Description
Lion's mane (Hericium erinaceus) is a whitish, bulbous tooth fungus in the Hericiaceae family (order Russulales). Instead of a cap it bears crowded, hanging spines 1-5 cm long that give it the look of a lion's mane or monkey head; the fruiting body reaches about 10-25 cm across. It grows as a weak parasite and saprotroph on hardwoods, especially beech and maple, across the temperate Holarctic, and is rare and threatened in much of Europe. In East Asia it has long been eaten as a choice edible (its texture and taste are likened to seafood) and used in traditional Chinese medicine. Modern research focuses on its neuroactive compounds, the hericenones and erinacines.
In traditional Chinese medicine the mushroom is used as a decoction or tonic; it is traditionally associated with supporting the stomach, digestion and general vitality.
Dried fruiting-body powder (e.g. as capsules/tablets) is taken to support cognitive function. A small randomized, double-blind, placebo-controlled trial (Mori et al. 2009) found improved cognitive-scale scores over 16 weeks in older adults with mild cognitive impairment; overall the clinical evidence remains limited.
In folk practice alcoholic extracts (tinctures) of the fruiting body are also used as a general restorative tonic.

Wild populations are rare and protected - do not forage; use cultivated material only. Allergic reactions (skin, respiratory) have been reported. Because of possible effects on blood sugar and clotting, consult a clinician before use if diabetic, taking anticoagulants, or pregnant/breastfeeding.
As an edible mushroom in ordinary food amounts there is no indication of a problem. For the concentrated extracts and capsules there are no studies in pregnant women at all — so do not use it as a supplement during pregnancy.
There are no data on passage into breast milk or on effects in breastfed infants.
Harmless as an edible mushroom provided it is cooked through. Extracts and capsules have not been studied in children.
Drug interactions
Gerinnungshemmer und Thrombozytenhemmer
In laboratory studies constituents of the mushroom inhibited platelet aggregation. Whether this matters in humans is unclear; caution is warranted with anticoagulant treatment and before surgery.
Blutzuckersenkende Mittel (Antidiabetika)
In animal studies the mushroom lowered blood sugar. With ongoing diabetes treatment and regular use of extracts, keep an eye on blood glucose.
Harvested part: fruiting body
- Time of day:
- Wild populations are highly endangered and protected in Germany — they are not gathered. From your own cultivation, harvest while the spines are pure white and no spores are dropping yet; yellowing or browning fruiting bodies taste bitter.
- Drying:
- Cut into slices about a centimetre thick and dry at 40 to 50 degrees until they snap. The mushroom is over ninety percent water and shrinks considerably.
- Storage:
- 12 months — Dried, keep airtight, dark and dry. Fresh, it keeps only three to five days in a paper bag in the fridge.
- Hericenones (A-H)Other
Aromatic compounds from the fruiting body; stimulate nerve growth factor (NGF) synthesis in vitro.
- Erinacines (A-K, P-S)Other
Cyathane diterpenoids, mainly in mycelium; potentially CNS-active (NGF promotion).
- Beta-Glucane / PolysaccharidePolysaccharide
Beta-glucans with immunomodulating properties.
- Phenolic acidsPhenolic acid
Phenolic acids with antioxidant activity.
- Ergosterol / SterolsOther
Fungal sterols (provitamin D precursor).
- Proteins and free amino acidsOther
High protein content (around 22% of dry weight) with numerous free amino acids.
