Healing (回復) 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 somewhat full strength. In general, it appears to have the same effectiveness and limitations as the more commonly-seen Senzu Beans. The only limitations to this is that it takes time for the user to heal, as they need to be at close range, while the Senzu Beans are able to be eaten anytime if available.
Dende is the first known user of the healing technique in the series. During the Namek Saga, the Namekian elder Guru uses one of his special abilities 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 by Vegeta in order to get a Zenkai boost to get enough power to destroy Frieza. Unfortunately, Frieza notices Dende's ability and decides to kill him.
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. Dende has moral issues when using his healing abilities on people that have evil hearts, and he only heals the evil if their intentions are good. It seems that Dende's healing extends to more than just the victim's wounds; when he uses it to heal Gohan while fighting Super Buu, it completely restored Gohan's tattered clothing (although, when Dende healed Piccolo after being "killed" by Frieza, Piccolo's clothes are not restored).
In the movie Battle of Gods, when Dende was healing Videl's leg, it is revealed that Dende's healing powers can also determine the life-signs of an individual he is healing as he noticed that Videl was pregnant.
Super Saiyan Goku
Main article: Ki Transfer
As a Super Saiyan, Goku shares his energy with Frieza to help him survive the injuries he gets after getting cut by his own Death Saucer. In the movie Dragon Ball Z: Cooler's Revenge, he brings a dead/injured bird back to life after Cooler killed it. As with Frieza, it may simply be that Goku gave the bird some of his energy.
Shin'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 Shin before all three are teleported to the Sacred World of the Kais.
Majin Buu has the ability to heal organic beings through his Mend Beam, alternatively known as Recovery Beam; a variation of the Chocolate Beam. He uses this ability several times throughout the Majin Buu Saga to heal Babidi (who had earlier been bisected by Piccolo), cure a boy named Tommy of his blindness, heal a dog he later named Bee, and bring Mr. Satan back from the brink of death. Apparently, it also restores the person's clothes if the injury in question also shredded the person's clothing, as Babidi also regained the torn parts of his outfit when Buu healed him of his bisection by the hands of Piccolo.
Super Saiyan God energy
As seen in Dragon Ball Super, the energy of the Super Saiyan God form is capable of healing the user's minor injuries, like battle bruises, or even lethal injuries, like being impaled through the chest.
Appearances in games
In the Dragon Ball Collectible Card Game, King Cold possesses the ability to heal his sons Frieza and Cooler. This is likely a reference to him finding Frieza in space after the battle on Planet Namek and having him rebuilt as a cyborg.
In Dragon Ball Z: Budokai 2, most maps in the Dragon World mode contain at least one Healing Spot. This is a space on the board colored blue with Dende standing beside it. For each turn a character spends on it, they gain an additional life.
Many support characters in Dragon Ball Z: Battle of Z have the ability to heal allies with specialized techniques, Jeice can use his Fighting Pose in order to create a healing sphere for his allies for example. Other healers in the game include Gohan, Krillin, Yamcha, Future Trunks, Android 18, Trunks, and Goten. Some characters can revive downed allies simply by hitting them. Teen Gohan's A Disturbance in Ki! is an example of this.

Dragon Ball: Xenoverse
In Dragon Ball: Xenoverse, Chronoa is shown to be able to use the healing technique as well, when she uses it to heal injuries Future Trunks' sustained during his fight with the Future Warrior while he was under the influence of Demigra's Dark Magic. Namekian Future Warriors can also heal their allies by using Emperor's Sign to slowly restore their health. Towa's Energy Zone Ultimate Skill can also heal its user and their allies.
