Processing Chinese medicinal materials while they are fresh has advantages over traditional processing，such as improving production efficiency，reducing production costs，minimizing the loss of active ingredients and facilitating storage and transportation. Origin processing is a key technical link in the formation of the quality of Chinese medicinal materials，and different origin processing methods have a certain impact on the appearance and internal quality of Chinese medicinal materials. Drying is one of the key processes in the processing of traditional Chinese medicine and decoction pieces. The drying methods and process parameters in the production area have a significant impact on the quality of traditional Chinese medicine decoction pieces，and there are differences in drying methods and temperatures among different medicinal parts. This article classified Chinese medicinal materials according to their medicinal parts. Roots and rhizomes are generally dried at a low temperature around 60℃，while leaves，whole grass and flowers are not suitable for high-temperature drying as traditional processing methods such as shade drying or low-temperature drying are used. Some skin type Chinese medicinal materials are rich in volatile oil，and the main drying methods are low-temperature drying and freeze-drying. Seed and fruit type Chinese medicinal materials are generally dried at low temperature. Through sorting out and summarized the processing technology of origin processing of traditional Chinese medicine，the influence of drying on the chemical components of traditional Chinese medicine in the“integration”process was analyzed. It is urgent to seek scientific and reasonable origin processing methods to provide reference for future research on origin processing processing directions.
