The only 'original injury' the infection hypothesis needs is an infection by some bug that simply turns off the immune system. There's proof that gliding bacteria can do this with capnine, and that gliding bacteria are wide spread. Once the immune system is off, you are prey to the common infections such as Borrelia, Babesia, Bartonella, as well as whatever is being coughed up the folks around you.
The term 'various injuries' would have to be more well defined for me to judge whether or not these injuries are common enough to cause anything like the diabetes epidemic we are seeing.
And, in any case, the betaine hcl is preventative, not curative, once an infection has settled in.
So you got lucky, and everyone else should disregard the evidence and take the crap-shoot that you did?
No, thanks. Natural means cure infections faster than any man made antibiotic, and the closest thing to a side effect they produce is an occasional bad taste in your mouth, as opposed to the total havoc that the antibiotics wreak on your digestion, and your immune system.
