There is no scientific evidence that demonstrates the use of essential oils as an effective preventative measure against the COVID-19 virus. Although certain essential oil blends have shown some degree of antiviral properties, these blends will not prevent the spread of the coronavirus.
The Food and Drug Administration and the Federal Trade Commission say that any claims that essential oil products can effectively ward off the coronavirus are fraudulent, putting public health at risk. An FDA task force is working to remove all fraudulent claims from the internet.
The FDA notes that fraudulent COVID-19 products may come in many varieties, including dietary supplements and other foods, as well as products purporting to be drugs, medical devices or vaccines.
