Ally adds Lavender essential oil to her blend in class.

Every week on Facebook, Twitter or email, I get questions about blending:

“Liz, how strong a blend should I make for my husband’s sprained ankle?”   “Liz, I want to use essential oils on my children but don’t know how much is safe.”   “Liz, how many drops of essential oils should I add to cream for my face?”

These are all great questions, and I’m so happy when I get asked!   It tells me that people understand the potency of essential oils and that they need to be used with care and respect.  There can be uncomfortable, even dangerous, consequences when used incorrectly.

Below I’ve made a simple chart you can print out and keep at your blending table for easy reference.   These are the dilutions we use in the classroom at the Aromatic Wisdom Institute.  When in doubt, use less.

Weight of Carrier 1% dilution 2% dilution 3% dilution
1 ounce 5-6 drops 10-12 drops 15-18 drops
2 ounce 10-12 drops 20-24 drops 30-36 drops
4 ounce 20-24 drops 30-36 drops 45-54 drops







1% Dilution: — This dilution is used for children under 12, and seniors over 65, pregnant women and people with long-term illnesses or immune systems disorders.  A 1% dilution is also a good place to start with individuals who are generally sensitive to fragrances, chemicals or other environmental pollutants.

2% Dilution — This dilution is used on adults in good health for blends that support skin care, for natural perfumes, bath oils, and blends you use everyday or long-term.

3% Dilution — This dilution is used when creating a blend for an acute injury, pain relief or getting through a cold or flu.  Blends made at this dilution are used only for a week or two.

Neat:  Using essential oils  “neat” (meaning undiluted – essential oil without any carrier) is inadvisable except in very specific situations.  There are two reasons for this:  1) you can develop a sensitivity to the oils; and 2) many essential oils are too irritating to use without dilution.   Oils can be used neat as follows:  Small specific areas, acute situations (cut or wound, bee sting, bug bite and burn) and for short-term use.  These must be highest quality, non-oxidized oils.
