The fresh leaves can be eaten as part of a salad and are used in traditional medicine. The flowers are small and fragrant and are used as a stimulant and are mildly purgative. The berries are small and barely noticeable; they are eaten both fresh and dried. The wood of the "Salvadora persica" can be used for charcoal and firewood.
