The most useful plant is the olive (Olea europaea) of the Orient, long cultivated in the Mediterranean-region. The oil expressed from the fruit is used as food, and for other purposes. The unripe fruits, preserved in brine, are the olives of commerce. The bark of the fringe tree and privet contains medicinal principles of minor importance, as do also the leaves of the lilac. A saccharine exudation from the bark of Fraxinus Ornus of Sicily, induced by the puncture of a cicada, is manna (See, also, Tamarix mannifera). The wood of olive and ash are valuable. The flowers of Osmanthus fragrans have been used to scent tea in China.
