Cure for ague

"We are in the presence of a risk-taker! Quintia McQuoid would be proud — as most of you know, this Championship has been held in this garden every 7 years since 1407 in honour of Quintia McQuoid, that most memorable of potioneers, whose love affair with potions sadly came to an end with her untimely death from drinking an imperfectly-brewed cure for ague."

- The Wizarding Schools Potions Championship announcer. There is a potion that cures ague. If improperly brewed, this potion is potentially poisonous and could prove lethal.

In c. 1407, notable Potioneer Quintia McQuoid died after consuming an imperfectly-brewed cure for ague. In her memory, the Wizarding Schools Potions Championship has been held every 7 years since.
