Absolute
Absolutes are plant substances extracted using chemical solvents that are later removed as part of the production process.
Adulterant
A substance which was not originally present in the oil at the time of distillation and was later added to an essential oil. Adulterants can be artificial or natural.
Base oil (Carrier oil)
Vegetable or nut oils such as Sweet Almond, Grapeseed, and Jojoba.
CO2s
CO2s are plant substances extracted using carbon dioxide as a solvent to dissolve natural materials.
Common name
Common names are what you will typically hear essential oils called, for example, rosemary or lavender.
Diffuser
A device that disperses essential oils into an area. The three basic types are clay, candle and electric.
Dilute
Adding a small amount of essential oil to a larger amount of base oil to make it safe for use on the skin.
Distillation
A common method used to extract essential oils from plants. Steam distillation is the most common form of distillation.
GC/MS (Gas Chromatograph/Mass Spectrometer)
A device used by analytic chemists to determine the precise make-up of a given substance. Used in aromatherapy to determine the precise chemical constituents of an essential oil, and whether the oil is pure or adulterated with synthetic chemicals or other products.
Essential oil
Highly aromatic substance found in specialized cells of certain plants. Technically, when this substance is in the plant, it is called an "essence." After distillation of a single type of plant, the aromatic substance is referred to as an essential oil.
Herbally infused oil
These are oils that carry the medicinal properties of certain herbs. Carrier oil is infused with the medicinal herb, the plant is strained off, and the remaining oil can be used directly on the skin.
Hydrosol
A hydrosol is the aromatic water that remains after steam-distilling botanical material. Hydrosols can be used in many different ways!
Latin name
Latin (or botanical) names classify the genus and species of each plant. For example, lavender’s latin name is Lavandula angustifolia.
Notes
As in top, middle, and base notes. A type of classification system based on aroma, to identify certain oils. Generally, essential oils from citrus peels are top notes, essential oils from flowers, leaves and stems are middle notes, and essential oils from roots are base notes.
Orifice reducer
A device used to reduce the size of the opening of a bottle, making dispensing the essential oil easier and more accurate.
Pipette
A dropper used in place of an orifice reducer to dispense essential oils.
Resins
A thick, sometimes solid, sticky substance formed when some plants or trees are injured. Frankincense is a good example of an essential oil that starts as a resin.
Synergy
Synergy is created when two oils are blended together in the correct amounts to create a greater total benefit than each oil working on its own.
Viscosity
A measurement of the thickness of a liquid.
Volatile
Describes how quickly a substance disperses itself into the air. In aromatherapy, top note essential oils may be referred to as "highly volatile," meaning that they disperse quickly out of the bottle and into the air.
