In the book of “The meridians and veins”: “Therefore, if you eat and drink, sweat out of the stomach; if you are frightened and take away the essence, sweat out of the heart; if you hold heavy and travel far, sweat out of the kidneys; if you walk fast and fear, sweat out of the liver; if you shake your body in labor, sweat out of the spleen”, and in the Qing Dynasty. Wang Yanchang, “Wang’s Medical Cun? That is, the sweat place to know its deficiency” said: “five organs have sweat, not only the heart. Sweat is all deficient. Heart deficiency is head sweat, liver deficiency is spine sweat, kidney deficiency is sac sweat, lung deficiency is chest sweat, spleen deficiency is hand and foot sweat. If you are weak and sweat in one place, you will not heal for a long time, that is, this is the deficiency of the five organs.
