Supposedly one of the first distillation manuals of various medicinal waters was Von allen geprenten Wassern (or Von den ausgebrannten Wassern) by Austrian Michael Puff von Schrick circa 1450s but in many editions and incorporated into later Brunschweg etc. I can find images of it online but not a text form that I can try to at least run through Google translate. Wondering if anyone else has seen it in that form; I have failed repeatedly over the years.
Here’s a PDF
