Spontaneous sweating and night sweating is a disease that is due to the imbalance of yin and yang, and the coup is not solid, resulting in the abnormal leakage of sweat. Not due to the influence of external environmental factors, but sweating at times during the day, and often more, is called spontaneous sweating; sweating during sleep, wake up from the stop is called night sweating. The evidence of spontaneous sweating and night sweating can appear alone or as symptoms in the course of other diseases. Etiology Sweating is a physiological phenomenon of the human body. In hot weather, thick clothing, thirsty for hot soup, emotional excitement, labor and running, etc., sweating increases, which is a normal phenomenon. When you feel the surface evil, sweating is a way to expel the evil. When the external evil is on the surface, sweating is needed to relieve the surface. Sweat is the fluid of the heart, which is made by the essence, so it should not be over-expressed. The pathological changes with increased sweating as the main symptom are mainly caused by the following reasons: 1. Lung Qi deficiency: weakness of the body, weakness of the body after illness, or coughing and wheezing for a long time, depletion of lung Qi. The lungs and the skin, lung Qi deficiency of the person’s muscular surface loose, the surface of the guard is not solid, the coup open leak and cause spontaneous sweating. 2, the Ying and Wei is not and: due to the body of the Yin and Yang of the partial Sheng, partial decline, or table deficiency of people slightly affected by wind evil, so that the Ying and Wei is not and, the Wei outside of the Division, and sweating. 3, Yin deficiency and fire: overwork, loss of blood and essence, or evil heat consumes yin, resulting in deficiency of yin and essence, deficiency of internal fire, yin and essence are disturbed, can not hide themselves and sweat. 4. Evil-heat and vaporization: due to emotional and mental discomfort, liver qi stagnation, liver fire, or addiction to spicy and thick flavors, or damp-heat in the body, resulting in liver fire or damp-heat, evil-heat and vaporization, resulting in increased sweating due to the release of fluids. The identification of class evidence Spontaneous sweating and night sweating should be distinguished from dehiscence, war sweating and yellow sweating. Dehiscence sweating occurs when the condition is critical, when the positive energy is about to be removed, Yang does not converge Yin, resulting in a large release of sweat, manifesting profuse sweating or sweating like pearls, often accompanied by symptoms such as low voice, short breath, mental fatigue, cold extremities, weak pulse or scattered weakness. War sweat occurs in the course of acute fever, the symptoms are fever and thirst, suddenly the whole body shivering, followed by sweating, the fever gradually recede, most of the positive energy to resist the evil, if the positive victory over the evil recede, is the disease tends to improve the image. Yellow sweat is characterized by yellow sweat like cypress juice, staining clothes with color, mostly due to damp heat within. The identification and treatment of spontaneous sweating and night sweating should focus on the identification of yin and yang deficiency and reality. Generally speaking, sweating is mostly due to deficiency, and spontaneous sweating is mostly due to qi deficiency, while night sweating is mostly due to yin deficiency and internal heat. However, if the sweating is caused by liver fire, damp heat and other evil heat, it is a real evidence. Those who have been ill for a long time, or those with heavy lesions, will have a mixture of yin and yang deficiency and reality. Spontaneous sweating for a long time can injure yin, and night sweating for a long time can injure yang, resulting in the evidence of deficiency of both qi and yin, or yin and yang. If the disease is prolonged, it can be seen as a combination of deficiency and reality. The treatment principle is to benefit Qi and nourish Yin, and to consolidate the surface to control sweating; the actual evidence is to clear the liver and drain the heat, and to resolve dampness and Ying; for those with mixed deficiency and reality, it is appropriate to take into account the priority of deficiency and reality. In addition, because spontaneous sweating and night sweating are common pathologies with coup d’état and leakage of fluid, we can add ephedra root, floating wheat, glutinous rice root, Wu Wei Zi, dried bean curd, oyster and other solid and astringent products at our discretion. To enhance the effect of anti-sweating. Spontaneous sweating, night sweating is due to the body’s yin and yang, deficiency, coup not solid, sweat out of the normal cause. Spontaneous sweating is mostly due to Qi deficiency, while night sweating is mostly due to Yin deficiency and internal heat, but those caused by liver fire and damp heat are real evidence. If the disease is prolonged, it can be seen as Qi-Yin deficiency, Yin-Yang deficiency and mixed deficiency-reality evidence. The main treatment method is to benefit the qi and consolidate the surface, harmonize the yin and guard, nourish the yin and lower the fire, and clear the damp-heat. On the basis of the identification of the symptoms, we can strengthen the astringent and astringent sweat products to improve the therapeutic effect.
