    Ginkgo biloba

    Botanical

    A living fossil, this tree species has barely changed in 200 million years.

    Traditional use

    Ginkgo trees survive for over a thousand years, and Chinese temple gardens have protected them for just as long. The fan-shaped leaves have been used in traditional practice for circulation and cognitive support for centuries.

    Provenance, where ours comes from

    From ginkgo trees cultivated in China, where temple gardens have protected the species for over a thousand years.

    What's in it, the compounds researchers look at
    Flavone glycosides
    Standardised extracts are benchmarked at 24%.
    Terpene lactones
    Ginkgolides and bilobalide, unique to the species.
    The form we use

    Standardised leaf extract, used where circulation and attention overlap.

    What the research has looked at

    Ginkgo is one of the most-prescribed botanicals in Europe with a large clinical literature on cognition and circulation, though results across trials are inconsistent.

    Field notes
    • Ginkgo is a living fossil, effectively unchanged for 200 million years, with no close living relatives.
    • Six ginkgo trees survived within two kilometres of the Hiroshima blast and are still alive.
    • Only the leaves are used; the fruit of the female tree smells notoriously of rancid butter.
