I'd recommend acquiring an early (pre 1920s) medical dictionary. These are often available at old book sales or you can buy online via second-hand shops such as AbeBooks. These will give a good snapshot of the knowledge at the time. I would be hesitant though to use any of the remedies!
Online options are to Google the term or try an online medical dictionaries are available although most do not contain the old terms.
One place that does is Rudy's List of Archaic Terms which is very comprehensive and best of all has lists of terms in a variety of other languages. He is very interested in any new terms you may have that are not on his site. Well worth a visit.
