Mica Paste

Unmo-go

雲母膏

This is the leaf 癰疽門 points at. Its entry there carries the indications and the pill method but no composition, referring it away with the interlinear note 方見雜方; this leaf supplies the composition and closes that composition-less cross-reference. 槐枝, sophora twig, and 合歡, albizia, have no identifiers in the herb list — the list holds 槐皮 and 槐實 for the one and 合歡皮 for the other, which are different drugs — and both are left out of the ingredients. 清 is printed 淸, 黄 as 黃, 桒 as 桑, 术 as 朮, 𥂁 as 鹽, 㷔 as 焰, 癕 as 癰 and 凣 as 凡 by the usual normalisations; 側栢葉 and 白歛 keep the transcription's forms. A collation note 桒 : 桑(First Edition) sits two leaves on, inside the 神異膏 leaf, but the character it annotates is 桒白皮 in this leaf; it is a pure glyph variant already covered.

Translation

Mica, saltpetre and licorice, 4 nyang each; sophora twig, willow twig, tangerine peel, mulberry root bark, arborvitae leaf and quicksilver, 2 nyang each; Sichuan pepper, angelica dahurica, myrrh, red peony, cassia bark, angelica sinensis, salt bloom, astragalus, dragon's blood, calamus, bletilla, chuanxiong, costus, ampelopsis, saposhnikovia, magnolia bark, musk, platycodon, bupleurum, pine resin, ginseng, scutellaria, atractylodes lancea, gentian, albizia, frankincense, aconite, poria and lesser galangal, 5 don each; red lead 14 nyang; clear oil two and a half geun. Set aside the mica, saltpetre, dragon's blood, myrrh, frankincense, musk, red lead and salt bloom; cut up the remaining drugs and steep them in the oil for seven days, then simmer over a gentle fire until the angelica dahurica and the aconite have browned, wring the oil out through cloth to remove the dregs, and boil it down again. Then add the eight drugs named above as fine powders, and stir without letting the hand rest, with a willow-wood paddle, until the paste sets — the test is that a drop in water forms a bead. Pour it into an earthenware vessel and flick quicksilver over the surface; each time it is used, scrape the quicksilver away. For every abscess and sinus abscess and sore-swelling, laid on outside and taken internally, the effect is divine. — Gukbang 局方 (Donguibogam · Japbang)

Clinical commentary 臨床

The longest of the plaster leaves and the one with the fullest instructions, because it is the only one of them meant to be used from both sides at once: the plaster on the skin over the swelling, and the same mass rolled into seed-sized pills and swallowed thirty at a time in warm wine. That internal clause is printed here as the leaf has it; it is the exception in a section of surface applications, not the pattern. The indication list is a list of abscesses by site, and the deep ones — 骨疽, 內疽, 肺癰, 腸癰 — are precisely the ones a surface dressing cannot reach, which is why swallowing it was proposed. 下膿血卽愈, cured once pus and blood have passed, shows what was expected of the pills: that they would make a deep collection discharge by a natural route. Mica is the name drug and is inert. Now that the composition is in hand, the formula can be read for what it is: thirty-eight drugs in a lead-set oil base, with the aromatics and the resins thrown in as fine powders at the end so the frying does not drive them off. The quicksilver is the strangest instruction in the chapter — it is not cooked into the mass at all but flicked over the surface of the set plaster and scraped off before each use, which reads as a keeping measure rather than a medicine. **Contains quicksilver (水銀), which is metallic mercury, red lead (黃丹), which is lead tetroxide, and aconite (附子), which is toxic. This must not be prepared.** The route that matters for an ointment is absorption through broken skin: an abscess or an open sore has lost the barrier that keeps metals out, and a lead- and mercury-bearing paste laid on it for days delivers both into the body. Lead and mercury are cumulative poisons with no safe dose, and this leaf also directs the mass to be swallowed. An abscess of bone, lung or abdomen is a surgical and antibiotic problem, and a plaster taken by mouth will not touch it. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
