Ginger (Zingiber officinale) has been used as a digestive and circulatory medicine. The intent of this research is to further investigate the antimicrobial properties of ginger. Ginger juice was extracted from the root of the plant. The Kirby-Bauer technique using Mueller-Hinton agar was used to test ginger juice (Zingiber officinale) for antimicrobial properties. Zones of inhibition were measured for the tetracycline disk (positive control), blank disk (negative control), and the ginger disk. The ginger extract indicated a significant anti-microbial effect on the gram-negative (E. coli and P. aeruginosa) bacterial strains tested, but no significant antimicrobial effect on the gram-positive (S. aureus) bacterial strain.
