Hibiscus Tea is supposed to be good for the kidneys. I don’t have the proof from the blood tests yet but I can tell the difference. There is a major improvement in bladder control. Those of you that have birthed children understand what I mean. It is not perfumy ( is that a word)? Some of our teas here in the US have had extra flavor added to them. And it is not always good, you might as well spray cologne in your mouth. Anyway will keep you posted.
