Maitake mushrooms (Grifola frondosa) have a long history of use in traditional medicine for their immune-enhancing and health-promoting properties. Modern research supports these traditional uses, particularly for immune support, cancer prevention, blood sugar regulation, cardiovascular health, and anti-inflammatory effects. The bioactive compounds in Maitake contribute to its reputation as a potent natural remedy in both traditional and modern medicine.

What are Maitake Mushrooms?
Maitake mushrooms, also known as hen of the woods, king of mushrooms and cloud mushroom, have a distinct frond-like structure with overlapping clusters of fan-shaped caps. The caps are usually brownish-gray with white undersides and can grow quite large, sometimes reaching up to several kilograms in weight.
Maitake mushrooms are native to Japan, North America, and Europe, where they grow at the base of oak, elm, and other hardwood trees. They are typically found in temperate forests, particularly in late summer and early autumn.
Maitake’s Primary Compounds
Maitake mushrooms contain several bioactive compounds, including:
Polysaccharides: Beta-glucans and other polysaccharides with immune-enhancing properties. Maitake D-fraction or MDF has been a primary compound involved in significant immunity and cancer studies.
Grifolin: Which has shown anti-tumor effects in some studies.
Sterols: Such as ergosterol, which contributes to overall health.
Antioxidants: Various phenolic compounds with antioxidant activity.
Maitake Traditional Medicinal Uses
Maitake mushrooms have been used in traditional medicine systems, particularly in:
Japanese Medicine: Known as Maitake or "dancing mushroom," it has been used to boost the immune system, regulate blood sugar levels, and support overall health.
Traditional Chinese Medicine (TCM): Used similarly for its immune-modulating and health-promoting properties.
Health Benefits of Maitake
Research has indicated several potential health benefits of Maitake mushrooms:
Immune System Support
Maitake mushrooms enhance immune function by stimulating various immune cells, including macrophages and natural killer cells.
Anti-Cancer Properties
Compounds like grifolin and beta-glucans have shown potential anti-cancer effects, including inhibiting tumor growth and metastasis.
Blood Sugar Regulation
Maitake mushrooms may help regulate blood sugar levels by improving insulin sensitivity and reducing insulin resistance.
Cardiovascular Health
Some studies suggest that Maitake can help lower cholesterol levels and reduce the risk of cardiovascular disease.
Anti-Inflammatory Effects
Maitake mushrooms have significant anti-inflammatory properties, which can help reduce inflammation and support overall health.
Weight Management
Maitake extract has been investigated for its potential to aid in weight management by promoting satiety and fat metabolism.
Human Clinical Research
Many studies in the laboratory have confirmed the above-mentioned health benefits of maitake. In addition, a number of human studies have confirmed these results. Here are a few of them:
A 2023 review of clinical research from Italy’s University of Insubria found that maitake significantly inhibited breast cancer tumor cells from metastasizing.
A 2020 study from the University of Oslo found that maitake mushrooms was able to reduce tumor development and growth.
In a clinical trial of 34 postmenopausal breast cancer patients following conventional treatment, maitake liquid extract significantly boosted their immune function.
A 2015 study from New York’s Memorial Sloan Kettering Cancer Center tested 21 patients with Myelodysplastic syndromes (MDS). After being given a maitake supplement every day for 12 weeks, the patients test results showed significant symptom reduction. The researchers concluded:
“Enhanced in vitro neutrophil and monocyte function following treatment demonstrate that Maitake has beneficial immunomodulatory potential in MDS.”
A 2010 study from Japan tested 26 women with polycystic ovary syndrome (PCOS) who failed clomiphene citrate therapy. They found that maitake extract significantly boosted their ovulation. The researchers concluded:
“The present study suggests that MSX alone may induce ovulation in PCOS patients and may be useful as an adjunct therapy for patients who failed first-line CC treatment.”
