I first wrote on the best antibacterial essential oils in 2014. That was a while ago. There’s been quite a bit of essential oil research since then.
But I looked at still applies. Why? Because it compared the antibacterial activity of 52 oils on ten drug resistant bacteria and fungi. Fifty-two oils! There hasn’t been research comparing so many since then. That’s why the study is still so relevant.

It found three oils stood above the rest:
- lemongrass
- oregano
- bay
- looked at 500 reports from 1987 to 2001. It found thyme, oregano, mint, cinnamon, salvia and clove oils were the strongest.
- tested 21 oils. It proved cinnamon, clove, geranium, lemon, lime, orange and rosemary oils were the best.
- showed black pepper, tea tree, copaiba, cinnamon cassia, and clove were pretty good.
- studied 6 oils and found oregano, thyme, clove and arborvitae had very strong activity.
They weren’t the only strong antibacterial essential oils though. Rosewood, coriander, palmarosa, tea tree, niaouli, peppermint, spearmint, sage, and marjoram also performed well.
Thyme and vetiver essential oil had great results too.
I did this graphic a while ago, in my blogspot days. It explains the study I just talked about.

But… Yes, there’s a but. The study didn’t include some powerful antibacterial essential oils like cinnamon!
Good thing more research has been done on more oils.
