I swear by this stuff!! If you get that little scratchy feeling in your throat that usually means a cold is coming on, just put one drop on the back of your tongue - if there's any nasty germs there it will burn like crazy!! Do that a couple times a day and you'll never get the cold. Oil of oregano is a natural anti-viral and anti-bacterial and it'll kill anything!! My kids laugh cause my answer to any ailment is to use it - they say if they broke their leg I'd tell them to use oil of oregano!! LOL It'll cure any infection from a cut. People may laugh at this but it works!! Try it.
