The eucalyptus species, radiata, is chosen for its more gentle approach when compared to the more common Eucalyptus globulus; making it a better option for children, the elderly, or anyone in a frail condition. It still packs a powerful punch against many common viruses and bacteria and brings the added benefits of regulating immune functions and fighting inflammation.
Thyme is also a well-researched antimicrobial effective against a broad spectrum bacteria. The specific thyme for this blend is carefully and thoughtfully selected, as the linalol chemotype has a greater therapeutic margin and is less likely to cause any irritation than other, more common, chemotypes within the same genus and species.
The inclusion of Australian tea tree essential oil in this blend is not only for its well-known effectiveness as an antiviral and antimicrobial agent, but also because its effect with influenza has been studied very specifically. It also shares some notoriety with eucalyptus as having an affinity for supporting the respiratory system. Both essential oils have many of the same terpenoid molecules as constituents.
The addition of lavender certainly adds to the antimicrobial action, but also comforts as only lavender can. Furthermore, it lends a synergistic effect as it combines with the thyme to more than double either of their individual antimicrobial impacts. The result is a drop in the MIC (minimum inhibitory concentration) from 1.3 to .4 percent against staph.
