Why dilute?

Essential oils do not become less effective when a carrier oil (such as coconut oil, grapeseed oil, or whatever cooking oil available) is added, instead it just delays absorption into the skin so there is a longer lasting effect and a larger surface area can be covered than when an oil is used neat (undiluted). Plus, pure EOs evaporate quickly, so a carrier oil will help them stick around longer! With Young Living’s oils being so pure and potent, it is easy to forget that 1 drop will go a long way. 30 drops of oil in a 10mL roller will work, but maybe 5-10 is all that is needed for the same result. Neat oils can always be diluted in a roll on to great effect.

It is best to START SLOW, and dilute more that suggested here, then you can always add more EO or carrier oil to make YOUR perfect blend. The amount listed is the maximum amount recommended and usually will not be needed. If you have sensitive skin or are elderly, definitely use less EO!!!

Use this calculator as an approximate guide, make sure you fill the rest of your roll on with carrier oil if calculating roller bottle drops!

General dilution guidelines for different ages are usually too general, listing a percentage and recommendations such as 1 drop per teaspoon. This is great, but doesn’t distinguish between different recommended dilution ratios from Young Living. Lavender requires no dilution for adults and Thieves specifies 4 drops of carrier oil to 1 drop of EO so 1 drop in a teaspoon of carrier oil is not going to be the right amount for both of these oils! This calculator takes the guesswork out and recommends suggested dilutions based on age and the bottle label. Use anywhere up to that amount, depending on what feels right for you and your family.

Peppermint, eucalyptus, rosemary, and wintergreen should be applied well diluted to bottoms of the feet (not the chest area) of children 5 and younger with a history of respiratory disorders or seizures.
