Also known as krestin, PSK is one of the most well-studied compounds in turkey tail mushrooms. It has been used as an adjuvant in cancer therapy, particularly in Japan, to boost the immune system and help fight cancer cells.
Polysaccharide-Peptide (PSP):
Similar to PSK, PSP is another potent polysaccharide found in turkey tail mushrooms that has immune-boosting and potential anticancer properties.
Beta-Glucans:
These are a form of polysaccharides that play a significant role in immune system enhancement and have been shown to activate immune cells like macrophages and natural killer cells.
Triterpenoids:
Although less prominent than in other medicinal mushrooms, turkey tail contains triterpenoids, which have anti-inflammatory and anticancer effects.
Phenolic Compounds:
Turkey tail mushrooms are rich in antioxidants, including phenolic compounds that protect against cellular damage and reduce inflammation.
Quercetin:
This flavonoid, found in turkey tail mushrooms, has antioxidant and anti-inflammatory properties, further contributing to the mushroom’s medicinal benefits.
Notable Benefits:
Immune Stimulator
Turkey tail is primarily known for its remarkable immune-boosting properties, largely due to its rich content of polysaccharides:
Polysaccharide-K (PSK):
This compound has been extensively studied and used as an adjunct cancer therapy, particularly in Japan, for its ability to stimulate the immune system, enhancing the activity of natural killer cells, dendritic cells, and other immune cells.
Polysaccharide-peptide (PSP):
Similar to PSK, PSP also boosts the immune system by activating immune cells and stimulating the production of cytokines, helping the body to fight off infections and diseases more effectively.
Prebiotic
Turkey tail mushrooms support gut health through their prebiotic properties:
Dietary fiber:
The high fiber content in Turkey tail, especially in the form of polysaccharides like beta-glucans, feeds beneficial gut bacteria, promoting a healthy gut microbiome. This can lead to improved digestion, nutrient absorption, and overall immune health.
Anti-Viral
Turkey tail has shown promising antiviral capabilities against various viral infections:
Direct antiviral effects:
Compounds in Turkey tail, including PSK and PSP, have demonstrated the ability to inhibit viral replication and boost the body’s antiviral immunity.
Immune-mediated antiviral activity:
By enhancing the immune response, Turkey tail can help the body more effectively combat viral pathogens and reduce the severity of viral infections.
