Discussion states: What is the cause of alternating chills and fever after childbirth? The answer is: Disharmony of Yin and Yang, and failure of stagnant blood to disperse can cause alternating chills and fever. After childbirth, Qi and Blood are deficient and damaged, leading to disharmony of Yin and Yang. If Yin prevails, there is sudden chills; if Yang prevails, there is sudden fever. When Yin and Yang contend with each other, chills or fever occur alternately. If this results from labor injuring the Zang-Fu organs during delivery, causing weak Blood that cannot circulate freely, it leads to stagnant blood failing to disperse. If stagnant blood enters the Lung, heat occurs; if it enters the Spleen, cold occurs. If physicians mistakenly treat this as malaria, it would be erroneous. For disharmony of Yin and Yang, Zengsun Siwu Tang (Modified Four Substances Decoction) is appropriate; for stagnant blood failing to disperse, Mingdan (Life-Restoring Pill) is appropriate. Another question asks how to distinguish between the two? The answer is: Intermittent stabbing pain indicates stagnant blood; chills and fever without other symptoms indicate disharmony of Yin and Yang. There are various variations of Zengsun Siwu Tang, all modified according to the specific condition.

Renshen (Ginseng Root), Danggui (Angelica Sinensis Root), Shaoyao (Peony Root), Chuanxiong (Ligusticum Rhizome), Ganjiang (Dried Ginger Rhizome), each 1 liang; Gancao (Licorice Root), 4 qian in weight.
Crush the herbs. Take 4 qian per dose. Use one zhan of water and three slices of ginger. Decoct until reduced to 70%, remove the dregs, and take hot. No specific time restriction.
Commentary states: Alternating chills and fever indicate disharmony of Ying and Wei (Nutritive and Defensive Qi), which is difficult to judge lightly. If it is due to stagnant blood failing to disperse, does it only affect the Spleen and Lung? Generally, when one Yin obstructs one Yang, chills and fever manifest. Prevailing Yin causes cold; prevailing Yang causes heat. It can only be said that stagnant blood flows along the meridians; obstructing the various Yins causes cold, while obstructing the various Yangs causes heat. The condition ceases when Blood/Qi harmonizes with Wei Qi, but recurs upon their next convergence. Dajiao Jing San (Great Menstrual Regulation Powder) and Wuji San (Five Accumulations Powder) are best decocted with vinegar.
