Myrtle Essential Oil Benefits: 9 Research-Backed Uses & Safety

QUICK SUMMARY

Myrtle essential oil is steam-distilled from Myrtus communis, a Mediterranean evergreen traditionally used for respiratory support, skin care, cleansing, and natural healing. Its chemistry varies by source, but common constituents include 1,8-cineole, alpha-pinene, limonene, myrtenyl acetate, and related monoterpenes.

The research is strongest as a mix of human, animal, and laboratory evidence. Human studies have found benefits from myrtle-containing topical products for acne-prone skin, while animal research supports respiratory, anti-inflammatory, antioxidant, liver-protective, blood-sugar, and cardiovascular effects. Newer 2026 animal research also found that Myrtus communis essential oil reduced liver injury, oxidative stress, and triglycerides in an experimental fatty-liver model. (5, 10, 16, 18, 19)

Myrtle is not the same oil as lemon myrtle. Lemon myrtle is Backhousia citriodora, a citral-rich Australian oil with its own impressive cancer-cell research. Both oils show powerful biological activity, but the findings should not be treated as interchangeable. (13, 14)

For everyday family use, we favor inhalation and properly diluted topical application. The Liver Protecting Roll-On below is the same fennel-anise-myrtle formula we feature in The Essential Oils Apothecary; use the recipe exactly as written and follow the safety guidance in this article.

Myrtle is one of those essential oils that deserves more attention than it gets.

It has the fresh, clean respiratory character people often associate with eucalyptus, but with a softer, sweeter edge that makes it easy to use in diffuser blends, chest rubs, skin care, and everyday wellness routines. At the same time, myrtle has research that reaches well beyond breathing support, including studies on inflammation, antioxidant activity, liver protection, glucose metabolism, acne-prone skin, and cardiovascular markers.

This is also an oil where details matter. A study on isolated myrtenol is not the same thing as a study on whole myrtle essential oil. A study on Myrtus communis is not automatically evidence for lemon myrtle. And an animal or cell study can show powerful biological activity without being a human treatment trial.

So the goal here is not to water down the message. It is to show you exactly why myrtle belongs in the natural medicine cabinet, what the research actually demonstrates, and how to use it wisely.

What Is Myrtle Essential Oil?

Myrtle essential oil comes from Myrtus communis, an evergreen shrub native to the Mediterranean region, North Africa, and parts of the Middle East. For centuries, myrtle has been connected with health, beauty, peace, renewal, and ceremonial traditions. The plant produces glossy green leaves, fragrant white flowers, and dark berries, while the essential oil used in aromatherapy is most commonly produced from the leaves and other aerial plant material.

This is one of those quiet oils that doesn’t always get the spotlight, but it deserves a place in the family essential oil cabinet.

Myrtle belongs to the Myrtaceae family, the same botanical family that includes eucalyptus and tea tree. That family connection does not make the oils interchangeable, but it helps explain why respiratory support, cleansing, skin care, and antimicrobial activity show up repeatedly in traditional use and modern research.

The chemistry is where things get especially interesting. Myrtle essential oil commonly contains 1,8-cineole, alpha-pinene, limonene, myrtenyl acetate, linalool, alpha-terpineol, and related aromatic compounds. The percentages can vary substantially by geography, harvest time, plant part, and chemotype. Published analyses describe both cineole-rich and myrtenyl-acetate-rich oils. (1, 2)

That chemical variability matters because it can change aroma, potency, and biological activity. It is one more reason to buy from companies that provide botanical identity and quality testing instead of assuming every bottle labeled “myrtle” is chemically identical.

Traditionally, myrtle leaves were used in herbal teas, poultices, infusions, baths, massage oils, and beauty preparations. Today, we use myrtle essential oil in diffuser blends, chest rubs, skin care DIYs, liver-supporting roll-ons, respiratory remedies, and natural wellness routines.

Here’s the thing: essential oils work best as part of a lifestyle. Myrtle oil is not a shortcut around stewardship. It is one God-given plant tool that can support the body alongside an anti-inflammatory diet, movement, sleep, prayer, stress reduction, and reducing toxic burden in your home.

Myrtle vs. Lemon Myrtle Essential Oil

Myrtle essential oil and lemon myrtle essential oil are not the same oil.

Myrtle essential oil usually refers to Myrtus communis. It has a fresh, sweet, green, slightly medicinal aroma and is commonly used for respiratory support, skin care, liver support, and calming blends.

Lemon myrtle essential oil comes from Backhousia citriodora, an Australian tree in the same broad Myrtaceae family. It has a bold lemon aroma because it is extraordinarily rich in citral. That high-citral profile makes lemon myrtle a powerful aromatic cleanser, and it is one reason we love lemon myrtle in natural home recipes like our lemon deodorizing essential oil blend.

This distinction matters because research on lemon myrtle does not automatically apply to common myrtle.

In a 2024 breast-cancer-cell study, lemon myrtle was one of four citral-rich essential oils that strongly suppressed breast cancer cell growth. Among the tested oils, lemon myrtle produced the strongest direct antitumor effect, and its volatile fraction was less cytotoxic to normal peripheral blood mononuclear cells than the other tested oils. The researchers linked much of that activity to citral. (13)

A separate 2023 study found that lemon myrtle essential oil inhibited several cancer cell lines in vitro and induced S-phase arrest and apoptosis in HepG2 liver cancer cells. (14)

Those are bold findings, but they are lemon myrtle findings, not proof that common myrtle essential oil behaves identically.

Common myrtle has a different chemical profile and its own research on respiratory inflammation, antioxidant activity, liver protection, glucose metabolism, acne, and cardiovascular markers. Keep the botanical names straight and you will understand the research much more clearly.

9 Myrtle Essential Oil Benefits

Myrtle essential oil benefits are broad because the plant is chemically complex. Some uses are rooted in traditional herbal practice. Others are supported by human, animal, laboratory, or mechanistic research.

The key is to use the evidence boldly but honestly.

Put simply, myrtle is a respiratory-supporting, inflammation-soothing, antioxidant-rich, skin-loving oil with especially interesting research for the lungs, liver, metabolism, acne-prone skin, and cardiovascular health.

1. Respiratory Function Support

Myrtle essential oil is best known for helping support clear, easy breathing.

This makes sense when you consider its chemistry. Many myrtle oils contain substantial amounts of 1,8-cineole, the same compound that helps give eucalyptus essential oil its familiar respiratory-supporting reputation. Myrtle is generally softer and sweeter than eucalyptus, which makes it a beautiful choice in chest rubs, diffuser blends, steam inhalations, and personal inhalers.

The research is promising, but we need to distinguish whole oil from isolated constituents.

Myrtenol, a compound associated with myrtle, has been studied in multiple allergic-asthma rat models. Researchers found reductions in inflammatory cytokines, oxidative stress, inflammatory-cell infiltration, airway smooth-muscle thickening, goblet-cell changes, and other remodeling markers. In a later 2023 study, inhaled simple and niosomal myrtenol improved asthma-related lung changes in rats, with the niosomal formulation producing effects comparable with budesonide on several measured outcomes. (3, 5)

These are real anti-inflammatory and airway-remodeling effects in animal models. They are not proof that diffusing myrtle essential oil treats human asthma.

A separate study using a human bronchial epithelial cell line also reported anti-inflammatory activity from Myrtus communis essential oil under experimentally induced inflammatory conditions. (6)

Application: Add 3 to 5 drops of myrtle essential oil to a diffuser during seasonal breathing challenges. For topical use, dilute 2 drops myrtle, 2 drops eucalyptus, and 2 drops lavender in 2 tablespoons of carrier oil and massage over the chest and upper back. For more options, see our guide to essential oils for respiratory support.

2. Anti-inflammatory Effects

Myrtle essential oil helps support a healthy inflammatory response, and that is a big deal.

Inflammation is not always bad. It is part of the body’s God-designed healing process. The problem comes when inflammation becomes chronic, excessive, or poorly regulated. That is when it can contribute to pain, skin irritation, gut trouble, airway stress, cardiovascular challenges, and other inflammatory patterns.

Research on Myrtus communis and myrtenol has documented anti-inflammatory activity across several experimental systems, including airway inflammation and colitis models. In the asthma research, myrtenol lowered pro-inflammatory cytokines such as IL-1 beta and TNF-alpha while improving antioxidant defenses. (5, 7)

That does not mean myrtle oil is a cure for inflammatory bowel disease, asthma, arthritis, or any inflammatory diagnosis. It means the plant and its volatile constituents show real biological activity that may support inflammatory balance when used wisely.

This is where lifestyle matters. Myrtle oil works best when paired with the foundations: real food, clean water, daily movement, quality sleep, emotional healing, prayer, and reducing toxic burden.

Application: For sore muscles or inflamed joints, add 3 drops myrtle essential oil to 1 tablespoon carrier oil and massage into the area. You can also use it alongside other oils discussed in our essential oils for pain and inflammation guide.

3. Antioxidant Protection

Myrtle essential oil demonstrates meaningful antioxidant activity in laboratory and animal research, which helps explain why it keeps appearing in studies on the liver, skin, lungs, and cardiovascular system.

Oxidative stress happens when reactive molecules overwhelm the body’s antioxidant defenses. Over time, that can damage lipids, proteins, DNA, cell membranes, and tissues.

Myrtle essential oil has demonstrated free-radical-scavenging activity, and animal studies have found changes in tissue antioxidant systems after exposure to the oil. (2, 8, 18)

One important nuance comes from the 2022 rat study on myrtle and laurel essential oils. Myrtle showed strong antioxidant activity in many tissues, but the investigators also observed pro-oxidative effects in the kidneys and unfavorable changes in some gut bacteria at the oral dose they tested. (18)

That is exactly why “antioxidant” does not mean “the more you take, the better.” Route, dose, duration, and the individual all matter.

Reality check: you cannot out-oil a toxic lifestyle. Antioxidant-rich oils are helpful, but they are not a substitute for antioxidant-rich foods. Think berries, herbs, spices, cruciferous vegetables, green tea, citrus, and colorful plant foods.

Application: Add 1 drop myrtle essential oil to your favorite unscented body oil, massage oil, or skin care DIY. Use it in a low dilution and pair it with frankincense, lavender, carrot seed, or geranium for a skin-supporting antioxidant blend.

4. Liver Support

Myrtle has a long traditional reputation as a digestive and liver-supporting plant, and its essential oil has direct animal research behind that use.

In a carbon-tetrachloride model of acute liver injury, myrtle essential oil pretreatment improved liver enzymes, lipid markers, oxidative-stress measures, and tissue changes in rats. (10)

The research has continued.

A 2026 animal study evaluated Myrtus communis essential oil in rats exposed to bisphenol A to induce metabolic dysfunction-associated fatty liver disease. The oil improved liver and lipid markers in a dose-dependent manner. At the highest tested dose, plasma triglycerides fell by about 52% compared with the BPA-only group, hepatic malondialdehyde fell by about 84%, and liver histology showed less steatosis and cellular damage. (19)

That is powerful liver-protective research.

It is still preclinical. These were orally dosed animal models, not human trials of a topical roll-on.

The liver is one of the body’s hardest-working organs. It processes hormones, alcohol, medications, metabolic waste, and environmental chemicals. Supporting your liver means supporting your whole body.

Application: Use the Liver Protecting Roll-On below over the upper right abdomen once daily for up to one month. For broader liver support, consider pairing essential oils with food-based strategies, castor oil packs, hydration, cruciferous vegetables, and gentle daily movement. Learn more about castor oil benefits for natural wellness routines.

5. Blood Sugar Regulation

Myrtle has been used traditionally as a hypoglycemic plant, and animal research gives that reputation real scientific support.

In a 2004 study, myrtle volatile oil significantly lowered blood glucose in alloxan-diabetic rabbits at the effective tested dose and mildly reduced triglycerides. The oil did not significantly lower glucose in normal rabbits, and the investigators proposed mechanisms involving intestinal alpha-glucosidase, glycolysis, and glycogen formation rather than increased insulin secretion. (11)

Myrtle also appeared in one of the essential-oil combinations tested by Georgetown University researchers in insulin-resistant and hypertensive rats. The blends were given orally in carrier oils, and all three formulations improved measures related to insulin sensitivity and systolic blood pressure. A blend containing oregano, cinnamon, fenugreek, cumin, and myrtle produced especially strong glucose-related results. (20)

That blend research is the basis for the Blood Sugar-Balancing formulas we have taught in our books and programs.

This is important, but we need to say it clearly: myrtle essential oil is not a replacement for diabetes medication, blood sugar monitoring, your physician’s guidance, nutrition, exercise, or metabolic testing.

Application: For general wellness, diffuse myrtle during meal prep or use a properly diluted topical blend on the bottoms of the feet. Myrtle is also a featured oil in our high blood sugar essential oil blend. If you take blood sugar medication, use essential oils therapeutically only with appropriate guidance.

6. Cancer-Fighting Research

This is one of the most fascinating areas of myrtle-family research.

Lemon myrtle essential oil, which is different from common myrtle, has shown strong antitumor effects in cell research.

In the 2024 breast-cancer study discussed above, lemon myrtle essential oil inhibited the growth and invasion of breast cancer cells, including activity from its volatile components at more than 500-fold dilution. Lemon myrtle produced the strongest direct antitumor effect among the four citral-rich oils studied, and the researchers identified citral as a major active driver. (13)

A 2023 study found that lemon myrtle essential oil was cytotoxic to liver, neuroblastoma, colon, and non-small-cell lung cancer cell lines and induced S-phase arrest and apoptosis in HepG2 cells. (14)

Common myrtle has its own preclinical anticancer literature involving extracts, essential oil, and isolated plant compounds. Reviews describe antiproliferative, apoptosis-related, antioxidant, and antimutagenic activity across experimental models. (1, 15)

This is bold research, and we should not water it down. These studies demonstrate cancer-fighting, antitumor, cytotoxic, and antiproliferative activity in laboratory and preclinical settings.

But the evidence boundary is equally clear: neither common myrtle essential oil nor lemon myrtle essential oil has been proven in human clinical trials to treat cancer.

Application: For cancer-care support, focus first on reducing toxic burden, improving nutrition, sleep, prayer support, stress relief, and safe supportive essential oil use. Read more in our article on the truth about essential oils for cancer treatment.

7. Skin Care, Acne, and Blemish Control

Myrtle essential oil is a beautiful skin-supporting oil, especially for oily, blemish-prone, or irritated skin.

And unlike several benefits in this article, this one has direct human research.

In a 2018 clinical study of 20 Korean women with acne-prone skin, the group using myrtle-containing skin-care products for six weeks had significant improvements in acne grade, pore measures, sebum, desquamation, and microorganism measurements compared with the control group. The authors specifically identified steam-distilled myrtle essential oil as the test material used in the myrtle preparations. (16)

The study was small and used a complete myrtle-containing skin-care regimen rather than a single drop of pure oil as a stand-alone treatment, but it gives us human evidence that is much stronger than simply saying myrtle “might” be good for blemishes.

Other human trials using topical Myrtus communis preparations have also reported improvement in acne measures, adding to the clinical interest around this plant. (17)

Myrtle blends well with tea tree, lavender, frankincense, geranium, sandalwood, rosemary, and orange for acne-prone skin. Just remember that facial skin is delicate. More oil does not mean better results.

Application: Add 1 drop myrtle essential oil to 1 tablespoon jojoba oil or another carrier oil and apply sparingly to blemish-prone areas. Or add myrtle to Mama Z’s DIY facial cleanser. For more options, see our guide to essential oils for acne.

8. Synergistic Blending Support

Myrtle is a wonderful blending oil because it bridges several categories at once: respiratory, skin, immune support, emotional wellness, and cleansing.

For respiratory blends, it pairs well with eucalyptus, rosemary, peppermint, frankincense, pine, cypress, and lavender. For skin blends, it pairs well with tea tree, geranium, lavender, frankincense, sandalwood, and carrot seed. For calming blends, it pairs beautifully with lavender, Roman chamomile, bergamot, orange, cedarwood, and frankincense.

This matters because essential oils often work best in thoughtful combinations. You are not just chasing one “magic” oil. You are building a blend around a purpose.

We have seen this principle in research as well. The blood-sugar study above did not isolate myrtle; it tested multi-oil formulas and found measurable metabolic effects from the blends. That does not prove every blend is automatically stronger, but it illustrates why formulation matters. (20)

Myrtle’s fresh, soft, herbal aroma can also help round out stronger oils. It can make eucalyptus blends smell gentler, tea tree blends smell more pleasant, and liver-supporting oils like fennel and anise feel more balanced.

Application: Try this simple respiratory diffuser blend: 3 drops myrtle, 2 drops eucalyptus, 2 drops lavender, and 1 drop frankincense. For more inspiration, explore our essential oil diffuser recipes.

9. Heart Health

Myrtle essential oil may also support cardiovascular health through antioxidant, lipid, and metabolic pathways.

In a 2022 rat study, oral myrtle essential oil reduced cholesterol, triglycerides, LDL cholesterol, VLDL cholesterol, and several atherogenic indicators over two weeks. The oil also showed strong antioxidant effects in multiple tissues. (18)

Those are meaningful cardiovascular findings, but the same study also reported kidney pro-oxidative effects and changes in intestinal bacteria that were not uniformly favorable.

So I would not take an oral animal dose and turn it into a casual human internal-use recommendation.

What the study does show is that myrtle essential oil can influence lipid metabolism, oxidative balance, and cardiovascular risk markers in a living system. That belongs in the conversation when we talk about whole-body heart health.

From a Biblical health perspective, heart health is not just physical. Stress, fear, bitterness, hurry, poor sleep, and emotional overload all affect the body. Essential oils can be a helpful cue to slow down, breathe deeply, pray, and steward the body with wisdom.

Application: Add 2 drops myrtle essential oil to 1 tablespoon sweet almond, jojoba, or olive oil and massage over the chest, shoulders, or pulse points during a calming evening routine. You can also use it alongside our essential oils for heart health recommendations.

Liver Protecting Roll-On Recipe with Myrtle Essential Oil

This is the Liver Protecting Roll-On we feature in The Essential Oils Apothecary, and the formula stays exactly as published.

The blend is built around fennel and anise, two oils rich in anethole, with myrtle added as part of the liver-support strategy. Anethole has been studied for anti-inflammatory, antioxidant, hepatoprotective, and cancer-related biological activity, while myrtle essential oil has direct animal research showing protection against chemically induced liver injury. (10)

Use this over the liver area, which is the upper right-hand portion of the abdominal cavity. Because this is a concentrated topical blend, use it as directed, avoid sensitive skin, and do not use it with children, during pregnancy, while nursing, or with liver disease or medication use unless you have professional guidance.

How to Use Myrtle Essential Oil Safely

Myrtle essential oil can be used through inhalation and topical application when properly diluted.

For inhalation, add myrtle to a diffuser, personal inhaler, tissue, cotton ball, aromatherapy necklace, or steam bowl. This is often our first choice for breathing support, emotional balance, and aromatic cleansing.

For topical application, dilute myrtle essential oil in a carrier oil before applying it to the skin. Good carrier oils include jojoba, fractionated coconut oil, sweet almond oil, olive oil, avocado oil, and castor oil.

Carrier oils do more than simply make an essential oil weaker. They dilute and disperse essential oils, reduce evaporation, improve topical safety, help the oils spread over the skin, support penetration, and can amplify therapeutic effects by keeping the volatile compounds in contact with the skin longer.

Myrtle works well in chest rubs, massage oils, facial oils, roll-ons, skin care recipes, and respiratory blends.

Do not apply myrtle essential oil directly to the skin undiluted. Avoid the eyes, inner ears, mucous membranes, and broken or irritated skin. Patch test before using it on sensitive skin.

Because myrtle can contain substantial 1,8-cineole, be cautious with young children and avoid applying it near the face of babies or toddlers. If you are pregnant, nursing, using essential oils with children, taking medications, dealing with asthma, managing diabetes, navigating liver disease, or under medical care, use condition-specific therapeutic protocols with appropriate guidance.

The animal research also gives us a reason not to assume that internal use is automatically better. Oral myrtle essential oil affected glucose, lipids, liver markers, kidneys, and gut bacteria in animal studies. That tells us the oil is biologically active enough to deserve respect. (11, 18, 19)

Also choose quality. A beautiful oil can only be as good as its sourcing, distillation, storage, and testing. For help choosing wisely, see our guide on where to buy essential oils.

Myrtle Essential Oil FAQs

What is myrtle essential oil used for?

Myrtle essential oil is commonly used for respiratory support, diffuser blends, chest rubs, skin care, acne-prone skin, massage oils, liver-supporting roll-ons, emotional wellness, natural cleansing, and antioxidant support. Human acne research and preclinical respiratory, anti-inflammatory, hepatoprotective, metabolic, and cardiovascular studies give several of these uses real research support. (5, 10, 16, 18)

What does myrtle essential oil smell like?

Myrtle has a fresh, green, slightly sweet, herbaceous aroma with soft medicinal notes. It is often gentler and sweeter than eucalyptus, which makes it easy to blend into respiratory, skin care, and calming formulas.

Is myrtle essential oil good for breathing?

Yes, myrtle is one of our favorite respiratory-supporting essential oils. Its 1,8-cineole-rich chemistry and the anti-inflammatory research on myrtenol support its use in diffuser blends, steam inhalations, and diluted chest rubs. The strongest airway research is still preclinical, so do not use myrtle to replace prescribed asthma or respiratory treatment. (3, 5, 6)

Is myrtle the same as lemon myrtle?

No. Myrtle essential oil usually comes from Myrtus communis, while lemon myrtle essential oil comes from Backhousia citriodora. Lemon myrtle is much higher in citral and has a strong lemon aroma. Myrtle is more herbaceous, fresh, and commonly rich in 1,8-cineole, alpha-pinene, and myrtenyl acetate.

Can myrtle essential oil help with acne?

Human research is encouraging. A small 2018 clinical study using myrtle-essential-oil-containing skin-care products reported significant improvements in acne grade, sebum, pores, desquamation, and microbial measurements over six weeks. Use myrtle diluted because facial skin can be sensitive. (16)

Can myrtle essential oil support the liver?

Animal research says yes. Myrtus communis essential oil has reduced oxidative stress and liver injury in toxin-induced models, including a 2026 rat study of experimental metabolic fatty liver disease. These findings support our liver-use recommendation, but they are not a human liver-disease treatment trial. (10, 19)

Can I ingest essential oils?

Do not casually ingest essential oils in water or neat (undiluted). Internal use of essential oils requires proper dilution, product quality, dosing knowledge, and safety guidance. Learn more about how to ingest essential oils here.

For myrtle specifically, our everyday family recommendations in this article focus on inhalation and diluted topical application. The oral research cited here used defined animal doses that should not be converted into a DIY human protocol.

What oils blend well with myrtle essential oil?

Myrtle blends well with eucalyptus, rosemary, peppermint, lavender, frankincense, tea tree, lemon, orange, bergamot, cypress, pine, cedarwood, fennel, anise, geranium, sandalwood, and Roman chamomile.

Who should avoid myrtle essential oil?

Use extra care with pregnancy, nursing, young children, asthma, diabetes medication, liver disease, complex medication regimens, active cancer treatment, and fragrance sensitivity. Avoid undiluted topical use and keep it away from the eyes and mucous membranes. Condition-specific therapeutic use should be individualized rather than automatically banned.
