Many essential oils can be taken internally, when directed by qualified professionals if they are truly 100% pure, with nothing added or altered. Because of our Western medicine indoctrination, many of us here in the United States do not realize that we do not need to take essential oils internally. Unlike pills or prescription drugs, essential oils can give us great benefits just by rubbing them onto the skin. As a matter of fact one of the best methods to use essential oils is by massaging them directly into the bottom of the feet.
Now if you are going to take essential oils internally you will want to make sure you never ingest these oils: Artemesia, Birch Bark, Eucalyptus Globulus, Eucalyptus Radiata, Pennyroyal, and Wintergreen. These oils contain harmful chemical properties that if taken internally can do great harm or even kill in small amounts.
All the other essential oils in smaller amounts are considered safe, but remember to use caution when working with Nature’s pharmacy. Naturally if a person was to drink a couple of gallons of Tea Tree oil there is a high chance that it would be fatal to the average person. Then again, if you were to eat one pound of salt you might die. Even water, something we should be drinking a lot of each day, can kill if we ingest too much of it at one time.
Another good reference guide is the FDA’s GRAS list. That stands for Generally Regarded As Safe.
Always remember to use essential oils with caution and with the care of a qualified professional.
