There are certainly more disgusting things you can use as a medical treatment than moldy bread. Sticking “mouse paste” in your mouth with the hope of relieving a toothache would be one of them! Moldy bread has a long history as a treatment, going back as far as the days of the ancient Egyptians, who would rub it on wounds. As we know today, there is indeed something to this idea, since the development of antibiotics really got started with the discovery that certain molds were able to kill bacteria.
