Habitat and natural environment of Shiitake mushrooms:Lentinus edodes.:
It is called "elixir of life" by Chinese emperors during the dynasty Ming. It slowed down their ageing and increased their vitality. Since the 40s, it is the object of traditional cultures in China.
Mushroom refers to the conspicuous umbrella-shaped fruiting body (sporophore) of certain fungi, typically of the order Agaricales in the class Basidiomycetes but also of some other groups. Popularly, the term mushroom is used to identify the edible sporophores.
Umbrella-shaped sporophores are found chiefly in the agaric family (Agaricaceae), members of which bear thin, bladelike gills on the undersurface of the cap from which the spores are shed. The sporophore of an agaric consists of a cap and stalk. The sporophore emerges from an extensive underground network of threadlike strands. An example of an agaric is the honey mushroom (Armillaria mellea). Mushroom may live hundreds of years or die in a few months, depending on the available food supply. As long as nourishment is available and temperature and moisture are suitable, a mushroom will produce a new crop of sporophores each year during its fruiting season.
Wu Ri, a physician from the Chinese Ming Dynasty era (A.D. 1368~1644), wrote extensively about this mushroom, noting its ability to increase energy, cure colds, and eliminate worms.
The shiitake mushroom is considered to be the finest edible mushroom in Asia, where it has been used for over 2,000 years. Shiitake mushrooms are cultivated on logs, dead tree trunks, and sawdust. Shiitakes range in color from tan to dark brown, and have broad, umbrella-shaped caps, wide-open veils, and tan gills. Shiitake caps have a soft, spongy texture. When cooked, these mushrooms have a rich, smoky flavor and a meat-like texture.
Shiitake are available year-round in many grocery stores and in Asian markets. Shiitake mushroom are sold fresh and dried.
Shiitake Mushroom is also known by the names Oak Mushroom, Oriental Black Mushroom, and Glossagyne. Shiitake grows on the trunks or stumps of trees. In the wild, this light amber fungus is also found on fallen hardwood trees. Shiitake has been revered in China and Korea as both a food and medicinal herb for thousands of years. Wu Ri, a famous physician from the Chinese Ming Dynasty (A.D. 1368~644), wrote extensively about this mushroom, noting its ability to increase energy, cure colds, and eliminate worms. Wild Shiitake Mushrooms are native to China, and other Asian countries. Shiitake is widely cultivated throughout the world, including the United States. The fruiting body is used medicinally. Mushrooms have been valued as both food and medicine throughout the world, but until recently, many in the West associated all mushrooms with poison. The recent surge of Western interest in medicinal mushrooms shows that this attitude may be changing, however.
Shiitake products containing LEM, a polysaccharide-rich extract from the Shiitake Mushroom, and similar extracts from Maitake Mushroom, are currently undergoing trials in the United States to see whether they are effective treatments for various cancers and AIDS. Currently, the total world worth of the pharmaceutical and nutraceutical products derived from mushrooms is estimated at more than $1.2 billion. A vast amount of research into Shiitake's medicinal properties has been completed and shows that it has the ability to fight tumors and viruses and enhance the immune system.
Primary chemical constituents of Shiitake include Polysaccharide (lentinan), eritadenin, proteins, fatty acids, and vitamins D, B-2, B-12. The proteins contain all of the essential amino acids, and most commonly occurring non-essential amino acids and amides. The fatty acids are largely unsaturated, and Shiitake's are rich in vitamins and minerals. Key therapeutic substances also present are glucans, a major constituent of the cell walls. Shiitake also yields Lentinan, a beta-1,3-linked glucan polysaccharide with a molecular weight of 1 million. Lentinan reversed tumor growth when injected in mice. It acts by stimulating the immune system, rather than by direct action on the tumor. Because of its large molecular size, Lentinan is not absorbed efficiently when taken orally, but some is absorbed. Lentinan activates the alternative complement pathway, stimulating the macrophages, thus inhibiting tumor growth. It also may activate interleukin-1 secretion, which helps trigger T lymphocytes. Shiitake is believed to stimulate interferon production. Eritadenine, a purine alkaloid from Shiitake, is similar to nucleotides in structure, and lowers cholesterol in animal studies.
