回答：阴阳失调，以及恶露（产后残留的瘀血）停滞不散，都会导致忽冷忽热的症状。产妇气血虚弱亏损，造成阴阳失调。阴气偏胜则出现忽冷，阳气偏胜则出现忽热。阴阳相互偏胜，所以时而发冷时而发热。如果是因分娩劳累损伤了脏腑，血液虚弱不能正常宣通发散，从而导致恶露停滞不散。如果恶露进入肺脏则表现为发热，进入脾脏则表现为发冷。医生如果错误地当作疟疾来治疗，就错了。对于阴阳失调引起的症状，适宜使用增损四物汤；对于恶露停滞不散引起的症状，适宜使用夺命丹。又问：如何区分这两种情况？回答是：如果伴有阵发性刺痛，属于恶露停滞；如果只是单纯的忽冷忽热而没有其他症状，属于阴阳失调。

Answer: Disharmony of Yin and Yang, and the failure of lochia (residual blood after childbirth) to disperse, both cause alternating chills and fever. After childbirth, Qi and Blood are deficient and damaged, leading to disharmony of Yin and Yang. When Yin prevails, there is alternating chills; when Yang prevails, there is alternating fever. As Yin and Yang mutually prevail, one experiences either chills or fever. If this is caused by labor during childbirth damaging the Zang-Fu organs, causing Blood deficiency and preventing its proper circulation and diffusion, thus resulting in the stagnation of lochia. If lochia enters the Lung, it causes heat; if it enters the Spleen, it causes cold. It is erroneous for physicians to mistakenly treat this as malaria (Malaria). For symptoms due to disharmony of Yin and Yang, Zengsun Siwu Tang (Modified Four Substances Decoction) is appropriate; for symptoms due to the failure of lochia to disperse, Duoming Dan (Life-Restoring Pill) is appropriate. Further question: How can these two be distinguished? Answer: If accompanied by paroxysmal stabbing pain, it is due to lochia stagnation; if there is only alternating chills and fever without other symptoms, it is due to disharmony of Yin and Yang.
