葉 Oyat Ip (오얏 잎)
Plum leaf refers to the leaf of the plum tree. In the original text it is called oyat (오얏), an archaic Korean name for the plum. In Dongui Bogam, following the entry on the plum kernel (ihaegin, the seed kernel used as a medicine in its own right), the book lists the inner bark of the root, the leaves, and the fruit in sequence — this entry covers the leaves. The leaf is an elongated oval with a pointed tip and finely toothed edges. The plum belongs to the same family as the Japanese apricot and the cherry, and in spring its branches are lined with dense clusters of white blossoms.
