Cut the end off of a white potato
Use a sharp edge knife, and scrape the white of the potato until you get a soft mushy white pulp
Put some of the white mushy potato pulp in the center of a bandaide, and apply the bandaide over the boil.
Repeat this once in the morning, and again at night
Put the leftover potato in the fridge for use in the next application.
Just cut the exposed part of the potato off to reveal fresh white potato for next use.
The pulp in the bandaid will be blackened when removed. that is from the bacteria and toxins it has drawn out of the boil.
This is the best and guaranteed method :)
