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.

The *Neijing* states: "All pain, itching, and ulcerations belong to Heart Fire." Although this is also caused by accumulated heat-toxin in the five zang organs, combined with blood deficiency and wind-dampness. There are five types of scabies: dry, wet, insect, sand, and pus.

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.
