The plant considered to be the source of the crude drug, Wujiapi, was examined morphologically. Many plants are known to be the source plant of this drug and they are in both Asclepiadacea and Araliacea families. Morphological examinations were made with special stress on the characteristics of these two families and the plant, which was being examined for constituent principles, was found to have the characteristics of Periploca sepium BUNGE of Asclepiadacea family, which is found in Chinese literature (as the source of this crude drug).
