Aside from being used for perfume, aromatherapy and relaxation, essential oils have health benefits as well: relief from nausea, heartburn, headaches and sleep disturbances, to name a few. They act potently against bacteria, microbes and fungi. So potent are they that you must take steps to dilute essential oils, by using carrier oils like coconut or almond oil; otherwise, you might get a severe reaction or even be poisoned by them.

10 Antibacterial essential oils you need in your bug-out bag

Tea tree oil — Tea tree oil has been known for centuries for its healing properties. It has been used to treat fungal, viral and bacterial infections. It is used to treat ringworm, acne, minor burns and athlete's foot. Though it doesn't act as fast as over-the-counter or prescription medicines, it is less irritating than some of them.

Cinnamon oil — Studies show that cinnamon oil is useful in preventing the growth of bacteria between seven and 14 days after a surgical procedure. Some consider this oil as being the strongest among the antibacterial essential oils thanks to its ability to do better with the likes of E. coli, Staphylococcus (staph), Klebsiella pneumoniae, and Pseudomonas aeruginosa.

Chamomile oil — Roman chamomile oil can be useful in managing eczema, diaper rashes, and ear infections. German chamomile is a fantastic antiseptic and works wonders in cleaning wounds.
