Reishi Mushroom Health Benefits
The reishi mushroom (Ganoderma lucidum) grows on deciduous trees, at the base and stumps, especially maple trees. It is considered relatively rare, since only two or three such trees will have the growth.
Today, it is grown both indoors under sterile conditions and outdoors on woodchips or logs.Medicinal UsesReishi mushrooms have various healing properties. Here are a few: - It is an antioxidant, increasing oxygenation of the blood.

Possible upset stomach. These symptoms clear up upon discontinuation of reishi.

This mushroom is very woody and it’s better to cook it before consuming. There’s a form of cellulose in the mushroom walls called chitin which may cause discomfort to some people if eaten raw. Cooking helps to break this down. The chitin is a form of dietary fiber, and the fiber of fungi has been shown to be helpful in reducing cholesterol levels.
***Caution***I don’t recommend going out into the woods to find your own mushrooms. This can be dangerous, as some are very toxic. Get them from a reputable source or use a prepared extract. Return from Reishi Mushroom to Healthy Foods.
