i tried it and am still living i think. its probably broad spectrum and somewhat effective vs many diff organism including beneficial bacteria so something to keep in mind. i bought the Diamond G product for internal use and i tried the can of the other stuff (was about $9 for a quart iirc dlv thru Amazon) for soaking my toes in for toenail fungus (didnt work)
i just bought some Sugar cubes to try the internal method again.
