Meaning "Dancing Mushroom" in Japanese, Maitake's name is said to have originated from people dancing from happiness after finding it in the wild as it has some incredible benefits. It was a highly valued commodity in feudal Japan, where local lords would trade their subjects an equivalent weight in silver for Maitake .
Where does it come from?
Maitake can be found growing in parts of Japan, China, and North America. At the bottom of Oak, Elk, and Maple trees are where Maitake is typically grown, and it is more common in autumn months.
How does it help?
Effect on Type II Diabetes
Maitake is best known for its healing properties against diabetes and hypertension.
Maitake contains alpha-glucan from the fruiting body in which has an anti-diabetic effect. Studies have shown that treatment with Maitake alpha-glucan significantly decreased the body weight, level of fasting plasma glucose, GSP, serum insulin, triglycerides, cholesterol, free fatty acid, and MDA content in livers .
Like other medicinal mushrooms, Maitake contains a complex sugar called beta-glucan . Beta-glucans are found in the cell walls of bacteria, fungi, yeasts, algae, lichens, and plants, and are sometimes used as medicine.
Beta-glucans help reduce your cholesterol, which improves artery function and the overall health of your cardiovascular system, lowering your risk of heart disease 
Maitake has been shown to suppress tumor growth, as well as fight reproduction of cancer cells.
Extracted from the Maitake mushroom, Maitake D-Fraction has been reported to have an anti-tumor effect. This is possible as it enhances the immune system through the activation of T cells, macrophages, and natural killer cells .
Recent evidence has shown that depression is related to immune regulation, and it has been proposed that the bioactive polysaccharides or peptides may be responsible for the antidepressant effects of Maitake.
Recent evidence has shown that immune cells and their signaling play a major role in the pathophysiology of major depressive disorder .
