science from 200 years ago is not the same thing as we have now ffs

now, and at basically any point from past hundred years or so, when scientific method was reasonably widely adopted, this method is a tool to avoid repeating mistakes like this

and at any rate it doesn't mean that random snake oil peddler, in this case "traditional medicine" flavoured, is more trustworthy than state of the art evidence based medicine, just because science made mistakes in the (distant) past
