Essential oil derived from aromatic plants find wide application in perfume, flavour, fragrance and pharmaceutical and cosmetics industries. There has been a significant increase in demand for essential oils and aromatic plants during the past 35 years. Although, some aromatic herbs/varieties are grown already there is a need to develop cultivation and distillation methods appropriate for newly developed elite strains/varieties of aromatic plants alongwith new end-products and novel strategies. Incorporating essential oil production into farming practices has the potential to benefit all growers of aromatic crops. Many such growers are small farmers with limited resources. Adding essential oil production to already existing operations allows growers to make a new value added commodity with the potential for increased earning and local jobs especially in depressed agricultural areas. The book entitled Essential Oil: Farming of Commercially Viable Crops contains: Bio-synthesis natural isolates and semi-synthetics, Crop modeling and practical application, Adaptation models based on heat unit concept, Chemical composition of Cymbopogon, Mentha and Ocimum species, farming of commercially viable crops: Novel approaches and Essential oil extraction by distillation technology.
