Symptoms and treatment
The symptoms of scale rot were scales taking on a dull, flakey appearance and falling off in large amounts. If left untreated in salamanders it could become severe enough that the tail would detach from the body.
For dragons, the treatment was to rub the affected area with a solution of salt water, tar and white spirit. The treatment for salamanders was to repeatedly rub the affected area with chilli powder.
In 1994, while searching for information that might help him to face his dragon during the first task of the Triwizard Tournament, Harry Potter encountered a mention of treating scale rot in a Hogwarts library book.
Behind the scenes
- Though only mentioned twice in passing in the Harry Potter books, the scale rot disease is described in detail on a page of notes concerning the book Dragon Breeding for Pleasure and Profit that is available on J.K. Rowling's Official Site. The scan of the page is available here.
