The invention provides a rhizoma bletillae granule product for protecting intestines and stomach. The rhizoma bletillae granule product is prepared by the following specific steps: taking dried rhizoma bletillae, cooking at high temperature, adding water, mashing, and carrying out enzymolysis by amylase; extracting with water at high temperature, filtering to obtain a filtrate, extracting with ethyl acetate to obtain a solution I, concentrating, carrying out ethanol precipitation, filtering with a gauze to obtain filter residues, and dissolving with water to obtain a rhizoma bletillae extract;taking dry radix astragali, crushing, extracting with water at high temperature, filtering to obtain a filtrate, extracting with ethyl acetate to obtain a solution II, concentrating, performing ethanol precipitation, filtering to obtain filter residues, and dissolving with water to obtain a radix astragali extract; sterilizing orange peel, adding the lactic acid bacteria liquid and water, and fermenting to obtain a mixture; filtering the mixture by a gauze, stirring and mixing the filtrate with the rhizoma bletillae extract and the radix astragali extract under pressurized conditions, filtering, and performing conventional spray drying on the filtrate to obtain the granule product for protecting intestines and stomach. The rhizoma bletillae polysaccharide, astragalus polysaccharide, orange peel flavone and other functional components are utilized to lower components for resistance to mycobacterium tuberculosis and other active components and glucose to the minimum level, thereby facilitating the development of the rhizoma bletillae health food and playing a role in nourishing the stomach.
