[YEA] FWIW, I had recurrent boils for much of my life, rarely being entirely free of them. When I was in my forties, someone told me about raisins. I tried them (eating perhaps a couple of tablespoons full in muesli/granola, since I dislike the taste of raisins by themselves), and that prevented further boils almost entirely.
After my hysterectomy, the boils pretty much went away on their own, so there is apparently a hormonal component too. That is supported also by the fact that the boils were usually worse around the time of my period.
