All my life I have suffered from upper-respiratory infections, everything from pneumonia, bronchitis to tonsilitis to simple colds. I could never be in the same room with someone that was coughing and sneezing without catching it myself, ever. For 20 years of marriage, if my husband caught a cold, there was never any doubt that within a couple of days, I would get sick with it. As a singer-songwriter, I dreaded it, because it would naturally directly affect my vocals. I've been that way my entire life, 53 years. Then I started drinking your Hibiscus-Lime tea this year. Twice now, my husband has come home sick, coughing, blowing his nose, and even sleeping in the same bed with him, a foot away, I have yet to catch his colds! It's been amazing. I'm trying to convince him, a hard-core coffee drinker, to drink this Hibsicus Mate, and anyone else within earshot, especially with the winter season here. I just ordered 3 more boxes.
