Self-Education is Critical & Are Essential Oils Safe?

 Education is critical and we must take responsibility for ourselves and learn.  We are destroyed for lack of knowledge.  When using essential oils and natural products, we MUST-MUST-MUST educate ourselves. 


It is YOUR responsibility to educate yourself and not that of the provider of the essential oils.  We provide some information on the oils but it is up to you before using them to educate yourself not only in their benefits but also in any possible side-effects and interactions that could be possible for your individual case.  This includes  over-the-counter as well as the precscription medications and herbal remedies you may be taking .


There are so many sources of information you can find to educate yourself I have listed  but a few that are available to us; the internet,  books, magazines, ebooks and videos. There are also seminars and webinars we can attend to name just a few ways to educate ourselves. The good news is for the most part, it is a free education to all who will seek!


It's important to remember:


More is not better when it comes to the use of essential oils.  They are highly concentrated plant essences which means they are potent and powerful!  Unless your physician should tell you to ingest Essential Oils....we here at Bishop's Select Essentials stress that you only use them externally and DO NOT take them internally for any reason!


Always test the oil on the inside of your elbow for sensitivities before doing a body rub or massage!  Sometimes you can simply dilute them more with the carrier oil of your choice and most households have olive oil on hand which is fine to use.  Before diffusing, take a couple of sniffs, if you find the scent highly unpleasant or sense nausea or any type of negative reaction DO NOT CONTINUE without further investigation and education!  Your safety must be priority!


If you are sensitive and you do get a skin reaction.....wash with soapy water, rinse well and then dry, follow by applying pure olive oil.   It should feel better immediately and the redness should begin to fade soon.  If not, seek medical attention.


Here at Bishop's Select Essentials we do  not advise taking the Essential Oils orally....period!  If somone should ingest them without the approval of their medical care provider or other such professional, seek prompt medical attention immediately!


If you are allergic to a particular food, you will also be allergic to its essential oil.


Always find out any possible interaction that an essential oil may have with any prescription medication you may be taking, this includes but is not limited to any over-the-counter pills, liquids, creams, rubs etc. that you may be taking/using and also any herbal remedy.


Consult your competent practitioner for all issues related to your own personal health. The information on this page and this site has not been evaluated by the FDA. It relates to historical application of essential oils and should not be construed as claims or medical advice.


Are Essential Oils Safe?

  Most essential oils are safe and free of adverse side effects when used properly. However, as with any substance you are introducing into your body, it is important to use them intelligently. We recommend that you never eat or drink essential oils. You should pay attention to the following factors.

·                        Dosage. Dose is the most important factor in essential oil safety. Some essential oils used in the wrong doses or too high a concentration have been found (in animal and laboratory studies) to contribute to tumor development and other harmful changes in the body. Some essential oils can even be damaging to the skin, liver and other organs if used improperly.

·                        Purity. Sometimes essential oils are altered by adding synthetic chemicals or other, similar smelling, essential oils or they are sometimes diluted with vegetable oil. Look for language indicating purity on the label. It is not necessarily bad if the label indicates, for example, that the bottle contains 20% essential oil and 80% vegetable oil. This is sometimes done so that popular but expensive oils like rose or neroli (that can cost over $100 per teaspoon when pure) can be made more affordable. If you think you are starting with 100% essential oil and you are not, however, you may be disappointed with the results. On the other hand, if you are starting with professional quality essential oils, which are generally much more concentrated, you need to dilute them to be safe.

·                        massage application of essential oilsApplication Method. An essential oil that is safe when applied in one way may not be safe when used in another way. Some oils are considered safe if inhaled, and yet may be irritating if applied to the skin in concentrations as low as 3-5%. Thyme, oregano, clove, and cinnamon bark essential oils are examples of this. Several of the citrus oils, such as bergamot, lemon, lime, orange, and angelica, can cause phototoxicity (severe burns or skin cancer) if there is exposure to natural sunlight or sun-bed radiation following skin applications, whereas this would not result from inhalation.

Be sure to clarify the recommended application method and concentration for the essential oil and intended use. And once again, don't ingest oils without professional guidance.

·                        Possible Drug Interactions. There is little published research on interactions between pharmaceutical drugs and essential oils. Given the complex chemistry of essential oils, however, it makes sense that this is possible or even likely. As with dietary supplements and herbs, it is important to discuss regular essential oil use with your healthcare provider and together assess any potential risks and benefits. For example, studies indicate that peppermint and eucalyptus oils increase the skin absorption of 5-fluorouracil, an anti-cancer drug (Abdullah et al 1996, Williams & Barry, 1989).

Can essential oils be toxic?

Toxicity rarely occurs with appropriate use of essential oils and is primarily attributed to misuse and accidental ingestion, especially in young children. Essential Oil Safety by Tisserand and Balacs, 1995, is a valuable reference to understanding potential toxicity and lethal dosages. Again, we recommend that you never eat or drink essential oils.

Don't Forget to Dilute

As stated earlier, it is important to note that most essential oils can not be applied directly to the skin (without being diluted). Refer to the section "How do I choose and use essential oils?" for more information on dilution and carrier oils.

Special Considerations

In general, you should adjust dosages downward for children, but also use extra caution in choosing essential oils to be used in babies and children (or avoid use altogether). Some essential oils, such as peppermint, should not be used with children younger than six years old. Menthol-one of the major chemicals in peppermint oil-has caused breathing to stop in young children, and has caused severe jaundice in babies with G6PD deficiency (a common genetic enzyme deficiency) (Price & Price, 1999). 

lavenderYou should also exercise caution with essential oils if you are pregnant, since essential oils can cross the placental barrier and there is little clinical research in this area. Very gentle essential oils, such as true lavender (Lavandula angustifolia) are sometimes used by midwives during and after labor and delivery with favorable effects (Burns et al., 2000).

In general, however, similar cautions during pregnancy and infancy/early childhood should be used with essential oils as with other substances. If you are in doubt, contact a knowledgeable healthcare provider. 

Always store essential oils out of reach of children, in bottles with single-drop dispensers. Accidental ingestion of amounts as small as a teaspoon has resulted in death.

Could I have an allergic reaction?

A small proportion of people may experience skin irritation, allergic reactions, or cross-sensitivity to essential oils. Cross-sensitivity is the potential for an allergic reaction to similar substances (for example, if you are allergic to ragweed, you might also be allergic to chamomile essential oils). 

Irritation is characterized by a rapid onset redness and pain in the skin exposed to the essential oil. It can occur with the first exposure. The skin generally heals without long-term problems, but you probably would not want to use the essential oil that caused the irritation again. 

Some problems of this sort have been caused by oils adulterated with synthetic chemicals or chemically changed by exposure to heat or light over time. Thus, if you really like the essential oil that seemed to cause the skin irritation, you might try a different brand (following the guidelines given previously for choosing essential oils).

Contact Sensitivity

Contact sensitivity is a type of allergic reaction. This can happen anytime after the first exposure to an essential oil, and usually presents as an itchy rash or hives. This is caused by the immune system's response to one or more of the chemicals in the essential oil. The extent of the reaction may seem out of proportion to the amount of exposure. Again, old or altered essential oils are more likely to produce skin reactions (Tisserand & Balacs, 1995).

Patch Testing

Patch testingIf you are someone who is taking a lot of prescription medication and/or has a lot of allergies, you should do a patch test by following the instructions below to check for skin irritation and sensitivity before using each essential oil. 

To do a patch test:

·                        Mix a very small amount of essential oil/carrier at twice the concentration you plan to use. For example, if you plan to use a 3% mixture of the essential oil, mix it at 6% (six drops in a teaspoon of carrier oil, or three drops in ½ teaspoon of carrier oil).

·                        Using the inside of the forearm, apply a couple drops of your double concentration mix to the pad of a bandaid and keep the bandage on the skin. After 48 hours remove the bandage and check for irritation.

·                        You may repeat to check for allergic sensitivity. Remember, however, that allergies can develop any time after the first exposure; thus absence of a reaction does not necessarily mean that an allergy will not develop with later exposures.

·                        If the skin under or around the bandage becomes red, swollen, itchy, or develops blisters, that is a reaction and you should avoid skin exposure to the essential oil you tested.

Bottles of oilsWhat is phototoxicity?

Phototoxicity can occur after you apply an essential oil topically and then go out into the sun. This happens most often with certain citrus oils, such as bergamot, lemon, lime, orange, and angelica.

For example, if you spray yourself with a solution of orange essential oil and then lie out in the sun or in a tanning bed, you will most likely get a sunburn or even deeper burns.


As you can see, there are safety concerns associated with improper use of essential oils. In general, however, essential oils are safe when used externally (not ingested) in low concentrations. For skin applications, that usually means concentrations no higher than 5%. For inhalation, use intermittent exposure (not more than 15 minutes in an hour). There may not be any safety information on the bottle, but usage guidelines may be posted near sales displays, on company websites, or available through company sales representatives. 

If in doubt, always consult a healthcare provider you trust who is knowledgeable about essential oils or willing to investigate with you. There is a great deal of information about essential oils available on the internet, and it may be difficult to critically determine its integrity. 

General safety recommendations include:

·                        Research each oil by reading about it in books or looking up information on the web

·                        Adhere to all cautions for not over-doing it

·                        Follow recommendations for diluting the oil

·                        Identify a knowledgeable person who can answer your questions
