ABSTRACT
This chapter deals with an overview of the research results of antibacterial, antiviral, antinociceptive, anti-inammatory, vasodilatory, and penetration enhancing activity of essential oils (EO) and covers the literature from 2009 to March 2014. It is well known that EOs exert many effects in the human and animal body. Many authors before have described several biological activities. This treatise should afford an overview of the research results concerning the aforementioned topics from 2009 to 2014 following earlier chapters. The treatment of common disease and indispositions, rheumatoid arthritis, pain, high blood pressure, cancer, and many more, with alternative methods such as EOs, is still current. Because of a high rate of resistances against common treatment, science is in the quest of alternative or at least complementary treatment opportunities.
