Echinacea shows promise against influenzaEthanolic Extract from (L.) Moench Inhibits Influenza A/B and Respiratory Syncytial Virus Infection : Preventive Agent for Viral Respiratory Infections.
Most Relevant Research
We focused on how echinacea, a well-known wildflower, can combat viruses that commonly cause respiratory infections, specifically influenza A and B, as well as respiratory syncytial virus (RSV). Through a methodical approach, we evaluated the effects of a 60% ethanol extract of echinacea and its active compound, chicoric acid (CA), on these viruses.
Our research utilized various tests to measure the antiviral effectiveness of echinacea. We observed that both the extract and chicoric acid significantly reduced the infectivity of H1N1, IVB, and RSV-A in controlled experiments. Notably, our findings indicated a decrease in viral gene expression and confirmed through microscopy that echinacea's components could limit the ability of these viruses to infect host cells.
Additionally, we found that echinacea's extract and chicoric acid effectively hindered the attachment of H1N1 and IVB viruses to cell receptors, showcasing their potential utility in preventing these viral infections. With this strong set of results, we believe that echinacea could serve as a promising natural remedy or ingredient in functional health foods aimed at reducing the impact of viral respiratory infections.

Most Useful Review
Very effective for influenza. I have repurchased this product multiple times. My boyfriend recovered quickly after using it for just 1-2 days, which prevented a week-long illness. I recommended it to a friend whose child and husband were infected; it worked wonders for them too. Purple Daisy has now become an essential supplement in my home. When infected, I suggest taking 2 pills every 2 hours and several times daily, especially combined with vitamin C for better results.
