"Toyaku" has been a common folk medicine used as a bitter stomachic in Japan. In Japanese Pharmacopoeia VII, "Toyaku" originated from Swertia japonica MAKINO. Recently three kinds of "Toyaku", one of them from Korea and the others from Formosa, have been imported as a substitute for that from Japan. From the comparative histological and taxonomical investigations on "Toyaku" from Korea and Formosa, it was proved that these three "Toyaku" from Korea, Formosa (A), and Formosa (B) were identified with Swertia pseudochinensis HARA, Swertia randaiensis HAYATA, and Swertia chirata HAM. respectively. But S. chirata HAM. has no distribution in Formosa. So the marketed material from Formosa (B) was supposed to be the material from India which was once exported to Formosa and then reexported to Japan as the material from Formosa. The observations were mainly made in conformity with the number of lobes of calyx and corolla, nature of veins on calyx, nature of the nectary on corolla, hair growing on the periphery of the nectary and nature of cuticle accumulated on the epidermis of the leaves and stems. The details are as Table 1.
