Antiviral properties of Essential Oils: What do we know?

Abstract

This narrative review delves into the antiviral properties of essential oils and aromatherapy, a field gaining prominence recently. Essential oils are noted for their pharmacological effects, particularly their antiviral capabilities. The review pays special attention to essential oils' effectiveness against influenza and coronaviruses. A comprehensive review in this context underscores the diverse chemical compounds in essential oils that offer broad-spectrum antiviral mechanisms. This is crucial given the growing resistance to conventional antiviral drugs, positioning plant-derived essential oils as potential novel antiviral agents. The hypothesis posited in this review is that essential oils could be effective natural antiviral agents, potentially useful as complementary or alternative therapies in viral infections. The review underscores the significance of essential oils' antiviral properties in enhancing human health, advocating for more focused research in this area.
