Abstract
'JaGuiNaMu' is one of the Korean crude drugs used mainly to cure neuralgia, bone fracture, jaundice, and headache. With regard to the botanical origin of 'JaGuiNaMu', it has been considered to be Albizzia species of Leguminosae, but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'JaGuiNaMu', the anatomical characteristics of the branch of Albizzia species growing wild in Korea, A. julibrissin and A. coreana were studied. As a result, it was clarified that 'JaGuiNaMu' was the branch of Albizzia julibrissin.
