Mithridatium

...putting into it Saccharum Buglossatum or triacle, or Mithridatium...

Until as late as 1786, the London physician could officially prescribe the Venice treacle or Mithradatium, a remedy that contained as many as 65 ingredients including the dried flesh of vipers.

A number of theriacs and mithridatia appear in the writings of ancient doctors, but it is rare to find an account of how one of them was used and the effect it had.
