there are so many things wrong with what you have said.
Please for your own good and before you harm yourself or someone you care about, actually learn about science, and medicine, and the history, and procedures of both.
No one (up to that point) said you were ignorant but yourself.
You are however grossly misinformed.
Nice try at the pitty wildcard.
In point, "thousands of years of research".
You do know that human beings only started to settle down about 10,000 years ago right?, and in that time we've had written language for about 5,000 years.
There are some records showing medical usage of plants dating back with those early records.
However that is not "research" that is keeping a log of things that work for certain situations.
Each record with gaps and certainly no form of consensus or controlled testing for treatments, which is a key part of medical research.
Also you have the right to be an idiot, you also have the right to be vocal with your misinformed, under and or uneducated opinions, and to parrot these things based off of flawed or no data whatsoever.
Everyone else also has the right to point out to you that you are wrong, tell you why, and then freely call you a fucking idiot to your face when you simply dig in your heals holding onto stated ignorance rather than correct a misunderstanding you held about the amazing world we live in.
