By consulting the ancient and modern literature, the name, origin, quality evaluation, harvesting and processing methods of Curculiginis Rhizoma(CR) were systematically combed and verified, in order to provide a basis for the development and utilization of famous classical formulas containing CR. The results of herbal textual research showed that the name Xianmao was first recorded in Leigong Paozhilun, the name of CR was used in all dynasties and this name came from its efficacy and morphological characteristics, the mainstream source for CR of the past dynasties was the rhizome of Curculigo orchioides or C. capitulata, since modern times, C. orchioides has been the main source of commodities. In ancient times, most of the places of origin of the description were the western regions and southwest China, while in modern times, Sichuan and Guizhou were regarded as genuine places. Since modern times, its quality has been summarized as the best with thick roots, firm texture and black-brown surface, the harvesting and processing methods recorded in the past dynasties are mainly sun drying after harvest in the second, eighth and ninth months of the lunar calendar, and most of them are harvested in autumn and winter in modern times. In ancient times, there were many processing methods of CR, mainly in processing with rice swill, while in modern times, stir-frying with wine was the main processing method. The nature, taste, meridian tropism, functions and indications of CR are basically consistent from ancient to modern times, the taboos for taking are to avoid iron, cow's milk, and beef. Although there are some differences in the understanding of the toxicity of CR in the past dynasties, most of the materia medica are clear that it has a certain toxicity. Based on the research conclusion, it is suggested that the rhizome of C. orchioides of Lycoris family should be used as its source in the famous classical formulas, and the corresponding processing method should be selected according to the processing requirements in the formulas, while the raw products is recommended to be selected as medicine if the processing requirement is not specified.
