Philippus Aureolus Paracelsus
     n : Swiss physician who introduced treatments of particular
         illnesses based on his observation and experience; he saw
         illness as having an external cause (rather than an
         imbalance of humors) and replaced traditional remedies
         with chemical remedies (1493-1541) [syn: {Paracelsus}, {Theophrastus
         Philippus Aureolus Bombastus von Hohenheim}]
