Night sweating refers to sweating during sleep and stopping after waking up. Night sweating is often caused by heat in the body or by yin deficiency and fire, and in addition to the symptoms of sweating at night and stopping when waking up, there are also symptoms such as afternoon hot flashes, inner irritability, insomnia, heat in the hands and feet, as well as dizziness and tinnitus. From a western medical point of view, night sweats may be due to malnutrition, lack of trace elements such as zinc and calcium in the body, resulting in disorders in the body’s sweat metabolism, which can be caused by irregular daily routine. In the case of night sweats caused by yin deficiency and fire exuberance, the treatment of nourishing yin and lowering fire can be done by taking Zhi Bo Di Huang Wan and Dang Gui Liu Huang Tang to relieve the symptoms. Night sweats caused by excessive heat should be treated by clearing liver heat and lowering heart fire, taking Scutellaria baicalensis, Gardenia jasminoides and Gentian diarrhea of the liver soup.
