Essential oil blending chart and scent-family guide
This essential oil blending chart makes it easier to see which aromas work together. Start with a scent family you enjoy, pair it with a complementary family, then balance quick top notes with slower, deeper notes.



Essential oil blending chart
| Scent family | Example oils | Typical role | Blends well with | Start with |
|---|---|---|---|---|
| Citrus | Lemon, Lime, Grapefruit, Bergamot, Wild Orange | Bright top note | Mint, herbal, floral, wood | 3 drops |
| Floral | Lavender, Ylang Ylang | Soft middle note | Citrus, wood, resinous | 2 drops |
| Mint | Peppermint, Spearmint | Crisp top note | Citrus, herbal, wood | 1 drop |
| Herbal | Rosemary, Tea Tree | Green middle note | Citrus, mint, wood | 2 drops |
| Wood | Cedarwood, Sandalwood | Warm base note | Floral, citrus, herbal | 2 drops |
| Earthy and resinous | Vetiver, Frankincense, Copaiba | Deep base note | Floral, citrus, wood | 1 drop |
The starting amounts are for comparing proportions, not a universal diffuser dose. Always keep the total within your diffuser manufacturer's instructions and use less in a small room.
Six useful essential oil scent families
Citrus
Lemon, Lime, Grapefruit, Bergamot, and Wild Orange. Bright and quick to notice.
Floral
Lavender and Ylang Ylang. Soft, rounded notes that can smooth sharper aromas.
Mint
Peppermint and Spearmint. Crisp notes that often need fewer drops.
Herbal
Rosemary and Tea Tree. Green, direct aromas that pair well with citrus.
Wood
Cedarwood and Sandalwood. Warm, deeper notes that give a blend structure.
Earthy and resinous
Vetiver, Frankincense, and Copaiba. Rich base notes used lightly.
Which essential oils blend well together?
- Citrus + mint: bright and crisp.
- Citrus + herbal: fresh and green.
- Floral + wood: soft and warm.
- Citrus + wood: bright at first, deeper as it settles.
- Floral + resinous: rounded and rich.
- Herbal + wood: outdoorsy and grounded.
A beginner blending formula
For a small diffuser trial, choose one main aroma and one supporting aroma. Begin with three drops of the main oil and two of the supporting oil, then follow your diffuser's capacity and instructions. If you add a third oil, reduce the first two so the total stays within the device guidance.
How top, middle, and base notes work
Top notes such as citrus and mint are usually noticed first and fade sooner. Middle notes such as floral and herbal oils give a blend its central character. Woods and resins tend to sit underneath the blend and linger longer. You do not need all three layers, but a bright oil plus a deeper oil is an easy place to start.
Can two essential oils be mixed together?
Yes, when both oils are suitable for the intended use. Test the aroma on paper first, then follow the product labels and diffuser instructions.
Which essential oils should not be mixed together?
There is no single aroma-only list that applies to every person and use. Check each label for route-specific warnings, start with small amounts, and consider children, pets, pregnancy, health conditions, and medications.
How do I make a blend smell stronger?
First improve balance rather than adding more total oil. Reduce a dominant mint or herbal note, or add one drop of a complementary base note while staying within device guidance.
