Over two hundred essential oils, absolutes, resins, CO2s and carrier oils are used in aromatherapy work. There are other essential oils, absolutes, etc. that exist that are not safe for aromatherapy use. With such a large number of readily available oils, it is cost prohibitive for most people to have every available oil.

When finding aromatherapy recipes online or in books, you may not always have all the oils that are called for in the recipe. That doesn’t mean that you can’t try creating the recipe with other oils that you may have. The aroma or therapeutic outcome will not be identical to the original recipe, but you can often get similar results by carefully substituting an oil that you do have on hand.

Aromatic Substitutions

When substituting an oil in an aromatic blend where your goal is strictly for its aroma and not for a therapeutic emotional or physical purpose, select an oil from the same family of oils (i.e. citrus, floral, spicy, earthy, etc.) as the oil you are substituting for. For instance, if you need a substitute for the essential oil of mandarin, the essential oil of sweet orange will provide a similar aroma. If you need to substitute for rose otto (steam distilled rose essential oil), rose geranium is not perfect, but it can give a suitable result.

Below are a few oils that will give you examples for aromatic substitutions. Even for aromatic blending, you still need to be aware and follow all safety precautions for the oils that you choose.

   *

     Lemon / Grapefruit
   *

     Tangerine / Sweet Orange
   *

     Neroli / Jasmine / Ylang Ylang (neroli, jasmine and ylang ylang are aromatically quite different aside from their intense floral aroma, but they can be substituted for one another in a pinch)
   *

     Lavender / Lavendin
   *

     Peppermint / Spearmint
   *

     Benzoin Resin / Vanilla Absolute
   *

     Cinnamon / Clove

Therapeutic Substitutions

For therapeutic substitutions, the rules of thumb differ from those of aromatic substitutions. Of course you want to create a blend that has a pleasing aroma, but the goal here is to substitute one oil with similar therapeutic benefits for the oil that you do not have. The aroma of the substituted oil can be quite different than the original oil as long as the aroma is still pleasing to work with.

Be  sure to pay close attention to the desired therapeutic action of the original oil and substitute it for an oil that has the same action but that does not introduce any new contraindications or safety hazards.
