Maitake

Uses

Botanical names:
Grifola frondosa

Parts Used & Where Grown

Maitake is a very large mushroom, which grows deep in the mountains of northeastern Japan, as well as in North America and Europe. Famous for its taste and health benefits, maitake is also known as the “dancing mushroom.”1 Legend holds that those who found the rare mushroom began dancing with joy. Others attribute its name to the way the fruit bodies of the mushroom overlap each other, giving the appearance of dancing butterflies.

Maitake is extremely sensitive to environmental changes, which have presented many challenges to those cultivating this mushroom. However, Japanese farmers have succeeded in producing high-quality organic maitake mushrooms, allowing for wider availability both in Japan and the U.S. The fruiting body and mycelium of maitake are used medicinally.

What Are Star Ratings?

This supplement has been used in connection with the following health conditions:

Used for Why
1 Star
High Cholesterol
Refer to label instructions
Maitake mushroom polysaccharides have been found to improve lipid levels in animal studies.
A number of animal studies suggest that extracts from mushroom may lower cholesterol and triglyceride levels in the blood. Animal research further suggests maitake may inhibit development of atherosclerosis. This research is requires confirmation in clinical trials.
1 Star
High Triglycerides
Refer to label instructions
Studies suggest that the mushroom maitake may lower fat levels in the blood.

Animal studies suggest the mushroom may lower fat levels in the blood. However, this research is still preliminary and requires confirmation by controlled human trials.

1 Star
HIV and AIDS Support
Refer to label instructions
Maitake mushrooms contain immuno-modulating polysaccharides (including beta-D-glucan) that may be supportive for HIV infection.

mushrooms, which are currently being studied, contain immuno-modulating polysaccharides (including beta-D-glucan) that may be supportive for HIV infection.

1 Star
Immune Function
Refer to label instructions
Complex polysaccharides present in maitake appear to increase immune function.
Complex polysaccharides present in astragalus and in and coriolus mushrooms appear to act as “immunomodulators” and, as such, are being researched for their potential role in AIDS and cancer. Presently, the only human studies on astragalus indicate that it can prevent white blood cell numbers from falling in people given chemotherapy and radiotherapy and can elevate antibody levels in healthy people. Maitake has only been studied in animals as a way to increase immune function. The primary immuno-activating polysaccharide found in these mushrooms, beta-D-glucan, is well absorbed when taken orally and is currently under investigation as a supportive tool for HIV infection. Results from future research will improve the understanding of the possible benefits of these mushrooms and their constituents.
1 Star
Infection
Refer to label instructions
Maitake supports the immune system and protects against microbes.

Herbs that support a person’s immune system in the fight against microbes include the following: American ginseng, andrographis, Asian ginseng, astragalus, coriolus, eleuthero, ligustrum, , picrorhiza, reishi, schisandra, and shiitake.

Traditional Use (May Not Be Supported by Scientific Studies)

Historically, maitake has been used as a tonic and adaptogen (a substance that invigorates or strengthens the system). Along with other “medicinal” mushrooms, such as shiitake and reishi, maitake was used as a food to help promote wellness and vitality.

How It Works

Botanical names:
Grifola frondosa

How It Works

A common denominator among some mushrooms and some herbs is the presence of complex polysaccharides in their structure. These active constituents help support immune system function and are sometimes called immunomodulators. The polysaccharides present in maitake have a unique structure and are among the most powerful studied in test tubes to date.2 The primary polysaccharide, beta-D-glucan, is well absorbed when taken orally and is being studied as a potential tool for prevention and treatment of cancer and as a adjunctive treatment for HIV infection.3, 4 Animal studies suggest maitake may lower serum cholesterol and triglycerides.5, 6 However, this research is still preliminary and requires human trials for confirmation.

How to Use It

Maitake can be used as a food or tea and is also available as a capsule or tablet containing the entire fruiting body of the mushroom. For maitake, the fruit body is higher in polysaccharides than the mycelium, which is why it is recommended. Whole-mushroom maitake supplements, 3–7 grams per day, can be taken.7 Liquid maitake extracts with variable concentrations of polysaccharides are available, and should be taken as directed.
