There is no evidence that Echinacea or any other ingredient in herbal medicine can prevent or cure severe respiratory illnesses, including COVID-19. The scientists who issued the warning also caution that the product could be dangerous to people with autoimmune conditions. The study has also not been peer-reviewed, and it does not, by any means, show that Echinacea can help cure COVID-19. Moreover, the researchers had only tested the product on cell lines and virus particles, not people. However, other scientists warn that this limited investigation did not look into the effect of the product on the virus that causes coronavirus disease 19 (COVID-19). Meanwhile, a study from 2020 indicates that a commercial product containing Echinacea extract could help prevent severe respiratory diseases caused by coronaviruses. However, they point out that the lack of standardization among Echinacea products may keep people from finding effective remedies. In 2011, the authors of a review found that some extracts of Echinacea may help treat viral respiratory infections. Researchers have yet to prove that Echinacea can reduce the impact of a cold, and there is very little evidence that it can help with other illnesses.
