Grey Oyster. Medicinal properties & health benefits.

Updated: Feb 16, 2020

Oyster mushroom (Pleurotus ostreatus) it’s a very popular mushroom around the world.

Very tasty and full of nutrition. High in proteins and all essential amino acids.

  • Important source of vitamin B complex:

B1 (thiamin), B2 (riboflavin), B5 (niacin), B6 (pyridoxine), B7 (biotin) or B12 (cobalamin).

B vitamins help the body to extract energy from fats, carbohydrates and proteins and are responsible for the function of neural cells and muscles. Especially beneficial for vegans and vegetarians and those suffering from high uric acid levels.

  • contains folic acid and vitamins C and D

Vitamin D (calciferol) promotes the formation of bone and prevents osteoporosis.

The folic acid is a significant factor in blood formation and promotes the growth of new cells, also in the bone marrow.

· Oyster mushroom lowers the blood homocysteine level.

This is very important, since a high level of folic acid and B vitamins in combination with low homocysteine reduces the risk of cardio-vascular diseases. Increased homocysteine levels entail higher risks for the development of vascular dementia and Alzheimer’s disease.

· Contains the ß-glucane (polysaccharide) pleuran. It has antioxidative properties and can inhibit the spread of metastases.

· contain a protein with antiviral properties.

Animal tests have demonstrated that it has a protective effect on organisms exposed to larger amounts of chemical substances. This is because the mushroom activates the body’s antioxidant enzymes (superoxide dismutase, catalase, glutathione system).

It is lowering the lipoprotein content, i.e. the cholesterol and triglyceride levels in blood and liver. Raising HDL at the same time.

Growth of prebiotic bacteria.

Studies done by the Prague Food Research Institute demonstrated that Pleurotus ostreatusto promotes the growth of probiotic bacteria in the intestinal flora. The generation of lactobacilli, enterococci and bifidobacteria is increased. This in turn positively affects the intestinal flora and the intestinal immune system. This is highly beneficial, e.g. after ingesting antibiotics.

Verified effects from research

The growth of lactobacilli, enterococci and bifidobacteria is promoted.
