Abstract
Korean folk medicine 'BoRiSuNaMu' has been used mainly to cure apepsia and cough. With regard to the botanical origin of BoRiSuNaMu, it has been considered to be Elaeagnus species of Elaeagnaceae, but there was no pharmacognostical conformation on it. To clarify the botanical origin of 'BoRiSuNaMu', the anatomical characteristics of the branches of Elaeagnus species growing wild in Korea, Elaeagnus glabra, E. macrophylla, E. multiflora, E. submacrophylla, E. umbellata and E. umbellata var. coreana were studied. As a result, it was clarified that 'BoRiSuNaMu' was the branches of Elaeagnus umbellata.
