I certainly bought the ancient remedy story. Getting wised up doesn't diminish the amazing work done with willow, and chinchona bark. Obrien writes of 'jesuits bark' a lot in his naval fiction, makes me wonder now how much the Georgian british navy did actually use this kind of thing for fever reduction.
On the whole, I'm going to give blowing willow smoke up my Anus a miss, if that's ok.

Speaking of which, here lie several drawings of people blowing smoke up a miss's ass FWIW:

While more hygienic than mouth-to-mouth resuscitation + CPR, I suspect legal complications would render the technique non-preferred today.
BTW the lady depicted in the first drawing has few, if any, clothing undergarments for a married woman of the year 1746. Indeed for any woman, any year.
