Echinacea protects against viruses in general, not against SARS-CoV-2 in particular
During flu season, when respiratory viruses are flying around, there may be something to be said for supplementing with echinacea. But if you specifically want to protect yourself against the coronavirus SARS-CoV-2, echinacea may be less suitable. This is suggested by a sponsored human study that appeared in Frontiers in Pharmacology in 2022.
Study
Echinaforce contains an extract on a 65 percent alcohol base from material consisting of 95 percent aerial parts of the echinacea plant and 5 percent roots.
One Echinaforce tablet contains 400 milligrams of echinacea extract. The study participants therefore took 800 milligrams of extract per intake, 2400 milligrams per day. When the subjects came down with a cold or flu, they took a dose of echinacea 5 times a day. This amounted to 4000 milligrams per day.
After the study participants took echinacea for 2 months, they left their supplements for a week.
Subjects in the control group did not take any supplements [Control]. They also didn't use a placebo.
Results
Click on the table below for a larger version.
Supplementation with echinacea reduced the number of days that subjects suffered from a virus. You can see this in the table above.
The subjects in the echinacea group also lost fewer sick days as a result of an infection with the specific coronavirus SARS-CoV-2, but again the difference was not statistically significant.
