First, let's look at heat generated by Yin deficiency. The Yin and Yang within our bodies must remain in balance. If the Yin fluids in the body are depleted and can no longer restrain the Yang, it leads to hyperactivity of Yang Qi, resulting in "deficiency fire" (Xu Huo). This occurs most easily in the Liver and Kidney organs. Primary manifestations include afternoon tidal fever, heat in the palms and soles, restlessness in the "five hearts" (palms, soles, and chest), and night sweats. In such cases, it is necessary to nourish Kidney Yin; Zhibai Dihuang Wan may be considered for reference.

Next is heat generated by Qi deficiency. This specifically refers to Spleen Qi deficiency. Traditional Chinese Medicine holds that Spleen deficiency generates Dampness. Since the nature of Dampness is heavy, turbid, and sticky, it tends to move downward, obstructing the ascending Kidney Yang. When Kidney Yang encounters Dampness, it easily becomes stagnant and transforms into fire, producing dryness and heat. This manifests as morning fever or a sensation of dry heat upon slight physical exertion. Furthermore, when Qi is deficient, its function of consolidating body fluids weakens, leading to excessive sweating. At this time, it is necessary to strengthen the Spleen, supplement Qi, and raise the "Clear Yang"; Buzhong Yiqi Wan may be considered for reference.

Finally, blood deficiency can also generate heat. Traditional Chinese Medicine (TCM) posits that blood belongs to Yin. Chronic blood deficiency leads to insufficient Yin-blood, which lacks the strength to restrain Yang-Qi, thereby causing blood deficiency fever. The primary manifestations include dizziness, blurred vision, general fatigue, a pale complexion, and pale lips and nails. In such cases, it is necessary to supplement Qi and nourish the blood; one may refer to the modified use of Gui Pi Tang.

However, please be reminded that Traditional Chinese Medicine (TCM) medication requires syndrome differentiation; if you have any health concerns, please consult a professional physician promptly for diagnosis, treatment, and conditioning.
