i used to swear by it! especially when i thought i was getting an infection... then i tried oregano oil which has even stronger properties and i was converted. I still use it from time to time on top of oregano when i need an extra boost. Just be sure you get a brand that has a high concentration of the extract because there are a lot of companies on the market trying to sell a product that is so diluted that it does little good. Def. worth a try though (oh but beware of the taste!)
