The antiviral activity of essential oils

BY Arianna Staruch, ND, ACHS Academic Dean

A recent study looked at preparing a nasal spray from the essential oil of bupleurum root (Radix bupleuri) and tested it in animals for effectiveness. It did show promise as a fever reducer. However, many essential oils can be irritating to mucus membranes and should not be used undiluted or without first doing a skin patch test.

So how can you use essential oil in your everyday life to help reduce to risk of viral infection? Essential oils can be used in the home as antiviral cleaning products. A diffuser with any of the oils listed above, such as eucalyptus, lemon balm, or peppermint, may reduce the airborne viruses in a room. In addition, essential oils may be added to hand creams to help reduce the spread of viruses by contact. Of course, these should be used in addition to the common sense CDC recommendations to wash your hands frequently, cover your mouth and nose with your arm when you sneeze, and to stay home if you are sick. (You should see your primary care provider for a proper diagnosis if you think you may have the seasonal flu or the H1N1 flu, and follow their recommendations.) This fall may be a challenging time because there is the potential for many people to be sick with the flu at the same time, but we can use natural support options, such as essential oils, to keep us healthy.
