Lion’s Mane is the name given to the Hericium erinaceus mushroom, a great, white mushroom that grows on trees and looks like the mane of a lion. Lion’s Mane has a very unique look: it’s a member of a group of mushrooms called ‘tooth fungi,’ named after the long, tooth-like projections that make up the fruiting body of the mushroom. Lion’s Mane ends up looking shaggy and delicate, with hundreds of toothy white extrusions hanging down towards the forest floor. Lion’s Mane is considered both a culinary and medicinal mushroom. It can be cooked and eaten in place of regular mushrooms, or dried and made into tea. Most medicinal or nootropic products use dried Lion’s Mane extract.
