Essential Oils to Avoid

Essential Oils To Avoid Dangerous

Essential oils affect the body in two ways. When applied to the skin, they penetrate through the follicles and sweat glands and are then absorbed into the body's fluids. Once inside the body, they have many beneficial effects including:

  • Stimulating the immune system and strengthening against attack
  • Speeding up the elimination of toxins
  • Promoting new cell growth
  • Stimulating digestion
  • Stimulating blood circulation
  • Promoting the body's natural healing processes.
Essential oils also enter the body through inhalation. The microscopic molecules are absorbed into the blood stream as the lungs oxygenate the blood. This makes them excellent for use in baths, vaporizers and even on candles.Aromatherapy also works on an emotional level, helping to calm and sooth the nerves and to promote a healthy sense of balance between the mind and body.

Essential Oils to Avoid

Certain essential oils should only be used by a qualified practitioner, and even then there are some that still should be avoided. Here is a list of essential oils to steer clear of and when to avoid them:

Diabetes - diabetics should avoid angelica

Epilepsy - because certain essential oils may over stimulate the nervous system, people with epilepsy should avoid fennel, rosemary and sage.

Hypertension - people suffering from high blood pressure should avoid hyssop, rosemary, all types of sage and thyme.

Pregnancy - due to the possible effects of essential oils on the growing child and also the uterine muscles, always consult and experienced aromatherapist before using essential oils during pregnancy. Nevertheless there are some oils that should be completely avoided. These include: Basil, laurel, angelica, thyme, cumin, aniseed, citronella and juniper.

Sensitive skin - people with very sensitive skin should avoid basil, laurel, coriander, tea tree, Neroli, geranium, mint, yarrow, Roman and German chamomile, lemon balm, citronella, ginger, hops, jasmine, lemon, lemongrass, (unless greatly diluted with a carrier oil), , turmeric and valerian. Conduct a skin patch test on a very small area on the inside of your wrist if you are uncertain of allergic reaction. If you notice any irritation, discontinue using the oil.

Toxicity - because of their strength and the chance of problems through regular prolonged use, several essential oils should not be used for longer than two weeks at a time. These include cinnamon, turmeric, valerian, laurel, juniper, aniseed, laurel, coriander, eucalyptus and juniper.

Dangerous oils - oils you avoid at all costs include bitter almond, red thyme, common sage, rue, wormwood, tansy, savory, wintergreen and sassafras. These oils can cause poisoning.

Sue - 21-Dec-17 @ 5:53 PM
Can I use WHITE Angelica as a diabetic? I know the book says not to use Angelica, but my book is missing information for White Angelica, so I can't tell if it's safe for me to use. Any help is appreciated.

I have high blood pressure and love Eucalyptus oil. Are fragrance aromatherapyscents that are concentrated just as bad for HBP. Also if I diluted so call pure with water and use it as a room spray, does that help

Pure essential oils are consideredmedicine and must be use with care. Apply them diluted sparingly with education and care. As a remedy maker ,i have seen the wonders of healing through plant as i so fondly call it. A worthwhile investment * A household basic oils per month Lavender, Peppermint oil, Sweet Orange Oil Ylang Ylang Oil Lemongrass Oil Carrier oil: VirginCoconut /remedy well and beneficial as a supplement.*value buy These are essentials that tailors the entire household ailments and is safe to use with out worrying about this and that. I do believe that alternative methods through essential oils complements conventional methods of healing. Keep track on allergies and use in moderation all be good. Do not go after heresay but education is bliss. Start readingjournals of wellness from reputable sources. Go green &create a chemical free zone in your own space.. I am mother of five andenjoying a daily useof essential oils with my family and as a career.Its a way of life!? Buy only from reputable sources ,like Young Living or Doterra ,they make you feel healthy !??

Peppermint is fine for epileptics.I've looked it up because I personally have been Epileptic for 47 years.I had to make sure before I used it for my migraines to make sure it would effect me.Eucalyptus is to AVOID which you probably know. I hope you didn't take this being mean but I personally haven't had any problems with peppermint.It has helped me with my migraines unbelievably also.

Some essential oils that are to be avoided for HIGH BLOOD PRESSURE are also needed to be avoided for EPILEPSY.
Della - 2-Feb-17 @ 5:22 AM
I have had epilepsy since 2006 and have been seizure free for now 5 years. I have used Sage, Eucalyptus and Peppermint (all have been said to be avoided) and have never had an issue.

Marta - First, don't believe everything you read! God has given us these oils to be used for good.I purchased one of the doTerra starter kits and an EO book and love them! You need to educate yourself. I also might suggest that you connect with an EO group and an EO consultant. I'm so glad I have made this investment versus OTC crap or doctor prescriptions. They have helped my family tremendously! Please reconsider before getting rid of them or putting them in storage. FOR HBP I am using a roller bottle with the following recipe:30 drops Ylang Ylang 15 drops Cypress 15 drops Marjoram 15 drops Rosemary (optional – if high blood pressure is due to stress) 15 drops Frankincense Twice a day, roll some into the sole of the left foot, right below the big toe.Also roll some below the ring finger of your left hand and over your heart.These are commonly referred to as the “reflex points” for the heart.

Recenyly I started using essential oils, joined largest online group and became a member of doTerra. I bought a substantial book on EO and read a lot, starting to build my collection. Now I'm reading online and there are so many conflicting posts about oils bad for some medical issues, different from each other and from books, it's making me think I shouldn't have even started with them, very scary. We hear about an oil excellent for an ailment, no contraindications on the books, buy it and then on another post online it's on a list against something else. Have I wasted almost $1000 on oils, books, storage, etc? Very scary.

OilyGirl - Your Question:
I recently purchased white Angelica for numerous reasons, but one being because it's touted to 'help' (or at least not cause issues for) people with high blood pressure. When I got it home, before using it I read the bottle and noticed hyssop as the ingredient. Which is a known 'no no' for high BP. So now I'm worried to use it in my house for fear of my HBP mother having an issue. Should I just refrain from this then? Thanks for the help

Our Response:
We can't advise on specific individuals but if there is an ingredient that you know is one to avoid if you have high blood pressure, then it makes sense not to take it.

Just wonder if there is evidence for your "do not use" list

Mint and eucalyptus increase blood pressure and should be avoided by persons with hypertension.

My daughter has cerebal palsy and suffers from epilepsy. I was wondering if a citronella wristband could cause her to have a seizure if worn for long periods? Please advise.
Mick - 23-Jan-14 @ 7:30 AM
Which 6 essential oils are used in connection with high blood pressure? Lavender oil comes to mind. It was one of the first of the essential oils to be recognised by French fragrance chemist Rene Maurice Gattefosse as being therapeutic, which led to his research of Aromatherapy in the first place, and aromas of lavender and chamomile (calmative and anti-inflammatory) oil were discovered by the research team at Yale University to be the most beneficial of the essential oils to reduce blood pressure by their relaxing and calming effects. Other oils and their acclaimed therapeutic properties that are used are Orange oil (mood enhancer), Geranium oil (a relaxant), Lemon (relieves anxiety), Clary sage (calming sedative), Marjoram (balances emotions), Cyprus and Peppermint. A wonderful career you have chosen hope all goes well for you.

My profoundly handicapped son likes the smell of karvol on his pillow when he gets a cold.Because of this we decided to purchase a vaporiser and purchased eucalyptus oil. I was then told you shouldn't use eucalyptus oil when you have epilepsy. What do you suggest I do?
Joking - 3-Mar-13 @ 7:55 PM
Having recently qualified as an Aromatherapist I am still wary of suggesting oils to people who have certain ailments but want to try Essential oils. Recently I was asked what oils could be used for high blood pressure? Now I recommended Clary Sage & lavender, but looking at the list above of what oils to avoid, it says not to use any sage oils for high blood pressure!!!Now I am confused. Can you please advise me Many thanks
