One key point of any aromatherapy oils guide is the fact that essential oils should be treated with respect and in the dark
They are damaged by ultraviolet light and deteriorate more rapidly at the blue end of the spectrum than the red. Therefore, the essential oils reference guide tells us we should be stored in amber-coloured bottles (if you do keep your essential oils in blue bottles then they should be kept in the dark – this is less important if your bottles are brown).
Never decant the oils into clear glass or plastic bottles. They should never be placed in direct sunlight, so avoid sunny windowsills or shelves on radiators – no matter how attractive the bottles look! The quick reference guide for using essential oils tells us that essential oils do not like extremes of temperatures. They are highly volatile which means that they evaporate rapidly. Always replace the caps immediately and ensure that the tops are tightly closed when the oils are not in use.
Essential oils reference guide tells us that essential oils will last for approximately three years from the bottling date. In excellent storage conditions (i.e. amber bottles in a cool place with no air space) they will keep for about five years. Citrus oils tend to have a shorter shelf-life due to their high proportion of terpenes, as do absolutes and resins which thicken even more with age and the smell of the solvent becomes more noticeable.
Once essential oils have been diluted in a carrier oil, the shelf-life reduces dramatically. For maximum benefit use freshly made-up blends. A blend will keep for about three to six months if it is stored in an amber-coloured bottle in a cool place away from sunlight. If wheatgerm oil is added then the shelf-life is approximately six to nine months. Also, the essential oils reference guide tells us that if the smell alters and the vegetable oil becomes rancid then you should definitely discard it.

- Clear glass or plastic bottles do not contain pure essential oils. Always buy oils in amber-coloured bottles.
- How old are the essential oils? When were they bottled?
- Are the oils in direct sunlight?

- If blends are being sold, is there a qualified aromatherapist on the staff?
- Has the supplier been recommended to you?
- How long has the aromatherapy firm been established?
- Essential oils should always be kept away from young children. If they are taken internally some essential oils can be highly dangerous.
