How Safe Are Essential Oils?
Are Essential Oils Safe? These Are The Important Things You Need To Know
Whether you use essential oils for their fragrance, for health, or for esoteric and magical purposes, it is important to remember that they are highly concentrated plant extracts. They need to be used with care and respect.
So how safe are essential oils? I would say that essential oils are safe in the same way that cars are safe when driven with skill, awareness and following the rules of the road.
There are some oils that although available, should not be used in conjunction with certain conditions, and some that should not be used at all, due to their toxicity. They are listed in the section on warnings below. Oils not on these warnings lists may still be contra-indicated for certain conditions, and it is recommended that you always check with your medical practitioner if you are taking medication, are being treated for a medical condition, or have doubts about the appropriateness of any essential oil treatment.
Apart from the oils listed in the warnings section, there is always the possibility that certain people might find that they have an allergic reaction to a particular oil. For example, I and many people use neat Lavender oil with great pleasure and efficacy for many things, but I know that there are those that find that it irritates their skin, and need to dilute it.
For this reason, it's always a good idea to try out any oils and blends at their weakest solution first on a small patch of skin, and leave for 12 hours just to check. It is extremely rare, but everyone is different, and there can never be a one size fits all rule in things like this.
SAFETY GUIDANCE FOR THE USE OF ESSENTIAL OILS
Do not ingest the oils:
Essential oils are highly concentrated, and by themselves can irritate and burn the mouth delicate and gut lining.
Be very cautious and sparing using essential oils in cooking:
Some essential oils, such as Peppermint, Orange, Lemon and Lime are used in commercial food and confectionery preparation, but there are also oils that are positively unsuitable to internal use. You need to know the difference, and if your knowledge of oils is limited, it is best to avoid using them in this way completely.
Avoid skin and eye contact with undiluted essential oils
Always wash your hands after opening essential oil bottles to avoid transferring oils to eyes, nose and mouth, or any other tender parts. Certain people find that undiluted oils irritate their skin, and everyone will find essential oils extremely unpleasant, and possibly damaging if transferred to the eyes.
Keep individual oils uncontaminated, and ensure their longer life and effectiveness:
Over time, during handling and use, oils become contaminated by the transfer of other oils on the hands. Always use dropper bottles, and allow the oil to discharge naturally without touching the dropper tip. In an instant, an oil is contaminated by contact with skin, so smell oils by putting a drop on a tissue or hanky, and not your skin.
Don't leave essential oils, oil blends or aromatherapy burners with infused water within the access of animals or children.
Essential oils will cause oil marks on materials and clothing, and may affect certain surfaces.

Phototoxicity, Photosensitization and Sun Sensitivity
Some oils, when applied to the skin, cause the skin to burn when exposed to sun-light. This is known as Phototoxicity, Photosensitization and Sun Sensitivity.
This does not mean that these oils increase or speed up tanning; they simply cause the skin to burn. Because of this side effect, phototoxic oils should not be included in sun tan oils or day face and body creams.
After any application of photosensitizing oils, whether by aromatherapy massage, or self treatment, exposure to the sun should be avoided for at least 12 hours. In practical terms, this means using these oils in the evening and at night, although they are fine to be used in a diffuser at any time.

Essential Oils In Pregnancy
The benefits to general well being, and relaxation that essential oils can bring make it an extremely helpful therapy during pregnancy.
However care must be taken with the choice of oils used in baths, massage oils and inhalations.
Some oils contain chemical compounds that stimulate menstruation; (these are called Emmenagogues), and some contain chemicals that have hormone-like molecular structures. Although there is no solid data as to their effect in pregnancy, it is always wise to err on the side of caution and give these oils a miss, as well as the known toxic oils.
