The "Five Tinea" (Wu Xuan) refers to damp tinea, stubborn tinea, wind tinea, horse tinea, and cow tinea. (Both scabies and tinea are caused by heat and dryness in the blood level, leading to wind-toxin attacking the skin. Lesions that are superficial are called scabies, while those that are deep-seated are called tinea. Scabies is often accompanied by heat, whereas tinea is often accompanied by dampness.)
Fangfeng Tongsheng San (Saposhnikovia Universal Relief Powder): Treats tinea and scabies. Remove Mangxiao (Mirabilite) and Dahuang (Rhubarb) from the formula, and add Fuping (Duckweed) and Zaojiaoci (Gleditsia Spine). (See the "Stroke" chapter for the full formula details.)
