Like us, you are probably asking yourself this question: Do essential oils protect against viruses? We explored the subject with doctor Sandro Provenzano, specializing in aromatherapy.

Aromatherapy, a serious alternative medicine

The effectiveness of essential oils is often questioned. Even today, we hear that aromatherapy is an alternative medicine, just like homeopathy, reiki, herbal medicine, or sophrology. However, aromatherapy is in a special category among alternative and natural medicine.

Aromatherapy refers to the science of healing (“therapy”) with aromatic plants (“aroma”). In France, only health professionals (doctors, pharmacists, dentists, etc.) can be qualified as aromatherapists. In France, by law, it is mandatory to have medical knowledge so essential oils can be prescribed safely. This shows that these natural extracts are not to be taken lightly.

Aromatherapy is the ancestor of allopathy, conventional medicine mostly practiced in the West today. Since ancient times, humans have observed that scented plants can be used to cure many ailments. But it took many centuries before we really understood how it worked.

The principles of essential oils

By distilling an aromatic plant with water vapor, we extract the essential oil naturally present in the plant. The essential oil is then analyzed by chromatography to identify the chemical compounds (or active ingredients) it contains. Each active ingredient has many properties, and each essential oil contains dozens of these ingredients!

Researchers have studied, isolated, and observed the active ingredients on the human body. When possible, scientists have reproduced these active ingredients using synthetic chemistry to make the drugs currently used in allopathy.

An essential oil is therefore a natural blend of a multitude of active ingredients. These ingredients can have many beneficial effects on health, which is why Family Self Care offers you to take care of yourself with these plant extracts. But remember that they must be used with caution: please refer to our app to avoid risk of wrong dosage.

Undeniable scientific results

One of the properties of the active ingredients in essential oils is the antiviral property. Studies on this subject are numerous and their results are undeniable. In particular, it has been proven that essential oils can have positive effects on fighting against the following viruses:

  • First Coronavirus (SARS-CoV)
  • Herpes Simplex
  • H1N1 flu
  • Avian influenza type H5N1 and subtypes H7N3 and H9N2
  • Anti-infectious bronchitis
  • Dengue

You may have been skeptical about the effectiveness of essential oils in fighting certain viruses. This is understandable, since scientific research on this topic is not yet widespread. Often only the experts hear about these positive benefits, which is a shame.

Below are the scientific articles we have used to write this article. If you’d rather save yourself some tedious reading time and have a specific question about an essential oil or virus, please reach out to us. We will forward your question to our doctor, Dr. Provenzano, so he can provide you with the best possible guidance.

Which essential oils fight against viruses?

Some essential oils are more effective than others at fighting viruses. One of the oils known for its antiviral properties is tea tree essential oil.

It’s known to slow down the replication of herpes (herpes simplex) and the H1N1 flu. In the case of influenza A or the E.coli virus, the disinfectant properties of tea tree oil are remarkable: exposure for 5 to 15 minutes of this oil deactivates the virus by more than 95%! Eucalyptus Radiata essential oil has similar properties against these viruses.

Often, antiviral essential oils also contain active immunostimulating ingredients. They help strengthen our immune system by making it more resistant to an infection (viral or otherwise).

This is the case with the Tea Tree Eucalyptus Radiata and Ravintsara essential oils. Discover the oils best suited to your profile on our SelfCare1® app. Our Natural Defense program will help you boost your immunity in a preventive way.
