Iodine

You don't have staph infection unless it's been clinically diagnosed by an MD.

I used to get a boil or two - pre WWII - before antibiotics.

Simple home treatment.  Keep it clean.  Lots of iodine on the boil and open sore.  Lots of gauze on the wound - and allow some air through the gauze to the boil.  Change bandage and apply iodine daily.  It will drain, come to a head, ooze some at first, and then heal.  Takes a week or ten days.

Never went to a doctor.  Couldn't afford the $1 office visit.  Almost all remedies in those days were home remedies and mother nurse knew all of them.
