Tea Tree Oil as an Antiviral?

Coronavirus has infected far more people than the two most recent coronavirus-type epidemics combined, SARS in 2003 and MERS in 2012. While scientists are working on a vaccination and hopefully a cure, a review of published, peer-reviewed scientific data on the efficacy of Australian Tea Tree Oil as a potential anti-viral and virucidal agent may be helpful.



"Tea Tree Oil had an inhibitory effect on influenza virus."

Tea Tree Oil's synergistic properties
The antiviral function of several essential oils (Tea Tree Oil, Eucalyptus, Thyme) and their major components (various) were assessed by a group from University of Heidelberg, Germany (Astani et al. 2009). Tea Tree Oil demonstrated a higher antiviral effect versus any other essential oil or individual component.

Demonstrated across a range of viruses
Various university research groups have demonstrated pure Australian Tea Tree Oil to be effective against many different virus types.

  • Influenza 
  • H1N1 (A/PR8, sub. H1N1)
  • Herpes Simplex (HSV) Type I and II

Tea Tree Oil's mode of action
Researchers from Australia and China (Li et al., 2009) stated that Tea Tree oil "...could prevent influenza virus from entering the host cells by disturbing the normal viral membrane fusion procedure."  The authors continued to test and demonstrate the means of this inhibition, as summarized below:
