Basically, the differences in inhibition of yeast strain obtained from essential oil (liquid phase, direct contact with the culture media) and the vapour can be attributed to the differences in diffusion coefficients of the antimicrobial compounds present in the eucalyptus oil when they have to diffuse in the agar compared to the diffusion in vapour phase 35 In our study, the oil dose requirement was significantly reduced with the combination of the two treatments.
Simplified, it's using seven different essential oils in defined patterns on the back to create an emotional release or it can also be done by applying those seven different essential oils to the hands or the feet on certain reflexology points to trigger a gentle emotional release.
This shows that possible synergistic effect of minor and major components determines the final antimicrobial activity of the essential oils 22 Based on the chemical composition, it can be concluded that the antimicrobial activity of the oil is apparently attributed to its high content of oxygenated monoterpenes.
Eucalyptus oil is used in flavouring Cineole-based eucalyptus oil is used as a flavouring at low levels (0.002%) in various products, including baked goods , confectionery , meat products and beverages 8 Eucalyptus oil has antimicrobial activity against a broad range of foodborne human pathogens and food spoilage microorganisms 9 Non-cineole peppermint gum , strawberry gum and lemon ironbark are also used as flavouring.

In fact a 2013 study conducted to investigate the "effects of eucalyptus oil inhalation on pain and inflammatory responses after total knee replacement" suggested that, "inhalation of eucalyptus oil was effective in decreasing patient's pain and blood pressure following TKR."
