I totally agree with a lot of the points you make (seems we're not so dissimilar) and am sorry there are fraudsters in the alternative area, and your mother was personally affected. I agree, most alternatives are a waste of time as I've tried many myself.
However, I would think there must be a correlation between modern toxic exposure and mental, as well as physical, health.
Niacin is only one of many alternative protocols but the best I've personnally experienced.
I agree with you about modern medicine, oftentimes it can be excellent.
