Agaricus is a large genus of mushroom that has been cultivated around the world, mostly in Western Countries. It is one of the most studied/researched plants in the modern world probably because of its immunity building properties known to fight and cure certain illnesses, most notably cancer and any form of tumors.

Composition of Mushroom:

Water 90%
Protein 2-40%
Fat 2-8%
Carbohydrates 1-55%
Fibers 3-32 %
Ash 8-10%

General Health Benefits of Mushroom:
  • Lowers bad cholesterol
  • Prevents diabetes
  • Stimulates/Boosts Immune System
  • May prevent osteoporosis
  • Heals digestive and circulatory ailments
  • Reduces physical stress
  • May help reduce the spread of cancer (because of its polysaccharides contents)
According to different study results, its extract has potential medicinal components like polysaccharides such as beta glucan, ergosterol, lectin, sodium pyroglutamate among others which effectively fight chronic illnesses and circulatory problems.

There are several varieties of agaricus but the most researched and studied varieties are the following:

Agaricus Blazei - also known as Brazilian sun mushroom, it is an edible and medicinal mushroom and the most studied variety. It contains beta-glucan which many research studies claim can stimulate activity of natural killer cells
Agaricus Bisporus - also known as white mushroom, the most popular edible mushroom in some Western countries. It is known to possess potent antiproliferative effects on human epithelial cancer cells without any cytotoxity.
Agaricus Campestris - also known as meadow mushroom


But since human trials are limited and because the extraction process of these mushroom varieties differs from one company to another, it is uncertain which extracts or varieties, or how much dosage, provide the best and most effective results and people are admonished to take precautions.

Nevertheless, health benefits of Agaricus, particularly Agaricus Blazei, are approved by some organizations, most notably EFSA (European food and Safety Authority) which supports health claims that Agaricus "helps the natural defences/contributes to a normal immune response".

Many research studies claim that Agaricus blazei stimulates the immune system cells, Macrophage NK cells Leukocytes T-cells, Interleukins, Cytokines TNF-alpha interferons (body's virus fighting substance) which limit damages from radiation and mutagens. Another study done in Japan showing that Agaricus blazei extracts can slow or stop the growth of tumors or metastasis.

Agaricus has also been found to help detoxify the intestine and kidney. However, despite some of these research studies conducted yield favourable and satisfying results, it is still too early to recommend the supplements as medications to patients especially on prolonged periods. Some health professionals even warned not to take it more than three times a week.

Side Effects:

According to Dr. Sahelian's review, as of 2010, there are few side effects of Agaricus reported in Japan where it is widely taken as a dietary supplement, there were at least three cancer patients reportedly taking Agaricus supplements had liver damage. It may also induced severe hepatic dysfunction among cancer patients. These incidents on liver damage and severe hepatic dysfunction among cancer patients while taking Agaricus complicate the clinical-decision making process, thus, taking this supplement should be strictly limited to three times a week only and a week off period every month.
