Abstract
Crude drug 'InDong(忍冬)' has been used mainly to cure common cold, high fever and gonorrhea. With regard to the botanical origin of InDong, it has been considered to be Lonicera species of Caprifoliaceae, but there was no pharmacognostical conformation on it. To clarify the botanical origin of 'InDong', the anatomical characteristics of the branches of Lonicera species growing wild in Korea, Lonicera japonica and L. japonica forma. chinensis were studied. As a result, it was clarified that InDong was the branches of Lonicera japonica.
