Citrus Essential Oils include Lemon, Orange, Bergamot, Neroli, Petitgrain, Tangerine, and Grapefruit essential oils. Oils from citrus fruits are extracted by cold pressing the rinds, except for Neroli, which is water-extracted from blossoms, and Petitgrain, which is steam-extracted from stems and unripened fruit.

Citrus Trees are grown in temperate climates all over the world. The fresh, tangy fragrances of citrus oils make them ideal for elevating mood, calming nerves, and reducing anxiety and a valuable addition to perfumes and fragrances.

Citrus oils also act as astringents and can be useful in fighting bacteria because of the high content of limonenes and pinenes.http://www.organicfacts.net/health-benefits/essential-oils/health-benefits-of-tangerine-essential-oil.htmlK.
