Siberian Chaga Used in Russia as Cancer Drug
Posted by Dr. Markho Rafael | Under Disease & Illness Thursday Feb 4, 2010Siberian 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.
Europeans have used chaga for centuries as a cure for digestive ailments, tuberculosis, and cancers of the liver and heart. [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 modern study conducted in 1998 showed that chaga extract does indeed inhibit the growth of cervical cancer cells under laboratory conditions. [123] Another study from the mid-90’s found the active compound betulin to cause growth inhibition and death of melanoma cells, also in lab. [124, 25]
Additional research has shown cancer cell division to be decreased by some of the active compounds of the chaga mushroom. [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 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]
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]
