Lions mane

Hericium erinaceus
Family: Hericiaceae  ·  Parts used: Fruiting body, Mycelium  ·  Also known as: Lauvas krēpes

The complete database record: 2 documented constituents, 5 pharmacological actions, 10 traditional / indicated uses, with 15 cited sources.

Botanical Description

Wood-decay fungus (not a true plant) forming a distinctive rounded, cushion-like fruiting body covered in long, dangling, tooth-like spines rather than gills or pores, resembling a white or cream 'lion's mane' or icicle cluster. It grows as a single mass rather than a typical cap-and-stem mushroom, on wounds or dead wood of hardwood trees.

Height: Fruiting body 5-40 cm across
Habit: Wood-decay fungus forming a rounded, spine-covered fruiting body
Leaves: Not applicable (fungus)
Flowers: Not applicable (fungus); reproduces by spores
Stem: No true cap-and-stem structure; a single cushion-like mass of hanging spines
Root: Mycelium spreading through the wood substrate
Fruit: Long, dangling, tooth-like spines bearing the spore-producing surface
Flowering Period: Fruiting body develops over weeks on wounds or dead hardwood

Habitat & Distribution

Grows on wounds, dead or dying wood of hardwood trees (notably oak and beech) in temperate forests of the Northern Hemisphere; also widely cultivated commercially on hardwood logs or sawdust substrate.

Harvesting

Wild fruiting bodies are collected once mature; cultivated material is harvested from logs or substrate at maturity, then used fresh, dried, or processed into mycelium-based supplements.

Parts: Fruit, Mycelium

Key Constituents

Erinacines and hericenones[1, 3, 5]

Diterpenoid erinacines (concentrated in the mycelium) and aromatic hericenones (in the fruiting body) are the signature low-molecular-weight compounds that stimulate nerve growth factor synthesis and underlie the mushroom's neurotrophic and neuroprotective effects.

Polysaccharides (beta-glucans)[4, 6, 7]

High-molecular-weight fruiting-body and mycelial polysaccharides with immunomodulatory, anti-inflammatory and prebiotic activity - alleviating ulcerative colitis, activating macrophages and supporting gut microbiota.

Traditional Use & History

Lion's mane has a long East Asian culinary and medicinal tradition, valued in Chinese and Japanese medicine as a digestive tonic and, more recently, intensively studied for its unique ability to stimulate nerve growth factor, giving it a modern reputation as a neurotrophic and cognitive-support mushroom.[1]

Preparations

Standardised extract[1]

Fruiting-body or mycelium extract standardised to erinacine or hericenone content, taken as capsules or powder; the form used in most clinical cognitive-support studies.

Dosage

Standardised extract[3]

A 49-week double-blind randomised trial in mild Alzheimer's disease used three erinacine A-enriched H. erinaceus mycelia capsules per day at 350 mg per capsule, i.e. 1050 mg daily. Other clinical studies of cognitive support commonly use around 1-3 g of dried fruiting body extract daily. Educational reference only, not a prescription.

Safety, Cautions & Contraindications

Safety note[9, 10, 11]Caution

Mild gastrointestinal upset (nausea, bloating, diarrhoea) is the most common side effect. Rare allergic reactions can occur, particularly in individuals sensitive to mushrooms, and it may slightly lower blood sugar or have mild blood-thinning effects, so caution is advised for people on diabetes or anticoagulant medications.

Safety note[9, 10, 11, 15]Info

Duke (2002) does not include a dedicated entry for Lion's mane mushroom (Hericium erinaceus) in the Handbook of Medicinal Herbs, Second Edition.

Harvest Readiness

[8]

Part: fruiting-body
Signals: Harvest when the fruiting body has stopped growing and the spines are long and still white - before they turn yellow or brown.
Basis: traditional
Source Quote: Lion's mane mushrooms are done growing when they stop increasing in size and the spines grow longer and thicker.
Species Confirmed: 1
Notes: GroCycle (REF-3270) for Hericium erinaceus; harvest when growth stops and the spines are long, before they yellow/brown ('harvest them before they turn yellow or brown for the best flavor and texture'). Single source -> provisional.
