In a previous post, which I'm going to take down, I recommended this mixture (Oxine and citric Acid) as it was recommended to me as cure for white line disease and thrush. I've read that many are having a good success rate with treating some hoof condition with it.
But I've had some negative experiences with it. And I'm not longer recommending it. In fact I'm warning against it's use as I do bleach or any other chemical treatments of hooves.
1. It didn't touch the white line infection on my gelding.
2. I used it on a founder mare's thrushy frogs and it cured the thrush and destroyed her frogs.
3. I took a whiff of the mixture after it was diluted and it burned my throat and caused me to feel like I was going to pass out.
This is solution that I've read it used for santising restaurant kitchens and practitioners have been using, apparently with success on some cases of white line.
But it is strong, scary stuff and should not be mixed in an enclosed area. It's being recommended by some very experienced professional hoof care practitioners, but I'm concerned that it will kill live tissue along with bad bacteria. I doubt anyone has done that type of a study on it.
So please don't use it on your horses. As a cleaner, it probably works well, but as with any cleaner, don't breath it!
I apologize for recommending it before testing it myself.
