Effects of Powder, Extracts, and Components of Ganoderma Lucidum in Treatment of Diabetes

Ganoderma lucidum is known in China and Japan as Ling-Zhi and Reishi. Due to medicinal properties and different nutritional compositions, ganoderma lucidum is currently used in food products. It contains essential fatty acids, essential amino acids, and a wide range of polysaccharides; all of which seem to be effective in lowering blood sugar level. This study aims to review the anti-diabetic and hypoglycemic effects of various powders, extracts, and components of ganoderma lucidum, by searching articles in Persian and English published from 2001 to 2020 in SID, MagIran, Scopus, PubMed, Web of Science and Google Scholar databases using the keywords: Active compounds, ganoderma lucidum, diabetes mellitus, hyperglycemia. The results showed that ganoderma lucidum uptake in most cases reduced fasting blood sugar, glycosylated hemoglobin, and insulin resistance in diabetic patients due to the its active compounds including the extracted polysaccharides, proteins and triterpenoids. Moreover, its antioxidant and antiinflammatory properties seems to reduce the complications of diabetes. In conclusion, the consumption of ganoderma lucidum in diabetic patients can be effective in controlling and preventing the disease, although more studies are needed on its effective dose, side effects and toxicity in human samples.
