Rhizoma smilacis glabrae chewable tablet with anti-oxidation effect and preparation method thereof

The invention discloses a rhizoma smilacis glabrae chewable tablet, an active substance in the rhizoma smilacis glabrae chewable tablet is a rhizoma smilacis glabrae alcohol extract, and preferably, the active substance also comprises a licorice extract. The preparation method of the rhizoma smilacis glabrae chewable tablet obtained by optimization comprises the following steps: weighing 0.2 g of rhizoma smilacis glabrae alcohol extract, mixing with 0.025-0.1 g of licorice extract, adding 0.24 g of pregelatinized starch, equivalently and uniformly mixing for multiple times, adding 0.06 g of microcrystalline cellulose, uniformly mixing, adding a proper amount of 70% ethanol to prepare a soft material, carrying out wet granulation by using a 18-mesh sieve, drying at 50 DEG C for 20 minutes, carrying out size stabilization by using a 14-mesh sieve to prepare dry particles, adding 0.03 g of xylitol and 0.045 g of crystalline maltitol, and carrying out granulation by using a 20-mesh sieve to prepare the rhizoma sm
