Himematsutake
Also known as: Agaricus blazei Murrill, Agaricus brasiliensis, Himematsutake, Royal Sun Agaricus, Brazilian Mushroom, Agaricus blazei
Overview
Agaricus blazei, also known as Himematsutake or Royal Sun Agaricus, is an edible mushroom native to Brazil and cultivated globally for its medicinal properties. It is traditionally used to modulate the immune system, reduce inflammation, and potentially combat cancer. This mushroom is rich in polysaccharides, particularly beta-glucans, which are believed to be responsible for its immunomodulatory effects. While research shows promise, systematic reviews and meta-analyses are limited, resulting in variable evidence quality. It is available in various forms, including liquid extracts and capsules, and is often consumed as a dietary supplement to support overall health and well-being. Preliminary studies suggest potential benefits for individuals with compromised immune systems or chronic inflammatory conditions. However, further robust research is needed to confirm these effects.
Benefits
Agaricus blazei primarily offers immunomodulatory and potential anticancer effects, along with improvements in quality of life. Studies, such as those using AndoSan™, an Agaricus blazei extract, have demonstrated improvements in clinical symptoms and reduced fatigue in ulcerative colitis patients. Preclinical studies suggest anti-inflammatory and antiallergic effects. It may particularly benefit individuals with compromised immune systems or chronic diseases. While moderate improvements in symptom scores and quality of life have been reported, more robust studies are needed to establish consistent effect sizes. Benefits may be observed within weeks of supplementation, but long-term effects require further investigation. The strength of evidence varies, with some studies showing promising results but others lacking robust methodology or large sample sizes.
How it works
Agaricus blazei primarily works by modulating the immune system through the activation of natural killer cells and the induction of cytokines like IL-12. Its polysaccharides, especially beta-glucans, interact with immune cells to enhance their activity. This interaction primarily affects the immune system, with potential impacts on cancer cells through apoptosis induction. Animal studies suggest that oral administration can stimulate immune responses, although human bioavailability data is limited. The mushroom's components engage with various biological pathways to promote immune function and potentially inhibit cancer cell growth.
Side effects
Agaricus blazei is generally considered safe, but potential liver toxicity has been reported in some cases. Common side effects are not well-documented, but gastrointestinal upset may occur. Uncommon side effects include the potential for allergic reactions. Rare side effects involve liver dysfunction. Limited data exists on drug interactions, but caution is advised with immunosuppressive drugs. It is contraindicated during pregnancy and breastfeeding due to insufficient safety data. Individuals with autoimmune diseases should consult healthcare providers before use. Monitoring for signs of liver dysfunction is recommended, and high doses should be approached with caution.
Dosage
The minimum effective dose of Agaricus blazei is not well-established, but extracts like AndoSan™ have been used at doses of 60 ml/day. Typical dosage ranges for extracts are between 30-60 ml per day. The maximum safe dose is not clearly defined, so high doses should be approached with caution. Consistent daily intake is recommended. Liquid extracts are commonly used, and bioavailability may vary based on extraction methods. No specific cofactors are required. It is important to adhere to recommended dosages and monitor for any adverse effects.
