Back in the late 70s, my family and I were living in middle Georgia and my daughter and I had somehow developed boils. Mine was on my armpit and my daughters was on her leg. I remember that year was a bad year for mites on our property and I wondered if we may have gotten bitten and infected by these critters. Anyway, I had heard that if you put "fatback" on the boil for 15 to 20 minutes that it would draw the boil to a head. It worked. I was able to squeeze the boil out and then saturate with peroxide. These things hurt really bad. Just know that it is really gross to squeeze these bad boys out but the relief is worth it.
EC: "Fatback is the layer of fat along the back of a pig, used as a cut of meat. It is often used to make lard. Fatback is a traditional part of southern U.S. cuisine and soul food, where it is used for cracklings or cracklins, and to flavor stewed vegetables such as greens and black-eyed peas. Many people enjoy eating strips of heavily salted and fried fatback, often referred to as streaked meat or streak-o-lean. Fatback was extremely popular in the South during the Great Depression because it is an inexpensive piece of meat. This dish is also widely eaten in Ukraine, where it is called salo."
