Love this tea

My husband has been drinking dandelion root tea for many years. A few months back I purchased this brand for the first time since Amazon was out of my usual brand. I purchased it from Walmart.com. Immediately after drinking the first cup of this tea, my husband got profusely sick with severe vomiting, very low blood pressure almost to the point of passing out. He ended up at the emergency room. At this point, we did not know that it was the tea that made him sick. The doctor said it must be GERD and gave him some meds. A couple of days later, he drank the tea again and the same thing happened to him again. We went back to the ER and they could not figure out what was wrong. We still had not figured out that it was the tea. The next day, my husband did not drink the tea, but I did. It was my first time ever drinking dandelion root tea. The exact same thing that happened to my husband happened to me. That is when I knew it was the tea. It was a very frightening experience as I had difficulty breathing in addition to all the other symptoms. I did not post this right away because we wanted to experiment and be absolutely sure that it was this brand. I purchased my old brand and my husband has not been sick since. This tea caused us two ER trips, missed work, and a miserable few days. Right after this happened I came on here and at Amazon to check the reviews and there were quite a few negative reviews on Amazon with the same experiences that we had. All of those reviews are now gone from Amazon so I am sure that my review will not be on here very long either.
