Here’s a helpful, illustrative story to explain —the practice of protecting oneself against a poison by gradually ingesting non-lethal amounts, building up tolerance.

When Mithridates was finally defeated by the Roman general Pompey, he attempted to commit suicide by drinking poison rather than face capture. According to historical accounts (notably by Appian and Cassius Dio), the poison failed to kill him because of his acquired immunity. Frustrated, he was forced to ask his servant or bodyguard to kill him by sword or dagger. mithraditism
