That's the problem though - the scientific community put most of the naturopathic theories straight in the bin as "hogwash", and conversely the naturopathic community are completely against drug treatments. If only they would find a way to meet in the middle, they'd probably cure everything! I've found, from experience, that sometimes natural remedies work very well, and sometimes there's a logical (scientific) explanation, but other times there's an unsatisfactory explanation ....... but that's not to say it doesn't work, it's just poorly understood. If memory serves, the reason why digestive enzymes and ACV work for some people is thought to be that they may have an underproduction (hypochlorhydria) of stomach acid.
I also believe that perhaps some of us have undetectable Helicobacter or some other bug (after all Helicobacter isn't the only bug around) and the ACV, manuka honey and mastica gum type remedies may help because they are reducing the numbers of unfriendly bacteria ........ so many theories ......... and so much of the research aimed at drug cures rather than causes .......... ho hum... go climb of soap box now.........
