Beech (Fagus sylvatica)
Carrying beech wood or leaves as a talisman can increase intuition and creativity. Place the leaves inside the cover of your Book of Shadows as a touchstone to bring inspiration.
Take a stick of beech, scratch or carve your wishes into it, bury it in the ground, and leave it there. Your wish will come true if it is to be.
Beech nuts are edible and quite tasty, though eating excessive amounts of them is not recommended. (Excessive here having the meaning of more than a pound a day.)
Folk Names: Bok, Boke, Buche, Buk, Buke, Faggio, Fagos, Faya, Haya, Hetre
