Artemisia argyi is the leaves of compositae plants of A. argyi Lévl. et Vant.， which is a traditional Chinese medicine commonly used in China. The analysis was carried out by consulting traditional medical classics， modern standard norms and literature， and using Cytoscape software to sort out and visualize the evolution of the processing and the efficacy of processed products. The processing of A. argyi was first made in the Han dynasty and was popular in the Song and Ming dynasties. There were many processing methods in ancient times， including net processing， cutting， frying， processing with auxiliary material （vinegar， wine， salt， charcoal， rice water， sulfur， medicinal juice， jujube mud processing） and other processing methods （baking， winching， making herbs into wool）. Modern common processing methods included purification， vinegar processing， charcoal processing and making herbs into wool， which are relatively simple compared with ancient processing methods. There were obvious differences in the efficacy and application of raw and processed products of A. argyi. Although the processing effects of A. argyi in ancient and modern times were mainly to reduce toxic side effects and enhance the effects of warming meridians and hemostasis， only the purified A. argyi， vinegar-processed A. argyi and vinegar-processed A. argyi charcoal could be seen in the present studies， other processed products had not been inherited and studied， and the processing mechanism was still unclear. It is suggested that in the later exploration and research， researchers can establish a multi-dimensional standard research system based on the characteristics of the medicinal plant A. argyi and the processing characteristics of A. argyi decoction pieces in order to systematically explore the transformation rules before and after processing， and clearly explain the scientific connotation.
