It certainly sounds like it should be more difficult than that (and as far as I, a non-medical professional, know it is) but keep in mind the pharmaceutical industry is worth billions to a select few, and keep in mind back when Eli Lilly's Twitter was hacked and posted insulin, a substance that costing some people over $1000/month just to live, would be free, their stock dropped 4.37% the next day.
Like I said, I'm no medical anything but like with previous products that have claimed to be medically beneficial, I think it's worth at least taking a step back and looking at what someone stands to gain by claiming something vital is simple versus what those who claim otherwise stand to lose.
After all, I think we've all heard the story of the doctor who, in a fit of desperation, cured his wife's cancer with bicarbonate of soda and then did so with more of his patients before being sued by Big Pharma.
