10 Mar 2020 --- The US Food and Drug Administration (FDA) and the Federal Trade Commission (FTC) have warned seven companies for selling products claiming to prevent or treat COVID-19. The offerings include teas, essential oils, tinctures and colloidal silver, with the companies now subject to legal action, including but not limited to seizure or injunction. The FDA is concerned that products that claim to cure, treat or prevent serious diseases like COVID-19 may cause consumers to delay or stop appropriate medical treatment, leading to serious and life-threatening harm.
