Theophrastus Bombastus Von Hohenheim (Paracelsus) (1493–1541): The eminent physician and pioneer of toxicology

Theophrastus Bombastus Von Hohenheim known as Paracelsus was a German-Swiss homo universalis, or Renaissance man, whose interests included medicine, chemistry and toxicology. Characterized as a rebellious and great reformer of established medicine of his era, Paracelsus preferred observing nature, over studying ancient texts to find appropriate treatments for various diseases. He also used unconventional curative methods, such as minerals and other inorganic substances, which caused much controversy among his contemporaries. The main purpose of this article is to highlight his contribution on toxicology and the use of mercury.
