The historical evolution of the processing methods of Atractylodis Rhizoma are based on the theories

such as syndrome differentiation principles of treatment and three categories of etiological factors system

which can meet the need of traditional Chinese medicine(TCM) clinic requirement.There are different processing methods including rice-water-frying

bran-frying
