Apple Cider Vinegar and Cyst Healing... Anyone else tried it?

So I started putting Apple Cider Vinegar onto the absorbent part of band-aids and applying them to cysts or stubborn pimples and it seems to be drying them up. I leave it on for anywhere from 15 to 30 minutes and then remove it and let the air get to it and allow it to dry. I haven't decided if it is a good thing or a bad thing yet as its great for clearing cysts, even deep ones, but it seems to bring up a lot of blood and clear stuff which causes a big nasty scab. Has anyone else tried this or had success with other techniques involving ACV?
