A UAB research has characterised in detail how polymer-based commercial tea bags release millions of nanoplastics and microplastics when infused. The study shows for the first time the capacity of these particles to be absorbed by human intestinal cells, and are thus able to reach the bloodstream and spread throughout the body.
Problem solved. It really is better once you get in the habit of using one. Especially if you like a tisane as well, dried peppermint leaves and other herbs in bulk cost like 5% the price of the bag version.
I like this one, because there’s no moving parts and no chance of it popping open and letting loose leaves out into my cup.
