Abstract

Infectious diseases due to diseases caused by the entry and proliferation of microorganisms such as bacteria. Balm (Polygala paniculata L.) is useful in healing gonorrhea, rheumatism and wound healing. The purpose of this study was to study the antibacterial activity of ethanol extracts of balm plants and to determine the effective concentration in inhibiting the growth of Staphylococcus aureus and Escherichia coli. The research method was carried out experimentally, and testing for antibacterial activity was carried out using agar diffusion methods. Concentration variations consisted of 50%, 25%, 12.5%, 6.25%, distilled water as negative control and chloramphenicol as positive control. The results showed that all results showed antibacterial activity with a medium category.
