Skin bloating disease name. Insufficient yang, cold staying in the skin, and swelling symptoms. The main symptoms are general swelling, a large abdomen, and thick skin. 'The灵枢·水胀' says: 'Skin swelling, cold qi stays between the skin, the abdomen is large, the whole body is swollen, the skin is thick, pressing on the abdomen does not rise, the abdominal color does not change, this is the sign.' 'The Medicine Remains' says that it is because the vital qi is lost, the虚qi has no place to go, and the cold qi circulates throughout the skin, so there is swelling of the abdomen and the whole body, and the skin is thick. Treatment should be to reinforce the body and expel cold, regulate the qi and transform turbidity, using herbal formulas such as the Expel Cold and Build the Middle汤.
