Skele-Gro

Skele-Gro was a horrible tasting healing potion administered to witches and wizards to restore, mend or regrow their bones. Harry Potter took the potion when the bones in his arms were accidentally vanished by Professor Lockhart after a Quidditch accident. Fleur Delacour also administered the potion to Griphook at Shell Cottage, following the battle at Malfoy Manor.
