Abstract
'BaegDuOng(白頭翁)' is one of the Chinese crude drugs used mainly as a pruritus, arthritis, cough and abdominal pain. The botanical origin of the crude drug has never been studied pharmacognostically. To clarify the botanical origin of 'BaegDuOng', the morphological and anatomical characteristics of Pulsatilla species growing in Korea, i.e. Pulsatilla koreana Nakai and P. cernua (Thunb.) Spreng. were studied. As a result, BaegDuOng from Korea was proved to be the root of Pulsatilla koreana.
