RemarksThere are two types in "Zhimu (知母)", "Maozhimu" and "Guangzhimu". "Guangzhimu", in which yellowish brown fine roots of the surface have been removed, is appreciated as high quality in China, but it is not used in Japan. The rhizome of Aspidistra genus of family Liliaceae is a substitute for above in Zhuangzu Autonomous Region of Guangxi Province ("Maozhimu") and Taiwan ("Guangzhimu").
