Thanks Ws. I did post a link that sells them at $20. for a month's worth. I seriously think it has some merit, I mean the idea of this thing. There is such a thing as a drawing slave used for boils that I believe works on the same premise. I remember having a boil once when I was a kid and my Mum used it on me. We were able to pull out the core after the salve had been on it for a day or two. Then it immediately improved. I'll never forget that. It was like a long, beaded string she pulled out with tweezers. I watched the boil go down immediately. It must coil around inside it. Boils are Nasty things.
