I use a blend of essential oils in a roller bottle for topical application. Have not had bronchitis or any colds/flus in the 3 years since I’ve been doing it. I use an allergy blend as well. Haven’t taken any allergy meds for 3 years and I took them daily year-round. EOs work
I take my Thieves oil roller bottle on all outings and travel.
I also make wipes with EO’s to wipe down seats, trays, shopping carts, etc.
