Oyster mushroom have been around for centuries and have often been used for its medicinal and health benefits. These mushrooms became popular through Chinese medicine. There have been so many discoveries regarding the mushrooms’ medicinal properties that they have also been nicknamed ‘medicinal mushrooms’. These mushrooms have typically been more popular in Eastern and East Asian cuisines. Today, China is one of the largest producers and exporters of oyster mushrooms.

Health benefit

In clinical studies with diabetic patients, oyster mushroom significantly lowered total cholesterol, triglycerides, blood glucose and blood pressure. When the mushroom was withdrawn the levels rose again, and resuming intake brought them back down.

Numerous animal studies have also demonstrated oyster mushroom’s cholesterol-lowering ability. The addition of oyster mushroom to the diet of Syrian hamsters completely eliminated the increase in liver cholesterol and triglycerides caused by a chronic alcohol intake, bringing levels below those of the control group given a normal diet.

Oyster mushroom has demonstrated anti-cancer impact, inducing rapid apoptosis (cancer cell death) in studies. Oyster mushroom prevented the development of bladder cancer and maintained nearly normal levels of immune activity in mice exposed to a carcinogen, compared to a control group not given the mushroom. In vitro it showed a 76% inhibition rate against tumors.

The marked antioxidant activity of oyster mushroom has been shown to alleviate liver toxicity, returning levels of key antioxidant enzymes such as glutathione back to near normal after carcinogen exposure.

The antioxidant effects of oyster mushroom would seem to make it an excellent supplement for general health and anti-aging. Studies have found that oyster mushroom improved antioxidant status during aging. Whereas the brains, hearts, and organs of old rats had diminished levels of glutathione, vitamins C and E compared to young ones, administration of oyster mushroom raised levels to where they did not differ significantly from their younger counterparts.

Oyster mushroom may protect against age-related disorders involving free radicals, and was found to enhance gene expression of the important anti-oxidant enzyme catalase, which decreases free-radical induced protein oxidation.

Oyster mushroom has significant antibacterial properties. One study testing its in vitro antimicrobial activity found various forms of the extract had 50%, 87%, and 57.5% inhibition against candida, E. coli, and B. subtilis, respectively.
