Bio-Active polysaccharides, also called proteoglycans, are a family of complex carbohydrates that bind to proteins. Some plants produce them as an extremely effective defence mechanism against attack by viruses, bacteria, fungi, soil-borne parasites, cell mutations, toxic pollutants and environmentally free radicals. There are four unique polysaccharides found in Goji, and each one has a different effect on the immune system, cell growth and other bodily functions. That is why Goji has such far reaching benefits. It is like the Commander-in-Chief of the defence resources your body marshalls to prevent, combat and defeat every type of disease.
