As a young child I remember having a sore, ugly boil on the inside of my arm. Our family visited relatives for a weekend and my great-auntie Em applied something called black drawing salve on the boil. In the morning my Dad gently and patiently squeezed the boil like one would a pimple. The inside of the boil slowly came out just like a pimple would ooze. Life marched on and about 60 years later I tripped over a "recipe" for black drawing salve. This took me back to that
