In the present study, essential oil of Origanum compactum was analysed and its chemical composition was identified by gas chromatography coupled to mass spectrometry (GC-MS). Among thirty two assayed constituents, carvacrol (30.53%), thymol (27.50%) and its precursor g-terpinene (18.20%) were found to be the major components. The oil was investigated for its in vitro antibacterial activity against a panel of standard reference strains using well diffusion and broth dilution methods. In solid medium, the oil was found to be remarkably active against all tested strains except Pseudomonas which showed resistance.

Aromatherapy alternatives for gynaecological pathologies : recurrent vaginal candida and infection caused by the human papilloma virus
Scientific aromatherapy and integrated medicine are taking an increasingly greater role in the treatment of a number of infectious diseases for which conventional medicine has few effective solutions. Powerless and faced with treatment failure, some therapists are actively seeking alternative effective active substances to resolve this inadequacy. When prescribed by competent scientists, essential oils that are chemically and chemotypically defined provide real opportunities with encouraging measurable results that can be observed in clinical practice.

Antigenotoxic effects of three essential oils in diploid yeast (saccaromyces cerevisias) after treatments with UVC radiation
Essential oils (EOs) extracted from medicinal plants such as Origanum compactum, Artemisia herba alba and Cinnamomum camphora are known for their beneficial effects in humans. The present study was undertaken to investigate their possible antigenotoxic effects in an eukaryotic cell system, the yeast Saccharomyces cerevisiae. The EOs alone showed some cytotoxicity and cytoplasmic petite mutations, i.e. mitochondrial damage, but they were unable to induce nuclear genetic events. In combination with exposures to nuclear mutagens such as 254-nm UVC radiation, 8-methoxypsoralen (8-MOP) plus UVA radiation and methylmethane sulfonate (MMS), treatments with these EOs produced a striking increase in the amount of cytoplasmic petite mutations but caused a significant reduction in revertants and mitotic gene convertants induced among survivors of the diploid tester strain D7.
