I got some of this tea and love it so much. The other day after drinking quite a lot of it over a few days I noticed that I was bevoming itchier than usual, especially my eyes. My left eye began to weep with gooey stuff. The next morning my eyes, especially my left one were covered with crusty 'sleep'. This has also happened when I have soaked my feet in a basin of Bentonite clay. Is this gunk coming out? And if so what would it be?
