产后 疟，在初产时绝少。即胎前久疟淹缠，产后里气通达，无不霍然。即有半月内外寒热往来，
每日应期而发，或一日二三度，其证类疟，皆由产后气血虚损，阳虚作寒，阴虚发热。或昼轻夜重，
或日哺发热，或有汗，或头有汗而不及身足，此乃元气虚弱，孤阳绝阴之证，俱宜滋荣益气扶正汤，间
服六味丸，以退寒热。如寒热往来，头痛无汗，加减养胃汤治之。若寒热已久无汗者，兼煎参术膏，
以助养胃汤药力。慎不可作疟治而用柴胡汤，及芩、连、栀、柏以退热，草果、槟、常以绝疟而误人也。
至于阴阳不和，乍寒乍热，参归汤治之。《全书》云∶阴胜寒多，理阴煎。阳胜热多，三阴煎。阳气陷
入阴中，补阴益气煎。阴阳俱虚，八珍、十全。败血不散，流入阴中而作寒热，决津煎、殿胞煎。

Malaria occurring postpartum is extremely rare immediately after childbirth. Even if the patient suffered from chronic malaria during pregnancy, once the internal qi becomes unobstructed after delivery, recovery is almost instantaneous. In cases where chills and fever alternate for about half a month, occurring daily at specific times or two to three times a day with symptoms resembling malaria, these are caused by deficiency and damage of qi and blood postpartum. Yang deficiency leads to cold sensations, while yin deficiency leads to fever. Some patients experience milder symptoms during the day and heavier ones at night; some have fever in the late afternoon; some sweat profusely; some only sweat on the head without sweating on the body or feet. These constitute syndromes of weak primordial qi and isolated yang with absolute yin deficiency. All such cases should be treated with Zirong Yiqi Fuzheng Tang (Nourishing Blood and Boosting Qi to Support Uprightness Decoction), taken intermittently with Liuwei Wan (Six-Ingredient Pill), to alleviate chills and fever. If chills and fever alternate accompanied by headache and absence of sweating, Jiajian Yangwei Tang (Modified Stomach-Nourishing Decoction) should be used. For prolonged chills and fever without sweating, Shenhu Gao (Ginseng and Atractylodes Paste) can be decocted concurrently to enhance the efficacy of Yangwei Tang. One must strictly avoid treating this as malaria using Chaihu Tang (Bupleurum Decoction), or employing Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Zhizi (Gardeniae Fructus), and Huangbai (Phellodendri Cortex) to reduce heat, or Caoguo (Tsaoko Fructus), Binglang (Arecae Semen), and Changshan (Dichroae Radix) to arrest malaria, as this would lead to medical error. Regarding disharmony of yin and yang causing alternating chills and fever, Shengu Tang (Ginseng and Angelica Decoction) is indicated. The *Quan Shu* states: When yin predominates leading to excessive cold, Liyin Jian (Yin-Regulating Infusion) is used; when yang predominates leading to excessive heat, Sanyin Jian (Three-Yin Infusion) is used; when yang qi sinks into yin, Buyin Yiqi Jian (Tonifying Yin and Boosting Qi Infusion) is used; when both yin and yang are deficient, Bazhen Tang (Eight-Treasure Decoction) or Shiquan Dabu Tang (Ten-Ingredient Great Tonifying Decoction) are used; when stagnant blood fails to disperse and flows into yin causing chills and fever,iejuejin Jian (Juejin Infusion) or Dianbao Jian (Dianbao Infusion) are used.

This is a modified formula of Buzhong Yiqi Tang (Tonify the Middle and Boost Qi Decoction), treating injury to yin from overwork, failure of essence to transform into qi, yin deficiency with external contraction of malaria, and constipation. It is effective for ascending and dispersing in cases of insufficient yin qi with invasion by deficient pathogens.
