Posted by Firstlight Health on

Australian native botanicals contain powerful essential oils which have demonstrated many amazing properties.

Today we are looking at

  • Lemon myrtle 
  • eucalyptus &
  • Tea Tree oil

Research indicates that these oils exhibit antiviral, antifungal & antimicrobial powers.

Tea Tree Oil

In a study conducted in 2011 researchers tested the effects of Australian Tea Tree Oil on an influenza virus (H1N1) in which "an interesting antiviral activity against Influenza A" was observed.

"These experiments revealed that viral replication was significantly inhibited if TTO was added within 2h of infection, indicating an interference with an early step of the viral replicative cycle of influenza virus."

The main active components. of Tea Tree Oil are terpinen-4-ol, terpinolene, and alfa-terpineol .

Tea Tree & Eucalyptus Oil

Another study conducted in 2001 was titled "Antiviral activity of Australian tea tree oil and eucalyptus oil against herpes simplex virus in cell culture."

This study examined the Antiviral activity of Tea Tree Oil and Eucalyptus Oil against herpes simplex virus type 1 & 2 'in vitro' on cells.

In the experiment "cells were pretreated before viral infection or viruses were incubated with TTO or EUO before infection."

"results indicate that TTO and EUO affect the virus before or during adsorption, but not after penetration into the host cell. "Thus TTO and EUO are capable to exert a direct antiviral effect on HSV."

It is interesting to note that in most of these studies the concentrations used was around 1% or less. 

"Although the active antiherpes components of Australian tea tree and eucalyptus oil are not yet known, their possible application as antiviral agents in recurrent herpes infection is promising."
