So I'll limit myself to the original point.
Science, particularly modern science, even with all its baggage and flaws and politics, is evidence based.
Evidence in this case is statistics and data. Those are not present, from many reasons (as an aside, I don't think there is any evidence of statistical trials being performed in the Vedas).
There is no work in medicine in the Vedas that satisfies this criteria. Ergo, it is not yet evidence based science. It's observational. Now, if the govt. through AYUSH [AYUSH added in edit] actually invests in performing clinical trials etc. and publishing them in peer reviewed journals, then your argument may hold water. You are conflating correlations with causation / evidence.
