Excessive sweating belongs to the category of “sweat syndrome” in Chinese medicine. Excessive sweating may be caused by kidney yin deficiency, or by factors such as evil heat, or the lack of solidity of the lungs and guardians. Kidney deficiency can be categorized into kidney yin deficiency, kidney yang deficiency, and yin and yang deficiency. Kidney yin deficiency may lead to increased sweating, hot flashes, and heat in the hands, feet and heart. Thus, Kidney-Yin deficiency may lead to excessive sweating. However, excessive sweating may also be caused by factors such as emotional and physical weakness, as well as lung and guardian deficiencies, internalization of evil heat, heart and blood deficiencies, etc. Yin deficiency and fire are only one of the types of symptoms, and kidney deficiency is not the only cause of the disease. If the patient persists in excessive sweating, he should go to the hospital, according to the specific symptoms, to determine the type of evidence, and then choose the appropriate drugs for treatment.
