His thought was colored by the fantastic philosophies of his time and he based his medical theories on the concept of human beings as microcosms of the universe. He was firmly opposed to the humoral theory of disease championed by Galen, and he advocated the use of specific remedies for specific diseases, introducing many chemicals (e.g., laudanum, mercury, sulfur, iron, and arsenic) into use as medicines. He also noted relationships such as the hereditary pattern in syphilis and the association of cretinism with endemic goiter and of paralysis with head injuries. Paracelsus wrote numerous medical and occult works containing a curious mixture of sound observation and mystical jargon. His work On Diseases of Miners was the first study devoted to an occupational disease.

Paracelsus (11 November or 17 December 1493 in Einsiedeln, Switzerland – 24 September 1541 in Salzburg, Austria) was an alchemist, physician, astrologer, and general occultist. Born Phillip von Hohenheim, he later took up the name Philippus Theophrastus Aureolus Bombastus von Hohenheim, and still later took the title Paracelsus, meaning "equal to or greater than Celsus", a Greek encyclopedist from the first century known for his tract on medicine. He is also credited for giving zinc its name, calling it zincum.
Paracelsus rejected Gnostic traditions, but kept much of the Hermetic, neoplatonic, and Pythagorean philosophies from Ficino and Pico della Mirandola; however, Hermetical science had so much Aristotelian theory that his rejection of Gnosticism was practically meaningless. In particular, Paracelsus rejected the magic theories of Agrippa and Flamel; Paracelsus did not think of himself as a magician and scorned those who did, though he was a practicing astrologer, as were most, if not all of the university-trained physicians working at this time in Europe. Astrology was a very important part of Paracelsus' medicine. In his Archidoxes of Magic Paracelsus devoted several sections to astrological talismans for curing disease, providing talismans for various maladies as well as talismans for each sign of the Zodiac. He also invented an alphabet called the Alphabet of the Magi, for engraving angelic names upon talismans.
Paracelsus pioneered the use of chemicals and minerals in medicine. He used the name "zink" for the element zinc in about 1526, based on the sharp pointed appearance of its crystals after smelting and the old German word "zinke" for pointed. He used experimentation in learning about the human body.
Paracelsus gained a reputation for being arrogant, and soon garnered the anger of other physicians in Europe. He held the chair of medicine at the University of Basel for less than a year; while there his colleagues became angered by allegations that he had publicly burned traditional medical books. He was forced from the city after having legal trouble over a physician's fee he sued to collect.
He then wandered Europe, Africa and Asia Minor, in the pursuit of hidden knowledge. He revised old manuscripts and wrote new ones, but had trouble finding publishers. In 1536, his Die grosse Wundartznei (The Great Surgery Book) was published and enabled him to regain fame. Paracelsus' life is connected to the birth of Lutheranism, and his opinions on the nature of the universe are better understood within the context of the religious ideas circulating during his lifetime.
He died, aged 48, of natural causes and his remains were buried according to his wishes in the cemetery at the church of St Sebastian in Salzburg. His remains are now located in a tomb in the porch of the church.
His motto was "alterius non sit qui suus esse potest" which means "let no man that can belong to himself be of another"
Paracelsus believed in the Greek concept of the four elements, but he also introduced the idea that, on another level, the cosmos was fashioned from three spiritual substances: the tria prima of Mercury, Sulfur and Salt. These substances were not the simple substances we recognise today, but were rather broad principles that gave every object both its inner essence and outward form. Mercury represented the transformative agent (fusibility and volatility); Sulfur represented the binding agent between substance and transformation (flamability); and Salt represented the solidifying/substantiating agent (fixity and incombustibility). For example, When a piece of wood is burnt, the products reflect its constitution: Smoke reflects Mercury, flame reflects Sulfur, and Ash reflects Salt.
The tria prima also defined the human identity. Sulfur embodied the soul, (the emotions and desires); Salt represented the body; Mercury epitomized the spirit (imagination, moral judgment, and the higher mental faculties). By understanding the chemical nature of the tria prima, a physician could discover the means of curing disease.
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 alchymical combinations hereof. Paracelcus 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.
He summarized his own views: "Many have said of Alchemy, that it is for the making of gold and silver. For me such is not the aim, but to consider only what virtue and power may lie in medicines." (Edwardes, p.47) (also in: Holmyard, Eric John. Alchemy. p. 170)
Hippocrates put forward the theory that illness was caused by an imbalance of the four humours: blood, phlegm, black bile and yellow bile. These ideas were further developed by Galen into an extremely influential and highly persistent set of medical beliefs that were to last until the mid 1850s. The dominant medical treatments at Paracelsus' time were specific diets to help in the "cleansing of the putrefied juices" combined with purging and bloodletting to restore the balance of the four humours. Paracelsus supplemented and challenged this view with his beliefs that illness was the result of the body being attacked by outside agents.
He wrote the major work On the Miners' Sickness and Other Diseases of Miners documenting the occupational hazards of metalworking including treatment and prevention strategies. He also wrote a book on the human body contradicting Galen's ideas
Paracelsus, sometimes called the father of toxicology, wrote:
That is to say, substances often considered toxic can be benign or beneficial in small doses, and conversely an ordinarily benign substance can be deadly if over-consumed. Even water can be deadly if overconsumed.
Many books mentioning Paracelsus also cite him as the origin of the word "bombastic" to describe his often arrogant speaking style. However, according to the Oxford English Dictionary, the origin of the word "bombastic" is not a play on Paracelsus's middle name, Bombastus. Instead, that dictionary cites "bombast": an old term for cotton stuffing.
