Rat tonic

A Rat tonic was a healing potion for rats. Apparently, it is used to treat ageing rats. It is sold in a small red bottle at the Magical Menagerie in Diagon Alley.^[1]

When Ron Weasley took his pet rat Scabbers to the Magical Menagerie because he looked ill, the witch behind the counter suggested Rat Tonic. Before Ron could pay, Scabbers was attacked and chased out of the shop by Crookshanks. Ron and Harry Potter followed. Hermione Granger stayed at the shop to buy Crookshanks and the Rat Tonic, which she later passed on to Ron.^[1]
