病源干癣但有匡郭，皮枯索，痒搔之白屑出，是也，皆是风湿邪气客于腠理，复值寒
湿与血气相搏所生，若其风毒瓦斯多，湿气少，故风沉入深，故无汁为干癣，其中生虫。
又湿癣者，亦有匡郭，如虫行侵淫赤湿，痒搔之，多汁成疮，是其风毒瓦斯浅，湿多风少
，故为湿癣也，其中亦有虫。（出第三十五卷中）

Disease Origin: The characteristic of Gan Xuan (Dry Tinea) is that it has only a defined border, the skin is dry and rough, and scratching causes white scales to fall off. This is caused by Wind-Dampness pathogenic factors invading the Cou Li (interstices of skin and muscles), combined with Cold-Dampness clashing with Blood and Qi. If the Wind-Toxic Qi is abundant while Dampness is scarce, the Wind pathogen sinks deeply, resulting in no exudate; this is called Gan Xuan (Dry Tinea), and insects may breed within it.
Furthermore, Shi Xuan (Wet Tinea) also has a border, spreading like insect movement, with redness, swelling, and dampness at the lesion. Scratching causes fluid discharge forming sores. This occurs because the Wind-Toxic Qi is superficial, with abundant Dampness and scarce Wind, hence it is called Shi Xuan (Wet Tinea), and insects may also breed within it. (From Volume 35)
Zhou Hou Fang (Elbow Reserve Essential Formulas) treats Zao Xuan (Dry Tinea).

Shen Shi Fang (Deep Master's Formulas) divine formula for Gan and Shi Xuan.
