Big pharma is not likely to fund a study about how to treat disease with garden plants that people can grow for free, are they?
No, 50% correct. Big pharma will not fund a study for any drug they can not
patent. That's where universities and research hospitals need to jump in.
And sometimes they do. Sometimes, those studies are about homeopathic remedies. The more methodologically sound the study, the closer the effects of homeopathic remedies are to placebos, which isn't surprising, because there are no active ingredients left in homeopathic remedies once they are diluted.
Some naturopathic remedies have medicinal value. Some don't. As Chemgal pointed out, many drugs we use are derived from plants as well. Do you know why they are considered drugs and not "naturopathic remedies"? Because they were proven to work. A lot of stuff that falls under naturopathy is quackery, like homeopathy, but not all. We know some plant extracts have medicinal properties, and they are not regulated, so they are the domain of naturopathic doctors and some medical doctors who delve into those solutions. But homeopathy is all bulls**t.
We helped fundraising efforts to study the use of an old diabetes drug for brain injury repair. Drug companies are not interested, because the patent long expired. Sick Kids is working on it.
FFS, people. There are scientists trying to heal children's brains. There are scientists for big pharma, doing good work in areas that are patentable. Yes, people want to make money, but is it not better that diseases are cured and some people make billions as a result, than the disease is not cured at all? Regulatory bodies try to do their part. I've been around as my wife tried to clear FDA hurdles. They aren't trivial. Yes, some companies cut corners. Yes, some try to fudge results and ignore side effects. It's not a perfect system, but it's the best we've got,
and far more people are alive than dead because of it.
