Source text 原文

Donguibogam 東醫寶鑑

治陰囊生瘡出水, 其痒甚苦, 搔之無足, 後必自痛. 牡蠣粉ㆍ黃丹各二兩, 枯白礬四兩. 爲末, 遇夜用手撿藥於痒處擦之, 連擦三四次自然平復. 《入門》

Translation

Treats sores on the scrotum running water, with an itch so bitter that scratching is never enough and pain follows after. Oyster shell powder and red lead 2 nyang each; calcined alum 4 nyang. Powder them, and at night take the medicine up in the hand and rub it on the itching place; rub three or four times running and it comes right of itself. — Uihak Immun 入門 (Donguibogam · Jeoneum)

Clinical commentary 臨床

搔之無足, 後必自痛 — scratching is never enough, and pain follows. The itch-scratch cycle of scrotal eczema described exactly, and 4.25 keeps a section for it. **Contains red lead, which is toxic. For external use only.** — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
