That's the one. I think Richard Schultz has a variation of it. Probably even better if you could make your own with fresh herbs and lay it on as poultices, and somewhere on the Dr. Christopher site there is a formula, but the quicky kind takes two weeks and the more potent kind has to be set out at a particular cycle of the moon and takes several months to "cure" as I recall. But the constitutional hydrotherapy with electrotherapy extraordinary, also. I met a man who had diabetic gangrene and was scheduled for a full leg amputation, and this therapy saved the leg. It saved me in a different way.
