樗根白皮 Gadyungnamo Bulhwit Geopjil (가듁나모 불휫 겁질)
Jeogeunbaekpi is the inner bark from the root of the tree of heaven, Ailanthus. The tree grows freely on city waste ground and is not the Chinese toon whose spring shoots are eaten as a vegetable, though the names sit close. Donguibogam likewise separates cheo from chun, and notes the eye-like leaf scars that gave it the name homoksu.
