With so many essential oils to explore, choosing a scent can feel overwhelming—especially when you are unfamiliar with oils such as Vetiver, Helichrysum or Myrrh.
The Plant Therapy Fragrance Wheel makes the process easier by arranging essential oils into scent families. Once you identify a few aromas you enjoy, you can use their fragrance families to discover other oils with similar characteristics.
How to Use the Fragrance Wheel
The wheel groups essential oils into 10 broad fragrance families: Herbal, Medicinal, Floral, Spice, Wood, Fruity, Mint, Foodlike, Earthy and Fresh.
Start with an oil you already enjoy and locate its family on the wheel. Nearby oils often share similar aromatic qualities, making them useful starting points when shopping, blending or exploring unfamiliar scents. The wheel is a guide rather than a strict rule; natural aromas are complex, and some oils may display characteristics from more than one family.
Herbal Family
Herbal aromas bring to mind fresh leaves, garden herbs and a well-stocked spice rack. This broad family includes Basil, Thyme, Oregano, Lemongrass, Chamomile and Juniper Berry.
Basil smells fresh, sweet and distinctly herbaceous. Lemongrass offers a bright lemony scent with a strong green character. Juniper Berry has a clean, woody and slightly fruity aroma reminiscent of the botanicals used in gin.
Medicinal Family
Medicinal aromas are typically sharp, clean and penetrating. Tea Tree, Eucalyptus and Cajeput are familiar examples. These powerful scents are often balanced with softer citrus, herbal or woody notes.
Eucalyptus has a fresh, camphoraceous aroma with cool, airy qualities. Tea Tree smells crisp, earthy and medicinal and is widely used as an aromatic ingredient in shampoos, soaps and household products.
Floral Family
Floral essential oils range from light and fresh to rich and intensely sweet.
Fresh Florals
Lavender combines soft floral notes with gentle herbal undertones. Rose has a rich, elegant and recognisably floral aroma. Jasmine offers an intense, warm fragrance with sweet and exotic characteristics.
Sweet Florals
Ylang Ylang has a powerful, sweet and tropical floral aroma. A small amount can add depth to perfumes, massage blends and diffuser recipes.
Spice Family
Spice oils have warm, bold aromas reminiscent of baking, cooking and festive celebrations. Examples include Black Pepper, Clove Bud, Ginger and Allspice. These oils can easily dominate a blend, so begin with a small amount.
Clove Bud is rich, warm and unmistakably spicy. Ginger Root combines warm spice with fresh, woody and slightly lemony notes.
Spice essential oils can be especially potent on the skin. Always check the product label and follow its maximum dilution rate.
Wood Family
Wood-family oils evoke bark, roots, forests and freshly cut timber. Their warm, dry or smoky aromas often provide depth and stability in a blend.
Vetiver is deep, earthy, smoky and slightly sweet. Helichrysum is warm, herbaceous, honey-like and subtly woody. Cedarwood has a soft, dry wood scent that blends well with floral, citrus and resinous oils.
Fruity Family
Fruity essential oils are usually bright, lively and approachable. Many are expressed from citrus peels.
Fresh Fruity Oils
Grapefruit has a sparkling, sweet and tangy aroma. Lemon is crisp, zesty and instantly recognisable. Lime often smells sharper and greener than Lemon.
Sweet Fruity Oils
Bergamot combines fresh citrus with delicate floral notes. Sweet Orange has a warm, juicy aroma that pairs easily with spice, floral, wood and other citrus scents.
Some cold-pressed citrus essential oils may be phototoxic. Check the product label before applying them to skin that may be exposed to sunlight or ultraviolet light.
Mint Family
Mint oils are among the strongest and most recognisable aromas. Peppermint has an intense, cool scent, while Spearmint is sweeter, softer and less intensely cooling.
Always check age guidance before using mint oils around children. Not every mint essential oil is suitable for every age group.
Foodlike Family
Foodlike aromas resemble familiar ingredients used in drinks, desserts and baking.
Coffee has a rich, roasted and warming fragrance. Vanilla offers a smooth, sweet and comforting aroma that can soften sharp notes and add warmth to a blend.
Some products described as “Vanilla Essential Oil” are extracts, oleoresins or blends rather than true steam-distilled essential oils. Check the product description for the exact format.
Earthy Family
Earthy aromas are deep, resinous and grounding, often evoking forests, soil and incense.
Frankincense has a balsamic aroma with resinous, woody, green and subtly citrus-like notes. Myrrh offers a dry, warm, resinous scent with smoky and amber-like qualities.
Fresh Family
Fresh—or green—aromas evoke pine needles, leaves, cut grass and open forest air.
Balsam Fir has a fresh evergreen aroma that works beautifully in forest-inspired and festive blends. Carrot Seed has an unusual woody, earthy, dry and slightly spicy scent.
Finding Your Fragrance Family
Try smelling one oil from several families and note whether you prefer aromas that are bright or soft, sweet or dry, fresh or earthy, light or intense. Once you recognise the families you enjoy, the fragrance wheel can help you choose new oils and create more balanced blends.
Stay curious—an unfamiliar aroma may become an unexpected favourite.
Safety Note: The fragrance wheel classifies essential oils by aroma only. It does not indicate whether an oil is suitable for topical use, children, pregnancy, pets or a particular health condition. Always review the individual product’s safety information and dilution instructions before use.
