For thousands of years ppl have done whatever they could to fix what ails them and their animals and they SWORE by it. But you know when I have migraine I don't drill a hole in my head, I take a Tylenol. People are living longer than ever because there were willing to learn and use more and more modern treatment methods.
While your animals my have survived and recovered with the treatments you described above, many of the methods you mentioned have been proven to not be the best or most effective method. Nothing helps RI like antibiotics, period. Antibiotics kill RI bacteria.
