Talk:History of herbalism

Confusing text....
Sorry, I'm not an editor, but I was confused by this part of the article:

'''17th century[edit] The second millennium, however, also saw the beginning of a slow erosion of the pre-eminent position held by plants as sources of therapeutic effects. This began with the Black Death, which the then dominant Four Element medical system proved powerless to stop. A century later, Paracelsus introduced the use of active chemical drugs (like arsenic, copper sulfate, iron, mercury, and sulfur).'''

Paracelsus I believe lived 1493 to 1541... why then does he seem to be active in the 17th century?
