I haven't really used it for myself but I know my friend used it several times.. I use it mostly for rescue animals for things like urinary tract infections or respiratory things. I'm pretty sure that's what they used to give my friend all of the time that had something wrong with her lungs. She always got bronchitis and pneumonia. I think that's what the doctor gave her. But I've only personally used it for dogs. It is also a good antibacterial for dog or animals with skin type infections -bacterial. It works really well in my dogs.
