'Whang Baig(黃柏)' is one of the crude drugs used mainly as a removing dampness, purging fire, detoxicating, and cleaning away heat of deficiency type. The botanical origin of the crude drug has never been studied pharmacognostically in Korea. To clarify the botanical origin of Whang Baig, the anatomical characteristics of Phellodendron amurense Rupr., Phellodendron insulare Nakai and Phellodendron molle Nakai were studied. As a result, it was clarified that Whang Baig from Korea was the bark of Phellodendron amurense and Phellodendron molle.
