After only using 1 of the 20 pouches to "help rid my cold" my throat swoll within minutes to the point where I really thought I was going to die. It was 3am and there was no one to call but 911, luckily I was stupid enough to try and wait it out, after an hour I was able to breath normal again, and by 9am the swelling was almost completely gone. I WOULD NOT RECOMMEND THIS TO ANYONE! I don't know what triggered the attack, but it was scary for me and my family!
