《内经》说：“各种疼痛、瘙痒、疮疡，都归属于心火。”虽然这也由五脏蕴积热毒，兼有血虚风湿而引发。疥疮分为五种，即干疥、湿疥、虫疥、砂疥、脓疥。干疥表现为皮肤枯槁干燥且瘙痒；湿疥表现为湿热重、渗液多；虫疥是有传染性，由虫传播；砂疥表现为皮损细小且瘙痒剧烈；脓疥表现为肿胀充满脓疱。治疗应当先服用发汗疏风、凉血解毒、清脏腑热毒的药物，以釜底抽薪（从根本上解决问题）；然后再使用外敷药物。宜选用防风通圣散（方见中风章节），减去芒硝、大黄、枯白矾、白术，加入黄连、黄柏、金银花、苦参煎服。

This type of ulceration takes damp-heat (Damp-Heat) as its root cause and wind-pathogen (Wind Pathogen) as its manifestation. If the pulse is floating and relaxed, accompanied by fever and stiffness/spasms, Modified Baidu San (Jiajian Baidu San) can be used to dissipate various pathogens. If the pulse is deep and solid, with constipation and difficult urination, Fangfeng Tongsheng San (Fangfeng Tongsheng San) can be used to unblock both the exterior and interior. Grinding the medicine into powder for external application is also effective.
External Application Formula: Huashi (Talcum), Huangbai (Phellodendri Cortex) (2 qian each). Grind into fine powder. First, puncture the lesion with a gleditsia sinensis spine, then mix with indigo tinctoria paste (Dianqing) and apply.

Sand scabies presents with minute lesions and severe itching. Pus scabies presents with swelling and pustules. Treatment should first involve administering herbs that induce sweating to dispel wind, cool the blood, resolve toxicity, and clear heat-toxin from the zang-fu organs, thereby removing the root cause; subsequently, use external applications.
