More a time of "Herbal Remedies", I suspect. Which means that it will have:
- Things that genuinely help, like teas made with certain types of bark that we now know supply medicinally beneficial compounds
- Placebos that nonetheless help because if the Wise Woman is telling you to take it (oh, and incidentally keep tucked up warm in bed), you're going to be Ok
- A number of quack remedies that are actually harmful, but are as often as not not as deadly as life in general, that anyone notices, or produce 'bad effects that are useful', like emetics
- Real off-the-wall stuff that these days (if not then) would be considered recreational mind-benders (and may help, hinder or otherwise distract from the normal recovery process).
I think we're before the "take this Antimony pill, and when it passes through your system you can wash it off and take it again" age of medicine, but without a collegiate system governing medicine, trial and error and personal learning with a
little bit of inter-medic information exchange (which is what DF's skill system is currently made for!) is probably the overwhelming method of assessing treatment regimes. Which means a few tried-and-tested (and not outright and immediately fatal) methods is going to be the order of the day.
In some ways, I'm surprised about the use of soap, in this era. I know soap has been made (and used) for a long time, but (and I'm probably wrong about this) my knowledge of medical history seems to suggest that antisepsis precautions don't stretch that far back.
Of course, it could have been a lost art, that had been active at a DF-equivalent point of history but lost when the dynamics of knowledge changed. Those very same Wise Women probably knew not to help deliver babies without cleaning their hands, and one of the 'early' pieces of evidence for the need for cleanliness was comparison of the ongoing welfare of delivering mothers and their babies between a female/nurse-staffed location and a male/doctor-staffed location, with the doctors having frequently come straight from the morgue where they'd been 'anatomising' recently deceased. Including recently deceased women having died after childbirth from infections doubtless caught from the same cohort of doctors...
But back to DF, if they can't have the likes of carbolic vaporises, I doubt they'll get anywhere near the likes of antibiotics. Though perhaps maggots being for wound-cleaning, and leaches to provide enzymes to assist fine tissue repair, given how these fairly recent re-emergences were doubtless (before being discarded or misunderstood by a whole swathe of medical generations) used with great effect by those providing practical healthcare in the pre-industrial world.
