Siberian chaga mushroom appears as a black mass on birch trees, dead or alive. Occasionally, it may also be seen growing on hornbeam, ash, elm or beech.
In Europe and Asia, chaga has been used for centuries to treat cancers of the heart and liver, digestive ailments, and tuberculosis. [121]
The black “skin” was removed and the lighter inside boiled as tea. Being such a compact natural medicine made it a valuable, portable remedy for healers of old.
Today’s scientific focus on chaga extract is primarily as an anti-tumor remedy. In fact, it was approved in Russia as a cancer drug already in 1955, successfully used to treat cancers of the stomach, lungs, breasts and cervix. [122]
A 1998 study on chaga extract showed that it did inhibit growth of cervical cancer in a lab. [123] And a 1995 study reported both growth inhibition and death of melanoma cells, also in a lab (in vitro). [124, 25]
Additional research has shown cancer cell division to be decreased by some of the active compounds of the chaga mushroom. [125, 126]
The black color of chaga is caused by betulin, a medicinally active compound that makes up 30% of the skin. [127] The lighter inside of the mushroom is rich in fungal lanostanes. So chaga tea may be more effective if made with the whole mushroom, including the skin.
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 research has found chaga to possess powerful anti-viral properties. In 1996, two studies published results of inhibitory effects on both influenza virus [127] and HIV. [128] Considering the nature of viruses, the most likely scenario is that chaga works on viruses by enhancing the body’s own immune system, a theory confirmed by a paper published in 2002 and another in 2005. [25, 129] The same mechanism may explain the reported anti-inflammatory effect of chaga. [130]
Alcohol extract of Siberian chaga has been shown to help balance blood sugar. [131] It is also a powerful antioxidant. [132, 133]
As an amusing aside not related to human health, Siberian chaga may even be used as a tree medicine. Paul Stamets relates a story of a Quebec arborist using a chaga poultice to heal chestnut blight. Not only does it cure the tree, but the tree even becomes resistant to further infections of blight after having been treated. [134]
