Forehead sweating is divided into three causes: 1, damp-heat, forcing the fluid out, that is, damp-heat in the body will force sweat, flowing from the head; 2, deficiency of righteousness, Qi deficiency, not able to collect sweat; 3, vegetative Ying and Wei is not regulated, Ying and Wei disorder resulting in sweating. For the first type of damp-heat, we will have damp-heat related symptoms, such as liver and gallbladder damp-heat, which will have bitter mouth, dry mouth, and irritable mood; spleen and stomach damp-heat will have sticky stools, sticky mouth, and abdominal distension after eating, which requires clearing the liver and gallbladder or cleaning the spleen and stomach damp-heat. If for Qi deficiency, usually weakness and tiredness, sweating when moving, poor appetite, memory loss, or even heavier symptoms of Qi deficiency, we can usually take Huang Qi water in infusion or use Yu Ping Feng San to improve Qi deficiency sweating. As for the Ying and Wei disorder, it is usually the case that there has been a wind-cold cold or frequent sweating from the wind, resulting in the evil Qi right on the muscle surface, not entering the inside and not leaving the outside. In this case we can use the form of sweating to relieve the muscle, such as using Gui Zhi Tang, where Gui Zhi, Bai Shao, ginger and jujube are boiled into a bowl of soup and drunk continuously for several days to send out the sweat, which will carry the evil qi out of the coup and out of the muscle surface and also improve some symptoms.
