I recommend making this up and swiping down the spine or on the bottoms of everyone’s feet at least once per day as a preventative. You can use it more frequently if symptoms of illness creep in.
In a 10 mL roller combine:
10 drops Frankincense
10 drops Lemon
10 drops OnGuard
5 drops Oregano
10 drops Tea Tree
Top with a carrier oil, and apply down the spine morning and night.
*Dilute further for smaller children*
