COS is the positively charged dietary fiber, can form dense inclusions in the surface of cancer cells, to:

A, prevent food supply to the cancer cells, the division was reduced, restricting the cancer cell division;
Second, the reduction of cancer cell metabolism of acidic waste, improve around the tumor cells in the acidic environment from on the other hand, create a cancer cell is difficult to survive and splitting transfer environmental conditions.
Third, to reduce the cancer cells to surrounding the release of various enzymes (soluble lipase, protease, protease, etc.), decrease due to the catalysis of enzyme to surrounding healthy cells.
In addition, chitosan oligosaccharide can make pH value of body fluids alkaline, can activate the immune cells, enhance the ability to attack cancer cells; around the cancer cells were generally acid, chitosan oligosaccharide can around the tumor and acidic substances, accelerate the metabolism of free radicals and other toxic substances, to combined with chemotherapy, improve symptoms, relieve pain, prolong life role.
