Pharmacognostical Studies on the Folk medicine 'Koaeng I Bab'

Korean folk medicine 'Koaeng I Bab' has been used to cure hemorrhoid, boil and dermatopathy and as an antidote. The botanical origin of the crude drug has not been studied pharmacognostically. To clarify the botanical origin of 'Koaeng I Bab', the morphological and anatomical characteristics of the leaves of Oxalis species growing in Korea, i.e. O. acetosella, O. acetosella var. purpurascens, O. corniculata, O. obtriangulata were studied. As the result, the botanical origin of 'Koaeng I Bab' has been proved to be O. corniculata and O. acetosella var. purpurascens.
