This is what does wonders for boils for me, All though it has been a few years since I had one. Saturate a qtip with tee tree oil and put it on the boil and around it.The tea tree oil goes in there and kills the bacteria, it doesnt matter if it is open or not, it will penetrate the skin. Do this several times a day. Also a gauze or any cloth that will hold water, Put some epsom salt in warm water and soak the cloth in it, wring it out some and place it on the boil. cover it with something just to hold it in place,you only need to do this a couple of times.This really worked fast.
I Enjoy reading this list, thank you all for all your good ideas and tried and true advice. And oh what wonderful characters (all good) I have met here. Annice
