Cupressus sempervirens also called “Mediterranean cypress” or "Pencil pine"is a species of cypress native to the eastern Mediterranean region and belongs to the family Cupressaceae. It is a medium-sized coniferous evergreen tree to 35 m tall, with a conic crown with level branches and variably loosely hanging branchlets. The foliage grows in dense sprays, dark green in colour. The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots. The seed cones are ovoid or oblong, green at first, and maturing brown. It is very long-lived, with some trees reported to be over 1,000 years old. The young twigs, stems and needles of the cypress tree are steam-distilled, and the essential oil has a clean and energizing aroma. The main constituents of cypress are alpha-pinene, carene and limonene; the oil is known for its antiseptic, antispasmodic, antibacterial, stimulating and antirheumatic properties.
