"Dragon Blood can be used as an ingredient in potion brewing."
— Description[src]

Dragon blood was the blood of any of the many species of dragon.


It had a number of magical properties and was fairly expensive to buy bottled. It had twelve uses, the discoveries of which were typically all credited to the famous Hogwarts Headmaster, Albus Dumbledore,[6] although Ivor Dillonsby claimed that he had already discovered eight of them and that Dumbledore "borrowed" his notes.[7]

Three of the listed uses were as an oven cleaner,[3] spot remover[4] and a cure for verruca.[5]

Dragon blood seemed to have a notable taste, as Dumbledore was able to distinguish it from human blood by placing a small amount in his mouth in 1996. He was, however, the foremost expert on the substance, and the distinction may have been too subtle for anybody else.[2]

History of use

In 1995, Rubeus Hagrid used a bloody dragon steak to help with his injuries after being attacked by Giants during his ill-fated Mission to the Giant colony.[8]

The very next year, Horace Slughorn used dragon blood to try to fool Albus Dumbledore and Harry Potter, pretending to have been attacked by Death Eaters in the Muggle house where he stayed.[2]

Behind the scenes

  • In the Order of the Phoenix book and film, dragon blood appears to be green, but then in the Half-Blood Prince book and film, as well as Pottermore, dragon blood appears to be scarlet. However this could simply be explained by the blood having come from different breeds of dragon.
  • In the film adaptation of Harry Potter and the Half-Blood Prince, Dumbledore was able to tell from taste that the blood used was that of a dragon's, but in the novel, he had to ask Slughorn what it was.
  • In real life, the "dragon's blood" used in ritualistic magic and ancient medicine is actually a plant resin.[9]
