Olive oil is an excellent treatment for the skin and hair, and it delays old age.Green olives are the most nourishing, and counteract auto intoxication. Black olives cause the spleen to overproduce bile and are hard on the stomach. Olive leaves can be chewed as treatment for inflammation of the stomach, skin ulcerations, and eruptions of herpes and hives.
Allah has said of the olive tree: “And a tree that grows out of Mount Sinai which produces oil and a condiment for those who eat. For olive oil is the supreme seasoning.” Allah has also called it the Blessed Tree [Qur’an 24:35]
