The Maitake is considered a particular marvel in Asia, already centuries ago. This was due in part to its unusual bush-like shape, which allowed the mushroom to adapt exceptionally well to its surroundings. providing excellent camouflage. Additionally, it was considered so valuable (because of its properties) that its locations were kept strictly secret by collectors. Today, the Maitake is known in both Asian and European-American regions as a delicious, meaty edible mushroom, distinguished by its high nutritional value. Because of this, it has garnered significant interest in the pharma industry, and has been a valuable research subject in Korean, Japanese and American studies for several years.
