Oak as an Herb

Oak as an herb

Quercus robur

Other Names: Common Oak, Pedunculate Oak, English Oak,

The Oak, although widely distributed over Europe, is regarded as English. The Greeks held the Oak sacred, the Romans dedicated it to Jupiter, and the Druids venerated it.

In England the name Gospel Oak is still retained in many counties, relating to the time when Psalms and Gospels were spoken and shared beneath their shade. Many of these Gospel trees are still alive in different parts of England. Oak trees were specially selected to read passages from the Gospels, and ask blessings for the people.

An old proverb relating to the oak is still a form of speculation on the weather in many country districts.
