Being salty flavor and cold nature, mirabilite acts as the assistant herb to soften hardness and moisten dryness for relieving constipation, which strengthens the purgative power of rhubarb. As the adjuvant herbs, magnolia bark and unripened bitter orange activate qi and dissolve accumulation for fullness and stuffiness, which help rhubarb and mirabilite in clearing.

This formula can be applied to acute simple intestinal obstruction, adhesive intestinal obstruction, ascaris intestinal obstruction, ascariasis of biliary tract, acute pancreatitis, acute appendicitis, and the beginning of acute bacterial dysentery pertaining to the excessive syndrome of Yangming fu-viscera.
