I've read that licorice root shouldn't be used for a long period of time, but I didn't think that 10 days was that long. I guess teas are a lot stronger then I thought. They don't even mention how to properly use herbs on the website:
Thanx FF for bringing this to my attention. Without someone like you, I'd just keep scratching me head: "Hmmm, this doesn't seem normal! Geee?" I was actually going to get the red raspberry tea in bulk instead, but I didn't have enough $, so I went with the licorice because it smelled good.
