Over all my years with MS and reading about alternative therapies, vitamins, etc. etc., what I have learned is that so many of the snake oil salesmen or others without evidence to support the product they're selling market it by seemingly making bland and vague associations between how their product affects the body and what happens in the disease process. It all begins to sound very reasonable and "makes sense". Of course 99.999999% of all the things being sold do absolutely nothing for MS.
I have learned that I prefer to rely on unbiased evidence of an ACTUAL connection between the treatment and its impact on the disease than on "gut feeling" or anything else. It's just too easy to bamboozle or confuse us with medical jargon when we're really not adequately trained to truly understand the technicalities of what's going on and assess it scientifically ourselves.
That's just how I've come to feel after many many disappointments over the years and a much lighter wallet.
I just know that it's too easy to appeal to my "common sense" when I really don't have the expertise or technical capabilities to really understand what I need to in order to properly evaluate what's being presented to me.
