Method for preparing bezoar soft capsules for clearing away heat and reducing fire as well as dispelling wind and relieving pain

The invention discloses a method for preparing bezoar soft capsules for clearing away heat and reducing fire as well as dispelling wind and relieving pain. Active ingredients of prescription medicinal materials are extracted by using a membrane filter pressing cyclic extraction and separation integrated technology in place of a decoction method, an impregnation method and a percolation method. Thus, a process flow can be simplified, the production period is greatly shortened, energy consumption is reduced, environmental protection and waste residue utilization are facilitated, the using amount of ethanol serving as an extraction solvent can be reduced, and the recovery rate of the active ingredients is greatly increased.
