The studies examined herein were done in vitro. However, more
tests need to be conducted to determine the antimicrobial effects of chili
peppers in vivo, especially because such a large number of people eat
peppers. This could be a potential means through which to minimize
the effect of foodborne pathogens when there is an outbreak. Graham
et al. [10] were unable to confirm the hypothesis that capsaicin has an
inhibitory effect on H. pylori in vivo. They believe that natural substances
and folk remedies should undergo testing in vivo before publication of
the in vitro results to reduce the possibility of misinforming the public
regarding the potential usefulness of these agents.
