What is Shiitake?

Shiitake is a well-known mushroom popular for its culinary delight. However, what may be less known are Shiitake’s extraordinary health benefits. Apart from being delicious, these ‘miracle mushrooms’ boost immunity, lower cholesterol, and increase bone density as they contain a high quantity of vitamin D. The Shiitake mushroom is one of the most versatile and popular mushrooms worldwide, due to its taste, easy cultivation, and various health benefits. Growing in the Far East, Korea, Japan, and China, Shiitake’s mycelia and fruiting bodies can be found on decaying wood and have been used for at least 1,000 years as an edible mushroom. They are currently the second most cultivated mushroom, following the common white button mushroom.
Types of Shiitake

There are many variations of Shiitake; for example, Donko, Tenpaku Donko, and Chabana Donko, which vary in taste and size. The Tenpaku Donko Shiitake mushroom is largely considered the highest quality variation; however, the healing properties of different varieties remain consistent regardless of the type of Shiitake as these are mostly differentiated by taste.

Shiitake: the Miracle Mushroom
Shiitake derives its name from the Japanese word ‘Shii’ and ‘take’, referring to the name of the tree where the mushroom is mostly found, the Castanopsis cuspidate, (Shii) and the word for mushroom (take). Likewise, Shiitake’s Latin name, Leninula edodes, is just as modest meaning edible or aromatic mushroom. The label ‘miracle mushroom’, however, refers to Shiitake’s encredible immune boosting properties, having been used for centuries to combat viral infections, microbial imbalances, and protecting against influenza.

Shiitake is a powerful medicinal mushroom as studies have highlighted the variety of vitamins (including high amounts of vitamin D) contained within the fungus. An incredible bone and joint health aid, Shiitake is known to reduce joint pain and the symptoms of gout over prolonged use. In addition, this fungus is, in fact, a powerful anti-fungal, known to treat and reduce the symptoms of fungal infections, such as candida.

The benefits of Shiitake are derived from polysaccharide lentinan, which seems to boost the body’s immune response, increasing immunity, longevity, blood circulation, and liver health. Multiple studies have identified lentinan as an effective treatment of cancer and, as such, has been used in conventional oncology therapies. These studies observed Lentinan having significant effects on the reduction of cancerous tumours, elimination of cancer cells, and the restoration of chromosomes damaged by cancer cells. In Asia, the results of various clinical trials showed significant increases in the life expectancy of patients when chemotherapy was used in conjunction with lentinan. This indicates that lentinan potentially relieves the negative side-effects of chemotherapy; improving not only patient longevity, but also quality of life.

Likewise, the other major healing compounds residing in the Lentinula Edodes Mycelium (LEM), including lentin, lanthionine, and lentinosin, protect against cell damage and boost the production of white blood cells, working as an antibiotic. All major healing compounds found in the LEM increase bone marrow cell formation; these cells are the building blocks of the body’s immune system. Shiitake also naturally contains large quantities of copper, which helps in the creation of red blood cells, supporting healthy blood vessels and bones. As Shiitake aids bone health, it can relieve osteopenia and osteoporosis-like symptoms due to its ability to produce vitamin D from sunlight. In addition to bone related conditions, Shiitake can relieve the effects of viral infections, such as HIV, by preventing cell damage and the proliferation of viral cells.

Shiitake’s immune boosting qualities are not only due to its polysaccharides but also to its large quantities of vital nutrients. Containing vitamin B2, B6 and B12 Shiitake is a good substitute for animal protein, making it an excellent superfood for vegans and vegetarians. Shiitake also contains a lot of potassium, which balances the cardiovascular system by releasing sodium from the kidneys, maintaining healthy blood pressure levels. Additionally, 33% of the recommended daily intake of vitamin B5 is contained within 4 dried Shiitake mushrooms. Vitamin B5 helps lower cholesterol and the body’s ability to produce energy from fats. These vital nutrients are but a fraction of what is contained within the Shiitake mushroom, as also it contains high quantities of Phosphorus, Magnesium, Iron, Zinc, Riboflavin, and Selenium, to name a few.
