吳茱萸 Osuyu(osuyunamu Yeolmae) (오수유(오수유나무 열매))

Osuyu is the unripe fruit of the evodia tree, a citrus-family shrub. The text says it resembles a peppercorn, pale yellow when young and deep purple when ripe, gathered on the ninth day of the ninth month and dried in shade. Marked 【唐】 as a Chinese import, it adds from Sokbang that in Korea the tree grew only around Gyeongju.

    HomiclubThe Sokbang citation is where the text steps beyond copying Chinese sources to record local circumstances. The evodia tree was originally brought in from China and grew in only a few places in Joseon, which is why the Donguibogam marks this material as a Tang (唐) import.
