MycoIMMUNE - Research
Long used in Chinese medicine for “immortality and longevity”, Reishi has been shown to increase plasma antioxidant capacity, promoting longevity by facilitating protection of cellular DNA. [1,2,3]
Reishi has also enhanced immune response in cancer patients, shown promise as a cancer-arresting compound and further trials are underway. [4,5]
In 2011-2012, the NIH founded a $5.4 Million study at Bastyr University that proved Turkey Tail effectively fights breast cancer  and Turkey Tail mushrooms have even been approved by the FDA as an adjunctive anti-cancer treatments for both Prostate and Breast cancers.
Turkey Tail contains a compound known as “Polysaccharide K” or PSK that has been shown to Polysaccharide K and Coriolus versicolor extracts for lung cancer: a systematic review.  Larger studies are underway to continue to explore the potential of this powerful natural healer.
Other studies reinforcing the immuno-modulating capabilities of Turkey Tail, verifying that PSK “may act to increase leukocyte activation and response through up-regulation of key cytokines. Indeed, natural killer (NK) and lymphocyte-activated killer (LAK) cell activation has been demonstrated in vivo and in vitro, and recent genetic studies reveal increased expression of key immune cytokines in response to treatment with PSK.” 
In yet another study, “protein-bound polysaccharide K (PSK) increased the 5-year disease-free survival rate and reduced the risk of recurrence in a randomised, controlled study for stage II and III colorectal cancer.” 
As reported in this review, numerous recent studies have verified the anti-inflammatory and anti-cancer properties of medicinal mushrooms, including Chaga.  There are also numerous reports of anti-bacterial and anti-viral properties attributed to medicinal mushrooms, including Chaga, which has been used for centuries in Russian teas and tonics. 
Specifically, Chaga has been shown to selectively kill cancer cells without harming human cells. “These data indicate that Chaga extract has selective cytotoxic effects on human hepatoma cells. This selectivity may be the great advantage of the Chaga extract for therapeutic or preventative use in cancer treatment.” 
Chaga can be used to improved digestive disorders by lowering inflammatory cytokines associated with certain gastrointestinal maladies.
