Note (47) — BOOK V.
James Greive translation
47. Oesypum is the oily part collected from sordid wool thus: the wool was washed in warm water, and all its sordes expressed, the fat swimmed a-top, with a froth, and upon throwing in some sea water, it subsided to the bottom, and when all the œsypum was obtained from it in this manner, it was purified by repeated affusions of water. When pure it has no sharp taste, but is in some degree astringent, and appears white. It has a heating quality, fills up ulcers, and is emollient. Dioscorid. lib. ii. cap. 272.
