Dec. six, 2021 — A variety of maritime algae known as ulva, or “sea lettuce,” that’s a diet staple in places like Japan, New Zealand, and Hawaii may have an additional profit for people. Lab experiments suggest that ulvan, an extract from this variety of algae, may enable combat COVID-19.
Other kinds of edible seaweed have also revealed assure as antivirals versus COVID — at minimum in pretty early studies carried out in test tubes and animals. But ulvan has been analyzed as an antiviral treatment method versus sure agricultural and human viruses, way too. This triggered scientists to wonder no matter whether ulvan may well enable avert COVID infections.
To come across out, researchers grew ulva algae in a lab, extracted ulvan, and then exposed cells in test tubes to each the coronavirus and to ulvan. When cells ended up exposed to ulvan, they did not get contaminated with the coronavirus, in accordance to experiment success noted inPeerJ.
In Exam Tubes
That stated, it’s attainable that the procedure employed to extract ulvan from seaweed may affect its antiviral homes. Investigators as opposed two extraction solutions and uncovered 1 of them resulted in ulvan with more than 10 instances the virus-preventing electrical power. This suggests that more analysis is needed to refine the most effective strategy to build ulvan with the most effective antiviral homes, the scientists place out.
Just one restrict of the experiment is that variations in the chemical make-up of the two extracts may well have influenced the consequence, generating it challenging to know for positive how substantially of the antiviral action may well arrive immediately from ulvan as opposed to these chemical compounds.
And even if the seaweed extract proves powerful in more lab checks, it would nevertheless need to have to be analyzed in animals and people. But ought to it verify powerful in human trials, seaweed extract has the possible to enable avert COVID an infection in people who can not simply afford to pay for or access vaccines, especially in reduced-profits nations, the study authors conclude.
