The invention discloses a rhizoma polygonati and fructus lycii enzyme. The rhizoma polygonati and fructus lycii enzyme is prepared from the following raw materials in parts by weight: 30 to 40 parts of rhizoma polygonati, 10 to 20 parts of fructus lycii, 10 to 15 parts of radix puerariae, 3 to 8 parts of grape fruit, 3 to 8 parts of cherry fruit, 5 to 10 parts of long-shaped rice, 4 to 10 parts ofmaltose oligosaccharide, 2 to 5 parts of poly-sugar alcohol, 1 to 5 parts of flavoring agent, 1 to 2 parts of vitamin C, 1 to 2 parts of vitamin E, 1 to 3 parts of soybean small molecule peptide, and2 to 6 parts of dietary fiber. The rhizoma polygonati and fructus lycii enzyme has the advantages that the dietary therapy functions of the rhizoma polygonati, the fructus lycii, the radix puerariae,the grape fruit, the cherry fruit, the long-shaped rice and the like are integrated, so that the nutritional components are more enough and balanced, and the purposes of reaching safety and sanitation in use, enhancing activity of the enzyme, meeting body requirements of people on enzyme, meeting body requirement on adsorbing of enzyme, promoting body health of people, and improving life qualityare realized; after the rhizoma polygonati and fructus lycii enzyme is eaten for a period of time, the effects of nourishing Yin and moistening lung, tonifying spleen and invigorating Qi, reducing blood glucose, nourishing liver and kidney, replenishing vital essence and improving eyesight, producing body fluid and promoting digestion, relieving fatigue, tonifying blood and invigorating Qi, dispelling wind and removing dampness, freeing Bi and relieving pain, beautifying face, and delaying aging are realized.
