Can essential oils and antibiotics be used together? by Robert Tisserand Frankincense Oil and Cancer in Perspective by Robert Tisserand Robert Tisserand notes that: "So, if you are looking for a natural substance to help prevent or treat cancer, frankincense oil should not be your first choice. Look instead to turmeric/curcumin, to cannabis/cannabinoids, to garlic/garlic oil, and to frankincense extract, which is sold in capsule form. Following that, I would consider essential oils of cinnamon bark, lemongrass, citronella, turmeric, orange, lemon and bergamot. I have not discussed them all here but these have, in my opinion, a better shot than frankincense oil. Then again, different oils apply to different cancers, and I’m not addressing that here."
Combination of essential oils and antibiotics reduce antibiotic resistance in plasmid-conferred multidrug resistant bacteria. "The finding highlighted the potential of peppermint, cinnamon bark and lavender essential oils being as antibiotic resistance modifying agent. Reduced usage of antibiotics could be employed as a treatment strategy to decrease the adverse effects and possibly to reverse the beta-lactam antibiotic resistance."

Kurt Schnaubelt writes in reference to reading or hearing "dire warnings about the use of Cinnamon and Clove oil, that the 'Never to be used' phrase attached to these two essential oils" is "resoundingly ignored by those who really used essential oils. The antibacterial effects of Cinnamon Bark oil make it one of the best options when a person encounters violent bacterial infections of the intestinal tract, especially while traveling in unfamiliar territory! The choice is between being pointlessly scared by the defensive writing of an author who probably had never been in a comparable situation or effectively ending the debilitating condition with a few drops of Cinnamon oil."
