Hi, Sharie, A friend of mine used Tetrasil successfully to get rid of a skin tumor. But it took 3 to 4 applications each day for about 3 weeks to get noticeable results. It might be a gentle alternative to zinc chloride-based black salve. Also, it would be an interesting experiment to compare Tetrasil to silver sulfate ointment, an old remedy still in use in some parts of the world. It might be possible to make silver sulfate by electrolysis with dilute sulfuric acid.
