The Vicks Vaporub uses a combination of Camphor, Eucalyptus and menthol as the active ingredients but this is not suitable for children under 2 and not really recommended for children under six years.

The Vicks BabyRub (aka Vicks Baby Balsam) uses a combination of rosemary, eucalytpus and lavender as a fragrance in a petrolatum base. It is a non-medicated formula and doesn’t actually make any claims except for moisturising and soothing. It is essentially a massage aid and not designed to help with nasal congestion.

If you just want to make the non-medicated product then just refer to the IFRA standards for baby creams and lotions each of the essential oils you want to use.
