“…The bacteria in this study were Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilits, Escherichia coli, Citrobacter freundii, Proteus vulgaris, Serratia marcescen, Salmonella typhimurium, Klebsiella pneumonia, Pseudomonas aeruginosa, and Enterobacter aerogenes. S. aureus, B. subtilis, and E. coli had multiple strains that were tested [5]. This study showed that a zone of inhibition was recognized with both Gram-positive and Gram-negative bacteria.…”

“…A number of studies were performed to examine exactly how effective the plant is against different bacteria. To start looking into the effects, a study evaluated Pelargonium graveolens against a number of different Gram-positive and Gram-negative bacteria [5]. The bacteria in this study were Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilits, Escherichia coli, Citrobacter freundii, Proteus vulgaris, Serratia marcescen, Salmonella typhimurium, Klebsiella pneumonia, Pseudomonas aeruginosa, and Enterobacter aerogenes.…”

“…Specifically, the rose geranium oil was effective against the Gram-negative bacteria E. coli, P. vulgaris and E. aerogenes but had no effect on P. aeruginosa and K. pneumonia. The bias was shown when viewed against S. aureus, E. faecalis, B. subtilis, and S. epiedermis as these Gram-positive bacteria displayed greater inhibition zones than the Gram-negative bacteria [5,6].…”

“…The results were interpreted as of a zone of inhibition (defined as areas of zero microbial growth). The result of the essential oil extract against the microbes showed that the oil was more effective on the yeasts than the bacteria [5]. It was particularly effective against C. tropicalis and C. albicans.…”

Objectives: Draw upon published research articles for evidence and comprise the collected evidence in an evaluation of the preserving and therapeutic abilities of Pelargonium graveolens. Design:The articles used as research for this research review were discovered by searching public databases with keywords such as "Pelargonium graveolens", "P. graveolens", "pelargoniums", "rose-scented geranium", and "geraniums." Then the articles were reviewed, summarized, and organized based on findings.Results: Many articles were reviewed and many different benefits to the Pelargonium genus were discovered. The major focus in the reviewed articles, however, was on the species Pelargonium graveolens (P. graveolens). P. graveolens displayed many positive benefits. The major benefits that were reviewed were the plant's antibacterial, antioxidant and anti-fungal activities. Other noteworthy benefits that were reviewed include hypoglycemic and anti-reprotoxic activities as well as fairly low toxicity levels. Conclusion:Pelargonium graveolens antibacterial activity shows promise and could move to human trials. However, more research needs to be performed on Gram-negative bacteria because the essential from the plant does not have as strong of an effect as it does on Gram-positive bacteria. As an antioxidant, results are very positive and human trials could ensue. Regarding anti-fungal activity, the essential oil outperformed the drugs currently in place to treat fungal activity and in doing so led to the conclusion that P. graveolens could be used as a viable anti-fungal. Pelargonium graveolens's antioxidant ability is linked to its hypoglycemic effects against diabetes as diabetes has been linked to oxidative stress. Human trials in this area could also ensue. Against toxins that affected the male reproductive system, P. graveolens showed to reverse the negative effects and more research should be done to look into the potential for human trials. In most cases thus far observed, P. graveolens's toxicity level was relatively low and within limits to be harmless to humans. However, it was not low enough to be considered without any hesitation and more research should be performed to look for ways to lower this level.

An experiment was conducted to find the antimicrobial activityof the essential oil from leaves and seeds of Parsley. The antimicrobial activity was examined using paper disc diffusion method and bymicro dilution technique against five pathogenic bacteria (Escherichia coli, Salmonella, Staphylococcus aureus, Yersinia and Vibrio cholera).The MICs (minimum inhibitory concentrations) of the PetroselinumCrispumseeds and leaves essential oil were 8, 0.25% against S. aureus, 4, 0.125% against V.cholera, 16, 0.5% against Yersinia enterocolitica and 32, 1% against the Salmonella enterica and E. coli, respectively.The results support the high efficacy of essential oils to control pathogenic bacteria and their use in developing new systems to prevent bacterial growth, extend the shelf life and increase the safety of the processed food.
