Clinical commentary 臨床

The name is the recipe: Pyeongwi-san and Ijin-tang laid over one another, with black atractylodes and pinellia promoted to equal chiefs at 2 don and the shared magnolia bark, tangerine peel and poria set at an even 1 don 2 fun 5 ri. Nothing is added; the formula is purely the two bases. The chapter puts it first among its food-malaria formulas and then tells you how to build on it — add unripe bitter orange, white atractylodes, hawthorn, medicated leaven and green tangerine peel — before offering Cheongpi-eum and Socheongpi-tang as alternatives. The reasoning is visible in the drug choice: food malaria is named for eating gone wrong, so the formula dries the dampness and moves the stagnation rather than attacking the paroxysm. Red poria rather than white is the Immun's choice throughout this group, draining rather than supplementing, which fits a repletion pattern in a patient who is still eating. — Eui Young (Justin) Chung, L.Ac., Dipl.
