Apple Cider Vinegar can help to make the boil go away and prevent further infection of the boil.
Soak a cotton ball in the apple cider vinegar and apply it to the boil and wrap some medical tape over the cotton ball to let the apple cider vinegar work on the boil.
You can also just apply some apple cider vinegar directly to the boil if you want too and it will help since apple cider vinegar is anti inflammatory and antibacterial.
Another home remedy to get rid of a boil is to apply warm compresses and soak the boil in warm water which will decrease the pain and help draw the pus to the surface.
The boil should then begin draining and you can then wash it with an antibacterial soap until all the pus is gone and clean with rubbing alcohol.
Never pop the boil with a needle as it can cause infections and make the boil worse.
