The invention discloses a polysaccharide complex of cordyceps sinensis and snow lotuses for tonifying kidney and improving spermatogenesis. The polysaccharide complex of the cordyceps sinensis and snow lotuses for tonifying the kidney and improving the spermatogenesis comprises the following components in parts by weight: 45 to 55 parts of a cordyceps polysaccharide complex, 8 to 12 parts of oyster peptides, 8 to 12 of a rhizoma polygonatum extract, 6 to 10 parts of venison powder, 6 to 8 parts of snow lotuses, 4 to 8 parts of sea cucumber peptides, 8 to 10 parts of medlar, and the balance ofmedical or food health auxiliary materials. According to the invention, efficacies of the rhizoma polygonatum extract, oyster peptides, venison powder, snow lotuses and sea cucumber peptides are further enhanced through the particularity of the cordyceps polysaccharide complex; the cordyceps polysaccharide complex is in compatibility with the oyster peptides, medlar, rhizoma polygonatum, venison powder, snow lotuses and sea cucumber peptides to achieve the functions of nourishing yin, tonifying the kidney and improving the spermatogenesis, and in practice, the cordyceps polysaccharide complexcan effectively tonify the kidney, improve the spermatogenesis and enhance kidney functions of men and women to enhance the sexual abilities of men and women. In addition, the polysaccharide complex uses raw materials of homologous raw materials of medicines and food, and adopts the highest safety level, namely the food raw materials which can be used without limitation are in reasonable compatibility, so that the polysaccharide complex has both the efficacies and safety, and no side effects and dose limit.
