Augmented Disperse Wind Powder

The preceding leaf with one drug added. Green tangerine peel, 2 don 5 fun, goes into 宣風散 and the method is unchanged; this is also one of the two formulas 百祥丸 names when it declares itself too drastic, so the chapter treats it as the safer of the purges for black sinking. What is worth reading closely is the rest of the leaf, which is a protocol rather than a prescription. The purge is expected to bring black stool first, then brown; then the child is given 四君子湯 with magnolia bark, costus and glutinous rice to settle the stomach after it; after a good while the stool turns yellow, and that is read as the end point, at which the sores begin to come out on their own; and only then is coriander wine sprayed on the skin to bring the eruption up. A sequence, with a stated marker for when to stop and a restorative built into it. **The marker is almost certainly being misread.** Black stool in a child with haemorrhagic smallpox is melaena — digested blood from the upper gut — and bleeding into the gut was one of the things the haemorrhagic form did; the chapter names the haemorrhagic turn separately at 1.85.15 失血. Here the black stool is taken as proof that the purge is working and the poison is coming out, and the brown and then yellow stool as proof that it has finished. A drastic cathartic given to a child who is bleeding internally will make the bleeding worse, and the sign the leaf is waiting for is the sign that it has. **依上法服之 carries the parent leaf’s dosing across with everything else, so this powder too is dosed by the child’s age** — 5 fun at two or three years, 1 don from four or five upward. The same judgement applies: the chapter is scaling, which is more than it usually does, but age is not weight, and a dose graded in two steps gives no margin to a child who has been purged until the stool ran black. **Contains 黑丑, black morning glory seed, a drastic purgative, given by mouth to a small child who may be dehydrated and bleeding into the gut. This must not be prepared or given.** — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
