Antibacterial products have been found to have harmful chemicals like Triclosan. There is currently a need for alternative antibacterial agents to replace Triclosan in many antibacterial products like shampoo, toothpaste, and soaps. This experimental study, which utilized post-test only control group design, aimed to determine the effect of Bermuda grass (Cynodon dactylon) oil as an antibacterial agent that inhibits the growth of Staphylococcus aureus. Sensitivity disks testing was done to find out the efficacy of Bermuda grass oil extract against S. aureus. The application of water served as negative control and that of Amoxicillin solution as the positive control. With the use of t-test and mean, it was found that there is a significant difference in the measure of the area of the zone of inhibition between the negative control group (treated with water) and the experimental group. There is a significant difference in the measure of the area of the zone of inhibition between the positive control group (treated with amoxicillin) and the experimental group. Further, Bermuda grass oil has a positive result in inhibiting the growth of Staphylococcus aureus bacteria, though amoxicillin shows a greater positive effect on the said bacteria. This study would be of great benefit to pharmaceuticals, making Bermuda grass as a potential source of organic antibacterial substances.
