Pleurotus ostreatus


It is the world’s most important edible mushroom, even ahead of the button mushroom: Pleurotus ostreatus, better known as the oyster mushroom, is, however, not only used as an ingredient but also as a health-promoting dietary supplement. It is rich in various vitamins and antioxidants, can strengthen the nervous system and protect the cells, as well as have a positive influence on the cholesterol metabolism. The oyster mushroom provides all of the amino acids that are important for humans, which are essential for the development of protein structures and take on key roles in the metabolism.

Applications tested in practice

• Protection against free radicals

The extract of Pleurotus ostreatus can reduce oxidative stress and contribute to protecting the body’s cells. It possesses a positively increasing effect on the enzyme catalase, which is responsible for converting hydrogen peroxide into oxygen and water, and thus frees the body from the oxidative substance.

• Reduction of blood lipid levels

The positive effect of this medicinal mushroom on the cholesterol metabolism, on triglycerides, LDL and phospholipids is above all attributed to the substance lovastatin. In contrast, there were no detrimental effects on other blood parameters, which often occur with other medications to regulate blood lipids.

• Support for weight loss

Pleurotus ostreatus can promote weight loss. This effect should not be underestimated, particularly in connection with blood lipid regulation, as obesity itself is a major risk factor for various illnesses such as diabetes and constrictions of the coronary arteries.

• Tumour-inhibiting effect

Pleurotus ostreatus can be used both therapeutically and preventatively with good success for tumours and, according to an American study, particularly for breast cancer and bowel cancer. The mushroom can significantly suppress the proliferation of mutated cells without any negative influence on the surrounding healthy cells.

Special features

With sufficient humidity, oyster mushrooms can grow easily by themselves from spawn on bales of straw. Good spawn can be purchased from specialised providers, who also provide instructions for cultivation. Fresh oyster mushrooms are a delicacy, but cannot replace a targeted dietary supplement, as provided by medicinal mushroom extract.
