The scarce first edition of this popular compendium of medico-chemical remedies cum book of secrets. Hadrian Mynsicht (1603-38) was a German physician and chemist trained at Helmstadt, later personal doctor to sundry noblemen, including the Duke of Mecklenburg. Part book of secrets part pharmacopoeia, Thesaurus contains a description of the preparation of a number of medicines discovered by Mynsicht and still in use, in 1751, by the apothecaries. He was the first to prepare tartar emetic from roasted antimony sulphide and cream of tartar (Ferguson). Whilst following iatrochemical theories, i.e., the interpretation and study of medicine and physiology in chemical terms, Mynsicht also included a few Hermetic processes such as how to obtain the Philosopher's Stone, as well as, Unicornus solare, Luna potabilis and Liquor Solis aromaticus, from minerals. Each section presents a substance, one or more recipes to obtain it, and under Vires, Usus, Dosis (strength, use, dosage) its effects for specific conditions and types of patients (e.g., virgins and young women ). Among the sources cited are Du Chesne, Croll and Libavius. Mynsicht explains how to extract dozens of kinds of quintessence, pills, electuaries, balms, therapeutic wines, syrups and oils, e.g., from cinnamon, coral, deer antlers, as well as powders to treat epilepsy, gonorrhoea, incontinence, piles, impotence, teeth whitening (using Farina virginea), menstrual pain (with laudanum), fevers, backache, kidney stones, insomnia, the plague, gout, melancholy, mania, apoplexy, etc. Part II, called Testamentum Hadrianeum , reprises both the genres of the testament , used by alchemical and iatrochemical authors such as Paracelsus, Llull and Basil Valentin, and allegorical alchemical verse, being a Latin poem on the making of the Philosopher s Stone, prefaced by one page on Hermes Trismegistus. An interesting work suspended between competing chemical theories.
