Survey on Pinellia ternata (Thunb.) Breit.Resource in China

Pinellia ternata(Thunb.)Breit.is extensively distributed all over the country except for several provinces such as Inner Mongolia,Jilin, Heilongjiang,Xinjiang,Qinghai and Tibet.In recent years,contradictions among the increasing market demand,the decline in wild resource,and the far lagged cultivation technique are increasingly aggravated.Through literature review coupled with visiting survey,we perform a comprehensive and systematic research on the sprouting resources and production status of P.ternata.As a result,the wild P.ternata mainly focus on Sichuan, Hubei,Anhui,Yunnan,Guizhou and other provinces of China.Most parts of cultivated resources are found in Gansu,Shanxi,Shandong, Guizhou,Yunnan,etc.Limited by natural environment and local human economic,the reserve and yield of P.ternata resource have already declined sharply in China.Now,to protect and study P.ternata has become an urgent problem.To guide the rational use of drugs,researchers should confirm the producing areas of P.ternata resource and ensure the availability and safety of medicinal materials,based on the collection and screening of P.ternata resource.These could contribute to the collection,protection,production,development and utilization of P.ternata resource.
