OBJECTIVE To establish the processing method of Cistanche Herba decoction pieces. METHODS Orthogonal test of 4 factors and 3 levels was used to optimize the main influencial factors of processing Cistanches Herba decoction pieces， including softening method， drying method and temperature， and thickness of the pieces. RESULTS The optimized process was to soft the crude drugs of Cistanches Herba by vapor for 2 h， cut them into pieces with 6 mm thickness， then heat them at 70 ℃ in an oven. CONCLUSION This processing method is stable and reproducible， which is feasible for the industrial production.
