"She cleaned the cut with a dab of some purple liquid that smoked and stung, but then poked his shoulder with her wand, and he felt it heal instantly."
Madam Pomfrey attending to Harry Potter's wounds[src]

The wound-cleaning potion is a purple liquid that is used to sterilise wounds as a powerful antiseptic. It smokes and stings when applied. Madam Pomfrey used it on Harry Potter when he was injured during the first task of the Triwizard Tournament in 1994.[1]
