Antibacterial activity of cymbopogon citratus (Lemon grass) citral essential oil extract against Escherichia coli and enterobacter aerogenes

The study utilized an experimental method of research. Randomized complete block design was employed in assigning variables and gathering data. Cymbopogon citratus was collected from Dasmariñas, Cavite, Philippines. Extracted citral from lemon grass and bacteria were obtained from Department of Science and Technology-Industrial Technology Development Institute (DOST-ITDI), Taguig, Metro Manila, Philippines. Measuring the bacterial growth and zone of inhibitions compared the antibacterial activity of Cymbopogon citratus citral leaf extract against bacterial pathogens. Based on the results, Cymbopogon citratus leaf essential oil extract showed complete inhibition activity against Enterobacter aerogenes and Escherichia coli. The positive controls, Meropenem and Cefuroxime also showed complete inhibition activity against Enterobacter aerogenes and Escherichia coli. The positive controls, Meropenem and Cefuroxime also showed complete inhibition of Enterobacter aerogenes and Escherichia coli respectively. Cefuroxime showed severe reactivity against the organism, with the inhibitory zone extended 10 mm beyond the specimen. The negative controls, sample free discs, yielded no detectable zone of inhibitions against bacteria. Therefore, Cymbopogon citratus leaf essential oil (citral) had complete inhibitory activity against Eschirichia coli and Enterobacter aerogenes. It had slightly wider zone of inhibition in Escherichia coli (12.22mm) compared to the zone of inhibition in Enterobacter aerogenes (11.64mm). Cymbopogon citratus leaf essential oil (citral) had mild reactivity against the two organisms while Cefuroxime and Meropenem showed severe reactivity against E. coli and E. aerogenes, respectively

Relationship between herbal medicine knowledge and self-medication with herbal medicine among 20-45 year old adults in Bagong Bayan District, Dasmarinas, Cavite

A cross sectional-analytic design was utilized in this study. Twenty eight (28) adults aged 20 to 45 years old residing in Bagong Bayan District, Dasmarinas, Cavite in 2016 were chosen as respondents using two-stage cluster sampling. A questionnaire guided interview was the instrument utilized and data was analysed using frequency, proportion, mean, range, and chi-square. Results showed that knowledge on herbal medicine had no significant relationship with self-medication with herbal medicine. It was recommended that further studies should be done to explore the correlation between herbal medicine knowledge and use in Dasmarinas, Cavite. The variables between cultural beliefs and self-medication with herbal medicine could also be explored
