论述说：寒热往来，是阴阳虚实相互偏胜的结果。阴气实盛则产生内寒，阳气虚衰则产生外寒，这都属于阴胜阳衰；阳气实盛则产生外热，阴气虚衰则产生内热，这都属于阳胜阴衰。阴阳相互偏胜，所以寒热交替发作、往来不定。治疗原则应当使阴阳恢复平衡，气机不再相互偏胜，那么疾病就可以痊愈。

Discourse states: Alternating chills and fever (Han Re Wang Lai) is the result of Yin and Yang, deficiency and excess, mutually prevailing. When Yin is solid/excess, internal cold (Nei Han) arises; when Yang is deficient, external cold (Wai Han) arises; both are cases of Yin prevailing over Yang. When Yang is solid/excess, external heat (Wai Re) arises; when Yin is deficient, internal heat (Nei Re) arises; both are cases of Yang prevailing over Yin. Because Yin and Yang prevail against each other, chills and fever alternate and come and go. The treatment principle should aim to bring Yin and Yang into harmony, so that Qi does not prevail excessively against itself, then the disease can be cured.
