Abstract

MAUDSLEY and KERR, Department of Microbiology, University of Leeds UK investigated the safety of plant essential oils .

Background

Methodology

The authors determined the sterility of eight plant essential oils obtained from retail outlets. They also examined the ability of oils to support the growth of fungal and bacterial pathogens and assessed the antimicrobial activity against 7 bacterial species and Candida albicans.

Results

All the oils and their respective carriers were found to be sterile . Methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa were not able to survive in oils for longer then 6 hours; however C. albicans was able to survive, but not multiply, in ylang ylang oil for at least 48 hours.

Conclusion
