Essential oils are fragrant and oily mixtures, mostly consisting of monoterpenoids or sesquiterpenoids, used in medicine, cosmetics and pharmaceutical industry for bactericidal, virucidal, fungicidal, antiparasitic, insecticidal, medicinal ve cosmetic purposes. In addition, they provide aroma and preservation in the food industry. Essential oil composition in plants varies depending on plant organ, environmental factors such as the harvest time, extraction method, ecotype, climate, edaphic factors, altitude and topography, genetic factor and their interaction. Essential oils obtained from plants have many important activities according to their active ingredients. The phenolic components contained in essential oils take an active role in the realization of various reactions in both the plant development process and human metabolism or it acts as a trigger for these reactions to take place. In peppermint essential oil the main components are menthol, menthon, isomentone, 1,8-sineol, 1-5% limonene, while in thyme essential oil are carvacrol, linalol, p-cymene, thymol and ß-caryophylde. Linalool, linalyl acetate, terpinen-4-ol, borneol are dominant in lavender essential oil. The constituents of laurel essential oil are 1,8-sineol, α-terpinyl acetate sabin, α-pinene, β-pinene, terpinen-4-ol, α-terpineol, and medicinal sage components are α- and β- tuion, camphor, sineol and borneol. Essential oil components have been observed to exhibit antiviral activity in humans against a wide variety of viruses such as Hepatitis-A virus, Herpes Simplex Virus type-1 (HSV-1), Herpes Simplex Virus type-2 (HSV-2), influenza A (H1N1), enveloped mumps viruses (MV), immunodeficiency virüs (HIV), rotavirus (RV), yellow fever virus and avian influenza. It has been revealed that studies have been conducted on the antiviral effects of essential oils on plants, mostly against tobacco mosaic virus, cucumber mosaic virus, and vesicular stomatitis viruses. The studies conducted are on the mechanisms of action of essential oils and the treatment of viral infections, and there is no up-to-date and comprehensive information on the interaction between essential oil components and antiviral effects. Therefore, further studies are required on the antiphytoviral activity of essential oils and their constituents, and the essential oil concentrations that should be used.
