“Natural remedies work against the crown!” This was the BLICK headline on September 13, 2020, and many other outlets around the world reported on the effects of Echinaforce. At that time, the renowned Spiez Laboratory demonstrated the antiviral effect of the preparation with a study. At least in the Petri dish, it has yet to be tested in humans.
The maker of Thurgau A. Vogel was on everyone’s lips, people ran to pharmacies and bought the shares of Echinaforce. Now the researchers have rowed again. The researchers published a correction to the original study in the journal “Virology.” The researchers write, on the one hand, “that all the hypotheses that have been made about the effect of Echinaforce in humans against Sars-CoV-2 are theories that have to be tested in clinical studies.”
Direct contact required
Most importantly: “We would like to emphasize that virus killing activity requires direct contact with the virus particles and the Echinaforce solution. But since Echinaforce is taken orally, it is unclear how relevant this effect is to humans.
Bottom line: It’s unclear to the authors whether Echinaforce is helpful against Corona.
The authors were also able to refute a criticism of the study. When it was published, some experts suspected that the ethanol solution used killed the virus and not Echinaforce itself. The researchers conducted new tests and concluded that ethanol had no significant effect on viruses. (vof)
