Hot flashes (flashes of heat) need to be identified before treatment. The causes of hot flashes may be Yangming internal organs, yin deficiency and fire (deficiency of yin and essence in the body, resulting in hyperactive fire), dampness and warmth (warmth caused by feeling dampness and heat), and stasis of blood and heat (when evil qi stays for too long, it is transformed into heat), and so on. Yangming tidal fever is common in the afternoon from 3:00 to 5:00 p.m. when the fever is obvious and high, often accompanied by thirst, cold drinks, abdominal distension, constipation and other symptoms. It can be treated with medicines such as regulating stomach and Chengqi Tang, Da Chengqi Tang, Xiao Chengqi Tang, and so on. Yin deficiency hot flashes can be seen in Yin deficiency and fire exuberance syndrome, which is a low-grade fever that occurs in the afternoon and at night, accompanied by zygomatic redness (reddish color of cheeks and zygomatic bones), night sweating (abnormal sweating after falling asleep, but sweating stops after waking up), and five heart-quenching heat (heat in the hearts of the hands and feet, and self-consciousness of heart and chest heat), and in severe cases, it is called bone vaporizing hot flashes (a burst of heat, and the feeling of heat penetrating outward from inside the bones). This can be treated with Zhi Bai Di Huang Wan, Angelica Sinensis Liu Huang Tang, or Da Yao Yin Wan. Damp-warm damp-heat is seen in Damp-Warm Disease, which manifests itself as heat in the afternoon, head and body heaviness (a feeling of heaviness in the head and limbs), and body heat that does not rise (a feeling of heat all over the body, but not much heat when touching the skin). This can be treated with San Ren Tang. If blood stasis has accumulated for a long period of time, and the stagnation of blood has turned into heat, there will be heat in the afternoon and at night. This can be treated with Hematopoietic Blood Stasis Tang. The adverse effects and contraindications of the above herbs are not clear, so do not use them privately. If you have a hot flash, it is recommended that you consult a doctor in time to avoid delaying your condition.
