Quick Summary
Agaricus subrufescens, commonly known as Agaricus Blazei, is an edible mushroom species researched for its polysaccharides and bioactive compounds with potential immunomodulatory, antioxidant, and liver-protective effects. Scientific studies to date include animal models and some human clinical trials mostly on related mushroom polysaccharides, but direct human clinical evidence specifically on A. subrufescens remains limited. Research also explores its nutritional composition and applications in food fortification and immune modulation.
What Is It?
Agaricus Blazei (Agaricus subrufescens) is a species of edible mushroom native to Brazil but also cultivated elsewhere. It is characterized by its rich content of polysaccharides and other bioactive compounds that have attracted interest for potential health-related properties.
Traditional Uses
Traditionally, Agaricus Blazei has been consumed as a food and for its believed health-promoting properties, particularly in folk medicine settings. It is often used for general well-being and immune support although specific traditional medical uses vary by region and are not well documented in clinical literature.
Active Compounds
- Polysaccharides (including glucans and heteroglycans)
- Proteins
- Ergosterol (a precursor to vitamin D2)
- Other nutrients with antioxidant potential
Potential Benefits with Evidence Levels
- Possible Liver Protection (Animal evidence): Polysaccharides from Agaricus subrufescens demonstrated significant alleviation of alcoholic liver injury in mouse models, showing reductions in serum liver enzymes and oxidative stress markers.
[41976536] - Immune Modulation (Animal evidence): A blend including A. subrufescens polysaccharide fermented products affected cytokine expression and immune cell profiles in post-weaning piglets.
[34886904] - Nutritional Value and Potential Antioxidant Properties (Preclinical and compositional studies): Contains polysaccharides, proteins, ergosterol, and other nutrients that may provide antioxidant and immunomodulatory benefits.
[35910346], [41154052], [29082241], [40427401], [41008174] - General Immunomodulatory Effects of Mushroom Polysaccharides (Mixed animal and limited human clinical evidence): Oral polysaccharides from various mushrooms, including glucans and heteroglycans, have demonstrated immunomodulatory effects; however, these findings are not necessarily specific to A. subrufescens.

Side Effects
Limited data are available specifically on side effects of Agaricus subrufescens. Related medicinal mushrooms have reported only mild side effects in some cases. There are no direct reports of severe adverse effects for A. subrufescens in current studies.
Drug Interactions
No specific evidence from clinical studies exists regarding drug interactions with Agaricus subrufescens components or polysaccharides. Potential interactions remain unclear and require further research.
Who Should Avoid It
People with known mushroom allergies or specific medical conditions should approach use cautiously due to insufficient safety data. Safety during pregnancy and breastfeeding has not been established, so use should be avoided or done under medical supervision in these populations.
Evidence Limitations
The evidence base for Agaricus subrufescens primarily includes preclinical animal studies and compositional analyses with sparse direct human clinical trials. Immunomodulatory and liver protective effects require confirmation in rigorously designed human studies. Safety, adverse effect profiles, and drug interactions are inadequately characterized in humans. Findings from related mushroom species or polysaccharide extracts may not directly apply to A. subrufescens.
