Force healing, Force heal, or Cure was a power that used the Force to accelerate the natural healing process rapidly, and could be used to heal the most fatal of wounds and injuries.
Initial levels required meditation, but greater aptitude usually granted faster regeneration, without need of meditation. Greater levels of attainment were also able to mend far more severe injuries, even major damage to flesh and bone and even going as far as to mend internal damage, such as damage to the heart, lungs, and so forth; even to the point of sustaining functions of lost organs and on rare occasions resurrecting dead tissue or even persons. This was shown in a more perverse form by Darth Vader, but was properly utilized by the most skilled of Jedi.
Jedi healers used this power to diagnose and treat the ailments of their patients. A notable case of this use of Force healing was Cilghal using the Force to cure Mon Mothma of a molecular poison that was incurable by conventional means, although, strictly speaking, the method of healing involved Cilghal’s Force-powered detection and removal of the nanomachines afflicting Mon Mothma rather than a direct application of Force energy against the damaged cells themselves. A variation of this power was Force Purification, as well as Force Assist which was a Force technique that enabled the user to heal people other than themselves, and with enough concentration, the user was able to heal others’ bodies and minds, simultaneously.
Practitioners were many, as were examples of its utilization: The least version of this power merely undid fatigue and was expected to be used by all Jedi after the New Sith Wars until Order 66. Ki-Adi-Mundi used this Force power to heal a broken collar bone almost completely by meditation after the ambush of Jabba the Hutt’s minions, during Mundi’s mission to find Sharad Hett. During the clone wars Anakin Skywalker tried and failed to use this ability, much to his frustration. He later was able to revive Ahsoka Tano, but only by using the dying body of the Daughter for more power. At least some members of a species native to Brodo Asogi possessed this technique, while the Jedi of the New Jedi Order used this ability in the form of a healing trance. Mara Jade was known to be able to fight through the pain she suffered by using a variant of the power that caused her to glow golden. After a lengthy and debilitating meditation, Luke Skywalker partly recovered from this trance by nearly immediately, resurrecting his own dead cells in preparation for combat.
Dark Lord of the Sith Darth Sidious, also known as Palpatine, was capable of using the light side for Force healing, as was Lord Wyyrlok.
