What Are Essential Oils and How Are They Used?

From calming lavender before bedtime to fresh citrus in the morning and warm woody notes during quiet moments, essential oils have a way of making everyday surroundings feel a little more inviting.

But choosing an essential oil isn’t always as simple as picking a pretty bottle. With so many fragrances, types, and uses to explore, it’s natural to wonder which oil is right for you, where to use it, and how to get the best experience from it.

Before you add a bottle to your cart, let’s get familiar with what’s inside it, how these oils are made. 

What Are Essential Oils?

Essential oils are concentrated oils taken from aromatic parts of plants. The source can be flowers, leaves, fruit peels, bark, seeds, roots, or wood. The part used is what gives each oil its own unique scent.

Lemon essential oil, for example, comes from the peel of the fruit, while lavender / eucalyptus essential oil  is made from the flowering tops of the lavender plant.

Unlike the everyday oils we use at home, essential oils are highly concentrated and have their own way of being used. Some can be used on the skin after proper dilution, while others are better enjoyed through diffusers or aroma products.

A quick check of the instructions can help you get the most out of each bottle.

How Are Essential Oils Made?

It all depends on the plant and the part used to capture its aroma.

Flowers, leaves, and herbs are often processed by steam distillation, which helps release the plant’s natural oils. Citrus oils like lemon, orange, and bergamot are usually made by cold pressing the fruit's peel.

Since every plant reacts differently, delicate flowers may need other extraction methods to preserve their fragrance as closely as possible.

Common Types of Essential Oils

There are so many beautiful scents, and the easiest way to find your favorite is to start with the fragrance you already love.

These are the main scent families you’ll come across:

  • Floral oils- Lavender, rose, geranium, and jasmine have soft, sweet fragrances that feel gentle and comforting.

  • Citrus oils- Lemon, orange, and bergamot bring fresh, bright notes that feel clean and refreshing.

  • Woody oils- Sandalwood, cedarwood, and patchouli have warm, earthy scents that add a cozy feel to your space.

  • Herbal oils- Peppermint, rosemary, basil, and eucalyptus have crisp aromas that feel fresh and energizing.

  • Spiced oils- Cinnamon, clove, and cardamom offer warm, rich scents with a hint of sweetness.

Kalla's collection of natural essential oils lets you explore different fragrance families through notes like lavender, rose, jasmine, ylang-ylang, and sandalwood. 

Essential Oil, Fragrance Oil, and Carrier Oil: What Is the Difference?

They may look similar sitting on a shelf, but these three oils are made for very different reasons. Here’s a quick look at what makes essential oils, fragrance oils, and carrier oils different:

Type

What It Is

How It Is Commonly Used

Essential oil

A concentrated aromatic oil taken from plant material

Diffusers, aroma devices, or diluted skin use only when the label allows it

Fragrance oil

A scent blend made to create a particular fragrance

Candles, soaps, perfumes, and home-fragrance products

Carrier oil

A mild oil such as coconut, almond, or jojoba oil

Used to dilute suitable essential oils before skin application

Do not assume that these oils can replace one another. Each one has its own role, which is why checking the label matters before using any oil.

How Are Essential Oils Used?

That tiny bottle can do more than just sit pretty on your shelf. Here are a few ways to actually put it to use.

In a Diffuser

A diffuser is one of the most common ways to use essential oils. Just add water as instructed and put in the recommended number of drops for your diffuser. 

Every diffuser is a little different, so there isn’t one perfect drop count for everyone. Start small and add more later if you want a stronger scent.

In an Aroma Burner

An aroma burner can help spread fragrance slowly throughout your space. If your oil is suitable for this method, add it to water according to the burner instructions and keep it away from direct flame. Remember to check the water level while it’s being used, and don’t let it dry completely.

On an Aroma Stone or Tag

For a lighter fragrance, aroma stones, ceramic pieces, and fragrance tags are good options. They release the scent slowly without making the whole room smell strong at once.

Refresh your Kalla Lavender Aroma Tag with a few drops of lavender essential oil whenever the fragrance starts to fade, and keep it close in your wardrobe, car, or workspace.

Just make sure the item is made to hold oils, as essential oils can mark wood, fabric, paint, or other delicate surfaces.

On the Skin

Don’t apply them directly from the bottle. If an oil is meant for topical use, it should be diluted with a suitable carrier oil and used as mentioned on the label.

How to Choose the Right Essential Oil

Love soft, gentle fragrances? Floral oils like lavender or rose might appeal to you. If you prefer something bright and fresh, citrus oils are worth exploring.

For deeper scents, woody and spiced oils bring a warmer feel, while herbal oils have a crisp, refreshing aroma.

Once you have a scent in mind, check the product details before buying.

A good label or product page should clearly mention:

  • The plant or ingredients used

  • How to use the oil

  • Diffuser or dilution instructions, where applicable

  • Safety information

  • Storage instructions

If you're buying your first essential oil, there's no need to start with a large collection. One fragrance is enough to get started.

Also, don’t choose a bottle only because it says “premium” or “therapeutic.” Clear information about the product tells you much more than a big claim.

How to Use Essential Oils Safely

A few simple things to keep in mind:

  • Follow the directions on the bottle.

  • Keep the room ventilated during aromatic use.

  • Do not apply them directly to the skin.

  • Keep bottles away from open flames, children, and pets.

  • Store them upright with the cap closed properly.

  • Protect them from direct sunlight and heat.

  • Stop using the oil if the scent or skin contact causes discomfort.

Ask a qualified professional before considering topical use during pregnancy, for children, or while managing a medical condition.

Frequently Asked Questions

Can essential oils be applied directly to the skin?

It’s best not to. Essential oils are highly concentrated, so they usually need to be diluted with a suitable carrier oil first. Always check the product instructions before using them on your skin.

How many drops should I add to a diffuser?

There isn’t one fixed number that works for every diffuser. Start with a few drops and adjust as needed based on the diffuser size and how strong you want the fragrance to be.

Is fragrance oil the same as essential oil?

No, they’re different. Essential oils come from aromatic plant parts, while fragrance oils are formulated to create specific scents that may contain natural, synthetic, or both ingredients.

How should essential oils be stored?

Keep them away from sunlight and heat, close the cap properly after every use, and store them somewhere children and pets can’t reach.
