葉 Gyullamu Ip (귤나무 잎)
Leaf (葉, Yeop)
Yeop is the leaf of the tangerine tree. In the Dongui Bogam, it appears in the Fruits section (果部) as one of the parts recorded under the tangerine entry, listed after the peel, the flesh, the white inner membrane, the seeds, and the green (unripe) peel.
The tangerine is an evergreen, so its leaves do not fall even in winter. The leaf stalk bears a small wing-like flange — a feature distinctive enough that a tree can be recognized as a citrus by its leaves alone.
In citrus orchards today, only the fruit is harvested; the leaves are not put to any separate use.
