Botanical Description
Phellodendron chinense, and the closely related P. amurense, are deciduous trees in the Rutaceae family, native to East Asia, particularly central and northern China, Korea, and the Amur River region. They typically reach 10-25 meters tall, with a broad spreading crown and thick, deeply furrowed, cork-like grey bark; the inner bark is conspicuously bright yellow and intensely bitter. The opposite, pinnately compound leaves bear 5-13 ovate to lanceolate, acuminate leaflets, each 5-10 cm long, with finely serrate margins and an unpleasant odor when crushed. The trees are dioecious; small yellow-green flowers are borne in terminal panicles in early summer, followed on female trees by clusters of black, pea-sized drupes. In TCM, the inner bark (Huang Bo) is harvested from mature trees and used as a bitter, cold herb to clear damp-heat, drain fire, and detoxify.
