A DRAWING SALVE

My Grandpa made a salve many years ago that had powerful drawing power.  It could pull out a bee stinger, a splinter, or a nasty infection. It had yellow dock, plantain, and burdock, and pine pitch in it, but it also had a lot of animal products. I would like to find a drawing salve recipe that is all plant based.  Does anyone have one to share? Thanks, Betty.
