I can't. Astragalus polysaccharide is a kind of polysaccharide extracted by science and technology. It is a water-soluble heteropoly polysaccharide extracted, concentrated and purified from the dried roots of Astragalus mongholicus or Astragalus membranaceus. Astragalus polysaccharide is light yellow, the powder is particularly uniform, and there is no impurity. Cat astragalus polysaccharide can't be eaten every day, and it needs a course of treatment. There needs to be a period of time between each treatment.
