Side Effects
When taken by mouth: Turkey tail mushroom is likely safe for most people. For most healthy adults, it is well-tolerated. Some people who are receiving chemotherapy and a substance extracted from turkey tail mushroom called polysaccharide krestin (PSK) have reported nausea, vomiting, low white blood cell counts, and liver problems.

Interactions
Moderate Interaction
Be cautious with this combination
Cyclophosphamide interacts with TURKEY TAIL MUSHROOM
PSP, a chemical found in turkey tail mushroom, might change how quickly cyclophosphamide is removed from the body. This might alter how effective it is, and cause more side effects.
Minor Interaction
Be watchful with this combination
Medications changed by the liver (Cytochrome P450 2C9 (CYP2C9) substrates) interacts with TURKEY TAIL MUSHROOM
Some medications are changed and broken down by the liver. PSP, a chemical found in turkey tail mushroom, might change how quickly the liver breaks down these medications. This could change the effects and side effects of these medications.
Dosing
Turkey tail mushroom contains polysaccharide krestin (PSK) and polysaccharide peptide (PSP). Some supplements contain just these chemicals, but the whole mushroom is also sometimes used. PSK has most often been used by adults in a dose of 3 grams by mouth daily for up to 36 months. Whole turkey tail mushroom has been used in a dose of 2.4 grams by mouth daily for up to 12 weeks. Speak with a healthcare provider to find out what type of product and dose might be best for a specific condition.
