This is a great guideline for diluting essential oils and using them with children. Essential oils can be very therapeutic, but children and the elderly have more sensitive skin, so diluting them can be helpful.
Remember to do a patch test on a small area for sensitivity and you can always stat with the minimum of essential oil and add more if needed.
I regularly put together essential oils in roller balls for my children to support their emotional and physical needs.
I have made great concentration blends for homework that my oldest child will take to school for testing time and for using when he feels he needs extra support.
