Discussion
The experimental results obtained are
inconsistent with prior research. Through previous
studies such as Can Baser (2008) and Wong (2008),
oregano oil inhibited the growth of these three
bacteria significantly in Carvacrol concentrations of
0.625 mg/mL. An important factor, in this study, that
may have caused a deviation from the expected
results is the diluted concentration of Carvacrol in the
sample tested. The oregano oil used from The
Vitamin Shoppe was not a pure source of Carvacrol.
A slight inhibition was due to the presence of
Carvacrol, however, this does not stand to say that it
had a significant effect on the growth of the three
bacteria Staphylococcus aureus, Escherichia Coli,
and Salmonella typhimurium.
