Background: Wound healing is a multifactorial event with wound bed preparation (WBP) being the most important part of it. Pseudomonas aeruginosa is a significant cause of wound infections delaying the process of WBP. The growth of pseudomonas is suppressed in acidic media. Vinegar (acetic acid) has been in use to provide acidic media to suppress the growth of pseudomonas. Citrus groups of fruits such as lemon, orange, and grapes are rich sources of Vitamin C (ascorbic acid) and citric acid.

Materials and Methods: This is a comparative prospective study done in two groups having 3 patients in each group. Group A patients were investigated for the effect of local application of lemon juice for providing acidic media in wounds to suppress growth of pseudomonas to enhance wound bed preparation (WBP) for reconstruction. Group B included 3 patients treated by povidone iodine.

Results: On an average the number of applications of Lemon juice therapy required was less than povidone-iodine to control pseudomonas infection in wounds.

Conclusion: Lemon Juice can be used as a source of providing acidic media for suppressing the growth of pseudomonas infection in wounds. It is an easily available and natural source of acidic media.
