The involved 174 Chinese drugs selected from the 294 literature are di-vided into 19 major groups and 39 minor groups. The top three herbs categories were tonifying medicinal, heat-clearing medicinal and blood-activating and stasis-resolving medicinal. And of which the leading five drugs that were mostly used are Poria cocos, Acorus gramineus, Gin-seng, Angelica sinensis and Radix Rehmanniae Praearata. The association analysis revealed that Radaix Rehmanniae Praeparata and Fructus were the most relevant among all the selected drugs. The cluster analysis demonstrated that there existed five main clustering groups and two Chinese herb groups consisting of special Chinese herbs which were the mostly common choice or selected by syndrome differentiation. Con-clusions Common rules of clinical drug selection of Chinese drugs for the improvement learning ability and memory are surnmarized, which might guide the treatment of memory disorder.
