四物汤（见肠痒）五味异功散（即六君子除半夏，载血晕）十全大补（见玉门不闭）。
黄 补血汤
嫩黄 （一两） 当归（三钱）
水煎服。
生化汤（见前）理中汤（载后腹痛）
清魂散
荆芥穗（一钱炒黑色） 当归（五钱）
作一服为末，生姜汤调下，或加川芎（一钱），煎服亦可（此方退风，并惊风搐搦俱妙）。
产妇发热，原因是血虚，适宜用四物汤加黑姜（炒焦的干姜），以苦温之法治疗，热势自然消退。如果无效，再加入少许童便（儿童尿液）冲服，热势自然会退去。但童便性寒，不可多用。又有因脾虚伤食而发热的，也有因胃虚发热的，治法应当调理饮食，理顺脾胃，使用五味异功散来补益。如果是伤食，加神曲、谷芽。更有出现躁热、面目赤红、心烦口渴想喝水的症状，脉象洪大，重按却完全无力，这是极度虚弱导致的假热，适宜服用当归补血汤，病情重的用十全大补汤，或者再加附子，收敛浮散的阳气，热势必然自退。如果误诊为风热，一用凉散的药物，没有不立刻见到危险的，这难道不是医生杀死了病人吗？
郭稽中说：产后出现忽冷忽热的症状，很常见，不可以当作疟疾来治疗。大概都是由于营卫空虚，阴阳不和，或者是败血（瘀血）为害，或者是脾胃虚弱。这话非常明白事理，可惜很多行医的人不能明察。大凡风寒引起的发热，昼夜都不退去，适宜在生化汤中加入黑荆芥一味药，足可以驱除邪气。因为产后身体虚弱，关节开张，腠理（皮肤毛孔及纹理）不坚固，容易受邪也容易出邪，这是小贼，不比伤寒需要用刀兵强力的手段驱盗。如果是血虚与伤食，则会在下午申时左右发热，清晨必定退去，这两个症状虽然相似，其中仍有分辨之处。伤食的，一定伴有嗳气腐臭、吞酸、胸膈满闷，频饮谷芽陈皮汤可以痊愈；血虚的，则没有上述那些现象，只可用四物汤加炮姜，可以退热。
如果出现呕吐、腹泻不利、腹痛、食欲少，脉象沉细而迟，或者浮大而中空，适宜用理中汤温补。寒证热证、虚证实证，如果不辨明清楚，怎么能不出错呢？我看浙江地区，往往死守钩藤、秦艽，或者稍微有点寒热症状，就用柴胡，这些都不是产后病人所能承受的。我也学识浅薄，怎敢谈论别人的过错，不过是遵守前贤的训诫，或许可以避免让枉死者告冤吧。

Postpartum fever, caused by blood deficiency, is suitable for treatment with Siwu Decoction (Four Substances Decoction) added with Heijiang (charred dried ginger), using a bitter-warm method, after which the fever will naturally subside. If there is no response, add a small amount of Tongbian (child's urine) to take orally, and the fever will naturally recede. However, Tongbian is cold in nature and should not be used in large quantities. There are also cases of fever due to spleen deficiency and food stagnation, as well as those due to stomach deficiency. The treatment method should involve regulating diet and harmonizing the spleen and stomach, using Wuyi Yigong San (Five-Ingredient Powder for Strengthening the Spleen) for tonification. In cases of food stagnation, add Shenqu (Medicated Leaven) and Guya (Sprouted Grain). Furthermore, there are cases of restless heat, redness of the face and eyes, irritability, thirst with a desire to drink, where the pulse is surging and large but completely empty upon deep pressure; this is false heat due to extreme deficiency, suitable for taking Danggui Buxue Tang (Danggui Tonifies the Blood Decoction). For severe cases, Shiquan Dabu Tang (Ten Complete Great Tonifying Decoction) may be used, or Fuzi (Aconite Lateral Root) may be added to gather the floating and scattered Yang qi, after which the heat will surely recede. If mistakenly diagnosed as wind-heat and treated with cooling and dispersing herbs, danger will appear immediately without exception; is this not killing the patient by medical error?
Guo Jizhong stated: Postpartum alternating chills and fever occur frequently and should not be treated as malaria. It is generally due to emptiness of Ying (Nutritive Qi) and Wei (Defensive Qi), disharmony of Yin and Yang, harm from Baixue (stagnant blood), or deficiency of the spleen and stomach. This statement is extremely clear and reasonable; it is unfortunate that many practitioners fail to observe this clearly. Generally, fever caused by wind-cold persists day and night without abating; it is suitable to add Heijingjie (charred Schizonepeta Spike) to Shenghua Tang (Generate the New Decoction), which is sufficient to expel the pathogen. Because the postpartum body is deficient, joints are open, and Couli (skin pores and interstices) are insecure, pathogens easily enter and exit; this is like a petty thief, unlike the use of military force to drive away robbers in Shanghan (Cold Damage) disease. If it is blood deficiency combined with food stagnation, fever occurs around the Shen hour (3-5 PM) and must recede by early morning; although these two conditions seem similar, they can still be distinguished. In cases of food stagnation, there must be belching with a putrid odor, acid regurgitation, and fullness/stuffiness in the chest and diaphragm, which can be cured by frequently drinking Guya Chenpi Tang (Sprouted Grain and Tangerina Peel Decoction); in cases of blood deficiency, the aforementioned symptoms are absent, and only Siwu Decoction added with Paojiang (prepared ginger) can be used to reduce the fever.
If accompanied by vomiting, difficult defecation, abdominal pain, and poor appetite, with a pulse that is deep, fine, and slow, or floating, large, and empty, Lizhong Tang (Regulate the Middle Decoction) should be used for warming and tonifying. If cold and heat, deficiency and excess are not clearly differentiated, how can errors be avoided? I have observed that in Zhejiang, practitioners often rigidly adhere to Gouteng (Uncaria Ramulus cum Uncis) and Qinjiao (Gentiana Macrophylla Root), or if there is slight chills and fever, immediately use Chaihu (Bupleuri Radix); none of these are suitable for postpartum patients. My learning is shallow, how dare I discuss others' faults? I merely follow the instructions of former sages, perhaps avoiding complaints from the wrongfully dead.
