Hi, got here accidently, got fascinated. I had some boils which started out like a spider bite. I attacked it with hot water lavender poultice (very BRIEF, just to open the pores), and then a bentonite clay mix, combined with colloidal silver. This usually will take down any infection. However, it wasn't until I poured colloidal gold solution over the leg, inaddition to the bentonite, that it got cured. For open, supporating sores, etc, colloidal silver combined with zinc is quite effective. Also, to help cure the heavy metal toxicity which you said contributes, mix 1 tablespoonful high grade bentonite (or pascalite) clay in one glass of water. Drink this every other day for about eight weeks. This is an amazing remedy.
