The world-first research from Melbourne’s Doherty Institute found unique garlic varieties were able to reduce the infectiousness of the viruses by up to 99 per cent.

ā€œWe could barely detectĀ any remaining virus genome, indicating nearly complete virucidal activity,ā€ the institute’s Julie McAuley said.

The research released on Wednesday involved 18 months of in-vitro testing of garlic ingredients against theĀ SARS-CoV-2 and influenza type A viruses.

The study was commissioned by Australian Garlic Producers, which is commercialising the most effective garlic varieties and their extracted ingredient.

The novel garlic extraction process is subject to a recently lodged international patent.

ā€œOur extensive research over many years … has shown that garlic varieties not only vary in their agronomic and physiological properties, but also in their biochemical properties,ā€ the company’s chief executive Nick Diamantopoulos said.

ā€œThis type of detailed analysis is theĀ key reason that has led to the identification of unique and specific garlic varieties with superior properties.ā€

The Doherty Institute’s business development director Martin Elhay welcomed the latest findings, saying the organisation was committed to the global effort to combat the spread of Covid-19.
