Safety Guidelines



Every book you will ever find on essential oils has a section of cautions and safety guidelines, a fact that could be considered very helpful if any of them agreed on anything and if they were based on facts gleaned from valid studies! Most of the books published and sold in America lean to the British way of thinking. Perhaps this is because of the language barrier between texts written in French and the English-speaking people who are reading them.

If you follow the studies quoted in the majority of aromatherapy books written from the British point of view, you will find that the studies were done on animals, or were done with single components of an oil (essential oils which were broken down, and therefore, altered in a laboratory before the testing began), or were done using non-therapeutic, perfumery grade oils for the test. The concerns raised as a result of these tests are of very questionable validity when discussing the subject of pure therapeutic grade essential oils. In fact, I doubt it applies at all.

Always consider the bias of the book you are reading. There are books full of cautions that really do not apply to your everyday use of therapeutic grade essential oils. On the other hand, essential oils are very concentrated plant material and are biologically active. They penetrate into the tissues and cells of the body. Because they are active agents, essential oils can, of course, be misused and even over-used. The relative safety of essential oils is different depending on the method of use.

It would be difficult, probably impossible, to inhale a lethal dosage of any essential oil, or to absorb such a dosage through the skin. You may irritate your nostrils or lungs, break out in a nasty rash, or trigger a cleanse response by the body, but you will not do yourself serious harm if the oils you are using are pure and non-synthetic. The drugs you have taken play a factor in the nastiness of a cleanse reaction.


The oral ingestion of essential oils is another matter altogether. I do not recommend the taking of essential oils internally. The proponents of internal ingestion will tell you that when serious overdoses (meaning death) have occurred it was either deliberate on the part of the person or was an accident with a child. The death of a child is always a tragedy and being accidental does not mitigate that. In addition, the “accidents” I have read of with children would be better termed “criminal stupidity.” When a substance is making a child seriously ill it is time to stop using it and find an appropriate antidote and a way to cope with the overdose! Nevertheless, because essential oils are very concentrated, enough of an overdose to cause illness and harm to a child with internal use would be very easy to accomplish. Even with an adult, a great deal of caution and thought should be taken.

The rest of the story is that in studies conducted at universities in both Germany and Austria, essential oils were placed on the feet and then detected on the tongue in 20 minutes. Essential oils absorb so readily into the body and pass through the cells to the needed areas so efficiently that it would rarely be of any additional benefit to take them orally. There are even studies indicating that the rate of travel and the site targeted are responsive to the thoughts and intents of the user.

I have been using essential oils for many years with grand results, and I have never felt the need to use them internally. I brush my teeth with them. I gargle with them, and occasionally, I even use them in a water pick. If I need them somewhere internally I trust the oil itself to find the best path there from use in an external application of some kind. The purity of the oil does not change the fact that they are extremely concentrated plant material and can be easily overdosed when taken internally. Being a therapeutic grade essential oil does not make that oil automatically safe to be taken internally. Therapeutic grade does eliminate a host of ills unrelated to concentration and strength. Synthetic, man-made versions are extremely dangerous taken internally and just plain dangerous used otherwise!

With that said, I would like to add that the essential oils sold by Nature’s Body Shop, are therapeutic grade essential oils. The choice, and the responsibility, for their use internally is all yours. Just remember, we do not advocate internal use of essential oils.

I can find no record of recent deaths, or even serious injuries, linked to the proper use of essential oils. This is true in spite of the fact that more and more people are using them every day. The American Medical Association, in reports of their own, admit that hundreds (some claim thousands) die every year from properly applied pharmaceutical drugs. Essential oils are among the safest and most effective of all therapeutic modalities. They are safe enough for amateurs and novices to use with only the remotest possibility of causing harm to themselves and others. As always, the more you know the more effective and safe you will be.



The very first rule is, of course, to keep your oils out of the reach of children. Think of and store them just as you would any other therapeutic product containing active ingredients. This means that you do not leave bottles of oil sitting on the side of the tub or anywhere else.

When applying oils to infants and small children, always dilute with a carrier oil. 1 to 3 drops of essential oil in 1/2 teaspoon (or even more) of a carrier oil will do the job nicely without the risk of skin irritation or overdose. If a child does get hold of a bottle of oil and either dumps it in the tub or all over themselves, the solution is carrier oil applied liberally and frequently. The carrier oil will dilute the oil, slow down the rate of absorption into the body, and relieve much of the discomfort of the skin irritation.

Vegetable protein oil (carrier oils) such as olive, almond, grapeseed, safflower, etc., are excellent to use whenever too much oil has been used or an oil has reached the wrong place (the eyes, the mucous membranes of the nose, or other sensitive areas). Do not use water. Water amplifies the effects of the oils and carries it even more quickly into the


Many oils which contain furanoids are considered phototoxic. This means that if the skin where the oil was applied is then exposed to a source of ultraviolet light, it will absorb more UV radiation at a faster rate. This is supposedly true even when the oil has been diluted with a carrier oil to be applied. Please note that the oil must have been applied to skin which is then going to be exposed. Putting a phototoxic oil on your chest or feet and then exposing your arms and face to sunlight does not create a problem. Also consider that the tests run on these oils were laboratory tests. The oils had been broken down into individual components and the furanoid compounds were tested that way—without the other constituents that make them safe to us. I, personally, pay no attention to phototoxicity and have never had a problem.

Apparently, furanoids can resonate with UV light in two opposing ways, either to magnify the UV waves, or the furanoids can result in the destruction of the UV radiation. In myrrh oil, for example, there are compounds that quench the solar amplifying properties.

Ancient Egyptians applied myrrh oil on their skin daily. Myrrh is an example of how the compounds of living things change their behavior according to the company they are in. Testing individual components for toxicity does not tell you much of anything useful! Oils which are considered to be phototoxic include angelica, bergamot, orange bitter, grapefruit, lemon, lime, petitgrain, and rue. Some sources include fennel, anise, and cumin on this list. Notice that not all of the citrus oils are included. Oils of mandarin, orange sweet, tangelo, and tangerine are NOT considered phototoxic.


Essential oils are very beneficial for many of the conditions of pregnancy, but caution, of course, should be used. Pay close attention to the lists of oils which are contraindicated for pregnancy, but do factor in the bias (British, French, or German) of the book you are consulting. Always begin with only half the dosage that you would ordinarily use.

Remember that blends, because of the smaller percentage of the stronger oils, are usually safer than single oils, especially during pregnancy.

Oils that are known to have estrogenic/hormonal properties should be avoided during pregnancy, or at least used with great caution. These oils include clary sage, sage, calamus, anise, myrtle, wild tansy, and fennel. Blue tansy, tarragon, and cypress should also be used with caution and consideration.

Other oils listed in books of the British persuasion include basil, cinnamon, juniper berry, marjoram, rosemary, thyme (red and linalol), oregano, clove, nutmeg, bay, pimento berry, cistus, hops, valerian, spikenard, black pepper, cedarwood, hyssop, myrrh, peppermint, mace, cumin, parsley seed, wintergreen, and birch. I am sure that all of these oils have a high risk of creating a problem if they are synthetic, rather than therapeutic grade essential oils. Synthetic oils are a risk to everybody!

A pregnant woman is responsible, for a time, for a life other than her own. She should always be cautious and sensible, especially with substances as concentrated as essential oils. Experience, caution, and paying attention to the cautions lists (which are based on someone else’s experience) are the best ways to remain safe in the use of essential oils.


These oils include Bitter Almond, Boldo Leaf, Yellow Camphor, Horseradish, Jaborandi Leaf, Mugwort, Mustard, Pennyroyal, Thuja, Tansy, Rue (as a single oil), Sassafras, Savin, Southernwood, Wormseed, and Wormwood. These oils should never be used during pregnancy, of course.


Always proceed with caution in these cases. There has almost always been the administration of anti-seizure medications. Triggering a cleanse from these substances can be a nasty, possibly even deadly, experience. Always use small amounts of the essential oil and space the time of usage out well, at least for the first few days. The detoxification method suggested just a few paragraphs further on may help in avoiding problems or in dealing with the less drastic ones should they arise.


Essential oils are very powerful substances that should be treated with respect. They are highly concentrated plant extracts and should not be used rashly and without knowledge or thought. Each drop is equivalent to at least one ounce of plant material. In most cases, essential oils are more effective in infinitesimal amounts, anyway. Increasing the dosage or amount applied will not usually increase effectiveness.

Begin with a small amount. You can always add more to the bath, to the skin, to the diffuser. You, or the person you are working with, have survived this long without using that particular oil. Another day or two, to gradually bring up the dosage to your personal tolerance level, will be time well spent.


The use of the oil has triggered a cleanse in the body. Toxins, heavy metals, chemicals, poisons, parasites, or mucous are being pulled from cells, particularly the liver, and then filtered through the body’s eliminative organs. This can cause a stress reaction in the kidneys and bowels or manifest as a rash if the body uses the skin to eliminate the poisons. Support the eliminative organs (kidney, colon, skin) in any way that you know how and consider slowing down the use of the oils until your system catches up. When the body is detoxifying at too fast a rate, the toxins that cannot be eliminated simply return to storage in new places—often the brain stem—and have to be dealt with all over again later.


Run a tub of warm water (quite hot, but not hot enough to be debilitating). Add 3 tablespoons of *redmond clay or 1 cup sea salt (or Epsom Saltssea salt is preferable) and soak for at least 20 minutes. Allow time to rest afterwards as you may feel weak and tired for a time.

Soaking just the feet in hot water to which 2 tablespoons of redmond clay has been added is almost as effective and not as debilitating as soaking the entire body. Be sure to keep the water quite hot.

  1. The second reason that a person might have a negative reaction to a particular oil is a simple allergy or an intolerance to the plant from which the oil was made. Oils are made from plant material and they are very concentrated; hence, a person may not realize that they have a problem with a particular plant until they use the oil. Allergic reactions are quite rare in working with essential oils and usually mild when they do occur. An allergic reaction can often be minimized, or dealt with altogether, by using basic energy procedures, massage therapy, or you might try the following:
    1. Put Unanimity on the palms of both hands.
    2. Place one hand over the thymus (heart chakra) and the other hand over the navel.
    3. Take 3 deep breaths and switch hands, then take 3 more deep breaths.

There is no substitute for common sense and caution. Only you are responsible for your own health and welfare, and you must use these wonderfully beneficial substances responsibly.

As with all essential oils, never use them undiluted. Do not take internally unless working with a qualified and expert practitioner. Keep away from children. If applying an essential oil to your skin always perform a small patch test to an insensitive part of the body (after you have properly diluted the oil in an appropriate carrier.
