Modified smectite and method for producing the same and its application

Disclosed is an inorganic medicine, particularly modified montmorillonite, method for preparing the same and use thereof. The said modified montmorillonite means that dioctahedron of natural montmorillonite is not destroyed and basic chemical composition for the same is not changed, and the microstructure stacked from dioctahedron layer is changed to decrease the thickness of stacking layer and to expose and increase the end face charge and the interlayer charge of montmorillonite, thereby resulting in its lower degree of C axis order. The present medical use of montmorillonite is thus significantly strengthened, particularly the reversal treatment effect on chronic atrophic gastritis. Also disclosed are a medicine composition containing modified montmorillonite and the reversal treatment effect of natural montmorillonite on chronic atrophic gastritis.
