I drink a cup of chaga tea every day. Heres a few pieces I have now. This is enough to last 5 months at least. Its best if you let it dry before you use it. That takes a week or so. Store it in paper bags, not plastic. I live in North west Pa. and I can find this very easily. Birch trees near streams or creeks is the best place to look. Only take chaga from live birch.
