Abstract
Korean folk medicine 'NuRiJangNaMu' has been used mainly to cure neuralgia, arthritis, cough and abdominal lump. With regard to the botanical origin of NuRiJangNaMu, it has been considered to be Clerodendron species of Verbenaceae, but there was no pharmacognostical confirmation on it. To clarify the botanical origin of 'NuRiJangNaMu', the anatomical characteristics of the branches of Clerodendron species growing wild in Korea, Clerodendron trichotomum and Clerodendron trichotomum var. ferrugineum were studied. As a result, it was clarified that 'NuRiJangNaMu' was the branches of Clerodendron trichotomum.
