In a recent compelling article, two US researchers reported that certain natural health products could act as antiviral agents.
They pointed particularly to liquid spirulina to provide relief to people infected with encapsulated RNA viruses. These include influenza and coronavirus. They reported that:
“Both influenza and coronavirus cause an inflammatory storm in the lungs. It is this inflammatory storm that leads to acute respiratory distress, organ failure, and death.
Certain nutraceuticals may help to reduce the inflammation in the lungs from RNA viruses. Others may help boost immunity’s response to these viruses, which is the body’s primary way to help create antiviral antibodies to fight off viral infections.
They found that Phycocyanobilin (PCB) in liquid spirulina inhibits such an “inflammatory storm” caused by the NAPDH oxidase enzyme.
“This phenomenon likely explains many of spirulina’ s profound antioxidant and anti-inflammatory effects. When spirulina, phycocyanin in spitulina, or PCB itself are administered in rodent models of human pathology.”
Hence, ingestion of spirulina or of spirulina extracts enriched in PCB may have potential for boosting immunity’s response in the context of RNA virus infection. Oral administration of a cold-water spirulina extract rich in phycocyanin has been found to decrease mortality in influenza-infected mice.
