I had read about this and it works. I had a boil in my groin area that was painful and hard. I applied some campho phenique to the bandage part of a large Band-Aid and slept with it applied to the boil all night. You might want to apply sterile gauze over this due to drainage. The next morning pus had began to flow freely. Gentle squeezes from the base of boil will cause more to be released. Continue this treatment until the boil gets small or is gone. I used Tylenol for the pain I was experiencing. Sometimes low iron deficiencies cause boils so I will begin eating a handful of raisins a day which is suppose to prevent them.
