Key Benefits
FDA Orphan Drug
Lentinan holds FDA Orphan Drug status — administered IV in Japanese hospitals alongside chemotherapy for gastric cancer
Cholesterol Reduction
Eritadenine uniquely inhibits dietary cholesterol conversion — 15–25% reduction in total cholesterol in 7-day clinical trials
Cancer Adjunct (AHCC)
AHCC from Shiitake mycelium significantly improves NK cell activity vs. placebo in published oncology RCTs
Antiviral Compounds
Lentinan and lenthionine demonstrate activity against HIV, hepatitis B, and influenza in controlled laboratory studies
The umami king — cultivated for over 1,000 years in East Asia and the only edible mushroom with an FDA Orphan Drug designation (lentinan, for cancer immunotherapy). Lentinula edodes also contains eritadenine (lowers LDL cholesterol) and AHCC — a compound used in Japanese hospitals alongside chemotherapy.
Culture Bank — 10cc of lab-isolated mycelium in nutrient broth, selected for thick caps, dense gills, and the rich smoky flavor profile chefs demand. Colonizes grain in 5–10 days. Two paths from here: sawdust blocks yield first pins in 8–12 weeks; oak logs colonize over 6–12 months and then produce perennial flushes for 3–5 years with dramatically superior flavor and texture.
Pro tip: trigger fruiting with a cold-shock soak (50°F water for 12–24 hours) once substrate is fully colonized.
