Key Constituents
Principal immunomodulatory constituents, the main focus of anticancer-adjunct and immune research.
Bitter triterpenes associated with anti-inflammatory, hepatoprotective and adaptogenic activity.
The principal immunomodulatory polysaccharide, used clinically in Japan as an injectable cancer-adjuvant therapy.
A unique amino-acid-derived compound studied for cholesterol-lowering activity.

Safety, Cautions & Contraindications
Generally well tolerated at standard doses. May cause mild digestive upset, dry mouth, or dizziness in some individuals. May enhance the effects of anticoagulant and antihypertensive medications. Avoid during pregnancy and breastfeeding. Extended use beyond 6 months is not well studied in humans.
Duke (2002) rates reishi (Ganoderma lucidum) as + and notes immunostimulant, hepatoprotective, antioxidant, antitumor, and hypoglycemic activities at the experimental level (score 1). It is a key adaptogen in traditional Chinese medicine, valued for its polysaccharide (beta-glucan) content. Duke notes antiviral (score 1) and anti-aggregant activities. No strong clinical trials existed at time of publication, but lentinan and polysaccharide fractions from related species show immunomodulatory potential. Duke suggests caution in bleeding disorders due to anti-aggregant activity (Duke, 2002).
Generally very safe as a food. Raw or undercooked shiitake can cause a rare skin rash (shiitake dermatitis / flagellate dermatitis) in sensitive individuals — fully cooking eliminates this risk. May have mild anticoagulant effects. Rarely causes digestive upset. Well tolerated in normal culinary quantities.
Duke (2002) rates shiitake as +++ and notes immunostimulant, hypocholesterolemic, antibacterial, and anti-HIV activities at the experimental level (score 1). The key active compound is lentinan, a beta-1,3-glucan polysaccharide, which is used as an injectable anticancer drug in Japan. Duke notes clinical applications of shiitake preparations for immune support, cancer adjuvant therapy, and cholesterol management. Dose: 1–3 (606 mg) capsules up to three times daily for standardized preparations. Shiitake dermatitis (flagellate erythema) is a rare but recognized adverse effect from eating raw or undercooked shiitake — cooking prevents this (Duke, 2002).

Botanical Description
Bracket (shelf) fungus (not a true plant) that grows on the trunks and stumps of deciduous trees. It develops a hard, kidney- or fan-shaped cap with a glossy, varnished, red-brown to mahogany crust and concentric growth rings, often on a lateral woody stalk; the pale underside is covered in fine pores that release rusty-brown spores. The mycelium spreads through the wood substrate before fruiting.[1]
Wood-decay fungus (not a true plant) with a classic cap-and-stem mushroom form. The cap is broad, brown to dark brown, often with pale scale-like markings, with a fringed or curled margin when young; the underside bears numerous cream-coloured gills radiating from a central or slightly off-centre fibrous stem.
Habitat
Grows as a wood-decay fungus on the stumps and trunks of deciduous trees (notably maple and other hardwoods) in East Asian forests; also widely cultivated commercially on hardwood logs or sawdust substrate.
Grows naturally as a wood-decay fungus on fallen broadleaf trees (notably shii, oak and chestnut) in East Asian forests; almost all commercial shiitake today is cultivated on hardwood logs or sawdust blocks.
Harvesting
Wild fruiting bodies are collected once mature; cultivated material is harvested from logs or substrate at maturity, then dried and processed into slices, powder or extract.
Fruiting bodies are hand-picked once the cap has opened but before the margin fully flattens, then used fresh or dried; mycelium-based extracts are cultivated separately in liquid or grain culture.
Traditional Uses
Reishi/lingzhi, the 'mushroom of immortality', is one of the most revered tonic fungi in traditional Chinese medicine, used for centuries to support vitality, calm the spirit, strengthen immunity and promote longevity; this traditional tonic reputation is now studied for immunomodulatory, anticancer-adjunct and metabolic effects.[1, 4]
Shiitake has a very long East Asian culinary and medicinal tradition, used in Chinese and Japanese medicine as a tonic for vitality and longevity and to support healthy qi and blood; its polysaccharide lentinan, isolated from the fruiting body, has been used clinically in Japan as an adjunct immunotherapy, directly building on this traditional immune-tonic reputation.[11]
Preparations
Fruiting-body or mycelium extract standardised to polysaccharide (lentinan/beta-glucan) content, taken as capsules for immune support.
