In consideration of the rampant bacteria and fungi traversing our world, it is paramount that people discover new methods to prevent or combat these unrelenting pathogens. Hence, the researchers explored the potential of the Alugbati, Mayana, and Makahiya, as bio-hand sanitizers since they may help solve such widespread issues. The bio-hand sanitizer was formulated by mixing the ethanolic extracts of Alugbati, Mayana, and Makahiya. The bio-hand sanitizer was assayed against Escherichia coli (E. coli) at 75% and 100% concentrations following the filter paper disc diffusion method with a commercial hand sanitizer and antibiotic, streptomycin, as positive control and water as negative control. The bio-hand sanitizer exhibited some inhibition on bacterial colony growth. In comparison with the commercial hand sanitizer, the bio-hand sanitizer performs significantly better than hygenix. Additionally, the bio-hand sanitizer, even has higher inhibition than streptomycin, although the difference of inhibition is comparable. The results implicated the remarkable antimicrobial activity of the formulated bio-hand sanitizer from the extracts of Alugbati, Mayana, and Makahiya against the common human pathogen, Escherichia coli (E. coli).
