Cassia Semen (JP IX) are imported from China, Vietnam and many other countries. Accordingly, the morphological characteristics of the crude drug vary. The authors attempted to classify Cassiae Semen using four morphological characteristics and calculating Maharanobis' distances. The determinations of the four elements needed for the calculation, i.e., the height, width, length and weight of 200 seeds from 20 groups of Cassia obtusifolia, C. Tora, C. torosa and C. nomame and the crude drugs of Cassiae Semen, led to the possible classification of the Cassiae Semen into 4 groups. A: large grain (Ootsubu-de) from north Korea and Japan. B: large grain from China. C: Japanese intermediate grain type from Japan. D: small grain (Kotsubu-de) from China and Vietnam. C. tora is included in group D; the small grain variety of the crude drugs originate from C. tora. C. torosa and C. nomame are independent groups.
