Always dilute essential oils before use. Many essential oils may cause burns and excessive irritation when used neat. There are a couple of exceptions. For example, occasionally you can apply 1 drop of neat lavender onto a pimple, insect sting or small cut using a cotton bud. Always dilute though when applying on children.
Do not take essential oils internally. Unless you or the aromatherapy practitioner are properly trained in the safety issues of internal uses of essential oils, it is best avoided.
Do not place essential oils directly into your bathwater as essential oils and water don't mix together. You will need to mix your essential oils in either milk, a carrier oil or an unscented bath and shower gel first before adding to your bath.
Try to vary the essential oils that you use on a regular basis. This can help you to avoid developing sensitivities to your most used essential oils.
When it comes to using your essential oils, try to remember that less is more. Essential oils are highly potent and sometimes just 1 drop will do.
When diffusing essential oils, try to do so for only around 15-30 minutes per session. Take a good break in-between each diffusing time.
Keep essential oils away from children and pets.
If diffusing essential oils when your pets are around, always make sure that you have adequate ventilation and that your furry friend can leave the room easily.
