About Essential Wintergreen Oil

Pain and inflammation relief

The active ingredient in wintergreen oil, methyl salicylate, is closely related to aspirin and has analgesic and anti-inflammatory properties. As such, products containing wintergreen oil are often used as an anti-inflammatory and topical pain reliever.

Wintergreen oil has also been used in traditional medicine for the following conditions:

Insecticide

Wintergreen oil may also be found in insecticides and repellents. However, research suggests that, when compared to other essential oils, it may be more effective as an insecticide or fumigant than as a repellent.Zhang Q, et al. (2016). Primary screening of plant essential oils as insecticides, fumigants, and repellents against the health pest Paederus fuscipes (Coleoptera: Staphylinidae). DOI:

Flavoring and scents

In industry and manufacturing, wintergreen oil is used as a flavoring agent for products such as candies, toothpastes, and mouthwashes. It can also be used as a scent additive.

Many of the stated benefits or uses of wintergreen oil are derived from anecdotal evidence, meaning they’re heavily based off personal testimony.

There’s limited research on the potential health benefits of wintergreen oil and its active ingredient, methyl salicylate. But what does the research tell us so far?

The benefits for pain are mixed

The research into wintergreen oil or methyl salicylate as a topical pain reliever has shown mixed results, although wintergreen oil has been suggested as a potential alternative treatment for easing lower back pain.Hebert PR, et al. (2014). Treatment of low back pain: The potential clinical and public health benefits of topical herbal remedies.

Times it worked

One 2010 study in adults with muscle strain found that application of a skin patch containing methyl salicylate and menthol provided a significant amount of pain relief compared to the placebo patch.Higashi Y, et al. (2010). Efficacy and safety profile of a topical methyl salicylate and menthol patch in adult patients with mild to moderate muscle strain: A randomized, double-blind, parallel-group, placebo-controlled, multicenter study. DOI:

Additionally, a case study from 2012 found that topical application of methyl salicylate provided headache relief to an individual who had severe headaches following electroconvulsive therapy.Logan CJ, et al. (2012). Treatment of post-electroconvulsive therapy headache with topical methyl salicylate. DOI:
10.1097/YCT.0b013e318245c640

Times it didn’t

A review of several clinical trials of topical salicylates, one of which included methyl salicylate, didn’t find support for their use for musculoskeletal pain.Derry S, et al. (2014). Salicylate-containing rubefacients for acute and chronic musculoskeletal pain in adults. DOI:
10.1002/14651858.CD007403.pub3 The authors indicated that larger, better quality trials need to be performed to assess efficacy.

Wintergreen oil has worked against some bacteria

A 2017 study found that 0.5 percent wintergreen oil had a similar or higher antibacterial activity than a control antibiotic against persistent forms of Borrelia burgdorferi, the causative agent of Lyme disease.Feng J, et al. (2017). Selective essential oils from spice or culinary herbs have high activity against stationary phase and biofilm Borrelia burgdorferi. DOI:
10.3389/fmed.2017.00169

The antibacterial effect was diminished or absent at lower concentrations, however.

Other studies on Neisseria gonorrhoeae and a Streptococcus species observed no antibacterial activity for wintergreen oil.Cybulska P, et al. (2011). Extracts of Canadian first nations medicinal plants, used as natural products, inhibit Neisseria gonorrhoeae with different antibiotic resistance profiles. DOI:
10.1097/OLQ.0b013e31820cb166 Chaudhari LK, et al. (2012). Antimicrobial activity of commercially available essential oils against Streptococcus mutans.

Wintergreen oil works in dental products

In 2013, a subcommittee of the Food and Drug Administration reviewed methyl salicylate used in over-the-counter dental products that control plaque and gingivitis.Oral health care drug products for over-the-counter human use; antigingivitis/antiplaque drug products; establishment of a monograph; proposed rules. (2003).
fda.gov/downloads/Drugs/DevelopmentApprovalProcess/DevelopmentResources/Over-the-CounterOTCDrugs/StatusofOTCRulemakings/UCM096081.pdf Examples of such products include mouth rinses, mouthwashes, and sprays.

The subcommittee concluded that methyl salicylate used at a set concentration either by itself or combined with eucalyptol, menthol, and thymol is both safe and effective in these products.

Wintergreen oil should never be swallowed.

Methyl salicylate, the active ingredient in wintergreen oil, can be toxic, so care should always be taken when using wintergreen oil.

Particular care should be taken around children, who may be attracted to wintergreen oil by its scent. Wintergreen oil should never be used on children and should always be kept in a childproof bottle, out of reach of children.

Wintergreen can be very dangerous and even fatal if swallowed. In fact, a single teaspoon of methyl salicylate is roughly equivalent to 90 baby aspirin tablets.Seneviratne MP, et al. (2015). Accidental methyl salicylate poisoning in two adults. DOI:
10.4038/cmj.v60i2.8154

Because methyl salicylate is absorbed through the skin, a negative reaction can also happen when it’s applied topically. Never apply any essential oil to the skin without diluting it in a carrier oil first.

One 2002 case study reported acute toxicity in a man receiving a topical methyl salicylate treatment for psoriasis.Bell AJ, et al. (2002). Acute methyl salicylate toxicity complicating herbal skin treatment for psoriasis.

Interacts with warfarin

Wintergreen oil or methyl salicylate can also exacerbate the effects of anticoagulant drugs, such as warfarin. This can cause bleeding or hemorrhaging.

Individuals who are taking blood-thinning drugs or who have bleeding disorders, such as hemophilia, should not use wintergreen oil.

Due to the fact that it can be absorbed through the skin, women who are pregnant or breastfeeding should never use wintergreen oil.

Aspirin allergy

Since methyl salicylate is so similar to aspirin and other salicylates, people who are sensitive to salicylates shouldn’t use wintergreen oil.

Remember that wintergreen oil should always be used externally. It’s a very strong essential oil and can be absorbed through the skin, so it should never be applied undiluted.

Essential oils should be diluted in a carrier substance, which can include oils such as grapeseed and jojoba. Always be sure to follow appropriate dilution guidelines.

When making a solution with wintergreen oil, it should only make up 2 to 3 percent of the final solution volume, according to the New York Institute of Aromatic Studies.

For a 2.5 percent dilution, try mixing 15 drops of wintergreen essential oil with 6 teaspoons (1 fluid ounce) of carrier oil.

If you choose to make a solution with wintergreen oil and other essential oils, wintergreen oil may blend well with peppermint, lavender, and eucalyptus oils.

Due to the potential for toxicity when ingested and limited evidence of its efficacy in aromatherapy, wintergreen oil isn’t recommended for use in aromatherapy, such as in a room diffuser.

The active ingredient in wintergreen oil, methyl salicylate, is often chemically synthesized. In many cases, the name “wintergreen oil” can be used interchangeably with synthetic methyl salicylate.

So how can you make sure that you select high quality, plant-derived wintergreen oil? Follow these tips:

1. Check for the Latin name of the plant. This can help you verify that you’re selecting the specific essential oil you what.
2. Look for information about purity. Some essential oils are mixed with other things and may not be 100 percent pure.
3. Evaluate the price. If it seems really cheap compared to other products, it may not be the real deal.
4. Give it a smell. Does it smell like you expect it to? If not, don’t buy it.

Wintergreen oil is an essential oil that’s traditionally derived from the leaves of the wintergreen plant. Methyl salicylate, the active ingredient of wintergreen oil, can be chemically synthesized and is often referred to as wintergreen oil in many products.

Over the years, wintergreen oil has been used for a variety of health-related purposes, including for aches and pains, inflammation, and tooth decay.

Many of the benefits of wintergreen oil are currently based off anecdotal evidence. More research needs to be performed in order to assess the health benefits of this essential oil.
