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 of sweat metabolism in the body, and may be caused by irregularities in daily rest and relaxation. 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 Liu Wei Di Huang Wan or Angelica Six Yellow Soup 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.
