I make a fresh batch of tea every morning and allow the herbs (that needs to be steeped for a longer period of time) to steep all day long, drinking from it continuously throughout the day.
I add a little bit of the tea (with herbs that need to be steeped for shorter period of time) to my cup.
Because licorice may have an energizing effect, I don't blend it in the tea after 3 p.m.
And because peppermint becomes bitter shortly after steeping, I usually add that separately (through a tea strainer) to my tea.
Be discerning about what kind of bake/cook ware you use. Read my Safest Cookware and Bakeware article to see what I recommend.
