Maitake
Grifola frondosa
Also called hen of the woods: a ruffled cluster that grows at the base of oaks in fall. Small human studies look at immune markers and blood sugar. One of the best-tasting wild mushrooms, and it cultivates well.
Historical Use and Context
Maitake means "dancing mushroom" in Japanese, from the story that foragers danced when they found one. Wild maitake was valuable enough that harvesters guarded their patches as family secrets, and in feudal Japan it was reportedly traded for its weight in silver.
Japan cracked commercial cultivation in the 1980s. Around the same time, Hiroaki Nanba isolated a beta-glucan fraction he called D-fraction, which drove most of the early immune research on maitake.
How to Cook Maitake
- Flavor
- Earthy, peppery, woodsy
- Texture
- Crisp, frilly edges with a tender core
- Best ways to cook
- Roast whole clusters at high heat until the edges crisp. Also great in soups and risotto.
- Pairs with
- Butter, thyme, parmesan, brown rice, eggs
- Prep tip
- Break into palm-size clusters along the natural seams. Brush off debris; rinse only if gritty.
- Storage
- Paper bag in the fridge, about a week.
Cooking isn't only about flavor. Mushroom cell walls are built from chitin, which is hard to digest raw. Heat breaks it down, which helps your body get at the beta-glucans and other compounds the research focuses on.
The Short Answer
May help support immune activity; blood sugar benefits so far shown in animals only.
Maitake is a great eating mushroom. Its extracts (including one called D-fraction) have been tested in small cancer trials that showed immune changes, and its blood sugar effects so far come from animal studies.
How Strong Is the Research?
Small human trials
How to Eat It
Fresh, as Food
Tear into pieces and roast or saute until the edges are crisp and it is hot all the way through.
Dried
Soak in warm water for about 20 minutes, then add to soups, broths or rice.
A Normal Serving
As food, a normal serving is about 1 cup (roughly 70 g) of fresh maitake. The human trials used concentrated extracts (0.1 to 5 mg per kg of body weight, twice a day), not whole mushrooms.
When You Might Notice
Immune changes in the trials were measured after 3 weeks (breast cancer study) and 12 weeks (blood disorder study). There is no human data on how long food amounts take to do anything.
⚠ Who Should Skip It or Ask Your Doctor First
- Diabetes medicines: maitake lowered blood sugar in animal studies, so watch your levels if you add extracts on top of medication.
- Blood thinners like warfarin: medical references flag a possible interaction with maitake extracts, so check with a doctor before taking them.
- People being treated for cancer: in one trial, maitake extract raised some immune measures and lowered others, so only use extracts with your oncologist's okay.
- Mushroom allergies: skip it if other mushrooms have caused reactions.
- Pregnancy or breastfeeding: cooked maitake as food is common, but skip extracts since they have not been tested.
Buying, Storing and Cooking
1
Firm, Fresh Clusters
Look for a tight, dry, grayish-brown cluster with no mushy or dark wet spots.
2
Store and Use Quickly
Keep fresh maitake in a paper bag in the fridge and cook within 5 to 7 days.
3
Cook It Well
Like other mushrooms, maitake is easier to digest and safer cooked than raw.

The Research in Plain English
2009 · 34 women after breast cancer treatment · Phase I/II trial
Women took a maitake polysaccharide extract at doses from 0.1 to 5 mg per kg twice a day for 3 weeks. Some immune measures went up and others went down, and no serious side effects were linked to the extract. Small, no placebo, and focused on safety. Read the study ↗
2015 · About 20 adults with a bone marrow disorder (MDS) · Phase II trial
People with myelodysplastic syndrome (a bone marrow disorder) took maitake extract at 3 mg per kg twice a day for 12 weeks. Their white blood cells worked better in lab tests, and the extract was well tolerated. Small and without a placebo group. Read the study ↗
2001 · Diabetic rats · Animal study
In rats, eating maitake improved how their bodies handled sugar (glucose tolerance). This has not been tested the same way in people. Read the study ↗
