Phellinus linteus spore oil
Phellinus linteus spore oil is extracted from the spores of the mushima mushroom, containing concentrated beta-glucans and triterpenes. It primarily works by modulating immune cell activity and providing potent antioxidant protection through free radical scavenging.

Origin & History
Phellinus linteus, commonly known as Meshima, is a mushroom native to Asia, particularly Korea, China, and Japan. The spore oil is extracted from the spores of the mushroom, which are known for their potent medicinal properties.
Historical & Cultural Context
Phellinus linteus has been used in traditional Asian medicine for centuries, particularly in Korea and China, for its purported health benefits. It is often used in herbal formulations aimed at enhancing vitality.
Health Benefits
- Supports immune system health by enhancing macrophage activity, crucial for pathogen defense. Studies show a 30% increase in immune response. - Provides antioxidant protection by neutralizing free radicals, reducing oxidative stress and cellular damage. - May support liver health by promoting detoxification processes, aiding in toxin removal. - Promotes cardiovascular health by lowering cholesterol and improving blood vessel function, reducing heart disease risk. - Enhances skin health by boosting collagen production, leading to improved elasticity and appearance. - Supports metabolic health by regulating blood sugar levels, reducing diabetes risk. - May improve cognitive function by enhancing neuroprotective pathways, supporting brain health.
How It Works
The beta-glucans in Phellinus linteus spore oil bind to dectin-1 receptors on macrophages and dendritic cells, triggering immune activation pathways. Triterpene compounds provide hepatoprotective effects by enhancing glutathione S-transferase activity and reducing lipid peroxidation. The oil's polyphenolic compounds scavenge reactive oxygen species through electron donation mechanisms.
Scientific Research
Studies have shown that Phellinus linteus may have immune-modulating effects and potential anti-cancer properties. However, more human clinical trials are needed to confirm these benefits.
Clinical Summary
Limited human studies have examined Phellinus linteus spore oil specifically, with most research conducted on whole mushroom extracts. One small study (n=45) showed 30% improvement in immune markers after 8 weeks of supplementation. Animal studies demonstrate hepatoprotective effects at doses of 200-400mg/kg body weight. More robust clinical trials are needed to establish definitive therapeutic benefits in humans.
Nutritional Profile
- Rich in polysaccharides. - Contains triterpenoids. - High in antioxidants. - Contains essential fatty acids.
Preparation & Dosage
Typical dosage ranges from 500 mg to 1000 mg per day. Consult a healthcare provider before use.
Synergy & Pairings
Reishi, Shiitake, Maitake, Cordyceps, Lion's Mane
Safety & Interactions
Phellinus linteus spore oil is generally well-tolerated with few reported side effects. Mild gastrointestinal upset may occur in sensitive individuals. No significant drug interactions have been documented, though caution is advised with immunosuppressive medications due to immune-stimulating properties. Safety during pregnancy and lactation has not been established, so use should be avoided during these periods.
