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，其症类疟，皆由产后气血虚损，阳虚作寒，阴虚发热，或昼
轻夜重，或日晡发热，或有汗，或头有汗而不及身足。此乃元气虚弱，孤阳绝阴之症。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，决阴煎、殿胞煎。

Postpartum malaria is extremely rare immediately after childbirth. Even if the patient suffered from chronic malaria during pregnancy, once in the postpartum period, as the internal qi becomes unobstructed, recovery is invariably swift and complete. However, within half a month after delivery, some women may experience alternating chills and fever (alternating cold and heat), occurring daily at specific times, or two to three times a day, with symptoms resembling malaria. These conditions are all caused by deficiency and depletion of qi and blood after childbirth: yang deficiency generates cold, while yin deficiency generates heat. Symptoms may be lighter during the day and heavier at night, or feature fever in the afternoon (specifically around the Shen hour). There may be generalized sweating, or sweating only on the head without extending to the body or feet. This constitutes a syndrome of weak primordial qi, characterized by isolated yang and absent yin. All such cases should be treated with Zirong Yiqi Fuzheng Decoction (Nourishing Blood and Replenishing Qi to Support Uprightness Decoction), taken intermittently alongside Liuwei Wan (Six-Ingredient Rehmannia Pill) to resolve the alternating chills and fever. If accompanied by headache and absence of sweating, Jiajian Yangwei Tang (Modified Stomach-Nourishing Decoction) should be used. If the alternating chills and fever have persisted for a long time and there is no sweating, Shenzhu Gao (Ginseng and Atractylodes Paste) should be decocted concurrently to enhance the efficacy of the Yangwei Tang. One must strictly avoid treating this as malaria; using Chaihu Tang (Bupleurum Decoction) along with Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Zhizi (Gardeniae Fructus), and Huangbai (Phellodendri Cortex) to reduce heat, or Caoguo (Tsaoko Fructus) and Binglang (Arecae Semen) to arrest malaria, will lead to fatal errors. For cases of yin-yang disharmony presenting with intermittent chills and fever, Shengu Tang (Ginseng and Angelica Decoction) is indicated. The *Quan Shu* states: When yin predominates, resulting in more cold, Liyin Jian (Yin-Nourishing Decoction) is used; when yang predominates, resulting in more heat, Sanyin Jian (Three Yin Decoction) is used; when yang qi sinks into the yin, Buyin Yiqi Jian (Tonifying Yin and Replenishing Qi Decoction) 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. If stagnant blood fails to disperse and flows into the yin causing chills and fever, Jueyin Jian (Yin-Resolving Decoction) or Dianbao Jian (Uterine-Pacifying Decoction) are indicated.

It is effective for ascending and dispersing in cases of insufficient yin qi and invasion by deficient pathogens.
