Damp tinea (Shi Xuan) also has specific morphological characteristics. The symptoms feel like insects crawling on the skin; the affected area is infiltrated, red, moist, and itchy. Scratching leads to exudation and the formation of sores. This is caused by the invasion of wind-toxic qi into the skin, hence it is called damp tinea.
