Abstract: This study was aimed to collate, summarize and analysis the origin processing and its quality evaluation of Gastrodia elata,which was in the calendar edition of the Pharmacopoeia of the People’s Republic of China and in the research progress of Chinese and foreign literature during the past decade. Since the 1985 edition of the Chinese Pharmacopoeia, it had been recorded that the origin processing of Gastrodia elata was "The fresh Gastrodia elata was steamed through, opened wide, dried in the low temperature",which has been used until now. And its quality evaluation indicators gradually were evolved from the appearance characteristics to the internal indicators. This paper was summarized into five aspects: the purification process, steaming or boiling process, drying process, the integration of processing and processing of origin, and the application of new equipment and technologies. It was analysised the quality evaluation indexes of its appearance characteristics, internal indexes and pharmacodynamics in this paper. Based on the summary with the origin processing of Gastrodia elata in this study, it is urgent to formulate a reasonable and feasible modern the origin processing and quality evaluation system to standardize the origin processing of Gastrodia elata and ensure the output and quality of medicinal materials.
