    Lion's Mane

    Hericium erinaceus

    Functional mushroom

    The shaggy white 'smart mushroom' that grows in cascading spines on hardwood trees.

    Traditional use

    Prized in East Asian herbal practice for centuries, Lion's Mane tea was reputedly brewed by Buddhist monks to support concentration during long meditation. In Japan it's known as Yamabushitake, after the mountain monks who sought it out.

    Provenance, where ours comes from

    Organically cultivated on natural hardwood substrate with fresh air and sunlight, conditions that mimic the wild, then extracted from 100% fruiting bodies. Blended and manufactured in the UK.

    What's in it, the compounds researchers look at
    Hericenones
    Found in the fruiting body, the part above ground.
    Erinacines
    Concentrated in the mycelium, the root-like network.
    Beta-glucans
    The structural polysaccharides used to benchmark extract quality.
    The form we use

    Fruiting-body extract, hot-water extracted and standardised for beta-glucans rather than crude 'polysaccharides', a number that can be inflated by starch from grain substrate.

    What the research has looked at

    Lion's Mane is one of the most studied functional mushrooms, with published work spanning nerve growth factor in cell models and small human trials on cognition in older adults. Evidence is early-stage and not sufficient for authorised health claims in the UK.

    Field notes
    • It grows on dying hardwoods, beech and oak, in cascading white spines rather than a cap and stem.
    • Japanese Buddhist monks of the Yamabushi tradition gave it its other name; the mushroom's fringe resembles their robes.
    • Culinary chefs use it as a scallop substitute; the texture is uncannily close when seared.
