In China, the underground part of genus Curcuma is divided into rhizome and tuber. They are named differently. The rhizome of C.phaeocaulis Val. is called Pengezhu (Ezhu, Wenzhu) and its tuber is called Lusiyujin. The rhizome of C.kwangsiensis S. G. Lee et C. F. Liang is called the following: the whole rhizome is called Wenezhu, the one which is cut longitudinally is called Pianjianghuang and the tuber is called Wenyujin. Their respective production areas are Sichuan Prov., Guangxi Prov. Zhuangzu Autonomous Region and Zhejiang Prov. The Pharmacopoeia of the People's Republic of China lists these three rhizoma as Ehzu. In Japan, They are cultivated in Kagoshima, Okinawa and other prefectures. Most of them are used as an ingredient for domestic medicine. The nomenclature is C. zedoaria Roscoe according to The Japanese Pharmacopoeia. Nomenclatures of Ehzu are complicated. In China, C. zedoaria Roscoe, C. caesia Roxburgh and C. aeruginosa Roxburgh have been applied as nomenclatures of Ehzu. But they were renamed as C. phaeocaulis Val. in 1989, since it became clear that they were not appropriately named in terms of the color of the rhizome and the flower bud. In Japan, Chinese ehzu is commonly used as a crude drug. Therefore, the quality depends on the original plant.
