16 Proven Benefits Of Rosemary Oil

bRosemary oil is a popular essential oil known for its wide array of health benefits. It has become increasingly popular over the years for its ability to stimulate hair growth, boost mental health, relieve respiratory problems, and reduce pain.

What is Rosemary Essential Oil?

Rosemary oil is extracted from the popular herb Rosmarinus officinalis. It is very popular in the Mediterranean region as a culinary herb. The rosemary bush belongs to the mint family, which includes basillavenderpeppermint, and sage.

Rosemary has been extensively used since ancient times for a variety of purposes. The Romans gave special importance to the rosemary plant and used it frequently in religious ceremonies. It was also used during wedding ceremonies, food preparations, cosmetics, and medicinal herbal products. Rosemary plant and its extracts were used by the ancient Egyptian civilization as incense.

The health benefits of rosemary essential oil made it a favorite of Paracelsus, a renowned German-Swiss physician, and botanist, who made significant contributions to the understanding of herbal medicine during the 16th century. Paracelsus valued rosemary essential oil because of its ability to strengthen the entire body. He correctly believed that rosemary oil had the ability to heal delicate organs such as the liver, brain, and heart.


Health Benefits of Rosemary Oil

Today, many medicinal preparations contain rosemary essential oil and its well-researched health benefits are listed below:

Aids in Digestion

Rosemary oil is often used for curing indigestion, relieving flatulence, stomach cramps, constipation, and bloating. This essential oil is also thought to relieve symptoms of dyspepsia and is an appetite stimulant, states a 2015 report published in the Asian Pacific Journal of Tropical Biomedicine.[1]

Detoxifies the body

Research has shown that rosemary essential oil detoxifies the liver, whilst helping in the regulation, creation, and release of bile, which is a key part of the digestive process.[2]

A team of researchers from Libya published a report in the Indian Journal of Experimental Biology, that gave empirical evidence to show that rosemary oil helps in increasing the volume of secretion of bile from the liver and prevents damage to the vital organ. The researchers conducted an experiment, in which they used freeze-dried ethanol and liquid extracts of young sprouts of rosemary to protect rats against chemical-driven liver damage. It was discovered that by feeding rats rosemary sprouts, there was a significant increase in their bile flow, and, also a drastic improvement in their liver conditions

The results of an animal study led by Aleksandar Raskovic, et al. showed that rosemary essential oil exhibits antioxidant properties participate in eliminating free radicals from the body, and also helps protect the liver against damage.[3]

Hair Care

Many people use rosemary oil and rosemary teas for hair care in shampoos and lotions. The Colomer Group Spain, S.L. a subsidiary of Revlon Consumer Products Corp has received a patent[4] for using rosemary extracts in hair lotion for the treatment of hair loss and stimulating hair growth. Regular use of rosemary oil helps stimulate follicles, making hair grow longer and stronger. It is also believed that this oil slows down premature hair loss and graying of the hair.According to a report in theSkin Med Journal, by a group of researchers from Iran led by Dr. Panahi Y, a research scholar from the University of Medical Sciences, Iran, rosemary oil helps to treat androgenetic alopecia.[5] The study aimed to investigate the clinical efficacy of rosemary oil in the treatment of androgenetic alopecia as against mini doxie. After administering rosemary oil to the patients suffering from alopecia, for a period of six months, it was noted that there was a significant increase in their hair count. It was thus concluded that rosemary oil is an excellent tonic for bald people or for those who are beginning to show signs of male pattern baldness.

Rosemary essential oil is also beneficial for dry and flaky scalps. Regular massaging of the scalp with rosemary oil nourishes the scalp and removes dandruff. Furthermore, it is often mixed with tea tree oil and basil oil to alternately treat scalp problems. For many years, Rosemary has been combined with olive oil as a way to darken and strengthen hair by using hot oil treatments.

Oral Care

Dr. Alexandra Meier et.al published a report on the antimicrobial activity of essential oils and essential oil components towards oral bacteria in the Molecular Oral Microbiology journal in which it is stated that most essential oils are used as a disinfectant and a mouthwash.[6]Rosemary has been found to be useful in removing bad breath or halitosis according to a research study conducted by Sanae Akkaoui, et al.[7] By removingoral bacteria, rosemary essential oil may help prevent gingivitis, cavities, plaque build-up, and other damaging dental conditions. However, more scientific evidence and studies are required to support this claim.

Skin Care

A study led by Dr. Lucia Montenegro, Department of Drug Sciences, Pharmaceutical Technology Section, University of Catania, and his team of researchers from Italy, conducted a study in which they assessed the effects of rosemary oil on the skin.[8] The study concluded that rosemary essential oil, when regularly applied or added as the main component to your moisturizer and other creams showed a significant improvement in skin hydration and elasticity.

Rosemary essential oil is not used in skin care as extensively as it is used in hair care, but it does have antimicrobial and antiseptic qualities that make it beneficial in efforts to eliminate eczema, dermatitis, oily skin, and acne. The topical application of the essential oil or a regular massage with the oil helps in toning the skin and removing dryness.


Improves Cognitive Function

Rosemary essential oil is an excellent brain and nerve tonic. It is often used by students during exams because it increases concentration and helps in studying efficiently. It stimulates mental activity and is a good remedy for depression, mental fatigue, and forgetfulness. Whenever your brain is tired, try inhaling a little rosemary oil to remove boredom and renew your mental energy.

In a study conducted by Moss M, et al., head of the Department of Psychology, Northumbria University, found that of 144 test participants who inhaled rosemary oil during an exam displayed significantly higher cognitive function.[9] This is why some researchers are beginning to explore the options for using rosemary essential oil as an alternative therapy for slowing down the onset of Alzheimer’s disease in certain patients because of this apparent connection between boosted neural activity and the essential oil.

Relieves Stress

Rosemary essential oil may help lower the level of cortisol in the saliva.

Cortisol is one of the main stress hormones that are released during the “flight or fight” response of the body to stress.[10] Excess cortisol in the blood that may occur due to chronic stress can wreak havoc on the body, including its hormonal balance and the efficiency of the metabolism.

A study published by Dr. Toshiko Atsuri and Dr.Keiichi Tonosaki, Department of Oral Physiology, Meikai University, School of Dentistry, 1-1, Keyaki-dai, Sakado-shi, Japan, in the Psychiatry Research journal said that inhaling rosemary oil and lavender oil for five minutes significantly reduced the levels of cortisol in the test subject’s saliva, which could decrease the inherent dangers of chronic stress.[11][12]

Boosts Immune System

The same study which found that cortisol levels decreased after simultaneous massage and inhalation of rosemary essential oil also found that the scavenging free radical activity in the test subjects’ bodies also increased significantly.[11] This means that a regular use or inhalation of rosemary essential oil in aromatherapy sessions or in other ways may aid in strengthening the immune system.

Relieves Pain

In a study carried out over a period of two weeks, by South Korean researchers, stroke survivors with shoulder pain, who were given acupressure for 20 minutes, twice daily, with rosemary oil blended with lavender and peppermint oils, experienced a 30% reduction in pain.[13] On the other hand, those who received only acupressure (without rosemary oil) had a 15% reduction in pain.

Another study suggests that rosemary essential oil has anti-inflammatory properties and may help relieve pain.[14] The abilityof rosemary essential oil to relieve pain has resulted in its use in providing relief from headaches, muscle pains, rheumatism, and even arthritis.

Removes Bad Odor

Rosemary has a mesmerizing aroma, which makes rosemary essential oil an excellent inhalant. The oil is used in room fresheners, cosmetics, beauty aids, foods, bath oils, candles, and perfumes because of its unique and intoxicating aroma. Many people use a mixture of rosemary essential oil and water as an air freshener to remove bad odor from the house. However, more scientific evidence is required to support this claim.

Prevents Herpes

An animal study suggests that rosemary oil and Spanish lavender oil help lower the damage to the reproductive function and also reduce free radical activity in diabetic rats.[15]

Respiratory Problems

The scent of the oil has been shown to give relief from throat congestion, and it is also used in the treatment of respiratory allergies, colds, sore throats, and flu. Since rosemary oil also has antiseptic qualities, it is also effective for respiratory infections. According to Dr. Györgyi Horváth and Dr. Kamila Acs’ research report published in the Flavour and Fragrance Journal, rosemary essential oil is antispasmodic and is used in treatments for bronchial asthma.[16]

Anticancer Potential

A group of Tunisian researchers led by Dr. Jardak M, Laboratory of Molecular and Cellular screening Processes, Centre of Biotechnology of Sfax, published a research report in the Lipids in Health and Disease Journal that examined the chemical composition of rosemary essential oil.[17] The study also evaluated its anti-biofilm activity on the biofilm-forming bacterium and its anticancer activity on cancer cell lines. After thorough research, it was concluded that rosemary oil could have a potential role in the treatment of diseases related to infection by microorganisms or the proliferation of cancer cells.

Research is currently being performed to study its potential in treating various types of cancers including those of the colon, stomach, breasts, and lungs.

Enhances Blood Circulation

The benefits of rosemary oil include its use in improving blood circulation. It is said that when people feel cold even in a relatively warm climate, they should try massaging themselves with rosemary essential oil. According to a research study by P. Sagorchev, et al.[18] use of rosemary oil may help improve local blood circulation and also give relief from pain.

Another study published by Dr. Von Schoen-Angerer, et al.[19] involved a woman with Raynaud’s disease, thoroughly massaging her hands with a rosemary oil blend, that helped keep her hands and legs warm. This turned out to be more effective than the time she used regular olive oil.

For the uninitiated, Raynaud’s disease, causes the blood vessels in your fingers and toes to contract to cause them to go cold and lose color.[20]

Instant Mood Uplifter

By sniffing rosemary oil, one can immediately feel rejuvenated and energetic. A study published by Dr. Tapanee Hongratanaworakit in the Scientia Pharmaceutica Journal stated that by applying diluted rosemary oil to the skin, 35 healthy people felt drastically more alert, rejuvenated and happy just within 20-25 minutes.[21] On the contrary, when they applied a placebo oil, there was no significant mood upliftment that was witnessed.

Another study by Moss M, et al.[22] suggests that oils like the olfactory impact of rosemary essential oil may help improve cognitive performance and the feeling of being content.

How to use Rosemary Oil for Hair?

Rosemary essential oil blends well with frankincense, lavender, clary sage, cedarwood, basil, thyme, citronella, lemongrasschamomile, and peppermint oil. There are many ways in which rosemary oil can be applied to hair. Let us look at some of them

  • You can mix rosemary oil with other carrier oils like coconut oil and jojoba oil and apply topically.
  • Dilute rosemary essential oil with a carrier oil like jojoba oil and then apply the mixture to your hair.
  • Mix 20-30 drops of rosemary essential oil with a carrier oil and then rub the mixture onto your scalp and on your hair strands. This is believed to be able to slow graying, stop dandruff, increase growth, and keep the scalp free of irritation or infection.
  • Mix this oil with your shampoo and conditioner. Just make sure not to add too much.

Note: Do not apply the pure oil directly on your scalp.

Where to buy Rosemary Oil?

You can buy rosemary oil in nearly every whole food and health store, in addition to large big-box chains like Walmart and Target. However, one should always request a GC-MS report to confirm the oil is high-quality and free of adulterations. Rosemary is one of the most popular herbs, and its oil enjoys similar fame all over the world. There are different types, chemotypes (rosemary oils with different dominant chemical constituents; e.g. 1,8-cineole CT, verbenone CT, and camphor CT), and strengths of rosemary oil, so do your research well before buying.


  • Rosemary essential oil may, at times, cause allergic reactions, so it should only be used if prescribed or after thorough consultation with your medical specialist.
  • Since rosemary oil is volatile in nature, the oil occasionally causes vomiting and spasms. Therefore, it is advisable to exercise caution while ingesting it.
  • It is strongly suggested that rosemary essential oil should not be used by pregnant, breastfeeding or nursing women.
  • Excessive use of the oil may even lead to miscarriage or disability in the fetus.

Rosemary Oil: FAQs

Q. Do you have to dilute rosemary oil?

A. Rosemary oil is a highly concentrated, volatile substance. Rosemary oil is readily absorbed into your bloodstream when you apply it to your skin. To be used safely, it is advised to dilute rosemary oil with a neutral carrier oil, such as coconut oil. This helps prevent potential irritation of your skin and premature evaporation of the oil.

Q. Is rosemary oil good for pimples?

A. Rosemary oil is excellent at managing sebum production, which means your pores will be clearer, and your skin will be a lot less oily. It’s anti-inflammatory as well, so it treats redness from frequent breakouts and reduces puffiness without causing further irritation.

Q. Does rosemary oil grow hair?

A. Rosemary oil improves both hair thickness and hair growth; it is an excellent choice as it can enhance cellular generation. According to one study, rosemary oil performed as well as minoxidil, a common hair growth treatment, but with less scalp itching as a side effect.

14 Benefits and Uses of Rosemary Essential Oil

Rosemary (Rosmarinus officinalis) is an evergreen shrub with needle-like leaves and a woody aroma (1Trusted Source).

Though best known as a food seasoning, it is one of the most popular aromatic and medicinal plants worldwide (2Trusted Source).

Rosemary’s essential oil — which holds the plant’s core components, or essence — is extracted and sold in small bottles. Despite its name, it is not a true oil, as it doesn’t contain fat (1Trusted Source3Trusted Source).

Due to rosemary oil’s use in folk medicine, many scientists are now testing its potential health benefits (4Trusted Source).

Though most of this research is just beginning, it supports some traditional uses of the oil and illustrates possible new uses.

Here are 14 potential benefits and uses of rosemary essential oil.

1. May Improve Brain Function

In ancient Greece and Rome, rosemary was thought to strengthen memory (5).

Research indicates that inhaling rosemary oil helps prevent the breakdown of acetylcholine, a brain chemical important for thinking, concentration and memory (6Trusted Source7Trusted Source).

When 20 young adults were asked math questions in a small room diffused with rosemary oil, their speed and accuracy increased in direct proportion to the duration the oil was diffused.

Additionally, their blood levels of certain rosemary compounds likewise increased — illustrating that rosemary can enter your body through breathing alone (6Trusted Source).

Similarly, nursing students who breathed rosemary oil while taking a test reported increased concentration and information recall compared to breathing lavender oil or no essential oil at all (8Trusted Source).

Other research suggests that breathing rosemary and other essential oils may improve brain function in older adults with dementia, including those with Alzheimer’s disease (9Trusted Source).

Keep in mind that more research is needed.

SUMMARYBreathing rosemary oil may help you focus and remember information. It may also aid your memory as you age, but more research is needed.

2. Stimulates Hair Growth

One of the most common types of hair loss is androgenetic alopecia, better known as male pattern baldness, though it can also affect females (10).

Rosemary oil treats androgenetic alopecia by preventing a byproduct of testosterone from attacking your hair follicles, which is the cause of this condition (11Trusted Source).

When men with androgenetic alopecia massaged diluted rosemary oil into their scalp twice daily for six months, they experienced the same increase in hair thickness as those who used minoxidil (Rogaine), a common hair regrowth remedy.

Additionally, those who used the rosemary oil reported less scalp itching compared to minoxidil, which suggests that rosemary may be more tolerable (12Trusted Source).

Other research indicates that rosemary oil may fight patchy hair loss, or alopecia areata, which affects up to half the population below age 21 and about 20% of people above 40 (13Trusted Source).

When people with alopecia areata rubbed a rosemary essential oil blend into their scalp each day for seven months, 44% showed improvement in their hair loss compared to only 15% in the control group, who used the neutral oils jojoba and grapeseed (14Trusted Source).

SUMMARYRosemary oil may combat certain types of hair loss, including male pattern baldness and patchy hair loss.

In folk medicine, rosemary is utilized as a mild pain reliever (15Trusted Source).

In a two-week study, stroke survivors with shoulder pain who received a rosemary oil blend with acupressure for 20 minutes twice daily experienced a 30% reduction in pain. Those who received only acupressure had a 15% reduction in pain (16Trusted Source).

Additionally, an animal study determined that rosemary oil was slightly more effective for pain than acetaminophen, a common over-the-counter pain medication (15Trusted Source).

SUMMARYRosemary oil is known in folk medicine as a pain reliever. Preliminary studies support its pain relief benefits and suggest that it may be more effective than acetaminophen.

4. Repels Certain Bugs

For deterring harmful insects that may bite you or infest your garden, consider rosemary oil as a natural alternative to chemical products.

When a rosemary-oil-based pesticide, EcoTrol, was sprayed on greenhouse tomato plants, it reduced the population of two-spotted spider mites by 52% without harming the plants (17Trusted Source).

Rosemary also helps repel certain blood-sucking insects that can spread harmful viruses and bacteria.

When rosemary oil was measured against 11 other essential oils, it had the longest repellent effect on Aedes aegypti mosquitoes, which spread the Zika virus. A dilution of 12.5% rosemary oil repelled 100% of the mosquitoes for 90 minutes (18Trusted Source19).

Additionally, a spray containing 10% of rosemary oil was similarly effective as the chemical insecticide bifenthrin for controlling the spread of black-legged ticks — which harbor Lyme disease — in tick-infested areas in the northeastern US (20Trusted Source).

SUMMARYRosemary oil is used in natural pesticides to kill certain insects. Additionally, the oil helps repel some blood-sucking insects, such as particular mosquitoes and ticks.

5. May Eases Stress

Many factors can cause stress — including school tests. Inhaling rosemary oil may help reduce test anxiety.

When nursing students breathed rosemary oil from an inhaler before and during test time, their pulse decreased by about 9% — while no significant change occurred without rosemary oil (8Trusted Source).

Because increased pulse rates reflect short-term stress and anxiety, rosemary oil may naturally reduce stress (21Trusted Source).

Additionally, when 22 young adults sniffed rosemary oil for 5 minutes, their saliva had 23% lower levels of the stress hormone cortisol compared to those who smelled a non-aromatic compound (22Trusted Source).

Increased cortisol levels can suppress your immune system, contribute to insomnia and cause mood swings, among other potential problems (23).

SUMMARYSimply smelling rosemary oil may ease your stress levels in situations like exam taking. Rosemary may reduce levels of cortisol, a hormone that can have harmful effects on your body.

6. May Increase Circulation

Poor circulation is a common complaint. You may notice it most in your hands and feet.

If you experience cold fingers and toes — even in relatively warm temperatures — rosemary oil is worth considering.

In one study, a woman with Raynaud’s disease — which impairs circulation — massaged her hands with a rosemary oil blend, finding that it helped warm her fingers more than a neutral oil. These effects were confirmed by thermal imaging (24Trusted Source).

If you have Raynaud’s disease, blood vessels in your fingers and toes constrict when you’re cold or stressed, causing them to lose their color and turn cold.

Rosemary oil may help by expanding your blood vessels, thereby warming your blood so that it reaches your fingers and toes more easily (25Trusted Source).

More research is needed to confirm these effects — but rosemary may prove a worthwhile, low-cost experiment.

SUMMARYIf you experience cold fingers or toes, massaging with rosemary oil may help warm them. It may aid conditions like Raynaud’s disease, but more research is needed.

7. May Help Perk You Up

Rosemary oil is commonly used for mental strain and fatigue in folk medicine (26).

When 20 healthy young adults inhaled rosemary oil, they reported feeling about 30% more mentally refreshed and about 25% less drowsy compared to smelling a placebo oil (1Trusted Source).

This increase in alertness corresponded to changes in brain waves and increases in heart rate, breathing and blood pressure (1Trusted Source).

Applying diluted rosemary oil to your skin may provide similar benefits, as it can reach your brain via this route (26).

In one study, applying diluted rosemary oil to the skin caused 35 healthy people to feel significantly more attentive, alert, energetic and cheerful after 20 minutes than when using a placebo oil (26).

Still, more research in this area is needed to confirm these results.

SUMMARYA few small studies suggest that rosemary oil may boost attention, alertness, energy and mood. Yet, more research is warranted.

8. May Reduce Joint Inflammation

Preliminary evidence suggests that rosemary oil may help reduce tissue inflammation that can lead to swelling, pain and stiffness (4Trusted Source27Trusted Source).

It may do so by stemming the migration of white blood cells to injured tissues to release inflammatory chemicals (28Trusted Source).

When people with rheumatoid arthritis were given 15-minute knee massages using a rosemary oil blend three times weekly, they had a 50% decrease in inflammatory knee pain in two weeks, compared to a 12% decrease in those not given the oil (29Trusted Source).

Rheumatoid arthritis is an autoimmune condition in which your body’s own immune system attacks tissues, such as knees and other joints, injuring the joint lining and causing inflammation.

More research is needed on rosemary’s impact on inflammation.

SUMMARYApplying diluted rosemary oil topically may help lower inflammation in injuries and rheumatoid arthritis. However, more research is needed to confirm this.

9–13. Other Uses

Scientists are investigating several other uses of rosemary oil, but human studies are lacking.

Test-tube studies aren’t equivalent to human research that tests essential oils via inhalation or topical application, which are accepted uses for people.

Additionally, some animal studies have administered rosemary oil orally, but this is not recommended. Essential oils should not be swallowed.

Still, rosemary oil may prove useful for:

  • Cancer: Rosemary oil has antioxidant and anti-inflammatory effects, which test-tube studies suggest may fight cancer cells (30Trusted Source31Trusted Source32Trusted Source).
  • Liver and digestive health: Animal studies indicate that rosemary oil may stimulate the release of bile, which is important in fat digestion, and activate your own antioxidant defense mechanisms to protect your liver (33Trusted Source34Trusted Source35Trusted Source).
  • Food poisoning: Rosemary oil can help inhibit the growth of certain strains of bacteria that cause food poisoning. This requires using precise, very small amounts of food-grade oil. Don’t experiment with this at home (363738Trusted Source).
  • Antibiotic side effects: Rosemary and other essential oils may increase the effectiveness of certain antibiotics. This may allow for a lower dose of these drugs, which could reduce side effects (3Trusted Source39Trusted Source40Trusted Source).
  • Antibiotic resistance: Rosemary and other essential oils may weaken the cell walls of antibiotic-resistant bacteria — not only damaging them but also enabling antibiotics to enter (3Trusted Source4142Trusted Source).

SUMMARYPotential future uses of rosemary oil include preventing cancer and food poisoning, as well as supporting liver and digestive health. Yet, no human studies on these effects have been conducted.

14. Easy to Use

Rosemary oil can be inhaled or applied topically. It’s very concentrated, so you should only use a few drops at a time. The small bottles in which it’s sold contain plastic droppers that make it easier to dispense single droplets.

Though some manufacturers claim it’s safe to swallow or consume their essential oils, there isn’t scientific evidence supporting this — especially over the long term. Essential oils should never be swallowed.

Here are a few easy guidelines for inhalation or topical use of rosemary oil.


The simplest way to inhale rosemary oil is to open the bottle and breathe in. Alternately, you can place a few drops on a cloth or tissue and hold it near your face.

Many people use aromatherapy diffusers, which distribute the essential oil into the surrounding air.

In general, avoid placing a diffuser close to babies or young children, as it’s hard to know the amount they’re inhaling.

Topical Use

Rosemary and other essential oils are readily absorbed into your bloodstream when you apply them to your skin.

It’s generally advised to dilute essential oils with a neutral carrier oil, such as jojoba oil. This helps prevent potential irritation of your skin and premature evaporation of the oil (43Trusted Source).

Here are some general guidelines for diluting oils for topical use:

Dilution How to prepare it
Babies 0.3% Use 1 drop essential oil per 1 tablespoon carrier oil
Children 1.0% Use 1 drop essential oil per 1 teaspoon carrier oil
Adults 2.0–4.0% Use 3–6 drops essential oil per 1 teaspoon carrier oil

Once diluted, apply the oil to the bottom of your feet or the body part you’re targeting, such as a sore muscle. Next, rub the oil into your skin. This improves blood flood and absorption of the oil (29Trusted Source).

Avoid applying rosemary and other essential oils to damaged skin or near sensitive areas, such as your eyes.

It’s generally advised to avoid rosemary oil if you’re pregnant or have epilepsy or high blood pressure. Rosemary oil may worsen the latter two conditions (44Trusted Source4546).

SUMMARYYou can inhale rosemary oil or apply it to your skin. A diffuser can help distribute the essential oil in a room. If using rosemary oil topically, dilute it with a carrier oil, such as jojoba oil, to avoid skin irritation.

The Bottom Line

Rosemary essential oil, derived from the common cooking herb, has long been popular in folk medicine and is now proving beneficial in scientific studies.

Though most of this research is preliminary, studies note that this essential oil may boost your health by improving mental focus and memory, fighting hair loss, relieving pain and inflammation, repelling certain insects and easing stress.

If you want to try rosemary oil, simply inhale it or apply a diluted version topically. Remember that the oil is very concentrated, so you only need a few drops at a time.
