Healing refers to a variety of special techniques used throughout the Dragon Ball series. Presumably mystical in nature, it allows the user to heal another being's wounds and restore them to full strength. In general, it appears to have the same effectiveness and limitations as the more commonly-seen Senzu Beans.
Dende is the first user of the healing technique in the series. During the Namek Saga, the elder Namekian known as Guru uses a technique to unlock the hidden powers of Gohan, Krillin and Dende; Gohan and Krillin gain a large boost to their power levels, while Dende gains the ability to heal.
Dende uses this ability several times during the Frieza saga. Most notably, he uses it to heal Vegeta after Krillin nearly kills the Saiyan prince; this was part of a desperate plan to give Vegeta enough power to destroy Frieza (as a Saiyan's power increases after recovering from a near-death experience). Unfortunately, Dende is targeted and killed by Frieza due to this ability.
After being revived by the Dragon Balls, and later being named Guardian of Earth during the Cell Games Saga, Dende uses this ability sporadically throughout the rest of Dragon Ball Z and Dragon Ball GT.
The Supreme Kai's aide and bodyguard, Kibito demonstrates his healing ability during the 25th World Martial Arts Tournament, where he heals Gohan after the latter has his energy drained by Spopovich and Yamu, the minions of Babidi. He uses it again to heal Gohan and the Supreme Kai before all three are teleported to the Sacred World of the Kais.
Majin Buu has the ability to heal organic beings, though it appears to be a variation of his Chocolate Beam rather than an entirely different ability. He uses this ability several times throughout the Majin Buu Saga to heal Babidi (who had earlier been bisected by Piccolo), cure an unnamed boy of his blindness, heal a dog named Bee, and bring Mr. Satan back from the brink of death.
- Porunga, the dragon of the Namekian Dragon Balls, restores Goku to full strength during the final confrontation with Kid Buu.
- Though his abilities are never shown, it is theorized that Denderot, a hypothetical Potara fusion between Goku and Dende, would be able to use Dende's healing technique.
