Turkey Tail is a medicinal mushroom. It is also known as Trametes versicolor or Coriolus versicolor, and Yun Zhi in traditional Chinese medicine. Commercial extracts of Coriolus include polysaccharide peptides (PSPs) or polysaccharide K (PSK). Beyond eating the mushroom, it can be found in a powder, capsule, tincture form. It is best as water extract as it contains a higher content of the beneficial phenolic compounds. (1)
Turkey tail is most commonly used in cancer care to help stimulate the immune system, directly inhibit growth of cancer cells and slow progression of disease as well as overall improve quality of life by reducing side effects of conventional treatments and cancer-related symptoms. (2-9)
PSP has been found to increase expression of cytokines and chemokines, active natural kill (NK) cells and enhance dendritic and T-cell infiltration in tumors. (2) There has been ongoing research showing that turkey tail may enhance immune function (lymphocytes and NK cells) in breast cancer undergoing radiation. (3) In colorectal cancer patients, it may be useful to improve quality of life in terms of mitigating side of chemotherapy. (4,5) It may also lead to an increase in disease-free survival when used alongside standard chemotherapy in colorectal cancer. (6,7) In patients with liver cancer, when Coriolus was used alongside conventional treatments had improved cognition, social, and emotional functioning in addition to nausea, vomiting, pain, insomnia, constipation, diarrhea. (7,8) Interestingly, there has been some evidence for the use of vaginal gel including Coriolus to enhance HPV clearance in low-grade cervical lesions. (10)
