Edible fungus polysaccharide is a special biologically active substance, a biological response enhancer and regulator, which can enhance humoral immunity and cellular immunity. The antiviral mechanism of edible fungus polysaccharide may be that it improves the immunity of infected cells, enhances the stability of cell membranes, inhibits cell pathology, and promotes cell repair and other functions. At the same time, edible fungus polysaccharides also have antiretroviral activity. Therefore, edible fungus polysaccharide is a kind of anti-influenza health food to be developed.
They are indispensable substances in the metabolism of life. Polysaccharide is a polymer composed of more than 7 single molecules connected in the same way as unwillingness.
It has many functions such as anti-virus, anti-cancer, lowering blood sugar and improving immunity.
Fungus polysaccharides have significant effects in the prevention and treatment of liver diseases. For example, lentinan(Shitake polysaccharides) has obvious effects on the treatment of chronic hepatitis and lowering enzymes, and the clinical cure rate is as high as 70%. It can also reduce the side effects of chemotherapy.
Poria cocos polysaccharides are mostly used in the treatment of hepatitis by injection, and the effect is remarkable. In the case control of the patients using Volumene polysaccharide, 96% of patients with normal liver function are better than other hepatitis B drugs.
Cordyceps polysaccharide can improve the cellular immune function of patients with chronic hepatitis B, thereby effectively improving liver energy.
Hericium erinaceus polysaccharide has a good effect on the treatment of chronic gastritis.
