Maybe a friend gave you a bottle of lavender. Maybe you picked up a diffuser on sale and now it’s sitting on your counter. Either way, you’ve got essential oils and one big question: how do you actually use them?
You’re in the right place. This beginner’s guide walks you through everything in plain English: what essential oils are, the four easiest ways to use them, how many drops to use, which oils to buy first, and the safety rules every beginner should know. By the end, you’ll feel confident using essential oils at home.
Quick answer: how to use essential oils The easiest way for beginners to use essential oils is in a diffuser: add 3–5 drops to 100–200 ml of water and run it for 30–60 minutes. You can also inhale one drop from a tissue, add essential oils to a carrier oil for skin (about 12 drops per 1 fl oz for adults), or mix them into a carrier oil before adding to a warm bath. Never apply undiluted oils to skin, and don’t swallow them.
Essential oils are concentrated aromatic extracts from plants. They capture the natural scent of flowers, leaves, bark, roots and fruit peels. Most are made by steam distillation, where steam releases the plant’s aromatic compounds. Citrus oils are usually cold-pressed from the peel.
Because they’re so concentrated, it takes a lot of plant material to fill one small bottle. That’s why a few drops go a long way, and why you should always respect their strength.
When you breathe in an essential oil, scent molecules travel from the nose to the brain, including the amygdala, the area linked to emotion, according to Johns Hopkins Medicine. That’s why a familiar scent can change how you feel within moments. When essential oils are diluted and applied to skin, small amounts can also be absorbed.
Research on essential oils is still growing, and results in human studies are mixed. Think of essential oils as a way to support a calmer, fresher, more enjoyable daily routine, not as a replacement for medical care.
You’ll see labels like “therapeutic grade” or “clinical grade” on many bottles. In the United States, no government agency grades or certifies essential oils, so these are marketing terms. Instead, look for the plant’s name on the label, a dark glass bottle, and a clear statement that the oil is 100% pure with no added fillers or fragrance.
A diffuser spreads a light mist of essential oil into the air. It’s the easiest, gentlest way to start.
How to use essential oils in a diffuser:
Try it: 4 drops of Lavender in the evening, or 2 drops of Peppermint and 2 drops of Lemongrass for a bright morning.
No diffuser? No problem. Put 1–2 drops on a tissue or cotton ball, hold it a few inches from your nose, and take slow breaths. A personal aromatherapy inhaler (a small tube with a cotton wick) works great on the go, at your desk or in the car.
Don’t sniff straight from the bottle for long periods, and keep oils away from the inside of your nose.
Topical use is popular for massage, roller blends and DIY skin and hair care. The golden rule: always dilute essential oils in a carrier oil first. Carrier oils are plant oils like jojoba, fractionated coconut or sweet almond oil. They spread the essential oil and help lower the risk of irritation.
How to use essential oils on skin:
Want step-by-step help? Read our guide on how to mix essential oils with carrier oils.
A warm bath with essential oils combines inhaling and skin contact. But oil and water don’t mix, so undiluted drops float on top and can irritate skin.
Instead, mix 5–6 drops of essential oil into 1 tablespoon of carrier oil, unscented bath gel or whole milk, then add it to the running water. Lavender is a classic choice for an evening soak.
| Method | Best for | How much |
|---|---|---|
| Diffuser | Whole room, beginners | 3–5 drops in 100–200 ml water |
| Direct inhalation | Quick reset on the go | 1–2 drops on a tissue or inhaler |
| Topical | Massage, roller blends, skin and hair | 2% for adults: 12 drops per 1 fl oz carrier |
| Bath | Evening relaxation | 5–6 drops in 1 tbsp carrier oil |
Dilution sounds technical, but it’s just a ratio of essential oil to carrier oil. For most healthy adults, 2% is the everyday sweet spot.
| Dilution | Use it for | Per 10 ml roller | Per 1 fl oz (30 ml) |
|---|---|---|---|
| 1% | Face, sensitive skin, older adults, daily use | 2 drops | 6 drops |
| 2% | Body oil, roller blends, scalp and hair | 4 drops | 12 drops |
| 3% | Massage on a small area, short-term | 6 drops | 18 drops |
For children, use much lower dilutions and talk to your pediatrician first. Johns Hopkins Medicine suggests 0.25–0.5% for babies 3–24 months and 1–2% for children ages 2–6, and some oils, such as peppermint, should not be used on young children at all.
You don’t need a carrier oil in a water-based diffuser. Add pure essential oil straight to the water.
You don’t need 30 bottles. Start with three versatile oils, learn how you like to use them, then grow your collection.
1. Lavender Essential Oil Soft, floral and calming. Lavender is the most popular essential oil for beginners because it’s gentle and blends with almost everything. Use it in your bedroom diffuser, a bath or a roller blend. Explore more ideas in our guide to essential oils for sleep.
2. Peppermint Essential Oil Cool, crisp and energizing. Diffuse it while you work or study, or add it to a diluted massage oil for a cooling feel. Use it sparingly, as it’s strong, and keep it away from young children.
3. Tea Tree Essential Oil Clean and herbal. A favorite for DIY cleaning sprays and diluted skin and scalp care routines.
| Essential oil | Scent | Popular uses |
|---|---|---|
| Eucalyptus | Fresh, airy | Shower steam, spa-style diffuser blends |
| Lemongrass | Bright, citrusy | Uplifting diffuser blends, fresh home scent |
| Rosemary | Herbal | Focus blends, scalp and hair oils |
| Citronella | Grassy, fresh | Patios and outdoor evenings |
| Wintergreen | Sweet-minty | Massage blends, used sparingly (advanced users) |

Essential oils are natural, but natural doesn’t always mean gentle. Follow these rules and you’ll enjoy them safely.
If you notice a rash, headache, coughing or trouble breathing, stop using the oil and get fresh air. Seek medical help if symptoms don’t go away.

How do you use essential oils for the first time?
Start with a diffuser. Add 3–5 drops of a gentle oil like lavender to the water and run it for 30–60 minutes. It’s the easiest and gentlest way to see how you like a scent.
Can I put essential oils directly on my skin?
No. Always dilute essential oils in a carrier oil first. For most adults, use 12 drops per 1 fl oz (30 ml) of carrier oil, and patch test before wider use.
How many drops of essential oil should I put in a diffuser?
Use 3–5 drops for 100–200 ml of water. In a large room, you can use 5–6 drops.
Can you drink essential oils or add them to water?
We don’t recommend it. Essential oils are highly concentrated, and swallowing them can be harmful. HerboEarth oils are for aromatic and external use only.
What is the best essential oil for beginners?
Lavender. It’s gentle, versatile and blends well with almost every other oil.
Do essential oils expire?
They don’t spoil like food, but they slowly oxidize. Most stay fresh for 1–3 years after opening when stored tightly capped in a cool, dark place.
Are essential oils safe for pets?
Some oils can be harmful to pets, especially cats. Talk to your vet before diffusing around animals, keep sessions short, and always give pets a way to leave the room.
Now you know how to use essential oils with confidence: diffuse them, inhale them, dilute them for skin, and enjoy them in the bath. Start with a few gentle oils, use fewer drops than you think, and build simple rituals you look forward to every day.
Every HerboEarth essential oil is 100% pure, with no fillers or synthetic fragrance, and comes in a 15 ml amber glass bottle. Inspired by the Himalayas of Nepal, our oils ship from Wyoming to all 50 states.
