The processing of Mongolian medicine,which is called " mort harl" in Mongolian language,refers to a traditional processing technology to " tame" some toxic,aggressive,ineffective or inconvenient Mongolian medicines,so as to make it " compliant" to clinical needs. It is the summary of long-term experience in drug preparation by Mongolian medicine experts,one of the bridges for the dialectical unity of Mongolian medicine,the essential content in evaluation of the clinical efficacy of Mongolian medicine and the study of Mongolian medicine modernization,and also the important soft power carrier of " intangible cultural heritage" and " grassland culture" in Inner Mongolia autonomous region. In this study,the processing history,purpose,crafts,mechanism,processing standards and quality standards of Mongolian medicine were explained,and some suggestions were proposed for the problems of the Mongolian medicine processing and development: focus on the basic theory of Mongolian medicine and the clinical experience of Mongolian medicine in the development of traditional Mongolian medicine processing; strengthen the literature research on the processing method of Mongolian medicine; establish comprehensive and systematic Mongolian medicine concocts standards and quality standards; enhance the research and development of special processing equipment and process quality control instruments for Mongolian medicine; and strengthen the training of professional technicians,the protection of copyright in Mongolian medicine processing,and scientific research on Mongolian medicine processing. In the inheritance of the tradition,the latest achievements of modern scientific development can be also absorbed to provide reference for the further development of traditional Mongolian medicine processing technology.
