New research has identified a novel treatment and preventative measure against COVID-19 – the viral disease caused by SARS-CoV-2. According to the research, published in the journal Medical Hypotheses, hesperidin – a compound in orange peels – can block coronavirus from entering host cells through ACE2 receptors which can prevent the infection. “Anti-viral activity of hesperidin might constitute a treatment option for COVID-19 through improving host cellular immunity against infection and its good anti-inflammatory activity may help in controlling cytokine storm,” writes the researchers.

A cytokine storm is an overreaction of the body’s immune system.

“In some people with COVID-19, the immune system releases immune messengers, called cytokines, into the bloodstream out of proportion to the threat or long after the virus is no longer a threat,” explains Harvard Health.

When this happens, the immune system attacks the body’s own tissues, potentially causing significant harm.

“A cytokine storm triggers an exaggerated inflammatory response that may damage the liver, blood vessels, kidneys, and lungs, and increase formation of blood clots throughout the body,” says Harvard Health.

It adds: “Ultimately, the cytokine storm may cause more harm than the coronavirus itself.”

Do these findings suggest a glass of orange juice offers protection against COVID-19?

Speaking to Holly and Phill on ITV’s This Morning earlier, Dr Philippa said the findings are encouraging.

However, as the study relates to the chemical itself and not oranges, it is too soon to know for sure whether the benefits extend to drinking orange juice.

“More research needs to be done but a glass of orange juice may help,” she said.
