if the boils open, my grandmother always said take a slice of potato and place it directly on it. garlic or onion would work too apparently. she also had this one about a wart, wrap the area in tinfoil on a full moon and throw a potato over your left shoulder. don't know if that one works, but i'm Irish so i think thats where that came from lol.
you could also have a warm damp face cloth, place some epsom salt in it, and place it on the boil for 30 minutes 3 times a day if the soar is closed.
another one for if it's open, apple cider vinegar. burns like crazy, cuz it's disinfecting, so dilute it with water.
i'm guessing there's others, but thats all i know. oh, and be sure to wash your hands before and after touching it, and you shouldn't try popping it.
