Absolute– highly aromatic liquids extracted from plants

Aromatherapy - the use of essential oils and other natural aromatic substances for psychological and physical therapeutic benefit.

Botanical Name - the Latin name given to a species of plant to clearly distinguish it from other plants that share the same common name. Examples: Roman Chamomile's botanical name is Anthemis nobilis. German chamomile's botanical name is Matricaria chamomilla.

Carrier Oil - Oils used to dilute essential oils, CO2s and absolutes before applying to the skin. They “carry” the essential oil onto the skin.

CO2s –oils extracted by the carbon dioxide method. CO2s are extracted by pressurizing carbon dioxide until it becomes a liquid. The liquid carbon dioxide then acts as a solvent on the natural plant matter and the essential oil content then dissolves into the liquid CO2. Afterwards, the CO2 is brought back to natural pressurization, the CO2 evaporates back into its gaseous state and what is left is the resulting oil. CO2s are often labeled as essential oils as opposed to absolutes since no trace of a harmful solvent will remain in the final product.

Common Name - The "everyday" name given to a plant. Examples: Bay, Chamomile, Cedar, Orange, Tea Tree and Eucalyptus. Because of the possible confusion between common names referring to different species, the botanical name is utilized for clarity. When purchasing essential oils, be sure you refer to the botanical name.

Essential Oil – An essential oil is a liquid that is generally distilled by steam or water from the leaves, stems, flowers, bark, roots, or other elements of a plant. Essential oils, contrary to the use of the word "oil" are not really oily. Most essential oils are clear, but some oils such as patchouli, orange and lemongrass are amber or yellow in color.

Fragrance Oils -artificially created fragrances, contain artificial substances or are diluted with carrier oils and do not offer the caliber of therapeutic benefits that essential oils offer.

Orifice Reducer - a small, usually clear insert found inside essential oil bottle openings that acts as a dropper. By tipping the bottle and you can dispense the oil drop by drop.

Perfume Oils – same as fragrance oils

Pipette - a disposable plastic dropper used in place of an orifice reducer or an eyedropper for dispensing essential oils.

Synergy - the total benefit of essential oil blends rather than each one working independently.
