Introduction

When it comes to culinary and medicinal value, not all mushrooms are created equal. Of the more than 10,000 known varieties, only a handful are backed by substantial research supporting both their health benefits and edibility. Maitake (Grifola frondosa) stands out as one of the rare mushrooms that is both delicious and medicinal.

A Mushroom Worth Dancing For

Worth dancing for? That is a unusual way to characterize a fungus! But that is literally how the Maitake was named. The Japanese were so delighted when they found this mushroom that they named it maitake, meaning "dancing mushroom" (mai= dance, take= mushroom), reflecting the joy people felt upon discovering it in the wild. In China, it is known as hui-shu-hua or “grey tree flower” for its floral appearance. Maitake also goes by other names such as hen-of-the-woods, sheep’s head, and cloud mushroom in North America and Europe.

Maitake has long been revered in Asia for its powerful healing properties which also made it worth dancing for. Over the past decade, it has also gained attention for its healing properties in North America and Europe and been the subject of numerous scientific studies. How do you find maitake? Maitake has specific habitat where it fruits. Maitake typically grows around the stumps or trunks of hardwood trees. It thrives in the northeastern regions of Japan and the temperate forests of North America, Europe, and Asia. Today, it is also widely cultivated and commonly found at growers’ markets and gourmet grocery stores. It is also available as capsule form in health food stores and online.

Overview

Maitake is an attractive, multibranched, coral-like fungus. As a polypore mushroom, it features tiny pores on the underside of its many caps. It grows at the base of large hardwood trees and has no toxic look-alikes, making it a safe mushroom for foraging [1].

Biologically, maitake is a saprobic fungus, meaning it feeds on decomposing organic matter. Its mycelium lives inside dead or decaying trees and sometimes as a weak parasite on living ones. When mature, it produces a fruiting body—what we recognize as the maitake mushroom.

Saprobic fungi like maitake are crucial to forest ecosystems because they help recycle nutrients by breaking down wood and other organic material.

Form, Color, and Size

Maitake grows from an underground tuber-like base into a tight, clustered formation. Its caps are:

• Spoon-shaped with wavy margins
• Grey to grey-brown in color with a milky white central stalk
• Moderate to large, typically ranging from 6 to 20 inches across (sometimes even larger)

The underside of each cap contains fine pores instead of gills, and the base of mushroom has a thick, white, dense structure.

Fragrance and Edibility

Maitake has an earthy, peppery aroma and a rich unami flavor. Its meaty, slightly chewy texture makes it a favorite in vegetarian dishes and an excellent meat substitute. The flavor is far more complex than that of common button mushrooms and works well in both simple and elaborate dishes.

How to Know if Maitake Is Spoiled

Have you ever wondered if the mushroom in the refrigerator is still good to eat? Like all mushrooms, maitake is perishable. Signs that it has spoiled include:

• Excessive browning or sliminess
• Foul or sour odor
• Wet or soggy texture, especially at the base of the package

A little discoloration is okay, but if the mushroom is dark, mushy, or smells bad, it should be discarded.

Storage Tips

There are some basic principles for storing maitake.

• Do not wash until ready to use (moisture reduces shelf life and flavor)
• Store in a paper bag in the refrigerator, not in plastic
• Keeps fresh for up to one week.

At the store or in the forest, choose maitake that is firm and plump with a pleasant earthy smell.

Cooking Tips

The sky is the limit for using maitake in the kitchen. Maitake is a versatile and tasty addition to a variety of dishes.

• Can be sautéed, stir-fried, marinated, grilled, or baked.
• Adds depth to meat, fish, pasta, soups, and stews.
• Can be used fresh or dried and rehydrated.

Natural Habitat

Maitake grows in the late summer and fall in temperate forests across Asia, Europe, and the United States. It tends to fruit on the same hardwood stumps, standing dead hardwoods or decayed hardwood logs year after year.

Cultivation

Maitake is cultivated worldwide using controlled methods. Cultivators inoculate sterilized hardwood sawdust (supplemented with wheat or oat bran) with maitake spawn (the stringy mycelium of the maitake). Then cultivators maintain specific temperature, humidity, and air circulation for optimal fruiting.This controlled environment mimics its natural conditions and ensures consistent, high-quality harvests.

Capsules

Maitake is not only available as fresh mushrooms but as dry medicinal powder in capsule form. For people with a busy lifestyle this is an option to get the medicinal benefits without preparing a meal. Capsules are available online and in many health food stores, generally as 1000mg/capsules. For a daily therapeutic dose of 3000 mg, 3 capsules per day can be taken either morning or night.

Medicinal Properties

While maitake mushrooms are well-known as a delicious culinary ingredient, they are also gaining recognition as a powerful medicinal mushroom. Long used in traditional Asian medicine, maitake has recently garnered increased interest in Western research and pharmaceutical communities for its diverse health-promoting properties. [2,3,4,5,6]

What specifically are the compounds that fuel maitake’s positive effect on health? Maitake contains a range of bioactive compounds that can positively affect health, including:

• Antioxidants
• Polysaccharides
• Beta-glucans and phenolic compounds
• Ergosterols and ergothioneine
• Triterpenes
• Vitamins B and C
• Copper
• Potassium
• Fiber
• Essential minerals
• Amino acids

In addition, maitake mushrooms are:

• Fat-free
• Low in sodium
• Low in calories
• Cholesterol-free

Rich in dietary fiber, vitamin D, B vitamins (including niacin and riboflavin), and essential minerals, maitake supports bone health, metabolic function, gut health, and may help prevent anemia. Notably, they contain higher levels of vitamin D compared to many other mushrooms and most foods.

While maitake is nutritious, it's the specialized compounds—particularly polysaccharides and beta-glucans—that offer profound health effects. Studies have shown these and other substances exhibit antioxidant, antitumor, anti-inflammatory, cholesterol-lowering, and anti-diabetic properties.

Let’s explore the emerging science behind these benefits:

Potential Health Benefits of Maitake Mushrooms

Reduce Inflammation

Maitake mushroom extracts have demonstrated anti-inflammatory effects in laboratory studies. Certain compounds in maitake have been shown to inhibit inflammation-related enzymes, with results comparable to non-steroidal anti-inflammatory drugs (NSAIDs) .[7]. Additionally, these extracts reduced several other pro-inflammatory compounds in lab settings. However, human clinical studies are still needed to confirm these effects.

Anticancer Properties

Since the 1980s, maitake mushrooms have been researched for their antitumor properties. While most studies have been conducted on animals or in lab environments, a few small human trials show promise.[8]

• Beta-glucans from maitake have demonstrated the ability to inhibit tumor growth in animals and reduce tumor progression in human patients.
• One study involving 10 cancer patients showed that maitake supplementation helped reduce tumor markers and prevented metastasis.
• In mice, Roldan-Deamicis et al. 2016, found maitake beta-glucans reduced breast carcinogenesis, blocked tumor invasiveness, reduced angiogenesis, and increased overall survival[9]
• A Phase I/II clinical trial by Deng et al. (2009) in 34 postmenopausal breast cancer patients found a statistically significant increase in immune function from maitake polysaccharide extract (p < 0.0005).[10].

Maitake's anticancer potential is believed to stem from its ability to stimulate the immune system, although some evidence suggests it may also act directly on cancer cells.

Lower Cholesterol

Animal studies suggest maitake mushrooms can lower cholesterol and triglycerides:

• In one study, Ding et al. 2016, found rats on a high-cholesterol diet given maitake mushrooms for five weeks had significantly reduced LDL (“bad”) cholesterol and triglyceride levels compared to controls.[11]
• This research showed maitake helped the liver metabolize cholesterol and reduced systolic blood pressure.
• Beta-glucans appear to reduce LDL without affecting HDL (“good”) cholesterol or
• triglycerides.

Though promising, these findings are limited to animal models—human studies are needed to confirm cardiovascular benefits.

Help Manage Type 2 Diabetes

Polysaccharides in maitake mushrooms may help regulate blood sugar levels and improve insulin sensitivity .[12]

• In diabetic mice, maitake decreased fasting blood glucose and improved glucose tolerance and lipid profiles.
• Other studies found maitake improved insulin resistance in diabetic rats and reduced inflammation while improving gut microbiota .[13]

These findings support further investigation into maitake as a complementary approach to managing type 2 diabetes.

Support Brain Health

Emerging research suggests maitake mushrooms have neuroprotective potential:

• In lab studies, Tripodi et al. 2022, found maitake extracts displayed anti-aging and brain- protective effects in yeast and fruit flies, likely dueto their high beta-glucan content [14].

• A 2023 review highlighted maitake's antioxidant and anti-inflammatory properties, which may protect neurons and stimulate neurogenesis (the formation of new brain cells) [15].

Maitake and its extracts appear to hold many health benefits, including immune-modulating effects. Several edible mushrooms have been shown to contain rare and exotic compounds that exhibit positive effects on brain cells both in vitro and in vivo [16] which could also play a role in post-traumatic brain injury. These effects indicate maitake or maitake extracts could one day play a role in preventing neurodegenerative diseases, but research is still in early stages further studies—especially human studies—are needed.

Foster a Healthy Gut Microbiota

Recent research indicates maitake mushrooms support digestive health by acting as a prebiotic. Prebiotics provide nourishment for beneficial gut bacteria. They also contribute to the production of short-chain fatty acids (SCFAs)—bioactive compounds formed when non-digestible mushroom polysaccharides, such as beta-glucans, reach the colon intact. Once in the colon, these polysaccharides are fermented by beneficial microbes, boosting probiotic populations, and suppressing harmful pathogens. This promotes a more diverse and stable gut microbiota, which has been linked to stronger immune function, reduced inflammation, and protection against certain metabolic diseases [18,19,20].

Maitake fosters a healthy gut ecosystem through multiple mechanisms:

• Prebiotic Action: Rich in polysaccharides like beta-glucans, maitake resists digestion in the stomach and small intestine, reaching the colon to selectively feed beneficial bacteria.
• SCFA Production: Fermentation of these polysaccharides produces SCFAs such as butyrate, propionate, and acetate, which play key roles in gut and metabolic health.
• Immune Regulation: By increasing SCFAs and beneficial bacteria, maitake helps regulate immune responses, promoting balance and reducing gut inflammation.
• Gut Barrier Support: SCFAs strengthen the intestinal lining, improve gut barrier integrity, and enhance nutrient absorption.

Who Should Avoid Maitake?

While maitake mushrooms are generally considered safe, there are important considerations:

• Low Blood Pressure: Maitake may lower blood pressure, which could be problematic for individuals already prone to hypotension.
• Surgery: Because maitake may lower blood sugar and thin the blood, stop using it at least two weeks before surgery.
• Warfarin or Blood Thinners: Maitake may enhance the effects of anticoagulants like warfarin, increasing the risk of bleeding. Speak with your healthcare provider if you’re on blood thinners.
• Digestive Sensitivity: Eating raw maitake can cause stomach upset or be hard to digest.
• Allergies: Though rare, allergic reactions to maitake are possible.
• Pregnancy and Breastfeeding: There is insufficient evidence about the safety of maitake during pregnancy or lactation. Consult your healthcare provider.

Conclusion

Maitake has an earthy, peppery aroma and a rich umami flavor that makes it one of the world’s most prized edible mushrooms. The flavor is far more complex than that of common button mushrooms and works well in both simple and elaborate dishes. But maitake is more than just a flavorful addition to the kitchen—it is a potent functional food with a growing body of evidence supporting its medicinal value. Long revered in Eastern traditions and now gaining prominence in Western research, maitake contains a diverse array of bioactive compounds, including beta- glucans, polysaccharides, antioxidants, and essential nutrients.

Maitake’s remarkable array of bioactive compounds work in many ways to support health. Research shows they can strengthen the immune system, calm inflammation, balance blood sugar, improve cholesterol levels, gut health, and even protect brain function. Early studies — including a few promising human trials — suggest maitake may also help in the fight against cancer by triggering the self-destruction of certain cancer cells and empowering the immune system to target malignant ones [8,9,10]. While science is still uncovering the full extent of its benefits, maitake’s rich nutritional profile and potent medicinal properties make it a standout candidate for the next generation of nutraceuticals.

There is much still left to learn about maitake. Most of the current scientific evidence is drawn from laboratory and animal studies, the results are promising and highlight the need for larger, well-designed human clinical trials. At the same time, maitake remains a delicious, nutritious, and versatile mushroom that can be safely enjoyed in most diets. As with all supplements and functional foods, individuals with specific medical conditions or those on certain medications should consult healthcare professionals before regular use.

In sum, maitake, the “dancing mushroom”, offers a rare combination of culinary delight and potential therapeutic benefit, making it a mushroom worth celebrating in both science and cuisine. The current evidence, along with the growing consumer interest in natural health solutions, positions maitake mushroom as a promising ingredient for the development of innovative nutraceutical products. These products aimed at addressing a range of health concerns, from immune support and chronic disease prevention [20]. Its integration into modern healthcare and nutrition may only deepen as future research continues to unlock its medicinal secrets.
