Siberian Chaga Used in Russia as Cancer Drug
If you discover a black, cancerous mass on a birch, you may be looking at a Siberian chaga mushroom. It can also, less commonly, be found growing ash, beech, elm or hornbeam.
In Europe and Asia, chaga has been used for centuries to treat cancers of the heart and liver, digestive ailments, and tuberculosis. [121]
The traditional use was to peel the black skin of the mushroom and then boil it into a tea. Being a compact and easily portable medicinal made it very valuable to healers throughout history.
Modern research on chaga has mainly focused on its potential application as an anti-cancer remedy. In Russia, this usage was already approved as early as 1955 to treat lung, stomach, breast and cervical cancers. [122]
One modern study from 1998 showed that chaga extract did in fact inhibit growth of cervical cancer cell lines under lab conditions. [123] Another study from 1995 reported that an isolate of the active compound betulin first inhibited growth of melanoma cells in a lab, and then killed them. [124, 25]
Other research papers also confirm that some of the active compounds of chaga help retard the growth of cancer cells. [125, 126]
Although traditional healers used to peel off the black outside (probably because it looked unappetizing), the skin actually contains 30% betulin, a highly prized medicinal compound, [127] while the inside is rich in fungal lanostanes. So both parts would be valuable in preparing the tea.
Even better are chaga extracts that are made with not only the whole mushroom but also the mycelium, because the mycelium contains higher levels of medicinal proteins than the fruit body of the mushroom.
Other researchers have found chaga extract to be potently anti-viral. Two studies in 1996 found it to have an inhibitory effect on both influenza [127] and HIV. [128] Perhaps it does so by helping to stimulate the body’s natural immune functions, something that was first confirmed in 2002 and then again in 2005, [25, 129] and which may also help explain the historical use of chaga mushroom as an anti-inflammatory. [130]
Furthermore, alcohol extract of chaga mushroom has been found to lower blood sugar levels. [131] Chaga also demonstrates significant antioxidant properties that help protect the genetic integrity of the cells. [132, 133]
As an interesting aside unrelated to human health, a Quebec arborist uses a chaga poultice to cure chestnut blight. The trees later even become immune to the blight and resistant to future infections. [134]

Shiitake Extract Used in Asia as Cancer Medication
In America and Europe, the everyday “food mushroom” is the common button mushroom (Agaricus bisporus), commercially cultivated in France since the 1600’s. In the Far East, however, the likewise centuries old cultivation of gourmet mushrooms has been primarily focused on an entirely different species – the Shiitake. Only in the last few decades has Shiitake become a common household name in the West.
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.
What is less known in the West is that in the form of Shiitake extract, this is also the most studied medicinal mushroom of the Orient. The primary focus of research has been on the anti-viral [93] and anti-tumoral [94] properties.
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.
In fact, the most commonly researched Shiitake extract is known as Lentinula Edodes Mycelia extract, or LEM for short. (Lentinula edodes is the Latin name for Shiitake.) LEM has been reported in various research papers as being anti-bacterial, [98, 99] boosting the immune system, [95, 96, 97] and being anti-tumoral. [100] A study on melanoma found that it killed the mutated melanoma cells but caused no harm to cells that were healthy. [101]
Another active compound of Shiitake extract that has been much studied is Lentinan; a protein-free polysaccharide, so named after Lentinula, the Latin genus name for Shiitake. Lentinan does not directly kill tumors but has been shown to stimulate the tumor fighting mechanisms in the body of test subjects, [102, 103, 104, 105, 106, 107, 108, 109, 110] and is in fact in use in Asia as an injected cancer medication.
When rice is fermented with Shiitake mycelium, another group of medicinal compounds result. Known as arabinoxylanes, these compounds show great promise against viruses. [111, 112, 113]
Specifically herpes simplex virus type 1 [114] and more importantly HIV have responded to Shiitake extracts in several studies. [115, 116, 117] However, the previously mentioned Lentinan polysaccharide, by itself, has no significant effect on the replication of HIV. [25]
Other studies worth a brief mention have reported positive findings in the use of Shiitake extract to prevent septic shock, [120] and to treat Candida [118] and chronic fatigue syndrome. [119]
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.
