Powers: Since the oak was a source of food for early settlers in Britain as well as Europe, it came to be revered and worshiped far back in prehistory. The Druids (traditionally) would not meet for rituals unless an oak was present, and the very words "oak" and Druid" some say, are related. Witches often danced beneath the tree.
Magical Uses: A tree as long lived and strong as the oak naturally offers magical protection. Two twigs of oak, bound with red thread so that they form a equal-armed cross, makes a potent safeguard against evil. It should be hung in the house. A piece of oak wood, carried, protects its bearer from all harm. Carrying any piece of the oak draws good luck.
