Salicylate Sensitivities and Essential Oils: What you need to know!

A common question I am asked is whether people need to avoid all essential oils if they have a salicylate sensitivity (SS). A number of blogs and websites include essential oils as something to avoid with SS, and many of these advocate avoiding essential oils completely. Hopefully, this post will help clear up the confusion and misinformation that is so widely spread on the internet.

What are salicylates and where are they found?

Salicylates are naturally occurring compounds found in many plants, foods (nectarine, kiwi, blackberries, blueberries, asparagus, carrots, celery), spices (black cumin, paprika, thyme), herbs, medications (pain relievers, both topical and oral), fragrances, and other products. Plants produce salicylates to protect them against predators and diseases.

What is a salicylate sensitivity or salicylate intolerance?

Most people can handle the amounts of salicylates found in foods and other products without any adverse effects. It typically takes very large doses of salicylates to harm the average person. However, for those with a sensitivity or intolerance to salicylates, even a small amount can cause a severe reaction. These effects can be cumulative, meaning that a salicylate sensitive person may be able to tolerate small amounts of salicylates, but over time this build-up causes symptoms from excessive exposure. It is believed that only a small portion of the population is sensitive to salicylates, but some people with co-occurring conditions may be more likely to experience this unpleasant condition.

  • Children with ADD/ADHD (2)
  • People who experience migraines, headaches, or itchy rashes from certain foods (3)
  • People with irritable bowel syndrome (3)

What essential oils have salicylates?

As reported in Evidence-Based Essential Oil Therapy, both birch and wintergreen contain significant amounts of methyl salicylate (a compound similar to aspirin), usually over 95%. These essential oils should obviously be avoided through any method of administration by those with SS. In addition, a few other essential oils have from 0.5% to 15% methyl salicylate: ylang ylang from Madagascar (I and II), clove bud, and clove stem essential oils. These essential oils should be used cautiously or not at all by people with SS. The same would go for any blends that contain high salicylate essential oils.

The takeaway 

As you can see, only a handful of essential oils contain enough methyl salicylate to be of concern. It is irresponsible to contraindicate all essential oils and forbid people with SS the opportunity to benefit from EOs just because of a few outliers that contain appreciable levels of salicylates. Those with SS should carefully read product labels (looking for the offending essential oils) to determine if they should use products that contain essential oils.

    My husband reacts to any essential oil I give him whether used internally or externally. This is the first time I have seen something that might give us a clue to why. We are continually told there is not allergy to EOs. But time and time again, he reacts with blisters, redness, swelling, infections, chapping, etc.

      It could be the carrier oil they are using as well. If you are reactive it could mean you were sensitive to something in the ethanol. I’m msc with a mast cell disorder, and react to plant oils of many kinds as well as more of the carriers, sals and a list of other things. Google corn allergens list if you want to get an idea how hard it can be to associate triggers. A food journal that includes personal and cleaning products plus symptoms including moods is invaluable. Some reactions are delayed and it can be hard to find triggers without one.

    Thank you so much for this post. I have IBS and (more than likely) salicylate sensitivity – although histamines are also an issue. I’ve just started using Tea Tree cleanser on my face which is helping my acne significantly. Just wondering, do you know what percentage of methyl salicylate Tea Tree oil has? I’ve been fine using it so far but then today I foolishly burnt some incense and reacted to it with a hot face and belly rash.

    Tea tree oil was the first oil I reacted to years ago(skin rash). Prior to that I had an allergic reaction to Aspirin. And all my life I’ve reacted to gluten. Suddenly in my 40’s I’ve become sensitive to almost everything. Thankfully, discovering what salicylate sensitivity is, has helped me figure out a lot and I can maintain an acceptable balance in my life. Each food, plant or chemical gives a different reaction so it becomes very confusing and hard to track. I agree with Diana, my journal helps me to narrow down suspects so that I have fewer bouts. Then it just becomes a way of life. The mental aspect is challenging as reactions affect your mood and one can feel isolated and frustrated. With practice, it’s possible to rise above, let go and still feel in harmony with the world. A reaction will blow over, so I now try to accept it rather than continuing down that path of hopelessness.

      Hi Jan I totally understand how you feel I feel like I react to a many things often it’s the healthy things that trigger me with histamine, salicylates, oxylates etc I have found out I have mthfr a genetic methylation issue and I think pregnancy may have triggered my downward spiral. Try nettle tea, to toxaprevent and a clean diet with some chocolate and try not to be anxious about it

    Hello, I am a Clilnical Aromatherapist, trying oh so hard to make a Natural Moisturiser for my Salicylate Free friends and customers, I have made one, however it lacks any essential oil. I was very interested to read your item. I cant see any table or list within your article with percentages of methyl salicylate in Essential Oils. Are you aware of one?

    My customers would be very very wary of trying a bar with any essential oils in them. I am also limited to carrier oils to use. Any other information you could provide would help me greatly.

    I would love to put your post out on my Anderson Aromatics Website Blog, if that would be acceptable to you?

        I’ve read all through appendix G of your book, and there is nothing specifically outlining essential oils containing 0.5% salicylates in there. I have to avoid all salicylates due to drug interaction with Guaifenesin for my fibromyalgia. In your research, have you found instances of essential oils with extremely low levels of salicylates? I have an extensive EO collection (well over 200 different oils), so I’m pretty devastated to read that I cannot use any of them. Like the original poster, I am very interested in seeing a chart outlining actual percentages for others that cannot tolerate even moderate levels of salicylates. Can you point us in the right direction, since it is not specifically listed in your book?

          It is Appendix G of “Medicinal Essential Oils” that has this information. However, it does not include EOs with less than 0.5% salicylates. Very few oils have salicylates but the only way to avoid them completely would be to have a complete GC-MS of each oil you intend to use.
