Where the Mind Goes, the Chi Follows: How Aromatherapy Works
How aromatherapy works on the mind and body, the idea of chi and energy flow, and how scent affects mood.
In this guide
Aromatherapy works through your sense of smell. When you breathe in an essential oil, its scent reaches the parts of the brain linked to memory and emotion, which is why a smell can change your mood so quickly. Add a calm, focused intention, and you have the heart of the old saying: where the mind goes, the chi follows.
Key takeaways
- Aromatherapy is the use of plant essential oils and their scent to support a wider sense of wellbeing.
- Smell is processed close to the brain's memory and emotion centres, so scent can shift your mood fast.
- The three main ways to use oils are diffusing, inhaling and diluted skin use.
- Intention matters too. Pairing a scent with a calm moment helps anchor your senses.
- Start with a few oils you love, such as lavender, sweet orange and peppermint.
What is aromatherapy?
Aromatherapy is a word most people link with calm, sweet-smelling, relaxing spaces. It is best known for its soothing side, but at heart it is the practice of using scent as part of a wider sense of wellbeing.
It is built around natural essential oils, which are taken from plants and other botanical material. These concentrated oils carry the typical scent of the plant they come from, and that scent sits at the centre of the practice.
How does aromatherapy work?
Much of aromatherapy's power comes from the strong link between smell and mood. Scent is processed in parts of the brain closely tied to memory and emotion. That is why a familiar smell can bring back a feeling or a memory in seconds.
It is also why many people choose certain oils to set the mood of a room or a moment. Something bright and fresh suits the morning, while something soft and grounding suits the evening.
Where the mind goes, the chi follows
Intention plays a part too. As the Chinese saying goes, where the mind goes, the chi (life energy) follows. Pairing a chosen scent with a calm, focused moment is a simple way to mark out time for yourself.
Many people bring aromatherapy into yoga, meditation, breathwork or quiet reflection, using a favourite scent as an anchor for the senses. Trying a few oils before you settle on the one that suits a mood is all part of the fun. Our guide to essential oils for meditation is a good place to start.
How are essential oils used?
Essential oils usually come from flowers, leaves, roots, peel or resin, each chosen for its own scent and character. Flower oils such as rose and neroli are prized for their rich, complex fragrance, while many others are loved for fresher or more grounding notes.
| Method | How it works | Good for |
|---|---|---|
| Diffusing | A diffuser spreads the scent through the room | Scenting and freshening a space |
| Inhaling | Breathe in from the bottle, a tissue or warm water | Enjoying a scent up close |
| Skin use | Well diluted in a carrier oil, bath or balm | Massage and homemade skincare |
A short history of aromatherapy
People have used fragrant plant oils for a very long time. They appear in many ancient cultures, from perfume making and bathing to early natural crafts.
The word "aromatherapy" is much newer. It is often traced to a French chemist in the early twentieth century, who became fascinated by plant oils after working with lavender. From there, aromatherapy grew into the practice we know today, mixing old traditions with a modern, mindful approach to scent. Read more in the ancient power of aromatherapy.
How to start with aromatherapy at home
You do not need a fancy setup. A diffuser in a room you use often, a few drops on a tissue at your desk, or a well-diluted blend in the bath are all easy ways to begin.
Start with one or two oils you really like the smell of, such as lavender or sweet orange. Then build a small collection as you find the scents that suit different parts of your day. Six well-chosen oils are plenty to mix into lots of different blends, and our guide to six organic essential oils can help you choose.
Pro tip
Trust your nose. Bright citrus and herby notes such as lemon and rosemary feel fresh and lively. Soft florals and woods, such as lavender and frankincense, often feel calming.
Is aromatherapy safe?
Safety first
Essential oils are highly concentrated. Never put them neat on your skin. Always dilute them well in a carrier oil and patch test first.
- Keep essential oils out of reach of children and pets.
- If you are pregnant, breastfeeding or have a health condition, get advice before use.
- Never swallow essential oils.
- Diffuse in a well-aired room, and take short breaks between sessions.

FAQs
How does aromatherapy work?
When you breathe in an essential oil, the scent is processed in parts of the brain linked to memory and emotion. That is why scent can change how you feel so quickly. Pairing it with a calm intention makes the effect stronger.
What exactly are essential oils?
Essential oils are concentrated scented extracts from plants, usually made by distilling or pressing. They carry the scent of the flower, leaf, peel or root they come from, which is why each one smells so different.
Do I need a diffuser to enjoy aromatherapy?
No. A diffuser is handy for scenting a room, but you can add a couple of drops to a tissue, a bowl of warm water or a well-diluted carrier oil. Many people start without any special kit and add a diffuser later.
Which oils are good for beginners?
Lavender, sweet orange, lemon, eucalyptus, peppermint and rosemary make a great starter kit. They are widely loved, blend easily with each other and suit lots of everyday moments.
Can I put essential oils directly on my skin?
No. Essential oils are far too strong to use neat. Always dilute them in a carrier oil such as jojoba or sweet almond, keep the dilution low, and patch test on a small area first.
How do I choose an oil for a particular mood?
Trust your nose. Citrus and herby scents feel fresh and lively, while soft florals and woody scents feel calming. Try a few and keep the ones you truly enjoy in that moment.
The bottom line
Aromatherapy works by linking scent to the parts of the brain that shape mood and memory, and your intention helps guide the way you feel. Start small, with a few oils you love, and build from there.
