title: [Pharmacognostical study of tall monkshood root].
abstract: OBJECTIVE
  To provide the scientific basis for gruffs identification and utilization of tall monkshood root.
  
  
  METHODS
  We studied tall monkshood root through the macroscopic, microscopical and Physicochemical identification.
  
  
  RESULTS
  In the cross section of tall monkshood root, there were cork cortex cells, a cricoid range hetero-vascular bundle, radial-cell including radial little brown cell, a great deal of starch grain, cortex organize fragment was brown, cell squareness and polygon.
  
  
  CONCLUSIONS
  These character can provide scientific basis for its quality standard and development.
