spagyrist
An alchemist, especially one who tried to discover remedies for diseases.
It has, of late more particularly, assumed not only an unforbidding, but even an engaging form, by the facility with which many of its most important researches are now conducted, and by the extension of them to numerous objects which had not before been attended to by the old spagyrists.
Where it comes from
From modern Latin spagirista, from spagiricus (“alchemy”) (probably invented by Paracelsus).
