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.
