Ganoderma (Reishi) Mushroom: Nutrition & Benefits
Used as a decoction or extract, not eaten fresh: a wellness staple in East Asia.
Reishi (Ganoderma lucidum) is a woody bracket mushroom too tough to eat as food in the normal sense: it's traditionally simmered for hours into a tea or reduced into an extract. Old Chinese texts called it the "mushroom of immortality," and it remains one of the most recognisable names in East Asian wellness traditions.
It's grown on hardwood logs or sawdust blocks rather than compost, and because it's never eaten as a vegetable, its value sits entirely in the compounds extracted from it (mainly triterpenes and beta-glucans) rather than in conventional nutrition numbers.
