RemarksHenzui (扁豆衣, Jap. name) is the seed coat of Fujimame (Dolichos lablab L.) and used like Biandou (扁豆). Henzuka (扁豆花, Jap. name) is the flower of Fujimame and used for diarrhea, concentrated blood, leukorrhea etc. The genus Lablab consists of one species, Lablab purpureus. Though it was classified into genus Dolichos in the past, now it is divided into another genus according to the the shape of style. Both the Japanese and Chinese Pharmacopoeia adopt the former nomenclature Dolichos lablab.
