Extract from Martin's Guide to Medicinal Mushrooms:


Main active components
Polysaccharides are the principal active components in Maitake, with several fractions, including:
D-fraction and MD-fraction, showing strong immunological activity (1) (2).

Traditional use
Most traditional sources do not mention Maitake and it appears that it was often not differentiated from Umbrella Polypore (also known as Grifola umbellata), of which it is said that ‘long term use makes one feel happy and vigorous and look younger’.

Main Health Benefits

Impressive results have been reported from the use of Maitake polysaccharide extracts, or combinations of polysaccharide extracts and fruiting body, with one study using 40-100mg MDfraction and 4-6g powdered fruiting body reporting cancer regression or significant symptom improvement in 58% of liver cancer patients, 68% of breast cancer patients and 62% of lung cancer patients. Similar results have been reported using combinations of D-fraction and powdered fruiting body and improvements in immunecompetent cell activities have also been reported when taken in conjunction with chemotherapy (3, 4). Polysaccharide extracts of Umbrella Polypore are also licensed as anti-cancer agents in China, with improved treatment outcomes and quality of life indicators in a number of cancers, including: lung, liver, leukaemia, bladder, nose and throat (5).

Several studies report significant improvement in blood sugar levels in type II diabetes patients from using purified Maitake polysaccharides. Positive results have also been reported from inclusion of crude Maitake powder in the diet of diabetic animal models (20% of food, or 1g/day in a mouse model) (6) (7).

Polycystic Ovary Syndrome (PCOS)
In the majority of cases, PCOS is associated with some level of insulin resistance and Maitake polysaccharide extracts also show promise as agents for helping address this condition(8). In one Japanese study, ovulation was observed in 20 of the 26 women given a Maitake polysaccharide extract and 6 of 8 women who failed to ovulate after being treated with clomiphene citrate did so after being given the polysaccharide extract. In addition, all 3 women who expressed an interest in becoming pregnant were able to do so (9).

Polysaccharide extracts or combinations of extract and fruiting body have been favoured clinically at
doses of 3-6g/day.
