AGARICUS BLAZEI POWDER
Dehydrated, finely ground Agaricus blazei mycelium cultured on organic whole oats.
*Royal Sun Agaricus
*Cogmelo de Dues (Mushroom of God)
In the same genus as the common button mushroom, this large and robust tropical species is found in Brazil and also in the southeastern United States. The thick, tall stem is whitish and bruises golden when handled or cut. The cap is whitish-brown with chocolate-brown gills and spores on the underside when mature. Both the fruitbodies and cultured mycelia have a wonderful, pervasive almond flavor and fragrance.
Known Active Constituents:
*Polysaccharides: A wide range of alpha- and alpha-D-glucans; beta- and beta-D-glucans
Medicinal Properties and Modes of Actions
The anti-tumor properties of this mushroom have been attributed to its high content of polysaccharides and antiangiogenic compounds. Such effects are thought to be exerted by immunopotentiation and/or direct inhibition of angiogenesis (the process whereby blood supply to tumors is increased) (Ahn et al., 2004; Lee et al., 2003;Takaku et al., 2002). Interestingly, a unique potein-bound polysaccharide ("Atom") was found to have no activity against four cancers in vitro (in a test tube)but had pronounced and significant activity in vivo (in a living creature)
(Ito et al. 1997). This suggests a host-mediated immune response mechanism.
Hot water extracted beta-glucans from Agaricus blazei show overall anti-diabetic activity including antihyperglcemic, antihypertriglyceridemic, anticholesterolemic, and antiarteriosclerotic activity (Kim et al., 2005). Agaricus blazei has been shown to stimulate and modulate the immune system. Fujiyama et al. (1999) reported that the beta-glucans in this mushroom activated the immune response to abnormal cells, but had no effect on normal cells.
