Is there solid evidence that echinacea helps strengthen the lungs?

Echinacea, a plant also known as purple coneflower, is sold as an over-the-counter remedy for the common cold or flu. “Taking echinacea might slightly reduce your chances of catching a cold,” according to the National Institutes of Health, but the plant hasn't been shown to shorten its length.

There are few studies about echinacea’s effects on the lungs or other parts of the body. While it has been widely used for centuries for various ailments, the NIH notes there isn’t enough evidence of other benefits beyond its possible effect on colds. In rare cases people have experienced shortness of breath as a side effect, and people with asthma and allergies are at increased risk of such an adverse reaction.

Given the plant’s known properties, a December 2020 paper by researchers focused on natural remedies says “further research is warranted” into its potential against COVID-19.

We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs.
