Key Points
- The turkey tail mushroom, a well-documented medicinal mushroom, grows on dead logs and can be found throughout North America as well as many other regions of the world.
- Although turkey tail mushrooms are not poisonous, they are not typically consumed as a food.
- BCCT considers turkey tail mushroom extracts and supplements interesting and promising because of mounting scientific evidence of their usefulness as an adjuvant treatment in several cancers, their safety when taken appropriately, their wide availability and their use by many reputable integrative oncology clinicians.
- Side effects, typically mild and temporary, have been seen in animal studies and in an early clinical trial. A few cautions are noted.
- Extracts of turkey tail are widely available without prescription in capsule, liquid tincture, and powdered form. Strength and purity of products can vary significantly.

The turkey tail mushroom, in use in traditional Chinese medicine for many years, is one of the most intensively studied globally. A formulation called PSK or Krestin™ has been studied and used extensively in Japan for its immune-modulating effects and also as a cancer adjuvant (supplement) treatment. Use of PSK in thousands of cancer patients in Japan since the 1970s has established this mushroom’s safety record.

The known active constituents of turkey tail mushrooms associated with its medicinal properties:
- β-glucans
- PSK (protein bound polysaccharide, β (1-4)D-glucan protein): Krestin (Japanese formulation)
- PSP (polysaccharopeptide)
- Ergosterol (provitamin D2 derivatives)
Turkey tail is prepared from three forms:
- Fruiting bodies (the part that grows above ground or outside the host tree)
- Mycelium (the thread-like, root-like branching hyphae) grown on grain
- Mycelium in fermentation
Treating the Cancer
Working against cancer growth or spread, improving survival, or working with other treatments or therapies to improve their anticancer action
Documented medicinal properties of turkey tail include immune enhancement and antitumor, antiviral, antibacterial and antioxidant activities.
Neither the turkey tail mushroom nor its constituents have been proven to be a cure for cancer as a single agent. The evidence suggests that its greatest benefit is found when used in conjunction with evidence-based conventional treatment. After conventional treatment is complete, turkey tail may be used (particularly in combination with other medicinal mushrooms) as part of an integrative plan to restore health and prevent recurrence.
Clinical Studies
Phase I, II and III randomized clinical trials of turkey tail mushroom have been conducted in the following cancers:
- Breast
- Colorectal
- Esophageal
- Stomach
The US Food and Drug Administration (FDA) has approved a few clinical trials of this mushroom combined with chemotherapy for several different cancers, although to date only one study has been completed.
Turkey tail has shown these effects, which BCCT regards as strong:
Expand list
- Enhancing chemotherapy and radiotherapy effects on cancer cells while protecting normal cells
- Improving survival by enhancing the host immune system against tumor cells
- Improving five-year survival in patients with lung cancer stages I-III
- Inhibiting the activity of suppressor T-cells in the regional lymph nodes in people with gastrointestinal cancer. Suppressor T-cells prevent the immune system from recognizing and responding to the cancer.
- Improving both the five-year disease-free rate and five-year survival after curative gastrectomy
- Extending survival in a group of patients with high granulocyte and lymphocyte count ratios, perhaps through restoration of immunocompetence
- Extending survival in patients with certain types of breast cancer
- Improving the survival curve of people with operable breast cancer with vascular invasion
PSP effects:
- Slowing deterioration in patients with non-small cell lung cancer
- Not all study results have been positive. According to the About Herbs summary on turkey tail, some “studies on breast cancer, hepatocellular carcinoma, and leukemia produced mixed results. A hot water extract of Coriolus, VPS, was found to enhance development of large intestinal tumors in mice.”
Lab and Animal Studies
Read more
Lab and animal evidence indicates that turkey tail has either direct or indirect anticancer effects in the following cancers:
- Breast
- Cervical/uterine
- Colorectal
- Esophageal
- Gastric
- Leukemia
- Liver
- Lung
- Melanoma
- Nasopharynx
- Prostate
- Sarcoma
- Some studies show evidence of effect for cancers in general.
A methanol extract of T. versicolor inhibited the growth of six various solid tumors from four cancer types:
PSK (a glycoprotein-bound mixture) is the best-known component of turkey tail. While its mechanism of action is not yet clearly defined, studies of PSK suggest the following anticancer mechanisms:
- Direct anticancer effects resulting in reduced tumor growth and metastasis
- Enhancing the effectiveness of chemotherapy and radiation therapy against cancer cells while protecting normal cells
PSP is less known, but also has medicinal properties. PSP extracts from turkey tail mushroom in preclinical studies have significant immune and anticancer activity:
- Influence (modulate) gene expression: decreases a gene master switch that turns on genes that drive cancer transformation, development and progression) and also decreases COX-2 expression. which is associated with chronic inflammation, a contributor to cancer development
- Influence (modulate) immune response by activating cancer cell-killing macrophages, helper T cells and natural killer cells
- Control the intestinal microbiome and interplay with host cells as a prebiotic
- Chemopreventive effects through elimination of prostate cancer stem cells
Cautions
When used appropriately, both oral turkey tail mushroom and PSK and PSP extracts of turkey tail have appeared safe when used in daily doses for extended periods. Studies of turkey tail in cancer commonly cite doses of three grams per day, though a Phase I clinical trial in breast cancer cites safety with doses up to nine grams per day for six weeks.

In one report, three cases of toxicity were noted, and PSK use was discontinued. Liver impairment and low white blood cell counts have been reported in clinical trials.
The US FDA doesn’t provide strict regulation of herbs and supplements, including medicinal mushrooms. Therefore, strength, purity or safety of individual products are not guaranteed. Read product labels carefully. If you have a medical condition, or if you are taking other drugs, herbs or supplements, consult with a healthcare professional, preferably one with expertise in prescribing medicinal mushrooms such as a traditional Chinese medicin (TCM) practitioner, naturopathic oncologist or integrative medicine physician, before taking medicinal mushrooms. Consult a healthcare professional immediately if you experience side effects.
Side Effects
A low incidence of side effects, typically mild and temporary, has been seen in an early clinical trial and in animal studies. Limited gastrointestinal upset has been reported. Some report a cough and temporary darkening of the fingernails with taking the powdered drug. Passing dark-colored stools (not due to blood in stools) has also been reported. Medical supervision is advised, preferably from a licensed clinician with experience in prescribing medicinal mushrooms.

The interactions of turkey tail or its components with other medications, herbs, supplements, foods, lab tests or diseases have not been established. In some human studies, people receiving both chemotherapy and PSK have experienced nausea, low white blood cell counts and liver problems. Reduced liver function could impact the metabolism of other supplements, drugs and substances that are broken down by the liver, possibly increasing their side effects.
Contraindications/Do Not Use
Do not take turkey tail or its extracts if you have a known allergy/hypersensitivity to turkey tail, PSK, or any of its components. There is insufficient evidence to establish safety of use during pregnancy and lactation. Mushroom extracts are not recommended during pregnancy.
Preparation
Note that in traditional Chinese medicine and in many of the studies of medicinal mushrooms, hot water extracts have been used. The cell wall of the mushroom is indigestible by humans—hence, eating raw mushrooms for culinary or medicinal reasons is not recommended. Ground mushroom eaten as a powder is irritating to the liver, yet when that ground mushroom is decocted in hot water, the medicinal ingredients become available and it is safer to consume. As a result, several integrative oncology clinicians report that they prescribe hot water extracts of medicinal mushrooms.
Integrative oncologist Keith Block, MD, advises using extracts (rather than eating whole mushrooms) that are blends of several different medicinal mushrooms, including turkey tail. (See Commentary below).
Access
Extracts of Turkey Tail are widely available without prescription in capsule, liquid tincture and powdered form. Strength and purity of products can vary significantly. Read labels carefully. Consult with a healthcare professional experienced in using medicinal mushrooms for guidance in product selection.
Dosing
BCCT does not recommend therapies or doses, but only provides information for patients and providers to consider as part of a complete treatment plan. Patients should discuss therapies with their physicians, as contraindications, interactions and side effects must be evaluated. Levels of active ingredients of natural products can vary widely between and even within products. See Quality and Sources of Herbs, Supplements and Other Natural Products.

In a 2008 article, Standish et al. suggest that “immune therapy utilizing the polysaccharide constituents of Trametes versicolor (Tv) as concurrent adjuvant cancer therapy may be warranted as part of a comprehensive cancer treatment and secondary prevention strategy.”
In Life Over Cancer, Dr. Keith Block advises: “It is difficult to obtain clinically meaningful quantities of the mushroom phytochemicals from even the healthiest diet, which is why I recommend getting them in the form of extracts. Look for those containing maitake (Grifola frondosa), agaricus (Agaricus blazei), shiitake (Lentinula or Lentinus edodes), reishi (Ganoderma lusidum), turkey tails (Trametes or Coriolus versicolor), and caterpillar fungus or cordyceps (Cordyceps sinensis).”
Paul Stamets, in MycoMedicinals, says this about using a blend of several different medicinal mushrooms: “A number of researchers have come to the conclusion that, to maximize a host-mediated response—that is, to awaken the immune system---a panoply of polysaccharides and medicinal mushroom constituents is best. These constituents increase the number and activity of macrophages, killer T and NK lymphocytes. Combining medicinal mushroom species sends the immune system multiple stimuli, awakening the body’s natural defenses.”
Lise Alschuler, ND, FABNO, August 9, 2018: There are instances when I use specific mushrooms, for instance: Coriolus (aka Trametes) versicolor (turkey tail) for breast cancer, Agaricus blazeii for ovarian cancer and chaga mushroom for melanoma. However, it is a very valuable and reasonable strategy to use a blend that includes mushrooms, each of which is standardized to its polysaccharides and beta-glucans. The key is to use a hot water extract of the fruiting bodies or a full-spectrum extract (includes mycelium) that clearly identifies on its label the quantity of mushroom extract.

Some blends that I often recommend are:
Per capsule:
- Trametes versicolor (turkey tail) (40% polysaccharides, 40% beta-glucans) - 100mg
- Grifola frondosa (maitake) 40% polysaccharides, 30% beta-glucans - 100mg
- Ganoderma lucidum (reishi), 40% polysaccharides, 15% beta-glucans - 100mg
- Lentinula edodes (shiitake), 409% polysaccharides, 40% beta-glucans - 100mg
I would recommend between 2-3 capsules twice daily.
When recommending single mushrooms, it is important to know how much beta-glucan is in each serving so that I can titrate my dose accordingly. For instance, I often use Grifola frondosa m(aitake) mushroom to increase white blood cell counts. One product I use contains:
Per 6 tablets:
- Maitake (Grifola frondosa) Fruiting body powder - 600mg
- Maitake fruiting body extract, standardized to contain 30% D-fraction - 240mg (so 72mg D-fraction beta glucan)
- Vitamin C 120mg (supports bioactivity)
Cost-permitting, in most clinical studies, the daily dose of mushroom extracts that is correlated with improved survival (especially in breast, colorectal, gastric cancers) is 3000mg/day.
Mushrooms do pack a punch! From a meta-analysis on Coriolus versicolor mushroom extracts in patients diagnosed with cancer:
- Over all cancers, there was a 9% absolute reduction in 5-year mortality (one additional patient alive for every 11 pts treated).
- Effects were more evident for breast, gastric or colorectal cancer versus esophageal or nasopharyngeal
