In this study the effect of antimicrobial medicinal herbal essential oils and conventional antifunga...

Antimicrobial activity of the essential oils obtained from leaves, root and the seeds of Diplotaenia damavandica Mozaffarian, Hedge & Lamond, an endemic plant to Iran, was determined against 10 microorganisms using the disk susceptibility test as well as measuring minimum inhibitory concentrations. The results showed that all three oils had antibacterial activity against Bacillus subtilis, Stap...

background and objectives: essential oils are volatile compounds that have been used since middle ages as antimicrobial, anti-inflammatory, sedative, local anesthetic and food flavoring agents.in the current study, essential oils of pelargonium graveolens l’her and vitex agnus-castus l . were analyzed for their antibacterial activities. materials and methods: the chemical compositions of essent...

Research on the biological effects of essential oils on human skin cells is scarce. In the current study, we primarily explored the biological activities of 10 essential oils (nine single and one blend) in a pre-inflamed human dermal fibroblast system that simulated chronic inflammation. We measured levels of proteins critical for inflammation, immune responses, and tissue-remodeling processes....

essential oils are volatile mixtures of hydrocarbons with diverse functional groups. in the current study the effect of essential oils from five medicinal plants including zataria multiflora and nepeta cataria (lamiaceae), tagetes minuta and artemisia sieberi (asteraceae), and trachyspermum ammi (apiaceae) were analyzed using gc-mass spectrometry. the toxicity of these plant essential oils agai...

the objective of the present study was to investigate the effect of different doses of some 7 natural semi-arid medicinal plants’ essential oils on in vitro ruminal digestion and fermentation patterns of a mid-forage (alfalfa hay: concentrates, 1:1) diet. treatments consisted of either basal diet alone (control) or added with 35, 70, 140 or 280 µl l-1 of coriander, oregano, caraway, cumin, cinn...
