Can CBD oil be useful against viruses like Covid19?

Some work suggests that CBD oil may be beneficial for certain viral diseases, but more studies are still needed.

The cannabidiol (CBD) is one of the major cannabinoids present in cannabis or hemp (Cannabis sativa) and no psychotropic effects and addictive potential.

Although some information has been viralized that ensures that this cannabiodie could be useful against the coronavirus, the truth is that there is no solid research in progress on the effect of CBD on the Covid-19 coronavirus. Where does this rumor come from then?


There is currently a CBD-based medication, Epidiolex , to treat seizures associated with two rare types of epilepsy. There are no other officially approved therapeutic indications.

Apart from this pharmacological use, CBD is in Europe in a very confusing legal situation. In many countries of the Union CBD is approved as a food supplement.

A regulation by the EFSA (European Food Safety Authority) is expected to clarify the situation in the coming months.

Meanwhile, CBD products can be purchased on internet sites, to which they attribute a long list of properties, including their efficacy against Covid19. For this reason, researchers from the University of Imbrusia (Italy) and the Imperial College London (United Kingdom) have decided to review the available scientific literature and the claims of specialized websites to assess the current state of knowledge regarding the use of CBD in viral diseases.


Researchers have found scientific studies supporting the use of CBD for the treatment of diseases of viral origin such as hepatitis C and multiple sclerosis (the viral origin of this disease is currently a hypothesis).

However, they add that the results are encouraging but preliminary and that many new studies are needed before CBD hits the market as a treatment for viral diseases.

Other studies suggest that CBD does not have a direct antiviral effect, but that its recognized anti-inflammatory and analgesic properties may be useful in the treatment of viral infections such as oral and genital herpes and herpes zoster and, even, Ebola.

A study on the use of topical CBD oil is currently underway to determine its efficacy in inactivating Zika and West Nile viruses. But, as we have already said, there is no solid research in progress on the effect of CBD on the Covid-19 coronavirus.


CBD acts on the endocannabinoid system, which is involved in the regulation of sleep, appetite, pain, and the immune response.

Studies have shown that CBD can help reduce chronic pain in patients with multiple sclerosis and rheumatoid arthritis. It also mitigates anxiety and depression, reduces blood pressure.

Although CBD is a fairly safe substance, it is advisable that people who receive any medication consult their doctor before taking it. In some cases it can cause side effects like diarrhea, appetite changes, and fatigue.

Consultation with the doctor is also essential to obtain a correct diagnosis. In the event that you suspect that you may be infected with Covid19, you should immediately contact the health services.
