title: [Research on formulation process of yisheng capsule].
abstract: OBJECTIVE
  To choose the best supplementary material and formulation process of Yisheng capsules.
  
  
  METHODS
  The angle of repose, hygroscopicity and critical relative humidity were used as the indices to choose the formulation process of Yisheng capsules.
  
  
  RESULTS
  The best technique conditions were as follows: the extract powder and microcrystalline cellulose were mixed in proportion of 2:1, the 95% alcohol was used as the wetting agent.
  
  
  CONCLUSIONS
  The formulation process is rational and practicable.
