Paracelsus - Renaissance Magic and Medicine - Alchemist

Paracelsus pioneered the use of chemicals and minerals in medicine. His hermetical views were that sickness and health in the body relied on the harmony of man (microcosm) and Nature (macrocosm). He took an approach different from those before him, using this analogy not in the manner of soul-purification but in the manner that humans must have certain balances of minerals in their bodies, and that certain illnesses of the body had chemical remedies that could cure them. (Debus & Multhauf, p. 6-12)
As a result of this hermetical idea of harmony, the universe's macrocosm was represented in every person as a microcosm. According to the insights at the time, there were Seven planets on the sky, Seven metals on Earth and Seven centers (or major organs) in Man — seven was a special number. Everything was heavenly and closely interrelated (see table).
Diseases were caused by poisons brought here from the stars. But 'poisons' were not necessarily something negative, in part because related substances interacted, in part because only the dose determined if a substance was poisonous or not. Evil could expel evil. Therefore, poisons could have beneficial medical effects. Because everything in the universe was interrelated, beneficial medical substances could be found in herbs, minerals and various alchemical combinations hereof. Paracelsus viewed the universe as one coherent organism pervaded by a uniting lifegiving spirit, and this in its entirety, Man included, was 'God'. His views put him at odds with the Church, for whom there necessarily had to be a difference between the Creator and the created.^[9]
