Not the eye powder baengnyong-san-an of the Eye chapter and not the ear paste baengnyong-san-i of the Ear chapter: all three carry full compositions and no two share a drug, so this is a third formula of the same name and it takes the chapter tail. The transcription writes 褁, printed here as 裹, the corpus form by 81 places to 32; 煆 is printed as written, being on the do-not-normalize list, and 傅 likewise — the corpus prints both 傅 and 敷 and they are not folded, so the transcription's 傅 stands.

Translation
Yellow ox dung, sun-dried, then calcined in the fire to an ash; take only the white part at the centre, wrap it in cotton and pat it on. — Jeongjeon 正傳 (Donguibogam · Soa)
Clinical commentary 臨床
One drug, prepared in three steps that matter: ox dung dried in the sun, burnt in the fire until it is ash, and then only the white part at the middle of the ash taken, wrapped in cotton and patted onto skin that has broken down in sheets and will not dry. 1.85.12 斑爛 is the gravest section of the chapter's complications — the pox failing to crust and the flesh going to rot — and extensive loss of skin means loss of the barrier: fluid and plasma protein leak out of the raw surface, the child cannot hold temperature, and infection follows into a wound the size of the body. The Bogam records the same picture in the Strange Diseases chapter's 4.1.22 渾身生燎疱, where it writes 不可治, and that judgement was right; before intravenous fluid, temperature control and modern wound care this could not be survived.
As a dusting powder, calcined ash would have been drying, and the selection of the white centre is not arbitrary — it is the part burnt most completely through, where the organic matter is gone and what is left is mineral. That instruction is the one defensible thing here, and a worker who followed it faithfully was reaching for the only part of the material that fire had made relatively safe.
**It was not safe enough, and the patient is a child.** Fully burnt ash is also strongly alkaline — potassium carbonate and lime — and alkali on denuded dermis is caustic and agonising, which is injury added to a surface that has none to spare. More seriously, dung is the textbook reservoir of *Clostridium tetani* and *Clostridium perfringens*, and clostridial spores survive heat that kills the vegetative organism; any part of the ash not burnt white carries them, and the instruction to pat the powder onto raw weeping skin is the exact mechanism by which tetanus enters a wound. **There was no tetanus immunisation, and the leaf gives no dose scaled to age or weight. This must not be prepared.** — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
