Abstract
Members of the genus Rabdosia (Labiatae) grow naturally in eastern Asia, but only species found in Japan and China heve been investigated chemically. In Japan, the leaves of Rabdosia japonica and R. trichocarpa are used as a common household medicine for gastrointestinal disorders. The drug is called “enmei-so”, which means “grass effective for prolongation of human life”. In China, some Rabdosia species are used as antitumor and antiphlogistic agents. Species now included in the genus were formerly referred to Plectranthus and Isodon, but since 1972 the genus name Rabdosia has been adopted in accordance with a recommendation by Hara (1).
