Forms of preparation
Simmer 3-9g in 3-4 cups water for 2 hours (hard, woody mushroom requires long extraction). Drink daily.
Traditional preparation, maximum extraction
Simmer in water 2 hours, then soak in alcohol 2 weeks. Combine both.
Extract both water and alcohol-soluble compounds
Take 1.5-9g powder in capsules or mixed in drinks.
Convenience
Steep extract powder in hot water. Add honey to taste.
Daily tonic
Approximate doses from the literature; they are not a prescription. Consult a professional.
Active compounds
Beta-glucans (polysaccharides) and ganoderic acids (triterpenes)
β-1,3/1,6-glucan polysaccharides · Immunomodulatory, antitumor, adaptogenic
Binding to Dectin-1 and TLR2 receptors, NK and macrophage activation, IFN-γ induction · 10-50% in hot water extract
Lanostanic triterpenes · Hepatoprotective, anti-inflammatory, histamine inhibitor, antitumor
HMG-CoA reductase inhibition, histamine release block, topoisomerase inhibition · 1-6% in standard sporocarp extract
Purine nucleosides · Antiplatelet, vasodilator, cardioprotective
Adenosine A1/A2 receptor agonism, cAMP phosphodiesterase inhibition · 0.01-0.05%
Heteropolysaccharides · Hypoglycemic
Stimulation of peripheral insulin secretion, inhibition of α-glucosidase · Fraction of total polysaccharides
Harvesting and processing
- Harvest
- Summer-autumn (July-October) when the carpophore is mature but before complete sporulation
It is harvested when the cap margin is no longer actively growing and begins to release spores. For maximum concentration of triterpenes, harvest before sporulation. The crop allows harvesting throughout the year.
Carpophore cut into thin slices of 2-5 mm, dried at 40-60°C until moisture content below 13%. The slices preserve the structure of the mushroom and allow authenticity to be verified.
Extraction with hot water and/or ethanol, then concentration and lyophilization. The extract standardized to 30% polysaccharides and/or 4% triterpenic acids is the most used in clinical research.
Spores collected at their peak release time, mechanically treated to break down the hard cell wall (chitinous wall) and increase triterpene absorption.
