Could the toothpaste be Tea Tree oil with baking powder?
Amazingly, just three tubes of Toothpaste that has a Mint in it- spread all over the body (even on your head scalp ) gets in DEEP into your pores to kill that bacteria. A Boil (or furuncle) is a deep infective folliculitis (infection of the hair follicle). Spread it all over the body like a soap & wait till you feel the little bit of burning sensations & bit of sting feeling by the mint ('till you can hold). Then Rinse. If you can't hold rinse it immediately & do that for Three-five consecutive days. Your fungus infected skin sheds & will start to look softer & prevent Boil from reoccuring. Good luck.
