As part of its enforcement activities, the Food and Drug Administration sends warning letters to entities under its jurisdiction. Some letters are not posted for public view until weeks or months after they are sent. Business owners have 15 days to respond to FDA warning letters. Warning letters often are not issued until a company has been given months to years to correct problems. The FDA frequently redacts parts of warning letters posted for public view.


TeaTaze LLC


Wichita, KS

An online tea company in Kansas is on notice from the FDA for claims made about its tea’s ability to mitigate, prevent, treat, diagnose, or cure COVID-19 in people.

In a July 23 warning letter, the FDA described a review made of TeaTaze LLC website as well as the company’s Facebook page in March and April 2021.

The FDA’s inspection revealed that the firm made claims on their websites that the products are not foods, but rather drugs under section 201 of the Federal Food, Drug, and Cosmetic Act because they are intended for use in the cure, mitigation, treatment, or prevention of disease. With certain exceptions not applicable here, new drugs may not be legally introduced or delivered for introduction into interstate commerce without prior approval from the FDA. The FDA approves a new drug on the basis of scientific data and information demonstrating that the drug is safe and effective.

Examples of some of the website claims that provide evidence that the products are intended for use as drugs include:
