If used as recommended, and under the care of a qualified practitioner, aromatherapy is very safe. Please remember that essential oils are very concentrated. Do not use too much. (Too much is not better in case of essential oils.) Also, please be wary of any allergies people have to essential oils. (Try on a small spot to see whether there is any allergic reactions before exposing the whole body). Caution is particularly recommended for patients who are pregnant, have allergy, high blood pressure or epilepsy. Be careful with young children or babies. If you accidentally spill the essential oils on your skin or eye, wash it off immediately with whole milk. Milk with some fat in it is best for reducing irritation and removing the oil actually in the eye. You may also use olive oil or other vegetable oil to resolve any issues if experiencing a burning sensation which would be possible with oils like peppermint. Watch out for inflamed skin if you use essential oils. If you consume the oil by accident, drink lot of milk, eat soft bread, and go to the nearest poison control center for appropriate action.

Oral consumption of aromatic oils are strongly discouraged unless you are under the care and supervision of an experienced practitioner. Many of these essential oils are very toxic. You should not apply the undiluted essential oil on your body as these are very concentrated and you may experience discomfort. The exception to this is lavender oil which can be applied safely in the undiluted form for burns and insect bites.

It is a very good idea to keep your eyes closed while inhaling the aromatic oil. This helps build up your imagery which enhances the effect of the essential oil. It also prevents the "fumes" from irritating the eyes at close range. Don't apply any oils close to your eyes.

Certain oils such as mint oil causes insomnia. Do not use it at night (if you want go to sleep.)
