Hypothesis
To evaluate the antibacterial activity of 21 plant essential oils against six bacterial species.
Conclusion
Majority of the oils showed antibacterial activity against the tested strains, with cinnamon, clove, and lime oils being particularly effective.
Supporting Evidence
- 19 out of 21 essential oils showed antibacterial activity against one or more strains.
- Cinnamon oil showed significant inhibitory effect against multiple bacterial species.
- Bacillus subtilis was the most susceptible to the tested oils.
Takeaway
This study found that many plant oils can kill bacteria, and cinnamon oil is especially good at it.
Methodology
Essential oils were screened using disc diffusion and minimum inhibitory concentration (MIC) methods against various bacterial strains.
Limitations
Not all essential oils tested showed antibacterial activity, and the study was limited to in vitro conditions.
