It´s really good stuff...it´s a natural disinfectant..like white vinegar, but I think it´s better. For instance, if I have a sore throat I dilute some ACV in warm water and gargle or even drink it (takes some getting used to to drink it). I put it in my birds´water too, as it´s supposed to help keep down nasties like worms and bacteria in general. If I have a chicken sneezing, I give it a good dose of ACV with some water. Gets them right pretty quick. I recently had a chick that got cold in the rain, silly thing. I brought it in, dosed it with ACV and the day after it was good again. One of my geese had a sore eye, so I gave it a bucket of water with ACV in, and it got better quickly....etc etc.
It´d be a good read on the net to see what more it´s good for.
