Origin and history
The oak is undoubtedly one of the most symbolic and revered trees in Europe. Present in temperate forests since prehistoric times, it embodies strength, wisdom, and longevity. Among the Celts, it was the sacred tree of the druids, associated with thunder and divine power. Its name comes from the Latin word * quercus *, meaning "robust tree." Used throughout history for its durable wood, the oak served in the construction of ships, frameworks, and barrels. In herbal medicine, its bark has been used since the Middle Ages for its astringent and tonic properties, while its buds are now used in gemmotherapy to boost vital energy.
