There are certain oils that are photosensitive, meaning you don’t want to wear them and go outside. These are mostly citrus oils, like grapefruit, lemon, etc.
When using on your skin, always watch for redness and dilute with a carrier oil. Dilute oils on children, because their skin is more permeable and absorbs the oils more quickly. What is a carrier oil? It’s a fatty oil like olive oil or coconut oil, and its molecules are much larger than those of essential oils. Using a carrier oil with an essential oil slows down the rate the body can absorb the essential oil, because it has to ping pong through the large molecules of the carrier oil to get into your skin.
Be wary of putting the oils topically near your eyes. Some oils, like peppermint, can cause a burning sensation. If you are placing an oil near your eye, apply the oil to a Q-tip instead of tipping the bottle towards your face.
You can become desensitized to an oil if you use the same one day after day, so I rotate my oils every three to four days.
What about internal use of essential oils? NAHA, one of the top aromatherapy schools in the United States, doesn’t advocate essential oils for internal use. Why? Most oil companies don’t carry any GRAS (Generally Regarded As Safe) essential oils which have been cleared by the FDA. NAHA also bases a lot of their decision on the British model, which advocates topical use only. Many of the British studies are flawed, for example, done at extremely high doses or in ways the oils aren’t used, like pouring a bottle inside the body. Young Living utilizes all three methods, British, French and German. The French have been safely using some essential oils internally for decades. Young Living has created a Vitality line with distinctive labels so you can easily recognize which oils are safe to take internally.
