Some fruit juices can help the body fight Covid-19 effectively, says a new study by a group of German scientists.
The publication discusses the potential of plant-derived foods to inactivate SARS-CoV-2 and the influenza virus.
The researchers, led by scientists from the Institute of Molecular Virology at the University of Ulm Medical Center, revealed that aronia melanocarpa juice, as well as pomegranate (punica granatum) and green tea (camellia sinensis) act against both viruses. , which suggests that mouthwash with these fluids can reduce the viral load in the oral cavity and thus decrease the transmission of the virus.
The aronia melanocarpa, known in the United States as “black chokeberry”, is a species of shrub native to eastern North America. This plant has been introduced and is cultivated in Europe.
It is a branching shrub, with glossy dark green leaves that turn red in the fall; grows well in the sun and in semi-shade, forming clumps by means of stems that sprout from the roots.
Its flowers are white or pink, appear in late spring and produce black fruit in September. Many people consider fruits to taste bad.
A five-minute incubation with aronia melanocarpa, pomegranate or green tea juice decreased the infection in the research carried out by German scientists, which indicates that the products tested are generally active against the viruses of the experiment, indicated in the conclusion of the study published in bioRxiv.
Meanwhile, an incubation time of 20 minutes was “only marginally more potent”, suggesting that the antiviral effect is fast-acting.
The scientists observed that aronia melanocarpa juice was several times more efficient at inactivating viruses than other of the fruits or foods tested.
“A five-minute incubation with aronia melanocarpa juice produced more powerful antiviral activities and inactivated influenza A virus (IAV), SARS-CoV-2 and also AdV5 at 99.99%, 96.98% and 93 23%, respectively ”, the researchers confirm.
SARS-CoV-2 was also reduced by approximately 80% from pomegranate juice and green tea after just one minute of incubation.
Scientists recall that SARS-CoV-2 can be transmitted before symptoms appear, which is particularly treacherous. Therefore, the study authors recommend mouthwash and gargles with proven juices and tea to prevent the spread of the virus during the current Covid-19 pandemic.
The use of aronia melanocarpa juice, pomegranate juice, or green tea may offer a chance to minimize the spread of respiratory viruses, alleviate symptoms, and potentially contribute to disease prevention, the authors conclude, adding that research is warranted. clinic of the benefits of these foods.
