What is Aromatherapy?
Although essential oils have been available for nearly one thousand years, the term aromatherapy was first introduced less than 100 years ago.
Essential oils have been found to provide psychological and physical benefits when used correctly and safely. The Essential Oil Profiles area details over 130 essential oils. Absolutes, CO2s and Hydrosols are also commonly utilized in aromatherapy. Although CO2 extracts and absolutes are not steam distilled and thus are not considered essential oils, the term essential oil is sometimes used as a blanket term to include all natural, aromatic, volatile, plant oils including CO2s and absolutes.
