Maitake (Grifola frondosa)
The maitake (Grifola frondosa) is a medicinal mushroom from the Sparassoidaceae family. It has been valued in traditional Asian botany for centuries. Its Japanese name means "dancing mushroom"—according to legend, people would dance for joy upon finding it. In Europe, it is also known as the tinder fungus.
Botanical characteristics
- Prefers to grow at the base of deciduous trees, especially oaks
- Forms large, cluster-shaped fruiting bodies with many fan-shaped, grey-brown caps
- Both fruiting bodies and mycelium are processed in food supplements
Ingredients
Maitake contains among other things:
- Beta-glucans (polysaccharide compounds)
- Other polysaccharides such as Grifolan
- Ergosterol (precursor of vitamin D2)
- Amino acids, minerals and B vitamins in small amounts
Beta-glucans in particular are the focus of scientific research.
