Magical Uses: The date palm is a celebrated fertility tree, owing to the tremendous amount of fruits produced by it. Thusly, dates or pieces of palm leaves are worn or carried for this purpose; dates are eaten to increase fertility, and the pits are carried by men who wish to regain sexual potency.
Where the palm grows, it protects the area from inclement weather, and a leaf of the palm kept near the entrance of the home keeps evil and uncanny creatures from entering.
