The process of wound healing is influenced by various factors, including the wound-pH. The pH of coffee powder is 4.5-5, which is also the optimal pH for wound healing. The following study will compare the wound-pH of coffee powder with Bacitracin-Neomycin powder (BN). Methods: Wistar rats were divided into three groups, namely coffee group (group I), BN group (group II) and control group (group III), in which the pH measurements were taken at the 24th-hour and 7th-day of treatment respectively. Data analysis was done as the Shapiro Wilk test or Kruskal Wallis test depending on parametric or non-parametric data, and the significance was rated using One Way Anova. Results: At the 24th-hour of treatment the wound-pH of group I was significantly lower compared to group II (p=0.010) and group III (p=0.002). At the 7th- day of treatment, group I was unsignificantly lower than group II (p=0.105), but was significantly lower than group III (p = 0.003), where as group II was unsignificantly lower than group III (p=0.323). Conclusion: This study showed that the pH of the wound fluid which used coffee powder is lower than the BN powder. http://pubs.sciepub.com/js/4/1/3/js-4-1-3.pdf pH coffee powder Bacitracin-Neomycin
