Long-time readers know that my “go-to” sources for natural medicines (herbs, vitamins, and supplements) are ConsumerLab.com and Natural Medicines(TM). ConsumerLab has posted about coronavirus and echinacea:
Studies in laboratories (but not in people) have shown that certain species of echinacea may inhibit coronaviruses.
However, there is no evidence at this time that taking this or any other echinacea product can prevent or treat coronavirus infections in people.
A laboratory study that has not yet been peer-reviewed or published found that a particular branded form of echinacea inhibited specific coronaviruses, including (HCoV) 229E, MERS- and SARS-CoVs, and the researchers suggested it could potentially have a similar effect on SARS-CoV-2, the coronavirus that causes COVID-19, although it was not tested.
The study was funded by a distributor of the product and authored, in part, by an employee of the manufacturer.
Clinical trials of echinacea suggest a possible modest benefit for other types of viral respiratory infections, like colds, although results have been mixed, at best.
In addition, as shown in tests by ConsumerLab, the amounts of potentially beneficial compounds vary widely across products.
ConsumerLab has tested and reviewed many echinacea supplements on the market (including the product noted above for its inhibition of viruses in a laboratory). You can find its reviews and Top Picks in its Echinacea Supplements Review, which contains additional information about using echinacea, its benefits, dosing, and potential side effects.
Of course, the most important thing you can do to avoid infection with coronavirus is to prevent exposure by following the latest recommendations of the CDC and World Health Organization and take steps to stay healthy, including getting adequate sleep, keeping up with your daily exercise, and eating a healthy nutritious diet.
