Antiviral Activity of Essential Oils
The body of evidence regarding the effectiveness of natural botanicals against a great variety of viruses is growing. Over twenty years ago, German scientists found extracts of more than 100 species of the Lamiaceae family to have antiviral effects. This discovery lead to and increase in the examination of essential oils in Europe for the treatment of viral infections.
Essential oils from many plant families have now been demonstrated to have antiviral properties. Interestingly, different plant families exhibit varying degrees of effectiveness depending on the virus strain. This is due to the particular molecular structures found in each type of oil, which penetrate physical entities to varying degrees (different tissues, cell walls, mucous membranes, etc). The effect on each virus strain depends also on the virus structure (enveloped, non-enveloped, molecular symmetry, etc.)
Certainly, one of the reasons for oils’ effectiveness en vivo is their lipophillic character – essential oils are easily absorbed into mammalian tissues, where they may produce the greatest results. In fact, when studying the anti-viral...
