You want the morph “Efficient Purge,” not the other one called “I’m Out of Resources.”
A good option for most trash, and absolutely vital in specific situations (most notably the Chickens and the Twins), useful in dungeons because it cleanses bleeds, fire, poisons, and other awful things. Remember that the cleanse will target any 6 players within 28 meters, not necessarily the ones who need it and not necessarily yourself. If you need to purge yourself, go for ritual first, then pop this if your group needs it.
Thank you to Harven for a wonderful little add-on that lets you see different morphs of a skill. Super handy!
