Most Americans think of mushrooms as ingredients in soup or intruders on a well-tended lawn. Stamets, however, cherishes a grander vision, one trumpeted in the subtitle of his 2005 book, Mycelium Running: How Mushrooms Can Help Save the World. Mushroom-producing fungi, he believes, can serve as game changers in fields as disparate as medicine, forestry, pesticides and pollution control. He has spent the past quarter-century preaching that gospel to anyone who will listen.
At the end of his TEDmed talk Paul Stammet shared that one day his mother came up to him and said her left breast was five times the size of the right one. Having never been to a doctor before she did not know what to do. After being told in hospital she may not have long to live, maybe three months to live, and the second worst account of breast cancer they have seen, and may need strong treatments, Paul went out on a wing and spoke to a doctor about his profession and showed him the literature, which the doctor allowed. After giving her some of the trametes versicolor over a year on top of the usual meds, she is now 100% cancer free a year later, the doctors said it was the quickest and most complete recovery they had ever witnesses.
It has been shown to have extremely potent anti cancer properties, but since it is not patentable the drug companies have never paid for the clinical trials it would need as a cancer treatment. The following scientific papers are all on the subject of its anti cancer properties:
