Shiitake (Lentinula edodes) is the world’s most popular edible mushroom and has been used for thousands of years in Asia to improve health. Shiitake contain many medicinal compounds including terpenoids, sterols, lipids and significant levels of vitamins B1, B2, B12, C, D, and E along with polysaccharides such as lentinan. Shiitake is a rich source of the immunostimulatory β-glucans, which bestow anti-viral activity by inhibiting viral reverse transcriptase as well as modulating humoral and cellular mediators of interleukin, activating macrophages, T-helper and natural killer cells, making shiitake useful for treating various cancers and protecting against bacteria, viruses, fungi and parasites.
