title: [Surveys on resources and varieties on Chinese markets of crude drug Xixin].
abstract: Many species of the genus Asarum plants are used as Chinese traditional or folk medicines, in Chinese which are known as "Xixin" (Asari Radix et Rhizoma) , "Bei-Xixin" , "Hua-Xixin" and "Nan-Xixin" , etc. In order to get a clear picture of resources distribution and varieties on Chinese markets of the crude drug Xixin and provide scientific basis for their resource conservation and sustainable use, during recent years we conducted field investigations and market researches many times. The results showed that the resources of both official Xixins and non-official Xixins were decreased because of the ecological environment damage and over-digging, especially species whose population size was small. Bei-Xixin derived from A. heterotropoides var. mandshuricum was the most species on the Chinese markets except for a few areas of China. Hua-Xixin derived from A. sieboldii and non-official Xixins were mainly used in their producing areas. Cultivation of Hua-Xixin should be greatly developed, and wild resources of non-official species must be preserved strictly.
