Probably just an attempt to discourage people from doing anything natural.
This would be in the interest of pharma and the medical profession.
Lots of it on the web.
The best way to do what is being done there is to layer truth with lies and lean it towards a discouraging direction.
If they just came out and ranted against something natural with a bunch of lies then people would just discredit it as bunk.
So enough truth layered in, keeps people in there enough to believe what is being presented.
Doc is familiar with this.
Clearly its working since someone is asking if its believable.
