We will examine the definition of the phrases a taste of one’s own medicine and a dose of one’s own medicine, where these expressions came from and some examples of their use in sentences.
A taste of one’s own medicine and a dose of one’s own medicine are phrases that mean to give a sample of the suffering or unpleasantness bestowed by someone, back to the person who bestowed the suffering or unpleasantness. Giving someone a taste of their own medicine or a dose of their own medicine is retaliation, or sometimes it is justice. The expressions a taste of one’s own medicine and a dose of one’s own medicine are derived from a fable told by Aesop, who lived about 600 BC. In the fable The Cobbler Turned Doctor, a cobbler concocts a potion that he claims will cure someone of any type of poisoning. When the mayor of a town decides to challenge the cobbler to drink a poison and then take a dose of his own medicine, the cobbler admits his fraud. The moral of this fable is: Beware of those not trained in their craft.

“Of course, if they get wind of your Constitutional argument before you leave the scene of the crime, they could just give you a dose of your own medicine, administering vigilante justice with similar impunity.” (Forbes Magazine)
