Shiitake Extract Used in Asia as Cancer Medication
Tell Americans that a dish contains "mushrooms" and their minds automatically jump to button mushrooms (Agaricus bisporus), which have been grown commercially in the West since the 1600's. In contrast, individuals from Far East Asia are far more likely to jump to Shiitake as the most logical ingredient. Shiitake, which has only recently become a common household name in the West, has a long history of commercial cultivation in Asia.
Known alternately as Black Mushroom or Chinese Mushroom, wild Shiitake grows in Asia only. The name derives from the Shii Tree, its preferred host, although Shiitake may also grow on oaks and beeches. Shiitake has been cultivated in China and Japan for a thousand years.
Increasingly recognized in the West as a culinary mushroom, few westerners are yet aware of the medical applications of Shiitake. In Asia, it has a long tradition as a medicinal mushroom going back to the Ming Dynasty (AD 1368-1644) and the Chinese physician Wu Juei, who recommended it for conditions of the liver, respiratory and circulatory systems. Shiitake is also the most commonly studied mushroom in modern medical research, with special focus on its anti-tumor [94] and anti-viral properties. [93]
The preferred part of Shiitake to use medicinally is the mycelium (the "roots") because they contain compounds that either don't exist in the fruit body ("mushroom"), or are much more concentrated in the mycelium.
The most common extract is known as LEM, a protein extract from Lentinula Edodes Mycelia. (Lentinula edodes is Latin for Shiitake.) LEM has been shown to have powerful immune boosting properties, [95, 96, 97] particularly anti-bacterial. [98, 99] LEM has also been found to exhibit anti-cancer properties. [100] One study found it to kill melanoma cells while causing no harm to healthy cells. [101]
Lentinan is the name of another much researched compound isolated from Shiitake, named after the Latin genus name Lentinula. Lentinan is a polysaccharide that has been found to stimulate the human immune system to combat cancer. [102, 103, 104, 105, 106, 107, 108, 109, 110] It is currently used in Asia as an intravenous cancer drug.
Arabinoxylanes, compounds resulting from Shiitake-on-rice fermentation, have also demonstrated significant anti-viral activity. [111, 112, 113]
Two viruses in particular that have been studied with promising results are herpes simplex type 1 [114] and HIV [115, 116, 117]. It should be mentioned, however, that the previously mentioned Lentinan as an isolated compound does not appear to affect HIV replication. [25]
Additional studies have reported positive results with Shiitake extract in conditions of chronic fatigue syndrome [119] and Candida [118], as well as for septic shock prevention. [120]
In his book Mycelium Running, medicinal mushroom expert Paul Stamets also lists the following areas where research has shown Shiitake extract to have a beneficial effect: Blood Pressure; Blood Sugar; Cholesterol; Kidney Tonic; Liver Tonic; Sexual Potentiator; Stress; Breast Cancer; Liver Cancer; Prostate Cancer.
