The use of aromatics by mankind dates back almost 4000 years ago. Before modern day perfumes were made by chemists and available in department stores, they were created by making a solution of organic plant extracts in an alcohol solution. Plants are the major source of aromatic compounds utilised in Perfumery. Many segments of a plant can be used for their aromatic properties. For instance orange leaves produce petigrain oil, neroli oil is derived from orange blossoms and orange zest produces orange oil. Other parts of a plant made use of in Perfumery are bark, fruits, twigs, resins roots, rhizomes, bulbs, seeds and woods. It is said that perfumes produced in the traditional way are imbued with a depth of character and beauty rarely found in modern perfumery.
