  1. Concerns over recommendations made about Cinnamon oil

    18 December 2006

    Prabuseenivasan, Jayakumar, and Ignacimuthu reported the results of their study which clearly show that cinnamon oil and other have antibacterial properties demonstrated in-vitro. 1

    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 agent.

    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
