I do think VetRX has oregano oil in it doesn't it? While not actually an antibiotic like a prescription drug, it is a natural antibiotic. I've actually seen several articles lately on using it in chickens and that it even kills resistant MRSA. So I think there is more to it, but otherwise I totally agree. Here is one of those articles, but there are many others http://grist.org/list/chicken-farmers-replace-antibiotics-with-oregano-oil/
