Essential Oil against COVID*: The Cutting Edge of Science

The Cutting Edge of Science cumulated with a long well known Medical History: A Winner without Side Effects

What are we waiting for treating patients as soon as the first symptoms are appearing?
What do we have to win by waiting until the ICU is needed, saturated and people are dying?
Do we want or need the economy to be controlled by fear or by a reasonable free of mind medical science?

 A very recent publication highlights the fact that geranium and lemon essential oils are playing a great role in blocking the lungs cell’s inflammation. (find the abstract and link below).

Geranium and lemon essential oils, thanks to their many natural compounds might be a great early stage or preventive solution against COVID 19.

This being underlined, these essential oils have been the topic of many other researches and validated publications, showing that essential oil can powerfully:

-Strength the immune system naturally, regulate the metabolism.

-Lemon essence is a wonder for our digestive system: it regulates and balances our liver activity. It has strong antivomitive benefits (I really prefer using lemon essence instead of peppermint essential oil, which can be acidic and corrosive on our stomach when swallowed to often…)

-As it has a strong antiseptic and bactericide properties ( against streptococcus, it acts wonderfully against stomach ulcers ( here is a scientific publication proving the huge antibacterial benefits of lemon essence:

Geranium and Lemon Essential Oils and Their Active Compounds Downregulate Angiotensin-Converting Enzyme 2 (ACE2), a SARS-CoV-2 Spike Receptor-Binding Domain, in Epithelial Cells

This recent publication (2020) doesn’t present any conflict of interest, no big pharma stock market involved, however thousands and thousands of lives could potentially be saved today. Read me well: not after months and months of researches on vaccines which might, or might not work.

Her is the abstract I walked you through to make it more accessible in the description above.


Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also known as coronavirus disease-2019 (COVID-19), is a pandemic disease that has been declared as modern history’s gravest health emergency worldwide. Until now, no precise treatment modality has been developed. The angiotensin-converting enzyme 2 (ACE2) receptor, a host cell receptor, has been found to play a crucial role in virus cell entry; therefore, ACE2 blockers can be a potential target for anti-viral intervention. In this study, we evaluated the ACE2 inhibitory effects of 10 essential oils. Among them, geranium and lemon oils displayed significant ACE2 inhibitory effects in epithelial cells. In addition, immunoblotting and qPCR analysis also confirmed that geranium and lemon oils possess potent ACE2 inhibitory effects. Furthermore, the gas chromatography-mass spectrometry (GC-MS) analysis displayed 22 compounds in geranium oil and 9 compounds in lemon oil. Citronellol, geraniol, and neryl acetate were the major compounds of geranium oil and limonene that represented major compound of lemon oil. Next, we found that treatment with citronellol and limonene significantly downregulated ACE2 expression in epithelial cells. The results suggest that geranium and lemon that may contribute to the prevention of the invasion of SARS-CoV-2/COVID-19 into the human body.

As we now know, COVID 19 starts with a corona virus. Symptoms might be coughing, fiever. Breathing distress (short of breath) might not be perceived by patients until a later stage. The phenomenon is described as an happy hypoxy (the low oxygen present in the patients’ blood circulation is making the person feeling ok, even with a very low oxygen saturation percentage) Therefore the patient is only conscious of his/her lack of oxygen in a later stage of the disease, when a cytokine storm (lungs inflammation) is at its peak. Imagery has also shown signs of lung’s thrombosis. It is more and more underlined that blood balance also plays a role in this COVID 19 pandemic. 

Scientific publication underlining essential oils preventing covid 19

The effect of lemon, orange and bergamot essential oils and their components on the survival of Campylobacter jejuni, Escherichia coli O157, Listeria monocytogenes, Bacillus cereus and Staphylococcus aureus in vitro and in food systems), this publication shows the benefits of lemon essence (combined with other essential oils) as anti ulcer treatment. 

-Lemon essence has also anti viral properties such as herpes fighting properties.

Lemon essence has anti allergic benefits when used as nasal spray according to this scientific study

-Lemon essence has vitamin P-like properties : acting on blood fluidity, stimulating microcirculation and improving  blood vessels resistance as well as helping cardiovascular issues on hyperlipidic (overweighted) patients.

Some scientific publications are even underlining anti prostate cancer benefits thanks to its flavonoids compounds thanks to its anti-oxidative, anti-inflammatory, anti-cancer properties

To confirm these above publications, According to some scientific researches published and validated by international scientific peers,Citrus fruits contain a number of metabolites. These active secondary metabolites show several bioactivities of vital importance to human health, including anti-oxidative, anti-inflammatory, anti-cancer, as well as cardiovascular protective effects, neuroprotective effects, etc.

In addition, Citrus fruits have been used as traditional medicinal herbs in several Asian countries.These peels or whole fruits (mature or immature) are known

to treat:



-skin inflammation

-muscle pain

-and ringworm infections

-as well as to lower blood pressure.

Can we swallow lemon essence?

Yes, definitely yes….the prove: 90% of essential oils are consumed in the food industry. It is common to use lemon essence in pastries, in lemonades, in sweet and sour dishes.
