1. Disinfect the boil with peroxide every day.
2. Put natural thick honey on the boil & cover with a band-aid.
It's best to do this every morning and evening,in that order.
Another remedy is to heat some milk so it's not hot but sharply warm. Put a piece of bread in the milk and gently squeeze it and place on the boil.It will hurt for a few seconds. Leave it on for awhile. Repeat as often as needed with more pieces of bread. It draws out infection and the red circle around the boil will get smaller. Both remedies worked for me.
