The humble olive tree, Olea europaea , has been an integral part of human history and culture since its cultivation began in Greece before 3500 BC. It was the original globetrotter, making itself at home from Africa to New Zealand, and made its way to the Americas by the 16th century.

The ancient Greeks loved their olive trees. They weren't just for snacking; olive branches symbolised peace, prosperity, and were the original Olympic medals. They even played a crucial role in marriage ceremonies. The Romans, not to be outdone, used them as peace tokens. This symbolism was embraced by various cultures and religions, with olive branches appearing in Christian, Islamic, and Jewish traditions as symbols of peace and purity.

Olive leaves were the ancient go-to remedy, used for everything from treating fevers to spicing up love life with a bit of magic, seriously. Women would stand beneath an olive tree, back towards the trunk, then pick an olive leaf and toss it over her right shoulder while reciting, “Go forth, little messenger, like Noah’s faithful dove, and bring to me an olive-leaf of love." If the leaf fell to the ground, it meant misfortune in love, but if caught and carried by the wind, it was a sign that she would be a happy wife within a year. ;-)

Olea comes directly from the Latin noun olea , meaning either 'an olive' or an 'olive tree.' Medicinally, olive leaves have been used since ancient times, with their healing properties documented by Greek and Roman texts. In modern times, scientific interest has reignited in the leaf's potential, particularly focusing on oleuropein , a compound known for its astringent, antioxidant, anti-inflammatory, antimicrobial, febrifual, and disease-fighting properties.

Modern day research has explored olive leaf extract's benefits for cardiovascular health, diabetes management, and even anti-cancer potential. Studies also show it's antioxidant and anti- inflammatory properties have exhibited an antiulcerogenic therapeutic option to support gastric ulcers, while taking olive leaf with meals may avoid gastrointestinal discomfort (Winston & Kuhn, 2008).

Furthermore, olive leaf extract has gained popularity as a dietary supplement, especially in light of the Mediterranean diet's heart-healthy reputation. Its use in traditional medicine across various cultures, for conditions ranging from fevers and infections to hypertension and diabetes, has sparked a wave of scientific inquiry into its therapeutic potential.

So, there you have it, a tale of the olive tree: part global traveller, part ancient influencer, and full-time provider of tasty snacks and health benefits. A supremely impressive tree, with deep historical roots and a wide-ranging impact on human culture, health, and religion.
