Gurdyroot Infusion is a purple beverage that is made by Xenophilius Lovegood and his daughter, Luna, out of Gurdyroot plants. Prior to the Ambush at the Lovegood House, Xenophilius offered Harry Potter, Hermione Granger, and Ron Weasley this drink. They drank it and thought it tasted horrible. It is described as "quite disgusting, as if someone had liquidised bogey-flavoured Every Flavor Beans".
