1. Immunomodulatory function
The immunomodulatory effect of the human body is the common effect of most active polysaccharides, and it is the basis for them to exert other physiological and pharmacological effects. Modern pharmacological research analysis shows that the viscous substance in the stem of Dendrobium is mainly water-soluble polysaccharide, which accounts for more than 25% of its dry weight. Factors have obvious effects. Under experimental conditions, they can also eliminate the side effects of the immunosuppressant cyclophosphamide. Clinical experiments have also proved that Dendrobium Candidum Polysaccharides has a very significant effect on regulating the body’s immunity.
2. Lower blood sugar
Diabetes, known as “Xiaoke” in traditional Chinese medicine, is a metabolic disease caused by insufficient secretion of the pancreas. Long-term use of western medicine to lower blood sugar and insulin injections have side effects. Studies have proved that Dendrobium Candidum Polysaccharides can significantly reduce the blood sugar level of the body, can promote insulin secretion and inhibit glucagon secretion. Different from oral hypoglycemic drugs such as sulfonylureas, Dendrobium Candidum Polysaccharides has no lowering effect on normoglycemia, does not increase serum insulin levels, and has a repairing effect on islet cells; meanwhile, Dendrobium polysaccharides also have extrapancreatic hypoglycemic effect, through Inhibit the decomposition of hepatic glycogen caused by adrenaline and promote the synthesis of hepatic glycogen, so as to reduce the source of blood sugar, increase the outlet of blood sugar, and achieve the purpose of reducing blood sugar level.
3. Anti-oxidation and anti-aging
The research found that many active Dendrobium Candidum Polysaccharides have the activities of scavenging free radicals, increasing the activity of antioxidant enzymes and inhibiting lipid peroxidation, which can protect biofilm and delay aging. Dendrobium contains high activity of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), which has strong antioxidant capacity, and Dendrobium Candidum Polysaccharides has a relatively strong antioxidant capacity under alkaline conditions. Good antioxidant activity. Experiments have shown that Dendrobium can significantly increase the levels of superoxide dismutase (SOD) and serum hydroxyprolinase (HYP), significantly reduce lipid peroxides (LOP) and monoamine oxides (MAO), thereby playing a role Anti-aging effect.
Dendrobium is not only rich in polysaccharides, but also rich in a variety of alkaloids, amino acids and starch. Although the pharmacological effects of these ingredients are interrelated, there are certain differences. For example, the main effects of alkaloids are “anti-tumor, cardiovascular disease, inhibition of gastrointestinal diseases, pain relief and fever reduction”; Aging and other aspects; and the polysaccharides in Dendrobium, its pharmacological effects are mainly manifested in the aspects of “improving immunity, lowering blood sugar and anti-aging”. Dendrobium has a wide range of functions. Therefore, “Shen Nong’s Materia Medica” lists Dendrobium as a holy medicine with the effect of “lightening body and prolonging life”. Dendrobium Candidum Polysaccharides are easily absorbed by the body, nourish the whole body, let the body’s organs operate freely, and the skin is moisturized. The qi and blood are unobstructed, and after a period of time, it can make people get rid of the troubles of diseases and rejuvenate their youthful brilliance.
