On May 26, 2020, the FDA issued warning letters to four companies for selling products such as CBD, essential oils, colloidal silver, and vitamins with unsupported claims that they can treat coronavirus (COVID-19).

The agency emphasized that there are currently no approved treatments for the virus and has previously stated: "There currently are no vaccines, pills, potions, lotions, lozenges or other prescription or over-the-counter products available to treat or cure coronavirus disease 2019 (COVID-19).

Companies that received a warning letter include the following (use the links below to read the full warning letter):
  • CBD Gaze (Restorative Botanicals Ultra High Strength Hemp Oil Supplement and Serenity Hemp Liquid Dietary Supplement)

  • Alternavita (grapefruit seed extract, colostrum, and cod liver oil products)

  • (colloidal silver, vitamins, minerals, herb oils and a homeopathic drug product)

  • Careful Cents, LLC (essential oil products)

Products were promoted with statements such as "Let the power of CBD help you combat your illness, covid-19, coronavirus," "HOW TO PREVENT CORONAVIRUS... Have common immune boosters on hand... Stock up on... colloidal silver," and "Can you use essential oils to boost your immune system and fight coronavirus? Yes!"

The agencies instructed the companies to send an email to within 48 hours of receipt of the warning, describing the specific steps they have taken to correct these violations.
