my kids seem to get every sickness that comes along, but i have found that if i get the patches on them at the first hint of sickness it draws the nasty viruses right out. i have done this for myself and my husband as well. it works especially well for stomach bugs. if you catch a cold at the very first sign of a cough or stuffy nose then it takes that right out too, but if you wait til the symptoms are more pronounced then the cold/flu runs it's course just they don't get quite as sick if the patches have been used. this product is well worth the money and i don't like to be without it.
