After numerous repeated experiments, the most scientific and effective combination and ratio of polysaccharides were screened out to form composite polysaccharides, and their biological activities were highly complementary. After repeated experiments and clinical screening, each active polysaccharide was screened out with high activity and complementary functions, achieving a more comprehensive and efficient effect. In the mutual proportion of various active polysaccharides, the best proportion combination with synergistic effect was found, which made the immune surface activated by compound polysaccharides more and the effect was more obvious.
