Lion’s mane mushrooms (Hericium erinaceus) are white, globe-shaped fungi that have long, shaggy spines. People can eat them or take them in the form of supplements. Research suggests that they may offer a range of health benefits, including reduced inflammation and improved cognitive and heart health.
