Which essential oils are best for energy? Rosemary, Peppermint and citrus oils such as Lemon are the names that appear most often in “uplifting” or daytime aromatherapy. There are also human studies looking at alertness, attention, mood and cognition. But “energising essential oil” is still a much looser idea than caffeine, sleep or a medical treatment for fatigue.
The useful way to approach this topic is to separate three things: how a fragrance smells, what small human studies have found, and what a finished retail product can responsibly claim.
This guide looks at Rosemary, Peppermint, Lemon and brighter citrus-spice profiles, then shows how our Boost roll-on and Grounding candle/wax melts can fit into a daytime routine. If your main question is concentration rather than energy, our existing Aromatherapy for Focus guide explores the research and practical workspace routines in more detail.
Can a Smell Actually Make You Feel More Alert?
There is some experimental evidence that scent can influence subjective state and task performance, but the results are not uniform.
A 2003 study of 144 healthy adults compared Rosemary, Lavender and a no-odour control while participants completed cognitive tasks. The Rosemary group showed differences in several memory measures and remained more alert than the Lavender group after testing.1
A 2021 randomised field trial in 80 shift-working nurses also reported reduced sleepiness and increased alertness following Rosemary aroma exposure compared with a control condition.2
Those findings are interesting, but they do not mean a Rosemary rollerball guarantees more energy, or that scent should be used to push through serious sleep deprivation.
MYTH BUSTER
Rosemary — The Most Obvious Daytime Aromatherapy Oil
Rosemary has a sharp, green, herbal scent and probably has the clearest link to the “focus and alertness” side of aromatherapy. That is partly historical marketing and partly because several small human studies have actually tested Rosemary aroma.
The evidence is still too limited to justify a guaranteed cognitive claim. Different studies use different exposure methods, populations and tasks. But if somebody asks which fragrance profile naturally fits a workday or morning routine, Rosemary is an obvious candidate.
Our Boost Rosemary, Thyme & Lemon CBD Roll-On uses Rosemary as the main herbal direction, with Thyme and Lemon adding sharper herbal and citrus notes. It is a 10ml external-use rollerball with 500mg CBD isolate.
Peppermint — Fresh, Cooling and Widely Studied
Peppermint smells immediately fresh and cool, which is why it often appears in products described as invigorating. The research is more complicated than the marketing.
A 2025 critical scoping review looked specifically at inhaled Peppermint scent and cognition/attention. Only eight human studies met its final criteria, and the authors highlighted substantial heterogeneity in methods and outcomes. Their conclusion was essentially that the topic is interesting but not settled.3
That is exactly the sort of result we want to preserve rather than flatten into “Peppermint boosts focus”. It has research behind it, but the evidence base is too variable for a universal performance promise.
Lemon and Citrus Oils — Brightness and Positive Mood
Citrus scents are often described as uplifting because they smell bright, familiar and fresh. Lemon has also been studied experimentally.
In a controlled study involving 56 healthy adults exposed to Lavender, Lemon or a water control around a laboratory stressor, Lemon odour was associated with improved positive mood compared with the other conditions.4
Again, that is a mood finding under specific study conditions, not evidence that every Lemon-scented product increases energy.
Sweet Orange and Bergamot — A Different Kind of Daytime Fragrance
Not every daytime scent needs to be minty or aggressively herbal. Sweet Orange and Bergamot create a brighter citrus opening that can work well in a living room or work-from-home space.
Our Grounding fragrance combines Sweet Orange and Bergamot with Frankincense and Indian Ginger. The citrus makes the opening brighter; the resin and spice stop it feeling like a simple lemon air freshener.
Despite the name “Grounding”, this fragrance sits within our Boost architecture because it is a brighter daytime home-fragrance direction. We describe the scent rather than promising that it will change your nervous system or emotional state.
What About Essential Oils for Motivation?
“Motivation” is a useful search phrase but a difficult scientific claim. A pleasant scent may help mark the beginning of a routine — opening the laptop, starting a planning session, stretching before work or clearing the desk — but motivation also depends on sleep, mood, task design and plenty of other factors.
That means we would rather say “use a fragrance as a start-of-task cue” than “this essential oil makes you motivated”. It is more realistic and it gives the fragrance a practical job.

The Boost Roll-On: Rosemary, Thyme and Lemon
The Boost CBD Roll-On is our most direct daytime aromatherapy product. Rosemary gives it the main herbal profile, Thyme adds another dry herbaceous note and Lemon brightens the blend.
It is designed as a portable external-use format. We do not claim that pulse-point application delivers Rosemary or CBD rapidly into the bloodstream or that the product treats fatigue, ADHD or impaired concentration.
If you want to understand application rather than ingredients, use our pulse-point roll-on guide.
Grounding Candle and Wax Melts: Daytime Home Fragrance
The Grounding Orange & Bergamot CBD Candle combines Sweet Orange, Bergamot, Frankincense and Indian Ginger in a 120ml vegan vegetable-wax candle with 100mg CBD isolate.
The matching Grounding Orange & Bergamot CBD Wax Melts use the same fragrance family in a wax-melt format. Check the current product label for the box size, CBD content and directions.
The candle gives you flame and candlelight; the melts give you an easy way to change fragrance with a compatible burner. Our Wax Melts vs Candles guide covers that choice in more detail.
TOP TIP
A Simple Morning or Workday Aromatherapy Routine
- Pick the job: starting work, reading, planning, admin or a morning reset.
- Choose one format: portable roll-on or room fragrance.
- Choose the scent direction: Rosemary/Lemon for a sharper herbal-citrus profile; Orange/Bergamot for a brighter room fragrance.
- Remove one distraction: silence notifications or clear the immediate workspace.
- Start the task while the scent is present: that gives the fragrance a repeatable context rather than treating it as an instant productivity hack.
Do Not Use Aromatherapy to Mask Serious Fatigue
A “fresh” scent can feel appropriate when you are tired, but persistent fatigue has many possible causes. Essential oils are not a substitute for adequate sleep, food, hydration, medication review or appropriate healthcare assessment.
This also matters for safety-critical tasks. A study of Rosemary aroma in shift-working nurses is interesting research, but it should not be interpreted as permission to drive, operate machinery or continue working when you are dangerously sleepy.
Essential-Oil Safety for Daytime Use
For topical products, use a finished formulation intended for skin and follow its directions. Do not assume neat Rosemary, Peppermint or Lemon essential oil is suitable for direct application.
For candles and wax melts, do not add extra oil to finished wax. Use heat-resistant equipment, keep flames away from flammable materials and never leave candles or tea-light burners unattended. London Fire Brigade recommends extinguishing candles whenever you leave the room.5

The Bottom Line on Essential Oils for Energy
Rosemary, Peppermint and citrus scents all have enough research or sensory logic to explain why they are common in daytime aromatherapy. The science is interesting but mixed: some studies report alertness, cognition or positive-mood signals, while reviews still highlight heterogeneity and limited evidence.
So we would not sell an essential-oil product as a substitute for energy, sleep or medical care. We would use fragrance for what it does well: creating a recognisable sensory setting for the part of the day you want to begin.
This article provides general information about aromatherapy and fragrance. It is not medical advice or a treatment for fatigue.
Frequently Asked Questions
Frequently Asked Questions
Which essential oils are commonly used for energy and alertness?
Rosemary, Peppermint and citrus oils such as Lemon are commonly associated with daytime or uplifting aromatherapy. Human studies have reported some alertness, cognition or mood signals, but the evidence is not strong enough to promise that a retail aromatherapy product will increase energy or performance.
Does Rosemary essential oil improve focus?
Small human studies have reported differences in cognitive performance and alertness during Rosemary aroma exposure, but these findings do not establish a guaranteed effect from every Rosemary product. For a closer look at the research on concentration, read our Aromatherapy for Focus guide.
Does Peppermint essential oil give you energy?
Peppermint aroma has been studied for attention and cognition, but a 2025 scoping review found the evidence too heterogeneous for firm conclusions. Its fresh scent can suit a daytime routine without being presented as a treatment for fatigue.
What TLD aromatherapy products fit a daytime or Boost routine?
The Boost roll-on uses Rosemary, Thyme and Lemon in a 10ml external-use rollerball. Grounding candle and wax melts use Sweet Orange, Bergamot, Frankincense and Indian Ginger for a brighter citrus-and-spice room fragrance.
Are essential oils a substitute for sleep, caffeine or medical treatment for fatigue?
No. Aromatherapy can be used as a scent-led routine, but it does not replace adequate sleep or assessment of persistent fatigue. If tiredness is persistent or unexplained, seek appropriate medical advice.
