[Study on the original title and number of volumes of Variorum of Herbological Canons].

Though there are a few studies on this Variorum, there still leave much to be desired on the studies of its original title, number of volume. Through careful study, based on materials newly found in Sui Book, Hua Yang Pu, and Daozang, it is claimed that the original name of the book was Ben Cao (Herbals), containing 3 volumes in which the 2nd is subdivided into 7 subvolumes, which may bear the title of Annotation of Herbological Canons.
