Questions and Answers About Turkey Tail and Polysaccharide-K (PSK)

  1. What is turkey tail?
    Turkey tail is a type of mushroom that grows on dead logs worldwide. It's named turkey tail because its rings of brown and tan look like the tail feathers of a turkey. Its  name is Trametes versicolor or Coriolus versicolor. In , it is known as Yun Zhi. In Japan, it is known as kawaratake (roof tile ). There are many other types of Trametes mushrooms. It can be hard to tell the difference between turkey tail and other types of Trametes mushrooms without the use of special testing.
    Turkey tail has been used in traditional Chinese medicine to treat  diseases for many years. In Japan, turkey tail has been used to strengthen the  when given with   treatment.
  2. What is PSK?
     K (PSK) is the best known active  in turkey tail mushrooms. In Japan, PSK is an approved mushroom product used to treat cancer.
  3. How is PSK given or taken?
    PSK can be taken as a tea or in  form.
  4. Have any laboratory or animal studies been done using PSK?
    In ,   are used to test a substance to find out if it is likely to have any anticancer effects. In , tests are done to see if a , procedure, or treatment is safe and effective in animals. Laboratory and animal studies are done before a substance is tested in people.
    Laboratory and animal studies have tested the effects of PSK on the immune system, including immune cells called  and . For more information on laboratory and animal studies done using PSK, see the Laboratory/Animal/Preclinical Studies section of the health professional version of Medicinal Mushrooms.
  5. Have any studies of PSK been done in people?
    PSK has been studied in patients with , , , and . It has been used as  in thousands of cancer patients since the mid-1970s. PSK has been safely used in people for a long time in Japan and few  have been reported.

This excert tells us a lot about the science and history of Turkey Tail mushrooms and gives us a glimpse into the thesis of the science being reported. 

Outlining the affects of Polysaccharide-K in cancer treatment, the article continues by addressing specifically gastric, breast and lung cancers.

Gastric cancer
Studies show that the use of PSK as adjuvant therapy in patients with  (stomach) cancer may help repair immune cell damage caused by  and strengthen the immune system.
Studies of PSK as adjuvant therapy for gastric cancer include the following:
  • A  in Japan done between 1978 and 1981 included 751 patients who had  for gastric cancer. After surgery, patients received chemotherapy with or without PSK. On average, the patients who received chemotherapy and PSK lived longer than those who received chemotherapy alone. The researchers believe it might be possible to predict which patients would benefit the most from PSK depending on the numbers of  and  in the patient’s .
  • In 1994, a study in Japan followed 262 patients who had successful surgery for gastric cancer and were given chemotherapy with or without PSK. Patients who received chemotherapy and PSK were less likely to have  and lived longer than those who did not. Treatment with PSK caused few side effects. The researchers thought the study showed that PSK and chemotherapy should be given to gastric cancer patients after surgery to remove the cancer.
  • A review published in 2007 combined results from 8 randomized  in 8,009 patients who had surgery to remove gastric cancers. After surgery, patients in the trials were given chemotherapy with or without PSK. The results suggest that receiving chemotherapy and PSK helped patients live longer after surgery.
Breast cancer
To date, PSK studies in patients with breast cancer have focused on changes in the immune system (T-cell and  levels in the blood) rather than on  results (patient survival, , side effects, and ).
Colorectal cancer
Studies of PSK as adjuvant therapy for colorectal cancer include the following:
  • PSK was studied in a randomized clinical trial for its effect on the immune system in patients with  or . Patients received chemotherapy and radiation therapy, with or without PSK. This study found that PSK increased the number of cancer-killing immune cells and had anticancer effects in  that received radiation therapy.
  • A review that combined results from 3 studies in 1,094 patients with colorectal cancer found that patients who received PSK were less likely to have recurrent cancer and lived longer than those who did not.
Lung cancer
Studies of PSK as adjuvant therapy for patients with lung cancer include the following:
  • Five  reported that patients treated with PSK and radiation therapy with or without chemotherapy lived longer.
  • Six randomized clinical trials in patients with lung cancer studied chemotherapy with or without PSK. The studies showed that patients who received PSK improved in one or more ways, including , body weight, well-being, tumor-related symptoms, or longer survival.

The article gives us an idea of the impact of the benefits of Turkey Tail and mentions that there have been few reported side affects throughout the available literature on polysaccharide-K.

 

Though this publication is new, the science is thorough, extensive and draws from several sources to provide its conclusions. We are able to draw conclusions about the incredible nature of Turkey Tail and it's capacity to help the lives of those affected by cancer and other ailments.
