effects of aqueous extract of cinnamomum zeylanicum on pathogenic gastrointestinal bacteria and probiotic bacteria

Background: bacterial resistance to antibiotics and the progress made in medicinal plants have caused researchers to pay attention to antibacterial compounds in plants. objectives: in this study, we assessed the prebiotic and antipathogenic effects of the aqueous extract of cinnamomum zeylanicum. materials and methods: antibacterial activity of the aqueous extract was performed on various target cultures. determining the activity of the extract n inhibiting the growth of bacteria was done using broth dilution technique. we evaluated the prebiotic activity of extract on lactobacillus reuteri and lactobacillus acidophilus probiotic bacteria. results: c. zeylanicum extract was able to inhibit the growth of all six pathogens. furthermore, c. zeylanicum extract had prebiotic properties for l. reuteri and l. acidophilus bacteria. conclusion: there are antibacterial substances in the aqueous extract of c. zeylanicum, and it has prebiotic activity. therefore, this makes c. zeylanicum considered a good candidate for food supplementation to prevent gastroenteritis.
