★★★★☆
1 generous pinch of borax + 1 generous pinch of epsom salt + just enough water to dissolve (maybe 3 or 4 drops). I have mixed this solution in the palm of my hand and applied. Reapply as needed throughout the day. For me, the first application greatly reduced pain and inflammation. It softened the hard inner part of my boil and flattened the angry, tender to the touch surrounding area within hours. I've had to reapply twice in a couple of days because it hasn't completely disappeared. Maybe if I had reapplied a few times in one day, I may have obliterated the evil awful boil? Maybe.
I also have 1000mg/1G turmeric. I took 2 of those today for good measure.
