I believe this is a worthwhile topic for at least part of a permanent article in the Tea Guardian. You are not the only one with the water retention problem in the lower legs.
The allergic reaction when you have tea prepared from the tap water, however, should be watched out. I am not sure whether it is chlorine or something else in the water that reacts with tea to form compounds that is bad for you. I advise using an efficient filter system for your water even for other purposes. I have no first person experience with the water in any locations in South America so I really cannot be very specific, but I have seen different water forming various stuffs with tea and none would cause allergies, unless the water is polluted.
I’ll put the water retention topic in my list of articles that I promised readers (and that’s a long list). Meanwhile pls read detail article on water at this link:
