Lentinan is a complex polysaccharide that possesses immunostimulating anti-tumor properties. Lentinan was isolated from edible shiitake mushrooms that have been used in traditional Asian cooking and herbal medicine. Shiitake has been renowned in Japan and China as a food and medicine for thousands of years and is now commonplace throughout the world. Extracts of these mushrooms are being incorporated into over-the-counter dietary supplements designed to improve the status of the immune system.

Botany :- Lentinan is a polysaccharide derived from the vegetative parts of the edible Japanese shiitake mushroom. It is the cell wall constituent extracted from the fruiting bodies or mycelium of L. edodes.The light, amber fungi are found on fallen broadleaf trees, such as chestnut, beech, or mulberry. They have de-current, even, or ragged gills, a stem, and are covered with delicate, white flocking. Shiitake mushrooms are commonly sold in food markets in the Orient and are now widely available in the United States, Canada, and Europe.
