Esters occur when acid and alcohol molecules bond together. This bond creates chemicals that are gentle on the skin and have balancing energetics. Aromatically, they are often flowery and/or fruity middle notes, and their shelf life is usually 3 - 5 years.
Essential oils that are ester-rich are generally soothing, uplifting, and sedative. They can help balance your body during times of high stress. Several can relieve pain and inflammation. They are great on skin irritations like bites, stings, rashes, and skin conditions, and some can even help improve digestion.
Overall, essential oils high in esters are safe to use, but there are some precautions that need to be taken into consideration.
* The acid-alcohol bonds can be broken if the essential oil is stored improperly (i.e. in a hot, humid area like a bathroom), therefore, store these oils in a cool, dry area.
* Wintergreen and Birch Essential Oils have an ester - methyl salicylate - in very high levels. [This chemical is the plant remedy used before aspirin, and is the inspiration behind the creation of aspirin (aspirin = acetyl salicylate).] These oils need to be used by adults only and in low dilutions for limited time periods. This chemical constituent is not easily processed by the human liver and can reach toxic levels if used improperly. See the datasheets in the membership section for more information. If you are allergic to aspirin, do not use Wintergreen or Birch essential oils.
