Essential Oils and Cosmetic Aromatherapy

Abstract

Aromatherapy uses essential oils, as the main therapeutic agents, which are secondary plant metabolites, aromatic in nature and give distinctive odour or flavour to plants. Chemically, they are complex mixtures comprised of a large number of saturated and unsaturated
hydrocarbons, alcohol, aldehydes, esters, ethers, ketones, oxides phenols and terpenes, in variable ratios.
