Search for the origin of this idiom and you’ll find the same answer again and again: “It comes from Aesop’s fables.” Some websites even tell a story about a fake doctor who is forced to drink his own medicine. It sounds perfect. The trouble is that it doesn’t hold up very well when you go looking for the evidence.
Quick answer: To get a taste of your own medicine means to be treated in the same unpleasant way that you have treated other people. It’s often said with a little satisfaction: “Now you know how it feels.”
Is it really from Aesop?
Aesop’s fables do include stories that make fun of fake doctors. In one well-known fable, often called “The Frog and the Fox” or “The Quack Frog,” a frog claims he can cure any illness. A fox asks why, if he’s such a great doctor, he can’t cure his own limp and his unhealthy skin. That’s a fun story, and it’s close in spirit to our idiom. But it’s about a doctor who can’t heal himself, not about someone receiving the same bad treatment he gave others. And the fable doesn’t contain our English phrase.
Other fables about quack doctors exist too, and you’ll see them linked to this idiom online. I couldn’t find any word historian who shows a clear line from those stories to the English expression. So treat the Aesop connection as a popular idea, not a proven origin.
What we can say: the online etymology dictionary Etymonline dates the version a dose of one’s own medicine to 1894. The picture is simple even without a fable. Medicine often tastes terrible. Imagine a person who keeps forcing bitter medicine on everyone around them, until one day someone makes them swallow it.
Picture three small scenes
- Sam always interrupts people in meetings. One day, the new manager interrupts Sam every time he speaks. Sam is getting a taste of his own medicine.
- Nina’s brother always reads her messages over her shoulder. So she reads his. She’s giving him a taste of his own medicine.
- A team that loves to trash-talk loses badly to a team that trash-talks even more. The fans say, “They got a taste of their own medicine.”
In every case, the treatment is the same kind of thing the person did. That matching is the heart of the idiom. If Sam interrupts people and later loses his job for a different reason, that’s not a taste of his own medicine. It’s just bad news.
What a dictionary won’t tell you: the smile behind it
This idiom almost always carries a feeling of justice, and often of quiet pleasure. When people say it, they usually think the person deserved it. That means:
- It’s great for stories, jokes and complaints among friends.
- It can sound unkind if you say it directly to someone who is upset: “Well, now you’ve had a taste of your own medicine!”
- Saying you want to give someone a taste of their own medicine means you plan to pay them back. In real life, that can make a conflict worse, so use it with care.
It can also be used about yourself, with humor and honesty: “I used to tease my dad about his bad jokes. Now my kids tease me. I’m getting a taste of my own medicine.” Said this way, it’s warm, not mean.
How to build the sentence
- get / have a taste of your own medicine: you receive it. “He finally got a taste of his own medicine.”
- give someone a taste of their own medicine: you do it to them. “She gave him a taste of his own medicine.”
- Match the possessive: my own, your own, his own, her own, their own medicine.
- “Dose” works too: a dose of your own medicine means the same thing.
Hear it in conversation
Elena: My roommate always leaves her dishes in the sink for days.
Omar: So what did you do?
Elena: I left mine there too. All weekend.
Omar: A taste of her own medicine! Did it work?
Elena: Not really. Now the kitchen just smells terrible.
Notice the ending. Revenge in English idioms doesn’t always end well!
Quick practice

Answers: 1. Yes. 2. No. This is a good thing coming back, and the idiom is used for bad treatment. (You could say “what goes around comes around” for both good and bad.) 3. Yes.
A Note from Daniel
What interests me most about this idiom is how it can mean different things. Sometimes people say it with satisfaction, sometimes with sympathy, and sometimes with a combination of feelings. When someone finally experiences what they’ve given to others, it’s rarely straightforward. It might change things, or it might not. But it always reveals something—what the behavior felt like, whether the person realized what they were doing, and if they can take that in and respond. If you’ve ever been on either side of this situation, giving or receiving, I’d truly like to hear your story.
