Skele-Gro

Skele-Gro is a potion which causes vanished or otherwise lost bones to regrow in a notably slow and painful process.

The potion comes in a large bottle and smokes as it as dispensed. Swallowing it burns the throat, and, according to Harry Potter, it tastes awful.

Harry Potter needed a dose of Skele-Gro when the bones in his right arm were broken during a Quidditch match in his second year; despite Harry's wishes, Professor Lockhart foolishly attempted to mend the bones, accidentally causing them to disappear instead.

Draco Malfoy mentions in his fourth year that he had previously attributed Hagrid's giant-like stature to a possible accidental overdose of Skele-Gro as a child; however, it is unknown if the potion could have such an effect.

Griphook the goblin was administered Skele-Gro by Fleur Delacour after the escape from Malfoy Manor.
