【附论】
湿癣也有其特定的形态特征。症状如同虫子在皮肤下爬行，患处浸润、发红、潮湿，伴有瘙痒。抓挠后流出汁液并形成疮疡。这是因为风毒之气攻注于肌肤所致，所以称为湿癣。

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.
