Health Applications
- Immune system support
- Cardiovascular health
- High cholesterol
History and Traditional Use
Maitake is known in Japan as "the dancing mushroom," because,
according to legend, mushroom hunters who found the rare fungus
were said to dance for joy. For centuries, the mushroom has been
valued for its unique culinary and medicinal properties. During
the feudal era, maitake mushrooms were worth their weight in silver
and were used as a form of currency.1
Chemical Composition
Maitake contains a complex polysaccharide compound known as beta-D-glucan,
which is believed to be responsible for the mushroom's physiological
activity.
Contemporary Uses
While maitake remains a popular culinary mushroom, medicinally
it is used as a general tonic to strengthen the immune system
and promote cardiovascular health. Animal studies indicate that
maitake may help reduce high blood pressure levels2,3
and high cholesterol levels,3-5 apparently
by improving lipid metabolism. Other studies suggest that maitake
may help protect the liver against certain toxins,6
and may also have an antidiabetic effect.7
Several studies indicate that beta-D-glucans from maitake have
antitumor activity in mice8-14 however, most
of these effects were produced with injected forms and were not
observed with oral administration.13,14 One
study conducted on laboratory mice suggests that consuming maitake
may protect against developing bladder cancer, but this has not
been demonstrated in human subjects.15
Dosage/Toxicity
Maitake supplements are available in a variety of potencies, with
dosage recommendations printed on the labelling. Maitake mushrooms
are consumed in large quantities as food, and are not associated
with any toxicity. |
