^Sounds like good ol' ginger tea to me. I tend to grind it up too and then strain it. More intense. When I'm lazy, I just use ginger slices (maybe "bashed" slighty).
Gonna have a hot toddy now. 3 oz Monkey Shoulder, 1-2 tsp cider vinegar, 2 tsp honey, half a cinnamon stick, 1 star anise, 3 cloves, a few slices of ginger and a few "grains" of cardamom (the stuff inside the pods). Heated up, strained, diluted with 4.5-6 oz boiling water and kept warm in a "baine-marie".
