Although tracing its origins back to antiquity, a distinctly new kind of alchemy emerged in mid-16th-century Europe. This new tradition developed out of the teachings of Paracelsus (1493–1541), a German medical practitioner who challenged the authority of university-trained physicians. He sought to establish a reformed kind of medicine based on first-hand experience of the natural world rather than dry scholastic texts. Alchemy was at the heart of this new medicine, a body of experimental practice and theory that not only held out the promise of improving the health of individuals but could also be applied to wider sicknesses of society.
