I never throw away used tea bags. I let the bags or loose tea dry, then add them to a ziploc baggie of used tea. I use mine for gardening.
However, another use is to take the used green tea bags and stash them in the fridge. Apparently they make good cleansing pads for the face, as they not only help to exfoliate, but the anti-inflammatory properties can even out blotchy complexions.
Tea is awesome!
Today's mug and tea:
Green tea with ginger. This mug was a joke gift from my husband for my first Mother's Day. It says Yo Mama.
