We use shiitake mushrooms for their skin-conditioning and protecting properties. Packed with enzymes and vitamins including D, B2 and B12, they are said to be antibacterial, which may explain the healing qualities associated with them. They contain a potent antioxidant compound ergothioneine, thought to help counteract the effect of pollutants and increase oxygen efficiency.
Mushrooms have no leaves or seeds and reproduce by sowing spores, which develop thread-like roots called mycelia. Technically, the mycelium forms the main organism and the visible mushroom is its fruit. They are extremely fertile, with each mushroom producing trillions of spores in its lifetime. Since they have no leaves, they rely on the nutrients in the ground for nourishment.
