Essential Oils for Brain Function and Mental Clarity

While some people’s chronic inability to maintain focus on anything may not be as debilitating as certain physical illnesses, it certainly puts a damper on the quality of the lives they lead. After all, each and every person could be more than they realize.

Wouldn’t it be wonderful if we could all tap into the known and unknown abilities within us and let the world know just what it is we can really do?

Allow us to tell you all about the following essential oils, along with their properties that have been known to help improve brain health and brain function.


1. Rosemary Essential Oil

Rosemary essential oil has a wide variety of uses, but it ranks particularly high among essential oils for brain function. It can help take care of your physical health while also ensuring that your mind is sharp and your memory is clear.

Rosemary Oil

There’s a vast body of evidence that suggests rosemary isn’t your typical plant. Several ancient cultures certainly held it in high regard, and modern science has been doing its part in debunking or confirming the long-held beliefs surrounding its uses.

The Science of Rosemary Essential Oil

Some of the things they found out are promising. For instance, the fact that rosemary and its essential oil can be beneficial for improving memory and mental alertness has been passed down in the traditional lores of many cultures, and certain studies conducted to test if there might actually be some truth to this found the answer to be in the affirmative.

See, one of the primary chemical components of rosemary is 1,8-cineole, and this has been shown to have properties that can enhance the brain’s ability to absorb and retain information. It is so good at doing this, in fact, that its effects are held to be comparable to drugs used to treat dementia.

Having this chemical as a whopping 30% of its makeup, rosemary essential oil can and has shown a capacity to improve test subjects’ cognitive performance after being exposed for a period of time to its scent.

We can easily see just how this benefit might be put to good use. Not only is it a promising natural alternative for helping slow down the progress of dementia and general forgetfulness in older people, but it is also a highly viable option for younger adults to try and enhance their memory and therefore improve their overall intelligence. As a bonus, it could also serve as a preventive measure for neurodegeneration.

Using Rosemary Essential Oil

Rosemary oil can be used in aromatherapy in various ways. You can mix it with a carrier oil to make a massage oil blend, and you can also diffuse it to take in its scent as well as its benefits. 

IMPORTANT NOTE: Children, especially babies, should not be exposed to rosemary essential oil as it can slow down their breathing and may even stop it for a spell, making it extremely dangerous. While it might seem tempting for parents to try alternative medicines to improve their children’s performance at school, rosemary oil might not be the best option.

Please see Precautions for more information on the proper use of essential oils.

2. Sage Essential Oil

Sage essential oil is a versatile and highly useful oil that can help improve cognitive function. “Sage” is often used to describe a person or a piece of advice that has proven to be wise or prudent, and it's a very fitting name indeed. Additionally, during the medieval times in Europe, the sage plant was considered to be helpful in improving memory as well as wisdom in those that ingest or use it.

Sage Oil

This herb has definitely proven itself to be quite useful time and time again. It was found to be versatile and advantageous by ancient Egyptians, Romans, and Greeks. Since the ancient times, people have found many ways to take advantage of sage, from culinary purposes to aromatherapy.

The Science of Sage Essential Oil

The ancients had a lot of ideas that have since been debunked, but it seems that their belief that sage can improve memory has some basis in science.

In a 2003 study on the effects of sage, researchers found that healthy young adults between the ages of 18 and 37 displayed improved recall after taking sage oil capsules. Those that ingested the capsules were shown to perform consistently better than those in a control group that did not ingest the sage oil.

Of course, this is a small study on a field that needs to be delved into more deeply. However, it seems that people that observed the memory-sharpening effects of sage centuries ago may be onto something.

Using Sage Essential Oil

Sage essential oil is thus worth including in your aromatherapy sessions when you’re studying for a big test, preparing for an important presentation, or if you simply want to make sure that you’re taking care of your mind and mental health. After all, what’s there to lose in trying essential oils for brain health and improved thinking processes?

These essential oils blend well with sage essential oil:

  • Bergamot
  • Lemon
  • Rosemary
  • Tea tree

3. Lemon Essential Oil

Lemon essential oil is perhaps best-known for its refreshing. invigorating, and cleansing scent. However, it can also help you pay attention to tasks and it can help improve memory.

Lemon Oil

There is a strong and obvious relationship between attention and memory. Being able to maintain sharp focus for long periods of time leads to a greater capacity for retaining information. This is something that lemon oil can help foster.

The Science of Lemon Essential Oil

In one study, rats were divided into two groups—one for experimenting on and one to serve as controls, which is another way of saying the scientists didn’t do anything to them. The experimental group was made to inhale the scent of lemon essential oil each day for five minutes, then both this and the control group were released in completely separate but identical mazes.

This part of the experiment lasted for ten days, and its aim was to measure the amount of time it would take both groups to memorize the way to a predetermined “goal.”

The results were as you’d expect. The rats exposed to the scent of lemon needed shorter and shorter amounts of time each experimental day to reach the goal.

According to the researchers, the success of the experiment can be attributed to the lemon oil aroma’s stimulation of the rats’ central nervous system, which then led to increased levels of attention.

As we mentioned, sustained focus is key to an enhanced memory. It is also key to increasing work accuracy by more than 50 percent, as a famous Japanese study found after releasing the scent of lemon oil in a room full of workers.

Using Lemon Essential Oil

Perhaps the best way to use lemon oil is to diffuse it in an aromatherapy session. You can do this while studying for a test, writing a report or a paper, memorizing lines, and more.

You can also dilute lemon oil in carrier oil and apply it on your skin. However, citrus essential oils like lemon can cause photosensitivity. When applying lemon oil topically, avoid exposing the area of application to sunlight for at least 12 hours after application.

The following essential oil blend well with lemon essential oil:

  • Rosemary
  • Grapefruit
  • Eucalyptus
  • Cedarwood
  • Lime
  • Lemongrass
  • Ylang ylang
  • Bergamot
  • Tea tree

4. Basil Essential Oil

Basil essential oil has been used for centuries to treat a range of illnesses, both of the body and of the mind. It has been described as the “oil that uplifts and renews,” and its regular use is said to be able to impart mental strength and clarity.

Basil Oil

The Science of Basil Essential Oil

Containing properties that are known to reduce anxiety, nervousness, stress, and fatigue, basil essential oil has also traditionally been used to combat inattention, increase energy, and improve recall. It is considered as one of the best essential oils for memory; a quick inhalation of its scent could drive up focus and strengthen your mental muscles.

In fact, basil is so good at “renewing” that it’s been called an “adaptogen,” and that’s a pretty rare property for an essential oil to boast of. In one study, it has been shown that among other things, the use of basil essential oil could help combat chronic stress.

This is especially beneficial in this day and age where everyone is constantly under pressure. Also, one of the known effects of chronic stress on the body is early signs of aging, which isn't something that anybody would like.

Using Basil Essential Oil

With its distinctive and herbaceous scent, basil essential oil is easy enough to recognize. It can be used in aromatherapy, and can also be used as an ingredient in making soaps and candles.

IMPORTANT NOTE: Pregnant or breastfeeding women are discouraged from using basil essential oil. It has known anti-fertility properties, so those trying to conceive must also avoid it.

As with other essential oils, it might also have effects that could run counter to doctor-prescribed medication. Please seek your health provider’s advice prior to use.

The following essential oils blend well with basil essential oil:

  • Patchouli
  • Cedarwood
  • Tea tree
  • Rosemary
  • Ylang ylang

5. Ylang Ylang Essential Oil

Ylang ylang essential oil may be a somewhat controversial inclusion in a list of essential oils for brain function.  After all, improved cognitive function is often tied to alertness and improved memory, but ylang ylang has been proven to have sedative and calming effects. Thus, wouldn’t it be counterintuitive to those who need to be mentally alert and awake?

Ylang Ylang Oil

It would definitely seem so. However, in some cases, calmness can actually contribute to improving cognition.

The Science of Ylang Ylang Essential Oil

A cluttered, racing mind may definitely seem alert, but it would be able to help much if you need to retain, absorb, and digest information. That state of mind might be even less conducive if you actually need to produce something out of the information you just absorbed, like a research paper or a presentation.

Researchers have found that when your mind is calmer and clearer, you're more likely to be able to learn and process information better. You'll also be able to remember more details and recall them when needed.

Using Ylang Ylang Essential Oil

Meditation has been proven to be an effective way to clear your mind and ease worries. Ylang ylang essential oil is a staple in meditative aromatherapy sessions, and for good reasons. It can help ease worries, reduce feelings of anxiety, and promote an overall sense of calm and clarity of mind.

Ylang ylang essential oil is thus more of a “support” oil--capable of helping clear and calm anxious minds, making them more ready to process and retain more information. You can also meditate with ylang ylang essential oil before starting an aromatherapy session with a more stimulating oil.

These essential oils blend well with ylang ylang essential oil:

  • Patchouli
  • Rosemary
  • Lemon
  • Eucalyptus
  • Cedarwood
  • Bergamot
  • Lemongrass

6. Grapefruit Essential Oil

Grapefruit essential oil is known for its ability to help ease tension, bring back balance to a tired and overwhelmed mind, increase levels of energy, and uplift and rejuvenate.


Grapefruit Oil

Additionally, it has a refreshing scent that stands out even among other citruses. Emotionally, this type of fragrance can only tap into positive and hope-filled thoughts.

The Science of Grapefruit Essential Oil

There’s a theory that says introducing pleasant odors during attention-sensitive tasks is enough to have an effect on cognition, simply because the pleasant smell has elevated the person’s mood first. Under this theory, any aroma that an individual deems “pleasing” can give similar results.

Furthermore, the link between scents and memory is well-established. Not only would specific scents help you remember things quicker, but it could also facilitate faster recall if you inhale the same scent you used during the memorization process.

This principle could work the same way for evoking older memories, especially if they’re tied to a particular emotion.

Using Grapefruit Essential Oil

This essential oil and its scent are perfect if you need something from your past to inspire you, or if you just want to bring back some of the youthful vigor and excitement you used to feel when you were younger.

The following essential oils can blend well with grapefruit essential oil:

  • Rosemary
  • Lemon
  • Cedarwood
  • Patchouli
  • Bergamot
  • Ylang ylang
  • Tea tree
  • Lime

  • Pregnant and breastfeeding women should refrain from using essential oils as many have components that might be adverse to babies. Some essential oils are also natural emmenagogues, which promotes menstruation. While this effect is typically not strong enough to induce a miscarriage, complications might still occur which could endanger both the mother’s and the fetus’ lives.
  • If you have serious conditions for which you’re taking medications, please consult with your health provider on the advisability of using alternative treatments like essential oils. Many may have properties that could interfere with the effects of the drugs you’re taking. People with epilepsy are also highly discouraged from using essential oils.
  • Avoid taking essential oils orally.
  • Cold-pressed citrus essential oils, like grapefruit, tend to be a lot more concentrated while also being highly acidic. 
  • When applied topically, dilution must be properly observed. For most essential oils, the ratio of essential oil to carrier agent is usually one drop per one milliliter, or one teaspoon, as is often used as well.
  • Before any large-scale skin application, perform a patch test first in a non-sensitive part of the skin to see if you have any adverse reaction. If irritation or allergy occurs, please refrain from further use.
  • If you’re applying photosensitive oils like those that come from citrus fruits, wait for at least 12 hours before exposing your skin to the sun. The citrus essential oil might react to the strong light and cause burns or skin pigmentation. Wear sun-protective clothing as an added measure.
  • Keep away from children’s and pets’ reach.
  • Avoid getting essential oils in or near areas with mucous membranes, like the eyes.
  • If undiluted essential oil accidentally spills on the skin, please do not use water to wash it away as oils are not water-soluble and doing this would only spread the oil further on the skin. Instead, use carrier oils to simultaneously dilute and remove the spill.


How to Use Essential Oils to Boost Brain Function

Any of the essential oils listed here can be used on its own to great effect. To make the most of their benefits, they can also be blended together in a personal formula specific to your needs at any given situation.

To make it easier for you, Aroma Foundry has packed them all in a convenient bundle. You won’t have to go far and wide, we have them all here: six all-natural and 100% pure essential oils that can help increase your focus, boost your creativity, improve your memory, and so much more.

There’s a variety of ways you can enjoy these benefits. These include those listed below.


1. Diffusion

Pop a few drops in your diffuser, turn it on, and you’re all set. The exact number of drops would depend on the type of oil you’re using and how long you want the session to last.

Three to five drops are usually enough for a 100-ml capacity tank in a modest-sized room, and citrus essential oils like grapefruit that were made using the cold pressing method would need even less because they’re much more concentrated. Make sure your diffuser is designed to handle its high acidity, though.

The advantage of diffusion is that it spreads the beneficial molecules around the space you’re moving in and you can receive them each time you breathe in.

This would also make sure that no drop would go to waste because a good diffuser would convert every last one to something your entire body can use—anything your lungs couldn’t gather would go to your skin, as it’s also a highly effective conductor of essential oils.


2. Topical application

Want the rejuvenating properties of these oils on your body as well? If you can find the time during a hectic day, then massage your aching head or limbs with these oils, or simply apply some on your pulse points.

For the sake of convenience, you can blend your personal mind-boosting formula beforehand and carry it with you wherever you go.

All you’ll need is a compact, glass UV-filtering bottle to mix and store your blend in. You’ll always be able to keep it on your person, to be whipped out whenever you think you need it.

Make sure the oils are properly diluted in a carrier agent like coconut or olive oil. As we’ve discussed in the Precautions section, a 1:1 ratio of essential oil drop to a milliliter or to a teaspoon of carrier oil is usually the standard.


3. Miscellaneous uses

There are plenty of other ways you could reap the brain-boosting and mind-healing benefits of these six essential oils. If you don’t have a diffuser, you can improvise by adding the drops to a bowl of hot water. Wait a bit for it to cool, then cover the bowl and your head with a towel and inhale the steam.

If you want a mixture you can spray on yourself or in your space, mix up to six drops of your essential oils of choice in 100 ml of purified water or alcohol. Shake the spray bottle well before each use.

As a last example, you can pop a few drops into your bath to unwind after a long stressful day, or add some to your liquid soap or shampoo to motivate you at the start of yet another one. You can also do both.



Just like with people, there are right oils for every job.

If a person’s brain is overstimulated, so much so that it couldn’t possibly function optimally anymore, a sedative type like ylang ylang essential oil can be used to give it a break from work while also preparing it to handle more. If fatigue or persistent inattention is the problem, a stimulant type like sage essential oil might be the right answer.

Our Brain Boost Scents 6-Pack offers various mental benefits to keep your memory and concentration sharp. These six essential oils have science-backed properties to help you improve your productivity, energy, and overall cognitive function.
