In the first Harry Potter novel, Professor Severus Snape hopes to embarrass Harry by quizzing him on the topic of bezoars. According to Snape, they are stony masses found in the stomach of a goat that can act as an antidote for most poisons. Later in the series, bezoars come to the rescue of a poisoned Ron Weasley.
The name bezoar is a derivative of both the Persian and Arabic languages, translating as “antidote” and “against poisons” – which is probably where J.K. Rowling got her inspiration. But many Harry Potter readers may not have realised that bezoars aren’t just a product of Rowling’s imagination.
