Agaricus Blazei,
Immune Support with Agaricus Mushroom


Agaricus blazei (Agaricus subrufescens) is native to a small village, called Piedade, in the rain forests of Brazil.

It has long history of use by the native peoples who harvested and used the mushroom, calling it "Cogumelo do sol."

It was only recently brought to the forefront as an actual species when discovered by a local farmer in Brazil. In addition, a mycologists, W.A. Murrill, in the 1940's found it growing it Florida. It then began to be studied and cultivated for it's effects a very powerful medicinal mushroom variety.

Today it is commercially cultivated in Japan, China and Brazil, as well as the U.S.

Agaricus is a gilled mushroom, like shiitake, and tends to do well in warmer climates, growing on the borders of forests in plant debris or well manured grasslands.

The "wild" Crimini and Portabella mushrooms are also cultivars of this species.

In addition the cultivated "white button" mushrooms sold in most produce markets are also from the same Agaricus family but hold little medicinal value.

Agaricus Benefits for the Immune System

Agaricus has one of the highest concentrations of beta 1-6 glucan polysaccharides, up to 14-45%. This is even more than reishi, maitake and lions mane.

These polysaccharides promote "natural killer cells" (NK cells), macrophage, and polymorphonuclear leukocytes that inhibit tumor growth and stimulate immune system responses.

Agaricus subrufescens also contains alpha-glucan and produces yellowish metobolite that has bactericidal properties.

It has been traditionally used to treat many common diseases like atherosclerosis, hepatitis, hyperlipidemia, diabetes, dermatitis and cancer.

Asian countries use it in the prevention and treatment of cancer for it's anti-tumor health properties.
