Olive Leaf

Olive leaf

Olive leaf is the leaf of the olive tree. It is used whole as a tea infusion, and as a food additive, primarily in the powder form of olive leaf extract. Olive leaves have rich content of polyphenols, which impart a sour taste.

Olive

The cultivated olive is a subspecies of subtropical evergreen tree in the family Oleaceae. Modern cultivars are traced primarily to the Near East, Aegean Sea, and Strait of Gibraltar. Olea europaea is the type species for its genus, Olea, which lends its name to the Oleaceae plant family. The olive fruit is classed botanically as a drupe, similar in structure and function to the cherry or peach. The term oil was originally synonymous with olive oil.

Leaf

A leaf is a principal appendage of the stem of a vascular plant, usually borne laterally above ground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", while the leaves, stem, flower, and fruit collectively form the shoot system. In most leaves, the primary photosynthetic tissue is the palisade mesophyll and is located on the upper side of the blade or lamina of the leaf, but in some species, including the mature foliage of Eucalyptus, palisade mesophyll is present on both sides and the leaves are said to be isobilateral. The leaf is an integral part of the stem system, and most leaves are flattened and have distinct upper (adaxial) and lower (abaxial) surfaces that differ in color, hairiness, the number of stomata, the amount and structure of epicuticular wax, and other features. Leaves are mostly green in color due to the presence of a compound called chlorophyll, which is essential for photosynthesis as it absorbs light energy from the Sun. A leaf with lighter-colored or white patches or edges is called a variegated leaf.
