I remember reading how if you steep tea for too long a lot of the toxins and stuff seeps out and also a lot of tea is grown in areas where the soil contains lead and gets into the tea which sucks because how can you know
There was a story that came out recently about those triangle/metallic-type tea bags are releasing tons of microplastics into your tea when the water is hot. So not exactly the ones in the photo because they’re paper, but still. Topical joke
For real though, I should look into this. I've been enjoying some herbal tea at night. Mostly rooibos, but some ginger tumeric that smells like feet, but tasty feet.
