The Nightsisters of Dathomir utilized the Water of Life, a green fluid, for curative purposes. This elixir was made using a blend of water, minerals, tree sap, and tissue taken from the Sleeper. The creation of this mixture served as an initiation ceremony for those becoming Nightsisters. A Nightsister would need to use her Force powers to rouse the Sleeper, control it, and make it give up a piece of its own flesh. This bodily component would then be simmered in water sourced from the Nightsister fortress's deep pools, along with the other components. In the year 20 BBY, Mother Talzin led a group of Nightsisters in baptizing Asajj Ventress, formally inducting her into the Nightsister order.
Consuming this liquid could also temporarily amplify a Nightsister's Force abilities, particularly when summoning objects or animating zombies. In addition, it had the ability to resurrect individuals who had recently been slain, while also healing the wounds of the person brought back to life.
