This pills madness is a marketing, from my point of view and from what I have seen, some pills are making it worse ... unfortunatelly, the pills are not working the same for all the pacients.
And is easier to give some medicine than to find a different way to "cure".
You are correct. Chemical medicine is one of several ways to treat diseases, but arrogance prevents considering them. Chemical medicine has a monopoly and it is just disgusting.
