    Holy Basil

    Ocimum sanctum

    Adaptogen

    Tulsi, a plant so valued in India that it grows in a place of honour in courtyards across the country.

    Traditional use

    Revered in Ayurveda as an 'elixir of life', Holy Basil has been sipped as a daily tea for millennia to promote calm balance and clarity. It's traditionally planted near temples and homes as a guardian herb.

    Provenance, where ours comes from

    Grown in India, Tulsi's homeland, where it has been cultivated beside temples and courtyards for thousands of years.

    What's in it, the compounds researchers look at
    Eugenol
    The aromatic compound also found in clove.
    Ursolic acid
    A triterpene common in aromatic herbs.
    Rosmarinic acid
    A polyphenol shared with rosemary and sage.
    The form we use

    Leaf extract, standardised and used in our calming blends alongside Ashwagandha.

    What the research has looked at

    Tulsi has a substantial ethnobotanical record and a growing set of small clinical studies on stress and wellbeing measures in India.

    Field notes
    • Tulsi is grown in courtyards across India and treated as sacred rather than merely medicinal.
    • It is a different plant from the sweet basil in pesto, though they're cousins.
    • The leaves are peppery and clove-like, that's the eugenol.
