Generally refers to a class of metabolites produced by the substrates and mycelium of various fungi. Currently, there are about thousands of species of fungi worldwide. Among them there are not only many delicious fungi with practical value, but also many fungi with health care functions. Of course, there are also many poisonous mushrooms with toxicity and so on

Compound polysaccharide is the result of more than twenty years of research at the Southern Medical University (formerly the First Military Medical University). With high-tech means, strict quality management, from Ganoderma lucidum, Poria, silver fungus and shiitake mushrooms and other natural fungal plants extracted from the fungal polysaccharides, after countless repeated experiments, screened out the most scientific and effective combination of polysaccharides with the proportion of complex together, forming a composite polysaccharides, has a strong biological activity. Composite polysaccharide is the crystallization of several active polysaccharides modified by biochemical technology and optimized effectively. The complementarity between its bioactive polysaccharides is incomparable to any one active polysaccharide. Complex polysaccharide has many aspects of biological activity, is the world's best immunomodulator with high quality and without any toxic side effects, leading at home and abroad. Complex polysaccharides can effectively and comprehensively enhance the body's immunity, but also an important part of the structure of cells and organelles, is the body's cells or organs to maintain the normal function of the main indispensable ingredients.
