Also took a metabolic supplement whose main ingredient was green tea. It took about a month but I did have a severe allergic reaction with hives & extremely intense pain. Took antihistimine & applied Cordaid for itch. Stop this supplement & it symptoms went away. However, I still drank the tea but still seem to get the welts & itch but much smaller around ankles. I enjoy it so as it seems to energize me. What to do, stop?
