prosperous,
urine was applied each time it started to irritate. when i say 18 months it took that time to completely irradicate it.in fact one of my ears (inner that is) cleared up a lot quicker than that. the other was much less irritating at that time,
but it wanted to flare up from time to time,so i kept going until it was gone.
so my friend it wasn't a daily DOSE so to speak it was the ghastly itching i treated. perhaps if it were done on a daily basis it might of healed a lot quicker.
i suppose if it were VISUAL i think i might have done that, perhaps someone might have the answer to DOSAGE, i hope that helps you a bit anyway,thanks, Tom.
