产后七日内外出现发热，其证候表现多种多样，除了伤食引起的发热已在“伤食门”中论述过之外。然而还有发热、恶寒、头痛类似太阳病（太阳经受邪所致的病证）的症状，或者寒热往来、头痛、胁痛类似少阳病（少阳经受邪所致的病证）的症状，这些皆因气血两虚、阴阳不和所致，其症状颇像伤寒，治疗者切勿偏执一端。因为产后大血空虚，一旦使用发汗法，重则导致亡阳（阳气暴脱），轻则引起筋惕肉瞤（肌肉跳动）、郁冒昏迷，或抽搐、便秘，变症百出。虽然明知感受了外邪，但在生化汤（促进子宫复旧、化瘀生新的方剂）内的川芎、干姜也能起到发散作用，否则也可单独使用辛散生化汤。何必用发表药去触犯不可发汗的禁忌呢？产时用力过度导致的发热，失血过多导致的发热，恶露排出不畅导致的发热，产后三日蒸乳（乳汁分泌旺盛期）导致的发热，过早起床劳动导致的发热，多因血虚导致阳气无所依附，浮散于体表而表现为发热，只需服用二至三剂生化汤，去除恶露、生成新血，阳气生发、阴血增长，各种热象都能消退。《尊生》采用丹溪（朱震亨）的方法，用四君子汤（补气基础方）加川芎、当归、黄芪、炮姜，治疗产后发热，也是甘温除大热（用甘温药物治疗气虚发热）的意思。

产后大便燥结秘滞，是由于失血过多，胃中干燥，精微物质不能向下输送，以致糟粕壅滞不通。况且大肠主津液，产妇体内津液亡失，则干枯失去传导变化的功能，所以导致排便困难。多服用生化汤，则血液充盈、气机顺畅，自然润通；或者服用养正通幽汤（滋养正气、通便开窍的方剂）也可以。如果不大便但没有其他痛苦，即使不服药也可以；即使有类似伤寒三阴病（太阴、少阴、厥阴病证）的症状，如潮热汗出，或口燥腹满，或谵语（胡言乱语）、便秘，燥屎宜下的等症，这其实是气血枯竭，虚证类似实证，切勿妄议使用三承气汤（峻下热结的方剂）来攻下。冯氏说：大便困难，只适宜调理中焦、养血，切不可单用麻仁、枳壳，徒然耗损肠胃中生养之气而无功效。有的治疗大便日久不通，大量使用川芎、当归，服至见效，方才取得疗效，同时兼服润肠粥。如果大小便都秘结，恶露不行，方论均见“恶露不下门”。

Within seven days before and after childbirth, fever may occur with various manifestations. Besides fever caused by food stagnation, which has been discussed in the section on Food Stagnation, there are cases where fever, aversion to cold, and headache resemble Taiyang disease (disease syndrome of the Taiyang channel), or alternating chills and fever, headache, and hypochondriac pain resemble Shaoyang disease (disease syndrome of the Shaoyang channel). All these are due to deficiency of both Qi and Blood, and disharmony of Yin and Yang. The symptoms closely mimic Shanghan (Cold Damage), so practitioners must avoid biased treatment. Since postpartum blood is largely depleted, if sweating methods are used, severe cases may result in Yang collapse (sudden loss of Yang Qi), while mild cases may cause muscle twitching, depression and dizziness with coma, convulsions, and constipation, leading to numerous complications. Although it is known that external pathogens are involved, Xiong (Ligusticum Chuanxiong Rhizome) and Jiang (Zingiberis Rhizoma) within Shenghua Tang (Decoction for Generating New Blood) can also disperse them; otherwise, Xin San Shenghua Tang (Pungent-Dispersing Shenghua Decoction) can be used alone. Why use exterior-releasing drugs to violate the prohibition against sweating? Fever due to excessive exertion during delivery, fever due to excessive blood loss, fever due to sluggish lochia discharge, fever during the third day when milk secretion increases (milk steaming), and fever due to getting out of bed and working too early are mostly caused by Blood deficiency, leaving Yang without a foundation, floating and scattering externally as heat. Simply taking two or three doses of Shenghua Tang to eliminate lochia and generate new blood, allowing Yang to grow and Yin to increase, will resolve all fevers. Zunsheng adopted Danxi's method, using Sijunzi Tang (Four Gentlemen Decoction) added with Xiong (Ligusticum Chuanxiong Rhizome), Danggui (Angelicae Sinensis Radix), Huangqi (Astragali Membranacei Radix), and Paojiang (Prepared Zingiberis Rhizoma) to treat postpartum fever, embodying the principle of using sweet-warm herbs to remove great heat (treating Qi-deficiency fever with sweet-warm properties).

Postpartum dry and constipated stool results from excessive blood loss causing dryness in the Stomach, preventing essence and nutrients from descending, leading to obstruction of waste materials. Moreover, the Large Intestine governs fluids; when the puerpera loses internal fluids, dryness causes loss of its conducting and transforming functions, resulting in difficult defecation. Frequent intake of Shenghua Tang will enrich Blood and smooth Qi, naturally moistening and unblocking the bowels; alternatively, Yangzheng Tongyou Tang (Nourishing Righteousness and Opening Obstruction Decoction) can be taken. If there is no bowel movement but no discomfort, medication may not be necessary. Even if symptoms resemble Shaoyin, Taiyin, or Jueyin diseases of Shanghan (such as tidal fever with sweating, dry mouth and abdominal fullness, delirium, constipation, or need to purge dry feces), these are actually signs of exhaustion of Qi and Blood, where deficiency mimics excess. Practitioners must not rashly prescribe Chengqi Decoctions (Three Generals' Decoctions for purging heat and accumulation) to purge. Feng stated: For difficult defecation, only regulating the Middle Jiao and nourishing Blood is suitable; one must not solely use Hemp Seed (Cannabis Fructus) and Aurantium Fructum Immaturum, which merely deplete the generating Qi of the intestines and stomach without effect. Some treatments for prolonged constipation use large doses of Chuanxiong and Danggui until efficacy is achieved, accompanied by intestinal-moistening porridge. If both urine and stool are obstructed and lochia does not flow, see the section on "Lochia Not Flowing."
