The Levitation Charm
Also known as a Sleeping Draught, this dark purple potion caused the drinker to fall into a deep and instantaneous sleep. Unlike the Draught of Living Death, this potion was less powerful and didn't last as long. However, it was still effective and could have a noticeable effect on its drinker. Hermione Granger used the draught to spike two chocolate cakes that she knew Vincent Crabbe and Gregory Goyle wouldn't be able to resist, and sure enough the pair fell immediately into deep sleep.
