Originally published at Leipzig in 1633 without the three added treatises. This Geneva edition, edited by Johann Michaelis and Georg Evrard Hartmann, son of the author, was also issued with a variant publisher statement (sumptibus Petri Chouët) but identical collation.

Johann Hartmann was the first professor to hold a chair of chemistry in Europe, at the University of Marburg in Germany. His Praxis chymiatrica gathers his lesson on chemistry and alchemical medicine and deals with the treatment of various diseases: diabetes, epilepsy, gangrene, humors, melancholy, plague, tumors, apoplexy, paralysis, aphtha, angina, nausea, dysentery, etc.

The volume also includes: the Tractatus de oleis variis arte chymica destillatis by Johann Ernesti Burggrav (pp. 397-594); the Basilica antimonij by Hamer Poppius (pp. [595]-631); and the Methodus, qua omnes humani corporis affectiones ab humoribus copia, vel qualitate peccantibus genitae by Marco Cornacchini, which occupies the final section of the volume (pp. 112, [16]). The last two works opens with a half title. All three treatises had been previously published separately. The four folded leaves of tables are in Cornacchini's treatise.
