The versatility of tea tree oil makes it a great travel companion. It can be used in so many situations and is like an all in one first aid kit.
Tea tree oil is anti bacterial and antiseptic making it a perfect substance to have on hand for cleaning small cuts and wounds. A possible life-saver especially if you are an off-the-beaten path style traveller. Hospitals or even basic medical care or clean water are quite often, out of reach luxuries in many travel locations.
Finding a clean washroom while traveling can also often be a challenge. Tea tree oil can be used to disinfect surfaces or clean your hands in almost any situation.
I always travel with a small bottle of tea tree oil…so many possible uses and so much better than packing a bunch of chemicals.
