Blending Essential Oils: A Beginner's Guide to Creating Your Own Combinations

One of the most rewarding aspects of aromatherapy is creating your own blends — combining oils to achieve exactly the scent and effect you’re looking for. It’s part art, part science, and entirely enjoyable. Here’s how to get started.

Why Blend Essential Oils?

Single oils are wonderful, but blends can achieve things that individual oils cannot. A well-crafted blend creates a fragrance that is more complex and interesting than any single note, while combining the therapeutic properties of multiple oils for a more rounded effect.

Blending also allows you to personalise your aromatherapy practice — adjusting ratios until you find something that feels exactly right for you.

Understanding Fragrance Notes

Top notes — the first impression. Light, fresh, and volatile — they evaporate quickly (within 1–2 hours). Examples: lemon, bergamot, peppermint, eucalyptus, grapefruit.

Middle notes — the heart of the blend. They emerge after the top notes fade and last several hours. Examples: lavender, geranium, rosemary, chamomile, clary sage, ylang ylang.

Base notes — the foundation. Rich, deep, and long-lasting — they anchor the blend and can linger for days. Examples: frankincense, cedarwood, sandalwood, vetiver, myrrh, patchouli.

A Classic Blending Ratio

A well-balanced blend typically follows a rough ratio of:

• 30% top notes
• 50% middle notes
• 20% base notes

This isn’t a rigid rule — it’s a starting point. Some blends work beautifully with more base notes for a deeper, more grounding effect; others are deliberately top-note-heavy for a fresh, bright character.

How to Blend: Step by Step

1. Choose your intention — what do you want the blend to do? Relax, energise, focus, uplift? This guides your oil selection.
2. Select your oils — choose 2–4 oils to start. More isn’t always better; some of the most beautiful blends are just two or three oils.
3. Start with base notes — add these to your bottle first as they set the foundation.
4. Add middle notes — these form the body of the blend.
5. Add top notes last — these are the most volatile and should be added carefully.
6. Smell as you go — use a scent strip or the back of your hand to assess the blend at each stage.
7. Let it rest — seal the bottle and leave for 24–48 hours. Blends often smell quite different after the oils have had time to marry together.
8. Adjust if needed — add more of a particular note if the balance feels off.

Which Oils Work Well Together?

• Citrus oils blend well with almost everything — particularly florals and woods
• Lavender is the great harmoniser — it works with virtually any other oil
• Frankincense pairs beautifully with citrus, floral, and woody oils
• Peppermint works well with eucalyptus, lemon, and rosemary
• Cedarwood and sandalwood anchor almost any blend as base notes
• Ylang ylang is powerful — use sparingly and blend with bergamot or citrus to balance

Tips for Successful Blending

• Keep notes of every blend you make — ratios, oils used, and your impressions. You’ll want to recreate the good ones.
• Start with small amounts (5–10 drops total) until you’re happy with a blend before making a larger batch.
• Trust your nose — if it smells good to you, it probably is good for you.
• Don’t be discouraged if early blends don’t work out. Blending is a skill that develops with practice.
• Smell coffee beans between oils to reset your olfactory palate.
