产后淋症，此亦血去阴虚生内热也。盖肾为至阴，主行水道，去血过多，正阴亏损，故生内热，
小便成淋而涩痛。是以热客于脬，虚则频数，热则涩痛也。气血兼热，血入胞中，则血随小便而为
血淋。但小便淋闭却与不通当分别而治。不通者，属气虚，淋属内热涩痛，故密斋治淋，用知柏
导赤散、调益元散治之。冯氏云∶血虚热郁，当用六味丸、逍遥散，补阴养血，滋其化源，佐以
导血药可也。

产后淋症，这也是因为失血过多导致阴虚，进而产生内热所致。肾为至阴之脏，主管水液代谢通道，失血过多会导致真阴亏损，因此产生内热，使小便变成淋证并伴有涩痛。这是因为热邪客居膀胱（脬），虚则导致小便频数，热则导致排尿涩痛。如果气血兼有热邪，血液进入胞宫（子宫），血液就会随着小便排出而形成血淋。但是，小便淋闭不通的情况却需要与“不通”证分别进行治疗。所谓“不通”，属于气虚；而淋证属于内热引起的涩痛，所以密斋治疗淋证，使用知柏导赤散、调益元散来治疗。冯氏说：如果是血虚且热邪郁结，应当使用六味丸、逍遥散，以补阴养血，滋养化源，辅以引导血液的药物即可。

产后尿血、小腹痛的，是败血流入膀胱所致；小腹不痛，只是排尿时涩痛的，是内热所致。这两种情况都用小蓟汤主治，《尊生》篇中使用加味肾气汤，去掉桂枝、附子，加入生地、发灰来治疗。至于大便便血，可能是因为饮食起居不当，或者因为六淫（风、寒、暑、湿、燥、火）和七情（喜、怒、忧、思、悲、恐、惊）过度，导致元气亏损，阴络受伤。这种情况用四君子汤加上生地、升麻、归身、白芍、发灰来治疗。

产后七日内，因外感风寒引起咳嗽，鼻塞声重，恶寒的，只需服用生化汤即可自愈，因为方中含有川芎、生姜可以驱散邪气，或者在生化汤中加入杏仁、桔梗。如果有痰，加入天花粉。还有加味生化汤，也都用于治疗这些症状，总之不使用麻黄来发汗，即使咳嗽伴有胁痛，也不使用柴胡来伐肝，因为产妇体内虚弱。
Postpartum strangury (dysuria with frequency and urgency) is also caused by yin deficiency generating internal heat due to excessive blood loss. The Kidney is the organ of extreme yin, governing the water pathways. Excessive blood loss leads to a deficiency of true yin, thus generating internal heat, causing urine to become strangury with astringency and pain. This is because heat pathogen lodges in the bladder (paom), where deficiency causes frequent urination and heat causes astringency and pain. If both qi and blood are combined with heat, and blood enters the uterus (baozhong), blood will follow the urine and be discharged as bloody strangury (xuelin). However, urinary retention and obstruction must be treated differently from strangury. Retention belongs to qi deficiency, whereas strangury belongs to internal heat causing astringency and pain. Therefore, Mizhai treats strangury using Zhiku Daochi San (Anemarrhena and Phellodendron Decoction for Guiding Out Heat from the Heart) and Tiao Yiyuan San (Powder for Regulating and Benefiting the Origin). Feng Shi stated: In cases of blood deficiency with heat stagnation, Liuwei Wan (Six-Ingredient Pill with Rehmannia) and Xiaoyao San (Free and Easy Wanderer Powder) should be used to tonify yin and nourish blood, nourishing the source of transformation, assisted by herbs that guide blood.
Zhiku Daochi San (Anemarrhena and Phellodendron Decoction for Guiding Out Heat from the Heart)
Shengdi Huang (Radix Rehmanniae Preparata), Chishao Yao (Radix Paeoniae Rubra), Mutong (Caulis Akebiae), Maidong (Rhizoma Ophiopogonis, heart removed), Huangbai (Cortex Phellodendri), Zhimu (Rhizoma Anemarrhenae, stir-fried), Guixin (Cortex Cinnamomi), Gancao (Radix Glycyrrhizae) (each 1 qian); Dengxin (Junci Medulla) (49 cun).
Postpartum hematuria accompanied by lower abdominal pain is caused by failed blood flowing into the bladder; if there is no lower abdominal pain but only astringency and pain during urination, it is due to internal heat. Both conditions are primarily treated with Xiaoji Tang (Small Thistle Decoction). *Zunsheng* uses Jiawei Shenqi Wan (Modified Kidney Qi Pill), removing Rougui (Cortex Cinnamomi) and Fuzi (Radix Aconiti Lateralis Preparata), adding Shengdi Huang (Radix Rehmanniae Preparata) and Fazhui (Ash of Hair). As for hematochezia (blood in stool), it may be due to improper diet and lifestyle, or due to excess of the six climatic pathogens (liuyin) and seven emotions (qieqing), leading to damage of primordial qi and injury to the yin collaterals. It is treated with Sijunzi Tang (Four Gentlemen Decoction) plus Shengdi Huang (Radix Rehmanniae Preparata), Shengma (Rhizoma Cimicifugae), Guishen (Radix Angelicae Sinensis), Baishao Yao (Radix Paeoniae Alba), and Fazhui (Ash of Hair).
Xiaoji Tang (Small Thistle Decoction)
Xiaoji Gen (Radix et Rhizoma Cirsii Japonici), Shengdi Huang (Radix Rehmanniae Preparata), Chishao Yao (Radix Paeoniae Rubra), Mutong (Caulis Akebiae), Puhuang (Pollen Typhae), Danzhuye (Folium Lophatheri), Gancaoshao (Radix Glycyrrhizae, tip) (each 1 qian); Huashi (Talcum) (2 qian); Dengxin (Junci Medulla) as guiding herb.
Within seven days postpartum, cough caused by external contraction of wind-cold, with nasal congestion, heavy voice, and aversion to cold, can heal itself by taking Shenghua Tang (Generate the New Decoction) alone, as it contains Xiong (Rhizoma Chuanxiong) and Jiang (Rhizoma Zingiberis Recens) to disperse the pathogen. Alternatively, Xingren (Semen Armeniacae Amarum) and Jiegeng (Radix Platycodonis) can be added to Shenghua Tang. If phlegm is present, add Tianhuafen (Radix Trichosanthis). Jiawei Shenghua Tang (Modified Generate the New Decoction) is also used for these conditions. Generally, Mahuang (Herba Ephedrae) is not used to induce sweating, and even if cough is accompanied by hypochondriac pain, Chaihu (Radix Bupleuri) is not used to subdue the Liver, because the interior is deficient.
