Of course we know there is a lot of potentially useful knowledge that came through practice over thousands of years. As I said, it is not useful to be right about things when you are also wrong a lot and you can't tell which things are wrong and which are right. Science gives us a way to sort wrong from right. Traditional medicine takes millenia of observation to arrive at simplest things that then can be easily forgotten or misused. Our "regular" medicine might be wrong a lot and sometimes might even be taking steps back. But overall it is moving in the right direction at a truly lightning speed. It only seem slow to us because of our impatience but, objectively, it has done gigantic progress within just one generation. Personally the more pressing matter is figuring out a way to make the state of the art medicine available to everybody.
