Mĭth'ri-dāte, n.

n. (Med.) An antidote against poison, or a composition in form of an electuary, supposed to serve either as a remedy or a preservative against poison; an alexipharmic;—so called from Mithridates, King of Pontus and Bithynia, the supposed inventor. [Love is] a drop of the true elixir; no mithridate so effectual against the infection of vice. Southey.
