Essential oils serve a variety of purposes in the health and beauty industries. These concentrated hydrophobic liquids are derived from a plant’s leaves, bark, roots, seeds or other sources, and emit a concentrated aroma that is the ‘essence” of the plant. The oils are extracted from plant sources through distillation, solvent extraction, cold pressing and other methods. Many of these extracts are considered to have strong aromatherapy benefits, with olfactory impulses creating calming or stimulatory effects. Beyond these aromatherapy benefits, some of the most interesting essential oils are used as antiseptics, astringents, rheumatics or diuretics.
