DANGERS OF ESSENTIAL OILS
1) As there are many hundreds of essential oils, it is not possible to guarantee that the above precautions comprise a complete list. Therefore, always consult a qualified Aromatherapist, when in doubt.
2) If you have a serious medical condition, always consult a medical Doctor, who has specialized in Medical Aromatherapy, before using essential oils.
3) Do not use essential oils if you are trying to fall pregnant.
4) Do not drink essential oils. Even a few drops, in a cup of tea, could cause stomach ulcers, bleeding, or diarrhea.
If, however, you are under the care of a Medical Aromatherapist holding a Doctor’s Degree, they will be able to choose safe oils for you to drink.
5) Do not let children near essential oils, as they could apply the concentrate to their skin, or drink it. Keep oils locked away.
6) Essential Oils are concentrates, so they can burn your skin, unless you dilute them correctly.
Only Lavender and Tea Tree can be used undiluted, and even then, just one drop applied to an area of skin. Water can be used to ‘spread’ these 2 Essential Oils.
If you follow all the information above, which has been summarized from the top 5 published Aromatherapists in the world, Essential Oils are safe to use, and impart a wide variety of health benefits, as long as you dilute them in carrier oils, or in body butters.
Also, study up on how to safely blend oils.
