Prabuseenivasan, Jayakumar, and Ignacimuthu reported the results of their study which
clearly show that cinnamon oil and other have antibacterial properties demonstrated
Though they stated that they have no conflict of interest, the tone of their comments
on previous studies about cinnamon oil, is not satisfactory. The impression created
is that cinnamon oil is exempt from any potential toxicity, is actually used in treating
gonorrhea, and is recommended as a topical preparation against Aspergillus niger.
Yet they conclude that it can be used as antibacterial supplement in the developing
countries towards the development of new therapeutic agents and that additional in-vivo
studies and clinical trials are needed to assess the potential of this oil as an antibacterial
Their findings as presented show that the essential oils tested had antibacterial
activities at the level of concentration that may justify, for instance, their use
in food systems to prevent the growth of food-borne bacteria but they cannot extrapolate
further than that. 2-3 Moreover, essential oils, in general, have been reported to
induce acute poisoning, allergic reactions, epileptic seizures. 4-6. Finally, to even
mention that as an “antiseptic”, cinnamon oil is used against gonnorhea
is simply unacceptable, even more so when the reference cited is three decades old.7
