Bacta

Bacta was a thick, gelatinous slime that had healing properties. Injured individuals could be immersed in bacta-filled tanks in order to recover from their wounds more quickly. When the Alliance to Restore the Republic was stationed on the frozen planet of Hoth, Luke Skywalker had to be put in a bacta tank after being attacked by a wampa ice creature.
