The use of essential oils and aromatherapy has gained popularity for people looking for natural alternatives to conventional therapies for cold and flu symptoms.

Essential oils have anti-inflammatory, antiviral, antimicrobial, and astringent properties. These oils come in many different formulations including topical and vaporized in a diffuser.

Essential oils may be used topically in conjunction with a carrier oil such as coconut, olive, or grapeseed oil. Sometimes these preparations come combined in a rollerball device to aid topical application.

Another study shows that the essential oils of cinnamon, clove, pimento, thyme, oregano, and rosemary were shown to possess strong antibacterial activity. Clove oil was found to be the most effective among all the tested essential oils.
