伤荣卫，冲任脉虚，气血衰少
耳，但服健脾胃及滋补气血之药，自然通行。若强通之，是犹揠苗者也。

产后尿血，小腹痛的，是败血流入膀胱。小腹不痛，只是排尿时涩痛的，是内热所致。均用小蓟汤主治。《尊生》用加味肾气丸去掉桂枝、附子，加入生地、发灰来治疗。至于大便便血，或因饮食起居不当，或因六淫七情过度，导致元气亏损，阴络受伤。用四君子汤加生地、升麻、归身、白芍、发灰治疗。
小蓟汤：小蓟根、生地、赤芍、木通、蒲黄、淡竹叶、甘草稍（生）各一钱，滑石二钱，灯心四十九寸，水煎服。若有败血，加归尾、红花各一钱；兼有内热，加黄芩、去心麦冬各一钱。
产后月经不通的，不必用药。乳汁上行，经水下行为月水，若产后失血过多，常有月经不通的情况。如果是哺乳期的妇女，在半岁到一岁之内，月经不来，这还是正常的现象。如果产后半年左右月经就来了，那一定是年轻力壮、气血旺盛的人。如果产后一两年月经不通，没有其他疾病痛苦，也不必服用通经的药物。这是因为劳损伤及荣卫，冲任脉虚，气血衰少罢了，只要服用健脾胃及滋补气血的药物，自然就会通行。如果强行通经，这就如同拔苗助长一样。
新产半个月左右，忽然在四肢胸腹发生痈肿的，是败血未尽，流滞经络；或是气血虚弱，营气不从，逆于肌肉纹理之间。如果是败血瘀滞，则肿胀发红疼痛且脉象弦洪有力，应当在补血行血之中，以辅助导瘀疏气为主。如果是血气虚弱，营涩卫逆，则疮形平塌散漫且脉象虚微无力，应当以大补气血为主，如十全大补汤、八珍汤之类，以固本元、扶胃气，气壮血和，毒邪自然解除。如果用毒药治疗而使用清凉解毒的方法，势必导致不化脓不溃破，变成坏症了。
Postpartum hematuria with lower abdominal pain is due to retained blood flowing into the bladder. Lower abdominal pain-free but painful and difficult urination is due to internal heat. Both are primarily treated with Xiaojie Tang (Little Thistle Decoction). *Zunsheng* uses Jiawei Shenqi Wan (Modified Kidney Qi Pill) with Cinnamon Twig (*Guizhi*) and Aconite Root (*Fuzi*) removed, plus Rehmannia Root (*Shengdi*) and burnt hair (*Fahui*). As for hematochezia (blood in stool), it may be caused by improper diet and lifestyle, or by extreme excess of the six climatic factors (*Liuyin*) and seven emotions (*Qiqing*), leading to depletion of Yuan Qi (Original Qi) and injury to the Yin collaterals. It is treated with Sijunzi Tang (Four Gentlemen Decoction) plus Rehmannia Root (*Shengdi*), Cimicifuga Rhizome (*Shengma*), Angelica Sinensis Root (*Guishen*), White Peony Root (*Baishao*), and burnt hair (*Fahui*).
Xiaojie Tang: Little Thistle Root (*Xiaoji Gen*), Rehmannia Root (*Shengdi*), Red Peony Root (*Chishao*), Akebia Stem (*Mutong*), Polygonum orientale Seed (*Puhuang*), Lophatherum Herb (*Danzhuye*), Licorice Root tip (*Gancao Shao*, raw) each 1 qian, Talcum (*Huashi*) 2 qian, Juncus Effusus Stem (*Dengxin*) 49 cun, decocted in water and taken orally. For retained blood, add Angelica Sinensis Tail (*Guiwei*) and Safflower (*Honghua*) each 1 qian; for concurrent internal heat, add Scutellaria Root (*Huangqin*) and Ophiopogon Tuber (*Maidong*, heart removed) each 1 qian.
Postpartum amenorrhea does not necessarily require medication. Milk flows upward, menstruation flows downward. If excessive blood loss occurs postpartum, amenorrhea is common. For nursing mothers, the absence of menstruation within half a year to one year is still a normal condition. If menstruation returns around half a year postpartum, the woman must be young, vigorous, and abundant in blood and qi. If menstruation does not return one to two years postpartum without other discomforts, there is no need to take medicines to promote menstruation. This is because labor has injured Ying and Wei (Nutritive and Defensive Qi), the Chong and Ren vessels are deficient, and blood and qi are depleted. Simply taking medicines to strengthen the spleen and stomach and nourish blood and qi will naturally restore flow. Forcing menstruation is like pulling shoots to help them grow.
Around half a month after childbirth, sudden carbuncles and swellings on the limbs, chest, and abdomen are due to incomplete expulsion of retained blood stagnating in the collaterals, or due to deficiency of blood and qi causing Ying Qi to fail to follow its course and reverse into the muscle tissue. If due to retained blood stasis, there is swelling, redness, pain, and a wiry, flooding, and forceful pulse. Treatment should focus on nourishing and moving blood, assisted by guiding out stasis and dispersing qi. If due to blood and qi deficiency with stagnant Ying and reversed Wei, the lesion is flat, diffuse, and the pulse is deficient, minute, and weak. Treatment should primarily greatly tonify blood and qi, such as using Shiquan Dabu Tang (Ten Complete Great Tonifying Decoction) or Bazhen Tang (Eight Treasures Decoction), to consolidate the root, support stomach qi, strengthen qi, harmonize blood, and allow the toxin to resolve spontaneously. If treated with toxic substances or cooling detoxification methods, it will inevitably fail to suppurate and ulcerate, turning into a disastrous condition.
