The FDA has issued warning letters to two companies — Griffo Botanicals and Prairie Dawn Herbs — telling them to stop promoting non-FDA-approved herbal products "to mitigate, prevent, treat, diagnose, or cure COVID-19."
These letters include this language:
FDA is advising consumers not to purchase or use certain products that have not been approved, cleared, or authorized by FDA and that are being misleadingly represented as safe and/or effective for the treatment or prevention of COVID-19. Your firm will be added to a published list on FDA’s website of firms and websites that have received warning letters from FDA concerning the sale or distribution of COVID-19 related products in violation of the FD&C Act. This list can be found at http://www.fda.gov/consumers/health-fraud-scams/fraudulent-coronavirus-disease-covid-19-products.
