After reading all the great reviews, I optimistically ordered some of this tea. I've had problems with sinus congestion very often this winter and have tried all kinds of remedies with little success. Unfortunately, this really didn't do anything for me. The taste is OK (bearable), but it did nothing to relieve my sinus congestion. (So far the only things I've found that have helped me somewhat are the Vicks personal warm mist humidifier and Neti Xlear)

I had to be taken to the ER in an ambulance earlier, the day before yesterday. I was having seizures, near-syncope (passing out, but still being somewhat conscious), couldn't breathe, and my blood pressure was at stroke level. I felt like and thought I was dying (or maybe already) dead for about 3 hours. It was painful and horrifying. I think I figured out what it was that caused my near-death experience. It was probably the energy-shot I took 20 minutes before then. I don't usually take something like that. Someone offered it to me, and I was so tired, I didn't even look at the bottle and took it. Please, don't use these!

These remind me of dog treats I made once using pumpkin and cinnamon. They're kind of bland and not my favorite Back To Nature product. But my finace really loves them so that's where the three stars come from.
