"...he knelt over Malfoy, drew his wand and traced it over the deep wounds Harry's curse had made, muttering an incantation that sounded almost like song. The flow of blood seemed to ease; Snape wiped the residue from Malfoy's face and repeated his spell. Now the wounds seemed to be knitting."

Vulnera Sanentur[1] is the song-like incantation of a healing spell and counter-curse to the Sectumsempra Spell, both of which were invented by Professor Severus Snape under his alias of "Half-Blood Prince"[3].


For maximum effect of the spell, the incantation had to be repeated thrice; firstly slowing the flow of blood to prevent death by exsanguination; the second to clear residue and begin to heal the wounds; and the third to fully knit the wounds, although dittany had to be applied to prevent scarring[3].

Known uses


Vulnera Sanentur derives from the Latin vulnus, "wound," (in which the roots of the English "vulnerable" may be seen)[4] and sanare, "to heal"; it is translated "may the wounds be healed."[5]

Behind the scenes

  • Body parts that had been completely removed with Sectumsempra could not be restored even using this spell.[6]
  • When Harry saw the damage inflicted onto Bill Weasley's face by the werewolf Fenrir Greyback, he suggested to Madam Pomfrey to heal him with a charm, being influenced by seeing how Snape used this spell to heal Draco, until he was notified that cursed wounds cannot be healed by charms.
  • In the book, Harry stayed in the bathroom after cursing Malfoy and witnessed Snape's use of the spell; in the film he ran straight to the common-room.
