Antibacterial EOs for Respiratory Tract Pathogens

Antibacterial study for tonsillitis.  As found in the NIH library

This study is listed in the Oxford Journal.  Antibacterial activity of fourteen essential oils (listed under essential oils for antibacterial activity along with other oils - and listed together under disinfectants ) in their gaseous state (not liquid, not ingested) were tested against the following pathogens:


Haemophilus influenzae,

Streptococcus pneumoniae,

Streptococcus pyogenes and

Staphylococcus aureus


E. coli was used as the control as it showed the least susceptible.  A minimal inhibitory dose - MID - was introduced as a measure of vapor activity.


The essential oils containing terpene ketone, ether and hydrocarbons had high MIDs. The vapour concentration and absorption into agar of EOs reached a maximum absorption one to two hours after rapid evaporation.


These results indicate that a high vapour concentration over a short period of time is most effective.


The inhalation of essential oils assists mucolytic activity, maintained ventilation of the sinuses, provided anti-inflammatory effects on the trachea and reduced asthma.


Antibiotics are not volatile at room temperature and the plants essential oils are. We have evolved over eons synergisticly with plants and our bodies know how to digest them as opposed to artificial antibiotics which are man-made in laboratories.
