title: Study on the difference between Shennong's drug nature quoted by Wu Puu and by Shennong's drug in material medical in classified syndromes (Zheng).
abstract: Several questions were mentioned through the analysis and comparison of "Shennong's drug nature" (DN) as quoted by Wu Pu's Meteria Madica (WP) and Materia Medica of Classified Syndrome (Zheng) (ZL). These include: (1) The DN in ZL are incomplete, the "toxic nontoxic" terms were absent here; (2) There were different editions of ancient "Shennong's Canon of Materia Medica", carrying different numbers of drugs, including 365 kinds, 595, 441, 319 kinds respectively; (3) some of the drugs indicated as DN were, strangely, indicated as "drugs of supplemented Records" in ZL.
