The traditional Chinese drug "Xiangru" had always been regarded as a herb of Elshotzia splendens Nakai ex F. Maekawa and Mosla, chinensis Maxim belonging to the family Labiatae for a long time. Since 1983, samples of "Xiangru" have been collected from 22 different habitats and drug markets, including its main habitat in Jiangxi province. However, after being identified, most of them were found to belong to Mosla chinensis Maxim, and two belonging to Origanum vulgare Linn, but none belonging to Elshotzia splendens Nakai ex F. Maekawa. In order to clarify facts, the wild-growing Elshotzia splendens Nakai ex F. Maekawa was collected and its original plant, description, microscopic characters, "TLC and UV of its essential oil and antibiotic activity, were compared with those of Mosla chtinensis and Origanum vulgare. It was found that in many aspects, there were contrasting differences among them. Results indicate that Mshoizia splendens ex F. Maekawa is not included in the origin of traditional Chinese drug "Xiangru", and reports of "Xiangru" in literatures published should be corrected.
