The pancreas is the organ responsible for producing insulin for cells. Insulin is a protein that allows blood sugar to pass into the muscle. Therefore damage to the pancreas causes problems in the sugar management system of the body and can trigger obesity and diabetes.


Reishi consumption protects from damage in the pancreas occasioned by the toxic molecule named “alloxan”. This molecule is residually present in refined white flours: it is produced by the oxidation of the pigments called xanthophylls with chlorinated compounds that are used during bleaching (but don’t worry, because it is found in negligible quantities!).

Alloxan causes selective destruction of the beta cells of the pancreas, causing a loss of functioning of the pancreatic islets and therefore causing hyperglycemia (diabetes) and ketoacidosis in laboratory animals.

In this research, they study the influence of reishi on the protection of pancreatic islets, both in vitro and in animals (in vivo). Pure reishi polysaccharides were exposed for 12 h and 24 h to pancreatic cells and these molecules significantly reversed the loss of viability of the islets when affected by alloxan.

Animal tests: Reishi polysaccharides were given to mice for 10 days, prior to alloxan poisoning. The reishi consumers found their blood sugar reduced and their serum insulin increased, compared to those who did not consume reishi.

These results suggest that pure reishi protects the pancreas of animals from damage caused by alloxan, a molecule present in some foods. One of the mechanisms of action is the protection of the organ through reishi polysaccharides with high antioxidant power that prevents the oxidation induced by alloxan in the pancreatic islets.
Remember that reishi extracts in the market may not concentrate the polysaccharides that act to protect the pancreas. Only pure quality reishi, which was used in this research, surely contains the active molecules. Read the differences between pure reishi and reishi extracts here.
