We do not promote the use of tea bags due to concerns about microplastics. Many tea bags contain small amounts of plastic, which defeats the purpose of enjoying a pure herbal tea for its health benefits. That’s why we offer loose-leaf herbal blends.. For the best experience in an office or during travel, we recommend using a tea strainer or infuser. You can easily find these on Amazon. To make it convenient for office use, you can carry a small, portable tea strainer with you. For instructions on how to use it, check out this helpful video from 9:10 onwards: How to Use a Tea Strainer.
