    Sage

    Salvia officinalis

    Botanical

    From salvare, 'to heal', the Romans treated this herb like a pharmacy in a leaf.

    Traditional use

    A medieval proverb asked 'why die when sage grows in the garden?', and European monasteries cultivated it for memory and mind for centuries. It was traded down the Silk Road so eagerly that tea was exchanged for it at four times its weight.

    Provenance, where ours comes from

    A Mediterranean native, still grown in the sun-baked herb gardens of southern Europe, as it has been since Roman times.

    What's in it, the compounds researchers look at
    Rosmarinic acid
    The dominant polyphenol.
    Carnosic acid
    A diterpene studied for antioxidant behaviour.
    Thujone
    Present in the volatile oil; why sage extracts are dose-controlled.
    The form we use

    Standardised leaf extract at a level that supports an authorised claim: sage contributes to normal cognitive function, the one claim in FOCUS we can state outright.

    What the research has looked at

    Sage has been examined in several small randomised trials on memory and attention in healthy adults, and holds an approved cognitive-function claim in the UK.

    Field notes
    • Salvia comes from salvere, 'to save'. The Romans named it after what they expected of it.
    • There's an English proverb: 'Why should a man die whilst sage grows in his garden?'
    • It was the strewing herb of choice in medieval sickrooms, for its scent as much as anything.
