Turkey Tail (Trametes versicolor) is a colourful mushroom found on trees with many immune system boosting properties. It contains an impressive array of antioxidants, including phenols and flavonoids, that help inhibit or reduce damage caused by oxidative stress.*

Turkey tail contains two polysaccharopeptides, Krestin (PSK) and Polysaccharide Peptide (PSP), that possess powerful immune-boosting properties. They promote immune response by both activating and inhibiting specific types of immune cells and by suppressing inflammation.*

Keeping a healthy balance of beneficial bacteria in your gut is critical for maintaining a strong immune system. Turkey tail contains prebiotics, which help nourish these helpful bacteria supporting your immune system.*

Immune Boosting

Contains an impressive array of antioxidants, including phenols and flavonoids, that promote immune system health by reducing inflammation and stimulating the release of protective compounds.*

Gut Health

Healthy bacteria lives in our digestive system to support the 70% of our immune system that is located there. A stable microbiome supports our overall immune system. Imbalances in this microbiome or irritable bowel symptoms disrupt the fine balance of the immune system's role to eliminate pathogens and maintain healthy self-tissue.* 

The PSP in Turkey Tail has been studied for its impact on suppressing the growth of E. coli and Shigella bacteria strains. Turkey Tail contains prebiotics, which help nourish these helpful bacteria while suppressing problematic bacteria.*

Weight Management

The protein-bound beta-glucans (PBG) found in Turkey Tails has been studied as a potent anti-obesity component.*

Inhibited Cancer Cell Growth

Contains PSK, a polysaccharopeptide that actively inhibited the growth and spread of human colon cancer cells.*

"In Chinese medicine, we don't treat cancer. We treat the body," says Angela Tseng, DAOM, LAc, a core faculty member in Bastyr's School of Acupuncture and Oriental Medicine. "If the person's immune system is strong, they can cope with chemotherapy treatment better. We can help build their resistance to illness."
