The Chinese crude drug so called "Gehua" has been used for the treatment of crapulence as a folk medicine in China, Formosa, Korea and Japan. The original plant of this was considered to be the flower of Pueraria spp. in Leguminosae. Four kinds of "Gehua" on Chinese, Formosan, Korean and Japanese markets, were taken as the materials. To clarify their origins, we studied external and internal morphological characters of Pueraria spp. collected in Hong Kong, Formosa and Japan. The main characters of them are shown in TABLE I. Consequently, the origins of "Gehua" on Chinese market are proved to be Pueraria chinensis OHWI, the Formosan ones are P. montana MERRIL., and Korean and Japanese ones are P. lobata OHWI. Chinese Pueraria flower which contains kakkatin (=6, 4'-dihydroxy-7-methoxy-isoflavone) is identified as the flower of Pueraria chinensis.
