Seaweed’s potential to fight Covid-19 is recognised by WHO

2 September 2020, at 1:00pm

A recent research article highlighting the potential of seaweed as an effective means of protecting people from coronavirus, has been recognised by the World Health Organisation.

The research suggests that carrageenan is active against several viruses, including H1N1 influenza and SARS-CoV-2

Published in Current Science under the title ‘Can sulphated polysaccharides from seaweed provide prophylactic and/or therapeutic solution to Covid-19 pandemic?’ it was written by Jha Asish, Mathew Suseela and CN Ravishankar, from India’s (CIFT).

It has been placed in the 's website, under the section of ‘COVID-19 Global Literature on Coronavirus Disease’. The endorsement by supports the claims of the scientists about the properties of naturally available seaweed compounds.

Derivatives of seaweeds are known to have many nutraceutical properties. Several polysaccharides isolated from red and green seaweeds have been evaluated for their antiviral characteristics and have been found to inhibit the initial attachment of viruses to host cells, which in turn effectively block the viral entry to human body. Carrageenan, a sulphated polysaccharide from red seaweed, has already been tried as a therapeutic agent for respiratory illness like common colds and influenza virus H1N1.

The new, in vitro study described in the article shows that iota-carrageenan is active against H1N1/2009 influenza. The study also shows that use of sulphated polysaccharide increases the secretions of interferon and interleukins, suggesting that it is a strong immune stimulator. Considering the available scientific knowledge, it is proposed that sulphated polysaccharide from seaweed can be a potent molecule to fight against Covid-19 pandemic, hence a candidate molecule to be studied against SARS-CoV-2.

Though much of the work throughout the globe is happening to find the solution against Covid-19; it can be noted that aquatic plants like seaweed posses many of the medicinal components and deep research in such areas is timely.
